Owing to the vastness of thεnumb 巴r of closely 町田mbling species ， the cl 呂ssification of the Calyptratae has givεn rise to many clisputes for several several decades 岨 Practically no two authors of th 邑 Diptera have agreecl either on the subject subject of major groupings or the Calyptratae or the principle of the cJ assification to be be used. In most of these works ，with the exception of Townsen c! 's paper (1 935-42) and few others ， the taxonomic criteria for generic and supergeneric classification have mainly been the external morphological characters of the adult flies ， ancl those for for specific c1 assification the characteristics of the genitalia of both sexes as well as the the adult external morphology. The larval charactεrs ，with the exception of Townsencl (1 935-42) ，HaU (1948) ，Roback (1 951) ，etc. ，have not been usecl to any great extent in in the classificatio l1 of the Calyptrate Diptera. Most of the systems proposecl until now have been mainly Eounded upon the characters of the vεnation ， the antennae ， chaetotaxy ，etc ，、 togεther with the genitalia. 1n the past ，th 日refore ， it is not too much to say that the family Iin lI ts within the Calyptratae as well as the subfamily or or tribal limits within one family of the same have been subject to much shifting. It is ， therefore ， clear that the co-orclinate comparison of the external and intemal morphological morphological characters at a11 the stages is to be more reliable than the results obtained obtained from a comparison only in the extemal m01 ・phology of the adult stage. キ The terms Schizometopa ， Thecostomata ，Muscomorpha ，Calyptrata ，Calypterata ，Calypteratae ， Calypterae ，Calyptrates ，Calypterates ，etc" are also used by Dipterists 個 - 215 日 216 216 Katsushig 昨日ORI works this line have not yet been carried out in this field of study 。 The pr 巴sent unde 1' took the comparative anatomy of the internal organs organs of the adult flies which had been igno 1' ed many p1' evlous Dipterists (1 960. 印刷; 1962a; 1962b). The results obtained from these works ，which a1' e based on 83 species ，were summarized here and the data of every trait were arranged in ascending ascending or descending orders to clarify ， if pos ヨible ， the relationships amcng the different different groups of the Calyptratae. Some impo 1' tant external charactε 1' s adopted by the form 色l' Di pterists such as the the the fourth the squamae ， the notopleurals ， the hypopleu 1' als ， though most of these we 1' e used for the separation of of families ， genera or for the past 100 years or more ， are here also shortly treated treated in discussin 史 this f1' om thεevidences of external as as welL Since the materials in th1S serIes of papers a1' e very limited ， the conclusions conclusions should be as purely tentative ，and ， the 1' efore ， a great great deal of additional detailed works on many more mate 1' ia1s ， especially those bεto the Scatophagidae ， Tachinidae (s. lat.) and sevεra1 other small small groups will certainly shed on this inte 1' esting but difficult Such detail 己d a1' e beyond the of my present work.

The systematic values of of thεse characters 疋 d th 色se pione 色rs in this field are of great imp のrtance and of general use even at the IJr 色sent time. The erection of the Calyptratae is accrεdited to Robineau- Desγoidy. He ，accorcling to 0 ョtenωSacken (1 896) ， divided the Myodair 巴s into nine gWclpS ，which he called families 日ntes) ，and the first of these ， on the basis of the laγge size of their squamae ，he called Calypteratae. This division ， however ，was not of later authors ， because it did not not in c1 ude the The first major work on the Calyptratae was done by Girsclmer (1 893) ，who oIf ered a new system of classification on the basis of many characters of of the adult fl i. es. In this system he fi. rst divided the Muscidae Calypterae into two families ， and Tachinidae ，on the basis of the presence or absence of the hypopleural hypopleural hris t1 es ロ This Girsclmer's system is not so vviclely different from the rεcent ones.
