little outside the vibrissae, separated by a reddish downward pro- 

 longation of the transverse impression. Engel's description and 

 figure supply sufficient details. 



I leave Wiedemann's supposed female, really a male of Belvosia, 

 without further identification, as it is in poor condition. 



88. ZENILLIA THERMOPHILA Wiedemann 



Tachina thermopMla Wiedemann, Auss. Zweifl., vol. 2, 1830, p. 325. 

 Sisyropa thermopMla Beaxjee and Bekgenstamm, Denk. Wien. Akad. Wiss., 

 vol. 56, 1889, p. 163 ; vol. 58, 1891, p. 344 ; vol. 60, 1893, p. 113, 122. 



One male, " thermophila Wied. Java," and " Coll. Winthem," also 

 red " type " label. I asked to see this Java specimen in order to 

 assure myself about the status of the genus /Sisyropa, this being the 

 type species. 



The genus was established by Brauer and Bergenstamm in 1889 

 (p. 163), with only this species. In 1891 (p. 344), the authors 

 gave a synopsis of a dozen species, from Java, Europe, Australia, and 

 Brazil, prefacing with the remark, " We should probably have done 

 better to unite the species of this genus with those in the genus 

 Farexorisfa, with which, as also with Ghaetolyga, they have the 

 head structure in common." In 1893, however, they place Sisyropa 

 in the section Blepharipoda (p. 122), and Parexorista in section 

 Masicera (p. 113). 



Since the standing of the genus depends entirely (aside from 

 questions of priority) upon the characters of the type species, these 

 will be briefly enumerated. The head of the specimen is obviously 

 shrunken, so micrometer measurements are of doubtful value. 



Male, front moderately wide, face considerably wider but not 

 widening very much below middle; front not prominent, face mod- 

 erately receding ; cheek probably about one-sixth the eye height in 

 normal specimen; parafacial bare, very narrow below; vibrissae at 

 oral margin; clypeus wide, facial ridges bristly only one-fifth of 

 the way. Ocellars small, proclinate, parallel; frontals about 10, 

 the uppermost pair large and reclinate, succeeding ones small, then 

 gradually larger near antennae, the lowest almost at level of arista; 

 one or two smallish bristles outside the main frontal row near 

 antennal insertion. Antennae reaching four-fifths of the way to 

 the oral margin, third joint of medium width, a little more than 

 twice the second ; arista slender, only a little thickened on proximal 

 half, basal joints short. Palpi normal, proboscis short, fleshy. 



Thoracic chaetotaxy: acrostichal, 3, 3 (damaged, a little uncer- 

 tain); dorsocentral, 2, 4; humeral, 3; posthumeral, 2; presutural, 

 2; notopleural, 2; supraalar, 3; intraalar, 3; postalar, 2; sterno- 

 pleural, 2, 1 ; pteropleural minute ; scutellum with 4 lateral, 1 rather 

 large depressed apical, 1 discal.
