very small ; black bristles of the occipital row well-developed ; genal bristle weak ; 

 vibrissal edges bare. 



Thorax robust, with complete chaetotaxy and moreover with a black pp., which 

 is as strong as the scp. , and is wanting in all the other genera ; dc. very close to the 

 scutellum ; two mpl. ; pt. strongly developed. Scutellmn triangular, fiat, with four 

 bristles. iVbdomen broad and rounded, very convex, narrowed at the base and al- 

 most pedunculate, with short lateral and apical bristles ; ovipositor short truncate, 

 shorter than the two last abdominal segments together ; male genitalia not prominent. 

 Legs short and stout ; front femora with a row of bristles beneath ; the four posterior 

 femora with a row of short spinules below on each side : middle tibiae with two 

 spurs ; hind tibiae ciliated. 



Wings long, without costal bristle ; they are hyaline with a middle arcuated 

 brown cross-band and a large round apical spot of the same colour. All the veins 

 straight ; the first ending a little after the small cross-vein ; third bristly ; third and 

 fourth parallel ; the small cross- vein before the middle of the discal cell ; the posterior 

 cross-vein short and perpendicular ; second basal cell a little enlarged and hyaline ; 

 anal cell drawn out into a middle-sized point, which is as long as the second basal cell. 



Type : the following species. 



This genus is very distinct from any other and has no near allies ; it shows some 

 resemblance to D actis in general appearance and colouration as it does in the shape 

 of the second basal cell ; but has nothing to do with that genus. It is possible that 

 Dacus klu^ii of Wiedemann belongs here ; the Dacus icariis of Osten Säcken seems 

 to me undoubtedly a species of this genus, and some of Walker's species also. 



33. Callistomyia pavonina, n. sp. d' 9 . 

 (PL ix, fig. 36.) 



A handsome fly of proportionally great size, very distinct by its peacock-like 

 pattern of the wings. Length 8 — 9 mm., with the ovipositor. 



Head yellow, opaque, shining on the occiput, at the vertex and on the lower 

 portion of the face ; frons with two opaque dark spots, one, the greater, before the 

 ocellar black dot and the other which is smaller above the antennae ; a brown shin- 

 ing spot in the lower portion of the face at the middle of the epistome ; basal joints 

 of antennae dark reddish, with some black hairs ; third joint light yellow ; arista 

 dark. All the bristles black ; occiput below with a few short pale hairs and two or 

 three black stronger hairs above the genal bristle ; the first superior or. very weak 

 and short. Palpi and proboscis yellow, dark reddish above ; margin of eyes narrowly 

 white. 



Thorax tawny reddish, opaque, with yellow pubescence, the pleurae almost bare ; 

 three narrow black longitudinal stripes on the dorsum, the laterals sometimes abbre- 

 viated ; a short black streak in the notopleural region and above this a yellow spot. 

 Pleura reddish, darkened on the mesopleura and with an arcuate yellow band, which 

 is formed by a horizontal streak on the superior margin of the mesopleura connected 

 with a vertical streak on the anterior margin of the pteropleura ; hypopleura yellow,
