174 CATALOGUE OF DIPTERA 



Drosophila tristis. Fall. 



The two first joints of the fore feet in the male are short and broad, 

 with a black edge ; the colour called by Meigen " testaceous" 

 appears from many instances to be a different shade from that 

 usually so named with us : in this insect it is almost a dull black : 

 the brown tinge at the tip of the wing is not very remarkable : the 

 eyes are fiery red : the abdomen, at least behind, is glossy black ; 

 but in all the females very soon after their appearance it becomes 

 from distention black, with a pale band at the base of each seg- 

 ment, and I doubt not that the Musea cellaris of Linne, is the 

 same, as his description agrees very tolerably with the female, 

 while no one could call the tinge of D. funehris, black. 



The present species is exceedingly abundant in autumn, 

 and not uncommon throughout the whole winter and early 

 spring. 



D. ingrata. 



Distinguished from the last by the broad and short hind shanks and 



feet. 



Only one female taken. 



D. melanogaster. 



Fore feet of the male have the 1st and 2d joint dilated, 



D. cameraria. Thorace testaceo opaco vittdfnsca, abdomine 

 rufo, incisurisfuscis. 



Resembles D. fenestrarum, but the opaque and more hairy head and 

 thorax at once distinguish it. 

 In windows in autumn. Bred from Boleti. 



Ephydra defecta. Nigro-cenea, scutello violaceo nitido, alis 

 obscur'is hyalino-gvUatis, anienms stibtus luteis. (Long. .08.) 



(To division B.) Seta of antennae pectinate : face silvery : semicircle 

 of the vertex steel blue: markings of the wings nearly as in 

 E. noctula : base of the metatarsi obscure yellow. 



E. pygmaea. Glauca, capite dor so prothorac'is et scutello 

 c'mereis, anteiinis et tarsis ferrugmeis. (Long. .05.) 



The face is not convex, but rather like a Notiphila ; but the massive 

 mouth and general character are more like Ephydra : antennae with 

 a dusky line above, third joint orbicular, seta short and pectinate :
