Records of Btus. 261 



fulvous hair; exirenie apices of tibiae slightly fenugiuou-, 

 the legs otherwise black, with pale yellowish hair; hiiul basi- 

 tarsus not greatly broadened. The hair of the abdomen 

 between the bands, which in most species is black, i-ifuloous, 

 and as it is long and overlaps the bands, it makes them 

 appear yellower than they otherwise would ; sixth dorsal 

 segment descending almost perpendicularly, and then abruptly 

 bending to the strong lip, the descending portion covered with 

 long fulvous hair. 



A very distinct species, not closely related to any other, so 

 far as I am aware.

Me<jachile anoijric, sp. u. 



? . — Length 11 to 12 mm. (13^ with the head thrust 

 forward). 



Black, rather robust, with greyish-white pubescence; the 

 abdomen shining, with narrow white entire hair-bands, that 

 on first segment broader and enlarged at sides; ventral scopa 

 white, entirely black on the last two segments ; claws with a 

 strong basal bristle, but no well-developed tooth. Head and 

 thorax densely punctured, with copious greyish-white hair ; 

 on the clypeus the hair is a shade greyer and thin, showing 

 the shining and strongly punctured surface ; margin of 

 clypeus normal ; matidibfes j^^culiar, sJiort and thick, with an 

 apical blunt toothy and a lo?ig straight cutting-ed(je beyond; 

 cheeks rounded ; eyes sage-green ; tegulie very dark brown. 

 Wings only moderately dusky ; second r. n. joining second 

 s.m. very near its end. Legs black, with light hair, that on 

 inner side of tarsi fuscous or reddish fuscous ; ajncal corners 

 of middle tarsal joints with pectiniform spines or bristles; 

 hind basitarsus not greatly broadened. Abdomen between the 

 bands, and the sixth segment, very shiny, with coarse bhick 

 hair; sixth segment wholly without pale hair and not rapidly 

 descending. 



A pretty and distinct species, rather like Af. generosa, 

 Cresson, but easily separated by the wholly light hair of 

 vertex and mesothorax and other characters.
