146 [July, 



60. Aphrosyltis mitis, u. sp. : A small species allied to A. ferox. 

 Antennae all black. Legs yellowish with the tibiae brown, and the 

 femora of the female brown. 



cJ. Palpi silvery with a slight yellowish tinge, smaller than in A. 

 ferox. Antennae small, blackish, third joint pointed but only as narrow 

 at the tip as the basal joint of the arista, the rest of the arista tapering 

 and rather longer than (or equal to) the rest of the antennae (including 

 the basal joint of the arista). Face whitish grey, extremely narrow at 

 the middle or the eyes touching. Lower postocidar bristles all short 

 and pale greyish yellow ; ocellar, fronto-orbital, and posterior vertical 

 bristles shorter than in A.ferax, and a short postocular row extending 

 half-way down the head. 



Thorax darker (browner) grey than in A. ferox. 



Abdomen with the genitalia hardly at all knobbed and with no 

 large lobe, small, greyish black but ferruginous and minutely pubes- 

 cent at the end. 



Legs luteous (compared with orange ferruginous in A. ferox), but 

 the tibiae all darkened ; coxae with a slaty grey hue except at the tip, 

 but reddish at the base of the front pair, which are glossed with 

 white anteriorly, and on which the tiny black anterior bristles may be 

 stronger but less numerous than in A. ferox ; front femora with one 

 black spine beneath at the base, but with the other tiny black bristles 

 not specialised and without any row of longer ones beneath (which are 

 present in A. ferox) ; front tibiae with one small dorsal bristle at about 

 one third from the base, and a small, inconspicuous apical spur, while 

 any dorsal or ventral ciliation is so slight as to be not noteworthy ; 

 front tarsi quite simple, slightly longer than the tibiae, basal joint 

 slightly longer than the next two together, and these two almost equal 

 in length, fourth joint the shortest ; middle legs simple, femora with- 

 out any of the bristles beneath which occur in A. ferox, though a slight 

 praeapical bristle occurs on the femora and two small bristles on the 

 tibiae at about one third from the base ; middle tarsi longer than the 

 tibiae, last joint hardly dilated ; hind legs thin and simple, femora 

 with a slight row of (about three) rather long antero-dorsal bristles 

 on the apical half, and the tibiae with a pair of bristles at about a 

 third from the base ; hind tarsi long and thin, basal joint only equal 

 in length to the next two together. 



Wings smoky ; costa with only short regular equal spines (as 

 distinguished from the Helomyza-like double i"ow of spines in A. ferox). 

 Squamae greyish brown ; halteres yellow.
