DROSOPHIUD/E WITH PARASITIC LARVit 167 



lum gray, irregularly mottled with brown, two pairs of strong rticirginal 

 bristles, the apical pair cruciate. Pleurae pruinose pale gray, with two 

 incomplete, transverse, brownish black stripes, one beginning just below 

 the humeri, the other crossing the middle of the mesopleurae. Abdomen 

 dorsally with the second segment gray pruinose, a blackish spot medianly 

 and large ones basally toward sides ; third, fourth, and fifth segments dull 

 blackish, with broad pale gray pruinose apical and lateral margins, sixth 

 and seventh segments mostly pale gray ; surface of segments with coarse 

 and rather sparse, evenly distributed black hairs, a submarginal row on 

 fourth segment and a margined row on fifth distinctly coarser and longer ; 

 venter pale. Legs psJe ochraceous ; middle and hind pairs with a dark 

 spot on the femora ventrally close to apex, the tibiae with a dark ring 

 near base. Wings hyaline tinged with gray, the veins brown ; anterior 

 cross-vein well beyond tip of first vein ; posterior cross-vein weakly sinu- 

 ate, placed well outwardly, the last section of the fourth vein about one- 

 third longer than the penultimate ; third vein gently arcuate beyond the

Honolulu, Hawaii, July, 1907, reared from meaJy bugs {Pseudococ- 

 cus) on sugar cane (Otto H. Swezey) and from Pseudococcus common 

 on shrubs and trees, sent by Wm. Weinrich, Jr., in 1 902 (adults issued 

 August 28, 1 902, Bureau of Entomology) ; Manila, Philippine Islands, 

 reared from larvae feeding upon Pseudococcus (G. Compere) ; Philip- 

 pine Islands, reared from Pseudococcus (California State Insectary).

This species strongly suggests in its general appearance Drosophila 

 repleta. It appears to be widely distributed in the Orient. A series of 

 poorly preserved specimens, collected by Prof. H. Maxwell-Lefroy at 

 Pusa, India, is before me. In this species the male has a coarse serrate 

 comb on the first three joints of the hind tarsi. It would also seem that 

 the absence of the second weak pair of dorsocentral bristles is a peculi- 

 arity of the male, but more material is needed to determine this point. 

 Titanochaeta, new genus. 



Frons over one-third the width of head. Postvertical bristles long, 

 cruciate; three pairs of orbital bristles, inserted near eye-margins, the 

 anterior pair stout and proclinate, the median pair small and reclinate, the 

 posterior pair very large, reclinate and situated about at middle of frons, 

 behind it two small bristles ; ocellar bristles very long and stout, procli-
