tarsi of female not conspicuously widened (Dejeaniopina) 



Dejeaniops gen. nov. 



Palpi much widened on apical half, gradually narrowing basally, densely ciliate 



with long hair; proboscis short and stout; parafacials bare; front tarsi of female 



strongly widened (Lasiopalpina) Lasiopalpus Mcq. 



3. Palpi narrow, gradually narrowing basally, ciliate with long hair; proboscis 



slender and conspicuously longer than head-height; parafacials hairy; abdo- 

 men emarginate anally (Dejeaniina : Eulasiopalpise) . . . Eulasiopalpus gen. nov. 

 Palpi not ciliate 4 



4. Palpi gradually widened from base distally, proboscis short; abdomen sub- 



quadrate and conspicuously emarginate anally; front tarsi of female strongly 



widened (Paradejeaniina) Paradejeania B. & von B. 



Palpi of even width on distal two-thirds or more; proboscis elongate and slender 

 (Dejeaniina : Dejeaniise and Eudejeaniise) 5 



5. Discal spines on dorsum of intermediate abdominal segments (Dejeaniise) 



Dejeania R.D. (Africa) 

 No discal spines (Eudejeaniise) 6 



6. Abdomen subquadrate and deeply emarginate or buttocks-like behind in both 



sexes; front tarsi of female widened Eudejeania T. 



Abdomen subovate, not broadly buttocks-like behind, at most the hind border 

 of anal segment half as long as greatest width of abdomen and gently emargi- 

 nate in female; front tarsi of female not widened 7 



7. Abdomen clothed with strong bristles in addition to the spines and differentiated 



therefrom, front tarsi of male with bristly hairs on inside 



Echinotachina gen. nov. 

 Abdomen with only pubescence in addition to the spines 8 



8. Pubescence short and normal Adejeania gen. nov. 



Pubescence long, dense, even and pronounced, showing conspicuously among 



the spines, thorax also with a dense pubescence. . . . Trichodejeania gen. nov. 



Below is a statement of the genera and their types. Whether 

 all these forms belong in one natural tribe remains to be decided 

 by a careful intensive study of the group and its allies. Although 

 it would seem probable that these elongate palpi are not all of 

 common origin, yet none of the forms exhibits any striking depart- 

 ure in its external anatomy from the general characteristics of the 

 group. A comparative study of the first-stage maggots, which 

 the writer has in hand, will conclusively demonstrate the actual 

 affinities. 



Dejeania R. D. (1830) — Type, Stomoxys bombylans F. (equals 

 Tachina bombylans Wd., and Dejeania capensis R.D.).
