PachylopJithalmus signatus Meig. Voria ruralis Fall, (setosa B. B. 

 type) shows somewhat often some ciliae at the root of the 5th uervure 

 of the wing, etc., but the most embarrassing instance is to be found in 

 species with very variable coloration, such as Ehinia apicalis Wied., 

 R. niyricornis Macq., and K. testacea Eob. Desv., which one would take 

 for varieties of one kind if certain $ individuals were not pilose on the 

 thorax and scutellum, whereas in others this pilose covering is reduced 

 to the same degree as in the . One meets also with examples of the 

 common Tachina fallax Meig. in which the eyes are distinctly hairy 

 (var. pseudofallax Villeu.). I have seen also a J of TricJiolyga 

 sorbillans Wied. in which the hairiness of the eyes is short and scattered, 

 although the example is perfectly well preserved.

SUB-FAM. TACH1NINAE. 

 GEN. DEJEANIA Eob. Desv. 



DEJEANIA NIGRAPEX, n. sp. 



A robust species. Same coloration as _D. bombylans Fab., from 

 which it differs in several characters : abdomen with the three first 

 segments entirely yellow and totally without discal setae ; fourth seg- 

 ment black and bristling with prickly hairs except on a narrow, yellow, 

 barren anterior band ; wings uniformly greyish without any rufous 

 baud towards the base ; palps yellowish, thick all along the length, 

 covered with small black hairs without long setae, they reach the end 

 of the proboscis, which is shiny black ; antennae and chaetae dark 

 brown ; second joint of the chaeta little elongated, plainly shorter than 

 in D. bombylans. Sternopleural setae = 1 + 1 ; no fine setae on the 

 genae ; no orbital setae in the $ . 



Length 15-16 mm.

PLEEOPELETEEIA, n. sub-gen. 



A pair of discal setae a little in front of the marginal setae on 

 segments 2 and 3 of the abdomen in the manner of the sub-genus 

 Cliaetopeleteria B. B. The $ has several orbital setae. On the genae 

 there is an entire row of erect setae in front of the eyes and as well 

 developed as the frontal setae, the latter belonging to the ascending
