or. all tihiae and tarsi dark and short although longer and more erect 

 on middle tibiae beneath. Dorsocentrals except posterior one, and 

 humeral bristles, weak and pale. Wings brownish but more intense 

 along costa and veins. 



Slender species, with nearly spherical head. Frons .25 width of head ; 

 orbits converging. Scutellum with well developed lateral and minute 

 cruciate apical, bristles. Lobes of fifth ventral large, broad with nar- 

 rowly rounded apices. Penult, section of fourth vein 1.25 as long as 

 post. c. v. and .3 as long as ult. section. Length — 7 mm.

\^ery similar to my determination of C. pleiiritica Lw., hut 

 here the pleura are pale without black area beneath the wings, 

 and the humeri are yellow on the lower half. The middle 

 tibiae with moderately long bristles and erect black flexor pile. 

 This may be C. rvunda Lw. and is probably closely allied to 

 the European albipcs Fall. 



Parallelomma vicina new species. 



$. Similar to diinindiata but the mesonotum with a broad, median 

 pale stripe which does not attain the base of the scutellum. Pleura with 

 a dark area beneath wings which includes the metanotum. Apices of 

 hind femora dark; pile on tibiae pale, very long and erect on flexor of 

 middle tibiae. Hypopygium dark. Wings infuscated at tips, especially 

 noticeable along veins 2. 3. 4. Cross veins narrowly clouded. Scutellum 

 without any trace of apical bristles. Lobes of fifth ventral broad and 

 broadly rounded at apices. Length — 6 mm. 



9. Similar but with no characteristic pile on tibiae: bristles of fore 

 legs strong; hind tibiae with 2 post, extensors.

Very similar to my determination of gracilipcs Lw., but 

 that species has no dark pleural spot and the pale mesonotal 

 stripe continues onto the scutellum ; the lobes of the fifth 

 ventral are very broadly truncate with emarginated apices. 



Scathophaga nigrolanata new species.
