Yol.XXvii] ENTOMOLOGICAL NEWS. 



Eyes widely separated, dark bronzy brown, finely pubescent ; ocellar 

 tubercle slightly raised, usually paler by denser pollinosity, the an- 

 terior ocellus inclined on its front edge ; no frontal triangle, but a 

 prominent slightly sunken narrowly oval dark marking, laterally pale- 

 bordered, extending forward from anterior ocellus ; orbits pale gray, 

 those of the front sometimes tinged with brownish-yellow ; the front 

 produced, broadly snout-like, over the base of the antennae, this pro- 

 duced and rounded area being pale dull brownish-yellow, with several 

 rows of recumbent and convergent hairs ; a pair of post-ocellar bristles, 

 erect, converging, their points crossed; these, with a pair of erect and 

 divergent outer verticals, are the strongest of the head bristles, which 

 are black, usually from black bases. 



Antennae large, directed laterally, appressed to head; the first joint 

 bidden, the second broadly bell-shaped, yellow often partially ob- 

 scured with dark and with a marginal row of spur-like hairs from black 

 bases; the third joint much enlarged, longer than broad, rounded api- 

 cally, basally on inner side dull salmon-yellow, sometimes ferruginous, 

 the remainder dark purplish gray, almost black, and both joints thinly 

 and finely white pollinose ; arista black and tapering, shortly and sparse- 

 ly haired. The cheeks produced in advance of the face, in color pale 

 dull brown sometimes varying to and always merging into the gray of 

 the posterior orbits ; cheeks conspicuously marked with black dots 

 which form the bases of recumbent forward-pointing hairs ; a pair of 

 well-differentiated brown vibrissal hairs ; the black dots continued in a 

 regular row around the posterior orbits. Face black ; clypeus and well 

 defined median carina pale. Mesonotum with a narrow black median 

 stripe (a dull black area destitute of pollen) extending to scutellum. 

 two similar lateral stripes abbreviated slightly in advance of scutellum, 

 and two short dark markings above the wing bases. On each side two 

 humeral bristles, one to two anterior and two posterior notopleurals, 

 two post alar and one pre-scutellar ; the uppermost anterior notopleural 

 weak and apparently sometimes missing. 



Scutellum broad, rounded, almost semi-circular in outline, discally 

 flattened, in color and texture like the mesonotum, but laterally broadly 

 darker; marginal scutellars black, four pairs distinguishable; median 

 pair best developed, their points approaching or crossed. 



i Inheres long, club-shaped, white, unmarked, their stems sometime^ 

 darkened to almost black. 



Wings transparent, unmarked, iridescent, their surface rouglu-ne 1 

 with minute evenly distributed rasp-like hairs; veins dark brown; an- 

 terior edge closely set with short bristly hairs directed obliquely for- 

 ward, gradually merging into the short fine e\ en-leii^ili fringe; the 

 costal thickening obvious to V I plus 2 (4th longitudinal) ; axillary in- 

 cision very deeply out, its extremity rounded, separating from the rest
