640 CONNECTICUT GEOL. AND NAT. HIST. SURVEY. [Bull. 



fuscous to black but irrorate with paler spots, outer basal margin 

 greenish ; apex of mesocorium bordering inner basal angle of 

 cuneus fuscous, with black spot on corio-membrane margin, the 

 pale spot at apex of corium not extending upon cuneus. Mem- 

 brane suggestive of erectus by having two fuscous areas each side 

 on apical half, but differs by having central area fuscous as well 

 as the basal area more broadly blackish. 



Legs : Rather similar to those of erectus but differs in having a 

 clearly defined, although narrow subapical pale annulus on hind 

 femora. 



Venter : Blackish, pale beneath but rather narrowly on genital 

 segment; genital claspers (fig. 139) distinctive of the species, 

 exhibiting a close relationship with buenoi. 



Holotype: Male, 12 Aug., 1921, Mendon, Mercer County, Ohio (R. F. 

 Hussey) ; author's collection. Named in honor of the collector, Mr. R. F. 

 Hussey.

Male: Length 5.8 mm., width 2 mm. Resembles eximius but 

 the colors of the dorsum are more in contrast ; front and middle 

 femora dark fuscous brown, closely and irregularly maculated with 

 pale ; black patch bordering the cubitus strongly contrasted with 

 the pale spot which joins the base of cuneus, pale part of cuneus 

 tinged with roseous ; central area of membrane distinctly pale; 

 genital claspers and flagellum (fig. 149: 14) distinctive of the 

 species. 



Female: Very similar to the male in size and coloration. 



Occurs on Norway Spruce (Picea).

Proc. Calif. Acad. Sci., ser. 4, ix, 345, 1920. 



Male: Length 5.4mm., width 2mm. Head: Width .94mm., 

 vertex .36mm. Antennae: segment i, length 1.16mm., more 

 broadly pale than in hussey i\ ii, 2.5 mm.; iii, 1.28 mm.; iv, 

 1.2 mm. Pronotum: Length .87 mm., width at base 1.56 mm. 



Very similar to husseyi in size and coloration, the pale areas of 

 dorsum more uniformly brownish, cuneus reddish, and hind 

 femora without distinct subapical pale band. Genital claspers very 

 distinctive (fig. 149: 5).

Bull. Brook. Ent. Soc, xv, 58, 1920.

 antennal segment ii uniformly infuscated except the pale annulus 

 at base ; apical half of corium and bordering the claval vein, dis- 

 tinctly olive green; flagellum and genital claspers (fig. 149: 12) 

 distinctive of the species.
