than body, joint 1 stout, subcylindrical, 2 thickened toward 

 apex, more so in female ; pronotum elongate-trapezoidal, broad- 

 er at base than long, otherwise as in key ; scutellum triangular, 

 equilateral, convex, with a transverse groove across basal third ; 

 elytra dimorphic, in macropterous male longer than abdomen, 

 clavus deflexed to corium, the latter subconvex, cuneus long 

 triangular, feebly deflected; hind tarsi with joint 2 longest, 1 

 shortest. Three species have been recorded from North 

 America, two of them from our territory. 



KEY TO EASTERN SPECIES OF GLOBICEPS. 



a. Elytra of female reaching behind middle of abdomen with membrane 

 short but distinct; second antennal thickened toward apex in both

915. FLAVOMACULATUS.

 cuneus and membrane ; second antennal of male but slightly thick- 

 ened toward apex ; base of vertex not margined in either sex. 



916. DISPAR. 



915 (1161). Globiceps flavomaculatus (Fabricius), 1794, 182. 



Black, sparsely clothed with short silvery-white hairs; elytra with 

 costal margin pale dull yellow, blackish at base; corium with a large 

 triangular yellowish-white spot on basal half, and a dark brown band 

 across apical fourth, cuneus with basal half yellowish-white; membrane 

 blackish, iridescent, inner cell and spot near tip of cuneus whitish; legs 

 reddish-brown, tibiae and tips of femora usually paler. Joint 1 of anten- 

 nae brownish-yellow, as long as width of vertex; 2 black, male, paler at 

 base, female, four times as long as 1 ; 3 and 4 piceous, 3 two-fifths the 

 length of 3, twice as long as 4. Length, 5 — 6 mm. 



(British Mus. Coll.). A palsearctic European species recorded 

 in this country from Ontario and doubtfully from Pennsylvania, 

 but Knight (1922, 281) states that these records require veri- 

 fication. Common in England in July on Umbellifera and 

 amongst roots of grasses. 



916 ( — ). Globiceps dispar (Boheman), 1852, 72. 



Male — Elongate, subparallel. Black, vertex often with a pale spot 

 each side; clavus and apical half of corium pale fuscous, cuneus and 

 basal half of corium pale translucent, the former with apex and inner 

 margin dusky; membrane pale fuscous, cells whitish, iridescent, veins 

 darker; legs straw-yellow, hind tibiae and third joint of tarsi dusky; ven- 

 trals black, shining. Joint 1 of antennae dull yellow, as long as width of 

 vertex; 2 black, paler at base, four times as long as 1 ; 3 yellowish, dusky 

 toward apex, three-fifths the length of 2; 4 fuscous, one-half as long as 3.
