FAMILY XXXVIII. — BELOSTOMATID^E. 



Fig. 210. Natural size. 

 (After Garman. Hemiptera of 

 Connecticut) . 



Vigo and Marion counties, Ind., October; Orizaba, Mexico, 

 July (W. S. A'.). Chicago, 111., June (Gerhard). Ranges from Que- 

 bec and New England west to British Columbia and Colorado 

 and southwest to Florida, Texas and Mexico. The only definite 



Florida record is that of Barber (1914) 

 from Jacksonville. Like B. griseus, 

 which it resembles very closely in size 

 and color, it is attracted to electric 

 lights, my Orizaba specimens having 

 been taken in the gutter beneath an arc 

 light. Its habits, as far as known, are 

 the same as those of B. griseus. 



1183 (1389). Lethocerus obscurus (Du- 

 four), 1863, 383. 

 Elongate-oval ; sides of vertex subparallel. 

 Above dull brownish-yellow, more or less 

 mottled with wavy fuscous lines; under sur- 

 face fuscous-brown, the pro- and mesosterna 

 paler; legs dull yellow with fuscous mark- 

 ings more evident than in americanus. Ver- 

 tex wider and more convex than there. Front 



femora narrower, its groove more shallow. Length, 40 — 45 mm. ; width. 



17—18 mm. 



Staten Island, N. Y., and Washington, D. C, June {Dans). 

 Chicago, 111., May (Gerhard) . Ranges from Massachusetts west 

 to Illinois. Recorded also from Utah. Smaller, more slender 

 and parallel, and usually of a darker hue than americanus. 



1184 (1391). Lethocerus uhleri (Montandon), 1896, 513. 



General color dull brownish-yellow; vertex, except extreme base, a 

 broad stripe each side of front lobe of pronotum, greater part of hind 

 lobe, scutellum except sides, base of clavus and inner half of corium, dark 

 fuscous-brown; middle and hind legs distinctly annulated with pale and 

 dark rings; front femora dull yellow, vaguely striped or tinged with fus- 

 cous; front tibiae and tarsi fuscous-brown. Interocular area about as 

 wide as eye, obtusely carinate, its sides parallel. Pronotum trapezoidal, 

 its side margins straight and converging from base to apex; disk of 

 front lobe with a median impressed line; of hind one and scutellum with 

 a vague, narrow median carina. Connexivum narrowly exposed. Front 

 femora moderately broad, deeply and narrowly sulcate. Length, 40 — 48

Marshall Co., Ind., June 11. Ft. Myers and Dunedin, Fla., 

 March— April ; at electric light (W. S. B.) . Mobile, Ala., August

 Florida stations and apparently the most common species in
