 tusely rounded, hind lobe finely, evenly 

 and densely punctate and with two 

 broad obtuse longitudinal ridges sepai*ated 

 by a shallow groove, the transverse im- 

 pression of front one ending in a loop 

 ^, each side. Scutellum with margins feebly

Paris, Me., June 11 (Frost). Sulli- 

 van Co., N. Y., Sept. 16 (Davis). 

 Chimney Gulch, Colo., Aug. 27. Hel- 

 ena, Mont., July 7 (Gerhard). Not as 

 yet recognized from Indiana but re- 

 corded from Ohio. Ranges from Quebec and New England west 

 to the Pacific ; not recorded in the east south of New Jersey, 

 though known from Texas, Arizona and New Mexico. It is a 

 cosmopolitan palsearctic species, common in northern Europe 

 and Japan. Van Duzee recognized nine varieties, based mainly 

 on color forms. Uhler (1876, 301) says that: "Like C. hyalinus 

 and C. lateralis it at times becomes suffused with a red color 

 which totally changes its appearance." In this country it has 

 usually been recorded as C. punctiventris (Dall.), a synonym.

 and more or less of disk of pronotum and an elongate spot on sixth 

 dorsal, usually more or less black: nervures of elytra with a few minute 

 brown spots; femora and tibia? with numerous small brown dots. Beak 

 reaching hind coxa?. Ocellar tubercles very small. Disk of pronotum 

 coarsely and rather closely punctuate. Abdomen with sides parallel, 

 the connexivum narrowly exposed, male; slightly widened behind mid- 

 dle, connexivum rather broadly exposed, female. Apex of last dorsal in 

 both sexes broadly rounded (fig. 58, a) . Length, 5 — 6 mm. 



Ft. Collins, Colo., June 17—30 (Osborn). Manitou, Colo. (U. 

 S. N. Mus.) . Recorded from District of Columbia by Barber 

 (1914a, 171). Its general range is western, extending from 

 Nebraska and the Dakotas to the Pacific. Uhler (1877, 407) 

 recorded it as a variety of hyalinus and stated that : "It lodges in
