G. squaniiilata Crotch, Proc. Acad. 1873, p. 36.— Very like albida, but with 

 the entire surface densely clothed with elonjjate white scales. The thorax is 

 decidedly wider at base than at middle ; in fact, the sides are regularly arcuately 

 narrowed from base to apex. Length .25 — .30 inch. ; 6.5 — 7.5 mm. 



The claws are moderately strongly cleft a little iu front of the 

 middle. 



Occurs in Oregon, California, Utah and Arizona. 



G. cryptica Say, Jour. Acad. iii. p. 449 ; edit. Lee. ii, p. 215. — Head coarsely 

 punctate, front scarcely impressed. Thorax widest at base, sides feebly arcuate 

 and gradually narrowed to the front. Elytra acute at tip and slightly prolonged, 

 the apices slightly divergent; surface scarcely metallic, vestiture not dense and 

 composed of scale-like hairs. Length .30 — .35 inch. ; 7.5 — 9 mm. 



The claws in the specimens before me are absolutely simple, without 

 trace of tooth. 



This species has been re-described by Dr. Baly (Trans. Ent. Soc. 

 Lond. 1865, p. 334) as albicans, without a knowledge of the locality. 

 Jacoby (Biol, vi, pt. 1, p. 177, pi. vii, fig. 4) records the species from 

 Mexico, on the authority of a specimen obtained from Salle, and 

 part, originally, of the Sturm collection. The locality is doubtless 

 an error. It is due to Jacoby to note that he observed the simple 

 claws of this species. 



Occurs in Missouri, Kansas and Dakota. 



COLASPIDEA Lap. 



It has been stated that three species until now enrolled as Glyp- 

 toscelis should be separated from that genus by their broad and flat 

 prosternum and a feeble trace of an antennal groove on the outer 

 angle of the prosternum. From the descriptions of Chapuis and 

 Lefevre studied conjointly there seems to be no reason why they 

 should not be referred to Colaspidea, the species of which are fi'om 

 southern Europe and the circum-Mediterranean region generally. As 

 our three species are from California, the distribution may seem pe- 

 culiar, but this is merely one of many instances of genera repre- 

 sented in Europe and our Pacific regions without representation in 

 the Atlantic region. 



The species are separable as follows : 



Sides of thorax feebly arcuate; pubescence of surface sparse and inconspicuous. 



Bright brassy in color; tibiie always paler than the femora CtiprasceilS. 



Cobalt-blue, or slightly greenish; legseutirely black bronzed. .sniaragdulus. 

 Sides of thorax strongly arcuate; pubescence of surface well marked. 



Color blue, green or bronze; thorax more coarsely and closely punctate than 

 the two preceding varicolor.
