C anipla Erichg. — Oval, more obtuse in front, piceous, sparsely pubes- 

 cent. Thorax feebly emarginate in front, sides feebly arcuate and but little 

 narrowed anteriorly, margin narrowly reflexed but not explanate, hind angles 

 obtuse, surface moderately closely punctate. Elytra gradually narrowing 

 posteriorly, margin feebly reflexed, apices separately rounded, more oblique 

 in the male, surface substriately punctate, sparsely pubescent, without erect 

 setse. Length .24^.28 inch; 6 — -7 mm. 



The male has the head larger than the female and the thorax 

 broader in front, the elytral apex oblique. 



This species differs from the next two by its much larger size, 

 uniformly piceous color. 



Occurs in the Middle, Southern and Western States, not rare. 



C sti'igata Fab. — Oval, broader in front, piceous, moderately shining, 

 sparsely pubescent, and with short erect setae. Thorax nearly twice as wide 

 as long, sides gradually arcuate and narrowed to the front, hind angles rect- 

 angular, margin not explanate, narrowly reflexed, color piceous, margin paler, 

 eurface not densely punctate, sparsely pubescent and with a few erect setae. 

 Elytra very little longer than wide, sides feebly arcuate and gradually nar- 

 rowed to apex, margin very narrowly reflexed, color piceous and with two 

 transverse sinuous fasciae more or less interrupted and a scutellar spot pale 

 testaceous, surface sparsely pubescent and with seven series of short erect 

 setae the outer rather irregular. Body beneath piceous, sparsely punctulate. 

 Length .10— .14 inch; 2.5—3.5 mm. 



Occurs in Europe and our Atlantic States. 



C. concinna Mels. — This species is more regularly oval, less narrowed 

 posteriorly; the color is similar to strigata, differs also in having the sides of 

 the thorax moderately explanate and the elytral margin wider and more re- 

 flexed. The sinuous fasciae of the elytra are usually entire, sometimes inter- 

 rupted by the suture. Length .08 — .12 inch; 2 — 3 mm. 



In both these species the elytra are obliquely prolonged in the 

 male, obtuse in the female. 



With this species I unite G. hella Reitter, which does not differ 

 from the Melsheimer species, concinna | Reitter, seems to be a mere 

 color variety of strigata. 



Middle States, Kansas, Texas. 



IPS Fab. 



Labrum connate with the epistoma, suture more or less evident. 

 Front slightly prolonged. Mandibles stout, bifid at tip. Prosternum 

 prolonged at tip, never attaining the metasternura, anterior coxje open 

 behind. Antennae with an abrupt club, grooves moderately deep, con- 

 vergent. Tarsi dilated or not, claws simple. 



There is an additional segment in the male, but often so much 

 retracted as to be invisible. 



Here is a proper occasion to call attention to the labrum. All
