NORTH AMERICAN COLEOPTERA. ■ 289 



Through the kindness of Mr. Jacoby I have been enabled to study 

 a specimen of Batophlla rubi, and have been forced to the conchision 

 tliat Batophila and Glyptina cannot be retained as distinct, as there 

 does not seem to be any structural difference. 



All the European species are said to be apterous, this is the case 

 also with hicolor, which in turn resembles Podagrica in its color. 

 Following this cyanipennis has similar colors, and while the body is 

 feebly winged, the elytra are united. The pale species which follow 

 on have better marked humeri and well developed wings, but this is 

 not an abrupt transition as spuria has but feeble humeri. 



The elytral striie are confused at apex and sides in bicolor, while 

 in the three following species the striae are entire and regular, while 

 in the last two species the sides and apex are quite smooth. 



It seems to me that Crotch was correct when he united Glyptina 

 and Batophila, but he seems to have overlooked the fact that Glyp- 

 tina has the right to priority. 



The species may be readily distinguished by the following table : 



Elytra blue, with metallic lustre. 

 Head and thorax reddish yellow; humeri indistinct. 



Thorax somewhat wrinkled, vaguely punctate; elytral strife much confused 



- at apex bi(>oIor. 



Thorax smooth, very sparsely, finely punctate; strise entire, not confused. 



cyanipennis. 



Head and thorax shining black ; humeri distinct nivalis. 



Elytra yellowish of rufotestaceous ; humeri wider than thorax. 

 Elytral striae of well defined punctures, the lateral strije distinct. 



Lateral strije, especially the ninth, deeper than those of the disc; body be- 

 neath brown brnnnea. 



Lateral striije faint; body beneath brownish piceous, very rarely pale. 



spuria. 

 Elytral strife of very fine or obsolete punctures, sides and apex smooth. 

 Elytral striae of extremely fine punctures; body beneath always pale. 



cerina. 



Elytral strife of coarse, obsolete punctures near the base and scutellum only ; 



body beneath piceous or nearly black atriventris. 



G. bicolor n. sp. — Oblong oval, more narrowed in front, convex, beneath 

 piceous ; head, thorax and legs pale reddish brown, elytra bright bluish green, 

 metallic. Antennse with basal joint brown, next three rufotestaceous, outer 

 .joints piceous. Head impunctate. Thorax one-third wider than long, narrower 

 at apex, sides arcuate, anterior angles slightly obliquely truncate, disc convex, 

 the surface somewhat wrinkled, the punctuation very indistitict and rather fine. 

 Elytra not wider at base than the thorax and very nearly continuous in outline, 

 surface shining, confusedly punctate at apex, striato-punctate at base and sides,
