coloration, but none can be called large. They may be best recog- 
nized by the constriction at sides of the thorax and by the partly 
united claws at the base. 
The larvae of the European species are remarkable for making 
a covering: out of their own excreta ; this is facilitated by the 
apex of the anal segment which is turned upwards; the frass is 
pushed forward little by little and hardens over the upper surface 
of the larva. This covering is, however, discarded when the 
larvae bury themselves in the ground to pupate, a cocoon being 
substituted for it. 
Section I. 
Fulvous. Thorax not longer than broad , with single transverse 
basal sulcus; elytra metallic blue or green; labrum blade. 
22. Lema obliterata, sp. n. 
Head and thorax fulvous, antennae and legs paler, labrum black : 
elytra metallic greenish-blue; underside black. 
Head dark fulvous, impunctate, the vertex highly raised, the 
elevation divided by a deep groove, each division broadly rounded 
above ; labrum black ; antennae pale fulvous, joints two to four 
gradually elongate, following joints longer. Thorax dark fulvous, 
with strongly widened and convex anterior portion, deeply con- 
stricted ; lateral excavation scarcely wider than the basal sulcus, 
bounded by a short ridge above, the basal groove very deep ; 
surface impunctate. Scutellum black, subquadrate. Elytra with 
a deep fovea or excavation below the base, the latter raised ; 
shoulders bounded within by a deep sulcus, the latter strongly 
punctured ; rest of the surface very finely punctate-striate, the 
punctures rather distantly placed. Breast and abdomen black ; 
legs fulvous, slender and elongate.

The very deep elytral depression and their sculpture will easily 
separate this species from others with similar coloration ; the 
shoulders are very prominent and bounded on both sides by 
a deep sulcus.

Eulvous ; labrum black ; elytra dark metallic blue ; underside 
fulvous. 
Head with the intraocular space strongly swollen and finely 
punctured, lateral sulci very deep ; labrum and upper part of 
clypeus black, the labrum with some transversely-placed 
punctures. Antenna) rather more than half the length of the 
body, entirely fulvous ; fourth joint very slightly longer than 
the third, the following joints elongate, cylindrical, and not 
increasing in thickness. Thorax scarcely longer than broad, deeply
