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 

 larva? 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 Uack. 



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. 



Length 6 mm.

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.

Zeit. 1903, p. 23. 



Fulvous ; 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. Antennae 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
