account of the closer punctuation. Scutellum impunctate. Elytra 

 very convex, very dark purplish, subopaque ; the punctuation not 

 differing from that of the other parts, but closer and arranged in 

 almost regular rows near the suture, more confused near the sides, 

 where a costa runs parallel with the lateral margin ; the apex of 

 the tibiae and the tarsi fulvous, rest of the legs dark biovvn. 

 Mus. Jacoby.

IS. CoLASPIS FULVILABRIS, Sp. DOV. 



Oblong. Below bluish black, shining ; legs and antennae (three

 rather closely and deeply jmnctate ; antennfe testaceous, joints 

 6-8 piceous. Thorax convex, distinctly" tontlied at the middle of 

 the lateral margin, in front of which the latter is widened ; anterior 

 angles tliickened, posterior ones acutely toothed ; surface distinctly 

 foveolate at each side, deeply and irregularly punctured. Elytra 

 fonvex, scarcely wider at the base than tiie thorax, puuctured like 

 the latter, but the punctures more evenly distributed ; interstices

19. COLASPIS NIGRIPENNIS, Sp. nOV. 



Black, antennae and legs testaceous ; thorax bisinuate at the 

 sides, and, as well as the elytra, finely punctate. 



Length 4 hues. 



Head with deep oblong punctures between the eyes and a narrow 

 longitudinal central groove ; clypeus and the vertex more sjjaringly 

 punctate ; labrum fulvous ; antennae nearly as long as half the body,

 obsoletely bisinuate at the lateral margin, surface with a deep fovea 

 at each side ; surface distantly and finely punctate, the punctures 

 near the sides deeper but not more closely placed, the interstices at 

 the same place also very minutely puuctured when seen under a strong 

 glass. Scutellum finely longitudinally striate. Elytra parallel, 

 moderately convex, punctured like the thorax, but more regularly 

 striate, except near the lateral margin, where the puncturing be- 

 comes more confused. Underside black with a bluish tint, legs
