COLASPOIDES NIGRIPES. 19 



and deeply punctured at the outer disk where the inter- 

 stices form strongly raised transverse rugosities , which ex- 

 tend through the entire length of the elytra ; the apical 

 portion shows some longitudinal costae near the suture. 

 Legs unarmed. 



Eight specimens were captured at Paja Koemboeh, Solok 

 and Rengkiang Loeloes (Sumatra-Expedition). 



From similarly sculptured species , the present one is at 

 once distinguished by the black underside and legs. 



Colaspoides apicicornis^ n. sp. 



Broadly oblong. Below dark fulvous, stained with me- 

 tallic green. Antennae pale fulvous, two last joints fus- 

 cous. Above metallic green. Thorax finely and closely 

 punctured. Elytra subgemiuate punctate-striate , the inter- 

 spaces at the sides and apex costate. Anterior and poste- 

 rior femora toothed. — Length 3 lines. 

 Var. Above obscure cupreous. 



Head very finely and remotely punctured, sometimes nearly 

 impunctate, finely strigose close to and above the eyes. 

 Epistome separated from the face, with a distinct groove, 

 extending from its apex to the vertex of the head, broadly 

 triangular, strongly punctured posteriorly, its anterior mar- 

 gin moderately concave-emarginate. Labrum fulvous. An- 

 tennae nearly two thirds the length of the body, slender 

 and filiform , entirely fulvous , the last 2 apical joints only 

 fuscous. Thorax more than twice as broad as long, the 

 sides regularly rounded and narrowed anteriorly, anterior 

 angles very acute and slightly produced ; surface rather 

 closely and finely punctured, the punctuation a little 

 stronger near the sides. Scutellum broadly ovate. Elytra 

 strongly punctate-striate , the punctures arranged in distinct 

 double rows towards the suture where they are rather 

 finely impressed , towards the sides they are much larger 

 and more strongly marked; the interstices at the same
