COLASPOIDES NIGRICORNIS. 21 



transversely rugose; towards the outer portion of the apex 

 a very short costa is visible. Legs stout, metallic green 

 like the rest of the underside. Femora simple. 



Several specimens. — They are from Loeboe Tarab , 

 Moeara Laboe , the District of Rawas and Koetoer (Suma- 

 tra-Expedition), 



The closely and strongly punctured head in connection 

 with the black antennae will distinguish the present spe- 

 cies. 



Colaspoides sumatrensis , n. sp. 



Oblong-ovate, convex, entirely fulvous. Two apical joints 

 of the antennae obscure fuscous. Thorax closely and finely 

 punctured. Elytra more strongly punctate-striate , the inter- 

 stices flat. Femora without teeth, — Length l^/g — 1^'4 line. 



Head impunctate. Epistome not separated from the face 

 at its apex which is narrowed and rather elongate, caused 

 by the depressions at each side , limiting the encarpae ; 

 surface impressed with a few fine punctures. Antennae 

 three-fourth the length of the body, the terminal joints 

 slightly thickened , all the joints with the exception of the 

 second, of nearly equal length. Thorax transverse, nearly 

 three times as broad as long, the sides regularly rounded 

 and not much deflexed in front, surface closely impressed 

 with fine oblong punctures. Elytra without any basal de- 

 pression , closely and rather strongly punctate-striate at 

 their anterior two-thirds , more remotely . punctured near 

 the apex , the interstices not costate but very slightly 

 wrinkled near the sides. 



Three specimens from Silago (Sumatra-Expedition). 



I separate this species from C. parvula Baly , to which 

 it seems closely allied , on account of the close punctuation 

 of the thorax and that of the elytra which in the allied 

 species are described as »foveolate-punctate". The two ter-
