and the tarsi fulvous, thorax strongly and remotely punctured, 

 elytra deeply punctate-striate, the interstices more or less lon- 

 gitudinally costate, claws appendiculate. 



Length 2 lines. 



Head very convex, the vertex remotely but strongly punctured ; 

 the supraocular sulci also distantly punctured, with some silvery 

 hairs at the margins, epistome separated from the face by deeply 

 punctured lateral grooves , its surface also strongly punctured , 

 its anterior margin nearly straight, labrum fulvous or piceous, 

 palpi fulvous , antennae with the lower six joints fulvous , the 

 others dark purplish blue, broadly dilated, thorax one half broader 

 than long, the sides straight at the base, slightly rounded before 

 the middle , the anterior angles acutely produced , the surface 

 strongly and remotely punctured with some smaller punctures 

 on the interstices , elytra without basal depression , with nine 

 rows of deep punctures which are sometimes disturbed by extra 

 punctures, the sides with about five longitudinal costae, legs 

 metallic greenish or cupreous, the tarsi dark fulvous. 



Hab. Sipora. 



A very small species of which three specimens were obtained, 

 it is much smaller than C. multicostata , Jac. from Borneo and 

 has the costae at the sides only and the punctured rows much 

 wider apart ; in one of the specimens which seems to be the 

 female sex, the elytral punctures are often doubled, but this 

 seems to be the only difference, in the third specimen the colour 

 of the upper surface is nearly black with purplish or green 

 patches, the underside in all is very dark, the sides of the breast 

 and abdomen being varied with metallic green. 



HALTICINAE. 



8. Sphaeroderma tristis, n. sp. — Black, the seven lower 

 joints of the antennae flavous, thorax finely and closely punc- 

 tured, disc of elytra closely and irregularly, the sides regularly 

 punctured.
