angles not at all distinct, more shining than the head; disc dis- 

 tinctly earinate in the middle line posteriorly and impressed on 

 either side; puncturation very close, much finer than on the head, 

 almost imperceptible; pubescence very line. Elytra parallel, 

 longer than the thorax, longer than broad, puncturation very fine, 

 close and asperate; pubescence fine and close. Abdomen a little 

 widened posteriorly, densely and very finely punctured, pubescence 

 fine and close; apex reddish-testaceous. 



Hah. Mandai, on the bank of a stream. Four females. 

 29. Calliderma rufum, n. sp. 



Rufous, elytra reddish-brown ; head and abdomen shining, thorax 

 opaque; antennae and legs pale reddish-testaceous. Length 

 5-li mm. 



Near C. indicum, Kr., but larger and differently coloured, the 

 head longer in front of the eyes, the basal impression much broader, 

 and the abdomen more coarsely punctured. Head shining, elongate, 

 distinctly longer than the breadth including the eyes, the sides 

 parallel in front of these; temples small, strongly rounded and 

 passing insensibly into the base; the vertex posteriorly with a deep 

 semi-circular impression, from which on either side a sulcus passes 

 outwards to the orbit, and another, much wider behind, forwards, 

 nearly reaching the apex of the broad smooth triangular space 

 between the anteimal tubercles; this space, the sulci, and the basal 

 impression, glabrous and highly polished, the rest of the surface 

 in front of the orbital sulci coriaceous, with a few large superficial 

 setiferous punctures; the surface behind the orbital sulci and the 

 temples without ground-sculpture, but with obsolete setiferous 

 puncturation. Antennae with the 1st joint as long as the live 

 following joints together, the 2nd to the 5th longer than broad, 

 gradually decreasing in length, the 6th and 7th moniliform, the 8th 

 to 10th slightly transverse. Ilth short, oval. Thorax opaque, a 

 little longer than broad, slightly broader than the head, widest 

 just before the middle, the sides obtusely angulate at this point, 

 from thence rounded and converging anteriorly, sinuate and more 

 strongly converging posteriorly; disc in the middle line behind 

 with a short, shining longitudinally sulcate carina, and on either 

 side with a sinuated, elevated line extending from the posterior 

 to the anterior margins, but not coalescing either with them or with 

 the median carina : the extreme cutis of these lines are shining, and 

 except for these and the median carina, the whole of the surface 

 is opaque, densely and finely punctured; the sides with a few
