1866.] MR. F. P. PASCOE ON THE COLEOPTERA OF PENANG. 509 



the two lateral teeth, the five middle nearly forming a quincunx, the 

 two foremost of which are elevated and conical ; scutellum elongate, 

 triangular ; elytra very irregular, longitudinally marked with irregu- 

 lar raised lines, with smaller transverse lines between them, and 

 rather finely punctured, the brown principally forming three large 

 patches on each ; body beneath dark glossy chestnut-brown ; legs 

 yellowish, shining, the femora at the base, band on the clava, and 

 apex of the tibiae brown ; antennas yellowish, the first six joints very 

 glossy, the rest pubescent, opake, the apex of the third beneath, the 

 fourth almost entirely beneath, and the sixth at the apex generally 

 tufted with dark fulvous hairs. Length 4|-11 lines.

NoEMIA. 



No'emia, Pascoe, Trans. Ent. Soc. ser. 2. iv. p. 111. 



Noemta flavicornis, Pascoe, I. c, pi. 22. f. 8. 



Found also by Mr. Wallace at Singapore and Sarawak. A speci- 

 men from the latter locality has a slender vertical spine on each side 

 of the mesosternum, immediately above the coxa. 



NOEMIA CHALYBEATA. 



N. toto eyaneo-chalybeata ; capite transversim sulcato et punc- 

 tato ; elytris apicibus bimucronatis. 



Entirely bright steel-blue, with an almost imperceptible greyish 

 pile ; head finely and closely punctured, behind the eyes the punc- 

 tures occasionally contiguous, forming slight transverse grooves ; 

 prothorax covered with small closely crowded irregular punctures, 

 the apex transversely striated ; scutellum scutiform, concave, finely 

 punctured ; elytra strongly punctured at the base, gradually be- 

 coming impunctate posteriorly, the punctures in rows, the alternate 

 rows separated by a raised line, the apices bimucronate, the outer 

 mucro produced ; body beneath glabrous ; legs with a few scattered 

 hairs ; antennae nearly linear, about half as long again as the body. 

 Length 10 lines. 



A fine species, very distinct, inter alia, from the others hitherto 

 described in its mucronate elytra, a peculiarity which would put it 

 out of the genus as M. J. Thomson has defined it. The above de- 

 scription is from one of Mr. Wallace's specimens taken at Sarawak. 



Necydalinje. 



Merionoeda.

Merionceda acuta. 



M. capite nigro ; prothorace luteo ; elytris longiusculis, testaceis, 

 extus niyro limbatis ; antennis articulis penultimis et ante- 

 penultimis fiavidis, cceteris nigris.
