Coleoplera. 121 



the metasternum, very closely punctured, opaque, and destitute of 

 pubescence, iledian triangular area of the metasternum deeply 

 depressed and very sharply marked off from the closely punctured 

 lateral areas. Antenna? reaching a little beyond the apex of the 

 elytron, with the third joint almost equal in length to the three 

 following joints taken together, and distinctly thicker than any of 

 those joints. Anterior tibia? nearly straight, scarcely curved 

 towards the apex; first joint of anterior tarsi not quite so long as 

 the two succeeding joints taken together. 



JPrinobius ceramensis, Lansb. (I^otes Leyden Mus., vol. vi, p. 148), 

 seems to have many characters in common with the present species, 

 but as the author in his description states that the antennae are 

 shorter than the body, and has not called attention to the relative 

 proportions of the joints, nor has pointed to any unusual character 

 in the hind coxse, it is safe to assume that the species is quite 

 distinct. 



Zooblax elateroides, Thoms., from the Andaman Islands, also has 

 certain affinities with the present species. 



Family CERAMBYCIDiE. 



79. Ceresium quadrimaculatum, Gahan, sp.n. 



Mgrum, antennis pedibusque (clavis femorum nigris, preetcrmissis) 

 ferrugineis ; pronoto fortiter subrugoso-punctato, maculis quatuor 

 f ulvis ornato ; elytris sat sparse punctatis et albo-setosis. 



Long. 11-13, lat. 3-4 mm. 



Black, with the antennae, tibiae, tarsi, and the bases of the 

 femora reddish brown. Head coarsely punctured ; antennae more 

 than half as long again as the body, with the third joint a little 

 longer than the first or fourth, but distinctly shorter than the fifth ; 

 fifth and following joints as far as the tenth sub-equal in length to 

 one another, the eleventh longer than the tenth. Trothorax nearly 

 one-third longer than broad, strongly and thickly punctured, and 

 somewhat rugose, especially towards the sides ; with a faint patch 

 of fulvous pubescence on each side, and with four distinct fulvous 

 spots above, two of which are near the anterior, two near the 

 posterior, margin. Elytra black, glossy, not very closely punctured, 

 with the punctures diminishing in size towards the apex, and each 

 bearing a short, decumbent yellowish-white seta. 



Taken in the central part of the island, and also near Flying 

 Fish Cove. 



In colour tliis species resembles C. nigrum, Gah., though 

 differing in having the thickened portion of the femora black, 

 and in having foiu" distinct tawny spots on the pronotum. It is, 

 however, easily to be distinguished by structural differences. In 

 C. nigrum the pronotum is as broad as it is long, and is scarcely 

 punctured towards the sides ; the femora, especially those of the
