PASCOE O N T H E COLEOPTERA O F PENANG. 507 punctured; prothorax closely punctured, transverse, broader than the head, its sides rounded, and only very imperfectly margined, the disk with a median elevated longitudinal line not extending to the apex or base ; scutellum small, subtriangular ; elytra much broader than the prothorax, closely punctured, the punctures larger than elsewhere, and occasionally confluent, two slightly elevated longitudinal lines on each; body beneath brown; legs brownish ferruginous, slightly hairy; antennae about half as long as the body in the female, in the male probably longer than the body, as in P. anten-natus, Gyll. (P. inconspicuus, W . W . Saund.). Philus was referred by Mr. Saunders to the Prionidar, near Erio-derus and Tragosoma ; but I think it is more correctly placed by M. J. Thomson with the true Lepturinar, near Centrodera and Vesperus. The marginal costa, marking the separation of the prothoracic pleurae from the pronotum, one of the most important characters of the Prionidar, is almost obliterated in the species just described, and, according to M. Thomson, there is not the least trace of it in another species from Northern India described by him (P. globulicollis). Philus antennatus, Gyll. (Schon. Ins. App. p. 280), is an old Chinese species, with which Mr. Saunders's P. inconspicuus is said to be identical. STENODERINJE. DEJANIRA. Dejanira, J. Thomson, Syst. Ceramb. p. 134. DEJANIRA QUADRIPUNCTATA, J. Thomson, I. c. M. Thomson's specimen of this fine Longicorn and one in mv own collection are from Java. The antennae of the female are only about two-thirds the length of the body. DEJANIRA BIAPICULATA. D. rufo-ochracea ; elytris in medio oblique fulvo maculatis, apice singulis biapiculatis. Reddish ochraceous; head and prothorax covered with a rich golden-yellow silky pubescence, the vertex with a short keel between the eyes, and a few punctures; spines of the prothorax moderately produced, triangular, the disk irregular, with two antemedian sub-approximate tubercles; scutellum black, narrow, rounded behind, slightly grooved in the middle; elytra rather narrow, finely punctured, covered with a short dense pubescence, an oblique yellowish patch on each towards the outer side, the apices shortly biapiculate ; body beneath with a delicate yellowish pubescence; legs slender; antennae reddish ochraceous ; eyes black. Length 7 lines. There are three specimens, or perhaps species, in Mr. Lamb's collection, all differing in the prothorax, but otherwise, allowing for the usual differences in sex and size, apparently identical. It would be necessary to examine a larger series before this can be decided; and therefore I will only mention here that one of the three has a |
