Show 1897.] OP THE FAMILY ENDOMYCHID.E. 459 on the apical side, and the posterior fascia is also less sharply indented than those in T. senegalensis. This is the smallest Trycherus I have yet seen. A single female example. ENCYMON CINCTIPES, n. sp. (Plate XXXII. fig. 4.) Niger, nitldus, fere glaber ; prothorace transverso, lateribus slnuatls, angulls posticis rectls ; femorlhus juxta apicem rufo-cinctls. Long. 9 millim. o* $ . Mas: abdominis segmentum aplcale levlter emarginatum. Hab. B U R M A , Ruby Mines (Dohertg). Head smooth but uneven, owing to the raised antennal ridges : antennas rather long, their basal joint as long as the third, the fourth to eighth gradually decreasing, about half the length of the third. Thorax not twice as wide as long, smooth, with deep basal sulci, which reach half the length ; the width in front, across the prominent angles, is about equal to that of the base, but the sides widen a little. The elytra are decidedly oblong, not so convex nor so much rounded on their sides as in E. immaculatus or E. femails; the sutural stria is distinct, but nearly vanishes at the apex, their margins are but narrowly expanded. The underside is black, the abdomen rather dull, the apical segments are a little pubescent and the apex punctured, and this appears to m e more so in those examples which have a slight notch, and which from analogy I assume to be the males. I can see no difference in the tibiae. The femora are rather distinctly clubbed, and are red for about a third of their length over the thickest part. This species is perfectly distinct from E. ferlalls. The thorax is wider, and the form is more oblong and not so convex as other species allied to it. There are seven examples before me from Fry's collection. ENCYMON VIOLACEUS, Gerst. Perak (Doherty). This insect has a wider range than I should have expected. I have lately seen examples from the Karen Mountains (Fea); and it varies in the colour of the elytra, the one before m e from Perak having them nearly black with a faint green reflection. ENCYMON REGALIS, Gorham, Trans. Ent. Soc. 1874, p. 440. Var. pedibus totls nigris. Mas: tlblls anticis et Intermedlls Intus Infra medium minute denticulatis ; abdominis segmento aplcall angulatlm emarglnato, basi medio suhelevato. Perak, low country (Dohertg). Two specimens, a male and a female, in Mr. Fry's collection present the characters of the insect described by m e from the Philippine Islands, with the exception of the colour of the hinder legs. One being a male, I am able to give the sexual distinction. The emargination of the last segment will be found useful in other species in which the tibias are simple or nearly so in both sexes. |
