pliagus, Bolbocems, and other genera, as a specific rather than a generic 

 character. 



IschiopsopJia violacea, n. sp. 



Elongate and depressed above ; deep violet-blue, very shining, darker and 

 inclining to black in some lights, antennae, palpi, tarsi and apex of the tibiae 

 of a greenish tinge. 



Head slightly widened in front, the side margins a little raised in front of 

 the eyes, the puncturation very s^jarse at the base, closer on the disc, and 

 becoming finer and more dense towards tbe apex, the clypeus very deeply 

 notched and with the lobes sub-acute. Prothorax convex in front and somewhat 

 flattened behind, very broad and almost as wide in the middle as at the base ; 

 strongly narrowed in front, the anterior angles produced and acute, basal angles 

 rounded, basal lobe large and slightly emarginate at its apex, the disc and basal 

 surface smooth, remotely punctiired in front and towards the sides, the punc- 

 tures closer and inclined to form striae towards the anterior angles, the lateral 

 margins naxTOwly raised. Elytra sub-depressed, slightly narrowed to the 

 middle and rather more strongly so behind, separately rounded and slightly 

 reflexed at the apex, abruptly and strongly deflexedat the sides, the basal third 

 or foiirth either quite smooth or with indistinct rows of remote punctures 

 merging posteriorly into a transverse striation, which becomes denser behind, 

 but ceases at the apical callus. Pygidium transversely arcuate and sharply 

 carinate at the apex, upper surface closely strigose, under-side concave and 

 feebly strigose. Under-side of the body strigose on the pro- and raeso-sternum, 

 front of the meta-sternum, hinder part of the posterior coxae, and sides of the first 

 abdominal segment ; the rest of the surface smooth or very remotely punctured, 

 a very finely striated stridulating convexity at the sides of the second, third and 

 fourth abdominal segments, the first four segments with a large chalky -white 

 spot on the exposed iipper-sides ; meso-sternal process long and gradually 

 narrowed to the apex. Legs strigose and punctate, anterior tibiae in both sexes 

 with two marginal teeth and the prodviced apex all acute, the four hinder tibiae 

 with a thin fringe of black hair. Length 28-30 mm.

This fine species most nearly resembles I. durvillei H. and J. in 

 coloration and sculpture, but is of a more elongate and parallel- sided 

 form, has a longer and narrower sternal process, and conspicuous 

 stridulating prominences on the abdomen in both sexes ; the elytra are 

 also more strongly and abruptly defiexed at the sides, although not so 

 sharply as in I. virens H. and J. The dozen specimens received from 

 Mr. Meek show no variation in the peculiar coloration of the species.
