are not very dense punctures. Elytra elongate-oblong, not 

 much wider than prothorax; with dense and not very large, 

 but sharply-defined punctures, becoming larger and more or 

 less confluent at basal third. Abdomen rather sparsely clothed 

 along middle, apical segment rather strongly incurved to 

 middle of apex, with a wide but rather shallow median impres- 

 sion. Femora stout, front pair strongly dentate, the hind pair 

 less strongly dentate but conspicuously angulate, middle pair 

 unarmed ; hind tibiae long, lower-surface at about one-third 

 from apex with an acute tooth, the line of the tibiae then 

 altered ; four front tarsi with basal joint somewhat inflated, 

 claws each with a stout basal appendix. Length ( d , 9)> 

 6-6J mm. 



9 . Differs in having abdomen more convex, more regu- 

 larly clothed along middle, apical segment not transversely 

 impressed, femora less stout, hind tibiae unarmed on lower- 

 surface, and the apical curvature regular, and the tarsi with 

 basal joint less inflated.

The front angles of the prothorax as seen from the sides 

 appear to be rather acutely produced, but from below they 

 appear like large conical teeth, very different to those of any 

 other species of the genus, but the prosternal episterna have 

 the front edge quite straight, although slightly oblique, the 

 front coxae are very close to the front of the presternum, and 

 not much more distant from the base. On the male the basal 

 joint of antennae, most of the eleventh and the tips of some of 

 the others are infuscated ; on the female the basal joint and the 

 apical half (or more) are infuscated ; the knees, trochanters, 

 and claws are usually of a dingy-red, but sometimes are scarcely 

 paler than the adjacent parts. My reference of the species to 

 Edusa may be called in question. The general outlines, from 

 above, are much as those of several species of Megasceloides, 

 but the dentate femora and hind tibiae should exclude the 

 species from that genus. 



Edusa griffithi, n. sp. 



S . Brassy or bronzy, under-surface sometimes with a 

 vague greenish gloss ; parts of labrum, of palpi, of antennae, 

 and of legs, of a more or less dingy-red. Rather lightly (more 

 densely on parts of under-surface than elsewhere) clothed with 

 white pubescence, becoming scales on elytra. 



Head shagreened ; with dense punctures of moderate size, 

 longitudinally or obliquely confluent about base, rather larger 

 and sparser between eyes, and smaller and denser on clypeus 

 than elsewhere ; median line feeble or absent. Prothorax
