gradually narrowing to the base. Elytra abbreviated, hollowed 

 out along the sutural margin ; the wings not extending to the 

 last abdominal segment. Legs unequal; anterior and inter- 

 mediate pair very short; posterior much longer, their tibiae linear 

 and twice the length of the anterior ; tarsi very short, all of 

 nearly equal length. Anterior coxae conical, contiguous. Ab- 

 domen depressed, its segments nearly equal in length. 



This remarkable insect has been for years in my collection ; 

 but, notwithstanding its imperfect condition, I am desirous that 

 it shall find its place in M. Lacordaire's work. It is evidently 

 allied to Psebium and Chorotliyse^ especially to the former, but 

 in the form of the head is different from either. 



Nephithea necydaloides. 



N. cyanea, elytris griseis; antennis, scapo excepto, pedibusque 

 nigrescentibus. 



Hab. Natal. 



Dark blue, tinted with violet, the abdomen especially with 

 short stiffish grey hairs; head and prothorax closely punctured; 

 scutellum triangular, black ; elytra pale grey at the base, darker 

 posteriorly, scarcely extending to the end of the second abdo- 

 minal segment, finely punctured, each with two slightly raised 

 lines; body beneath violet, with a thin greyish pile; antennae 

 and legs blackish, the femora with a bluish tint. Length 

 4J lines. 



Demomisis. 



Oculi integri, rotundati, laterales. 



Antennce breviusculae, scapo vix elongato, clavato ; art. tertio sequen- 



tibus (quarto excepto) baud longiore. 

 Elytra linearia, normaha. 

 Coxce anticae exsertae, globosae, approximatae. 



Head nearly quadrate in front, not prolonged into a muzzle. 

 Eyes entire, rounded, placed at the sides beneath the insertion 

 ot the antennae. Antennae rather short ; the scape clavate, not 

 extending beyond the middle of the prothorax ; the third and 

 following joints shorter and more or less of nearly equal length, 

 the fourth being the shortest. Prothorax narrower than the 

 head, elongate, constricted before the middle. Elytra very 

 narrow, linear. Feet rather short; femora fusiform; tibiae 

 slender, straight ; tarsi with the first joint scarcely so long as 

 the rest together. Anterior coxae large, exsertcd, nearly globose, 

 approximate. Pro- and mesosterna very narrow. 



This is a very remarkable form, allied to Rhagiomorpha, from 

 which it is at once differentiated by its entire eyes, — and more 

 remotely to Psilomorpha and Sylliius, but with antennae essen-
