malleated, but nevertheless nearly un constricted in front, 

 for its legs being a good deal thickened, and for its body 

 being of a piceous hue, with the exception of the elytra 

 which are conspicuously paler, or of a clear rufo-testaceous. 



45. HIMATIUM (nov. gen.}. In its narrow, parallel, 

 cylindric, but not very convex, body which is of a rufo- 

 piceous hue, and sparingly studded with elongate, partially- 

 erect, fulvescent hairs the interesting little Cossonid for 

 which the present genus is proposed, and which has been 

 communicated by Mr. Fry as having been received from 

 Malabar in southern India, will be easily recognized. Its 

 surface is slightly shining, and (with the exception of the 

 head, which is convex and almost free from punctation) 

 coarsely and very densely sculptured; its rostrum is 

 parallel, but nevertheless somewhat narrow and not very 

 elongate ; its eyes are depressed, and greatly separated 

 from each other, so much so indeed that they are barely 

 visible when the insect is viewed from above ; its antennae 

 (which are inserted just before the middle of the rostrum) 

 have their scape rather abbreviated, straight, and robust, 

 and their funiculus-joints (with the exception of the first 

 one), short, subequal, and submoniliform ; its pro thorax is 

 oval, and a good deal constricted in front ; its metasternum 

 is elongate ; its coxse (even the anterior pair) are wide 

 apart, and the third articulation of its feet is nearly 

 simple. 



46. PHOLIDONOTUS (nov. gen.). I am indebted to 

 Mr. Pascoe for the loan of the somewhat obscure and in- 

 significant little insect (captured by Mr. Wallace at 

 Sarawak, in Borneo) to contain which the present genus is 

 proposed ; and, apart from its rather diminutive size, and 

 piceous, opake, densely-sculptured surface, it is remark- 

 able amongst the Cossonidce for being one of the very 

 few forms the surface of which is clothed (as in Pholido- 

 forus from Japan) with scales, some of them being coarse 

 and mud-like, and others thick, robust, and setiform. In 

 the inferior position of its depressed eyes (which are 

 scarcely visible when the specimen is viewed from above), 

 as well as in the structure of its rather long and narrow, 

 but straightened, rostrum, and in the fact of its surface 

 being piceous and (at any rate) clothed, I think there can 

 be little doubt that it displays a certain degree of affinity 

 with the Indian genus Himatium ; but, in addition to its
