Plaiypodidce and Scolytidce. 113 



consisting of rows of double lunate plates facing each other 

 transversely but separated, the intervening space furnished 

 with a single hair bent towards the apex of the elytra ; the 

 interstices transversely rugose and sparsely hairy, the de- 

 clivity commencing at the apical third, with a fundus formed 

 by the outward deflexion of the first interstice, the continued 

 narrowing of the second until the subsequent fusion of the 

 first and third, leaving a flat, dull, irregularly punctured 

 surface to the apex ; interstices 1 and 3 become strongly 

 toothed at the commencement of the declivity, and 5 and 7 

 have smaller teeth closer to the apex ; the basal edge of the 

 elytra is raised and strongly toothed. 



Long. 3-3*5 mm. 



Hab. India. 



? . Differs from the male in the slightly convex front 

 and stronger longitudinal rugosity, and in the rather shal- 

 lower and narrower fundus, as well as in the smaller inter- 

 stitial teeth. Immature specimens are very pale in colour, 

 but the prothorax eventually becomes black and shining, 

 and the elytra a dark brown. 



Long. 3 # 5 mm. 



If the single specimen in my collection of P. cristatus, 

 Lee, is correctly named, the present species is very nearly 

 allied to it, but in the former the interstices are straight, the 

 first and second become obsolete at the declivity, and the 

 third only has large black tubercles. 



Genus Cryphalus, Er. 



The new species of Cryphalus is determined from a series 

 of specimens in the collection of Mr. H. E. Andre wes : — 



Cryphalus corpulentus, sp. n. 



<J . Subovafce, brown. Front slightly concave and punc- 

 tate, longitudinally aciculate at the vertex. Prothorax 

 transverse, sharply narrowed apically, with 4-6 frontal 

 tubercles, above which are two central ones and three con- 

 centric transverse elevations, the last being on the vertex 

 of the prothoracic gibbosity. Elytra lineate-punctate, the 

 striae faintly impressed and furnished with small irregularly 

 placed scales, the interstices nearly flat with large erect 

 scales of a pale colour and placed at considerable intervals 

 apart. 



Long. 1'4-1'5 mm. 



Hab. India, Nilgiri Hills.
