 Episomus dathnitus, Boheman,* op. cit. p. 89 [S)- 



Colour dull black, with light brown scaling in the fovese only ; 

 usually with a small spot of pale scales at the apex of interval 5. 



Head with the central furrow very broad and deep, ou each side 

 of it a short backward indentation from the transverse ante-ocular 

 furrow. Rostrum about as long as broad, slightly dilated near the 

 apex, the central furrow either parallel-sided or with a rounded 

 dilatation in front, the lateral costa bearing a deep curved im- 

 pression. Antenna- with comparatively thin scaling, which is 

 denser and paler on the underside of the scape ; the funicle with 

 joint 2 slightly longer than 1, and 3 than 4, 7 conical and a trifle 

 shorter than the club. Prothorax a little broader than long, the 

 sides slightly rounded in the 6 and scarcely so in the 5 , the base 

 bisinuate and somewhat broader than the apex, the central furrow 

 and the lateral plications deep. ScuteUum small, sometimes 

 scarcely perceptible in cS . Elytra elongate-ovate in $ , much 

 narrower in S , the humeral angle obtuse, the dorsal outline not 

 very convex, beginniujo; to slope gradually behind the middle, the 

 steep posterior declivity sloping somewhat inwards and slightly 

 indented ; the shallow sulci contain large subquadrate fovece, the 

 intervals narrow but not carinate, the suture sharply raised at the 

 top of the declivity and more prominent in $ . Legs with pale 

 scaling, which is very sparse above and dense beneath, the liind 

 tibiae of the cJ not granulate internally and w ithout any apical 

 spur. 



Length. 11-16 mm.; breadth, 4|-7 mm.

Ti/2)e not traced ; that of E. dathratus in the Stockholm Museum. 



I have seen a single $ from the Nilgiris in which the prothorax 

 appears much smoother, the deep plications being replaced by 

 much finer superficial rugosities, while the central furrow has 

 disappeared, being represented only by a rounded impression 

 at the base. As in other respects it resembles E. montanus, 

 I provisionally treat it as a variety under the name of levicoUis, 

 var. nov. 



178. Episomus arcuatus, sp. nov. (fig. 60, /). 



Very closely allied to E. montanus. Guer., and differing only in 

 the following respects : — 



Antennce with joint 2 of the funicle not longer than 1, and 3 

 equal to 4, the club distinctly stouter. Prothorax with the median 

 carime much less raised and broken up into a number of irregular 

 sinuosities. Elytra distinctly more elongate, the shoulders more
