210 Mr. H. W. Bates on Geodephagous 



Note on the remaining Ceylonese Species of Geodephaga 

 described hy Walker. 



In addition to the species included in the synonymy of the 

 foregoing there are several described by Walker which were 

 not met with by Mr. Lewis. The following notes made on 

 an examination of the types will be useful. 



Droynius marginifer. 



This is a DolicJioctis closely allied to D. quadriplagiatus ^ 

 which Walker described as a Colpodes. It agrees in size 

 (6 millim.) with the smaller examples of that species, and is 

 almost exactly the same in colours and markings, the chief 

 difference being that the basal spot of the elytra is not oblique 

 but rounded or slightly transverse and placed near the 

 shoulder. In form the insect is narrower than D. quadripla- 

 giatus ; the thorax is rather more quadrate, i. e. less rounded 

 on the sides, hut with similarly distinct subrectangular hind 

 angles. 



Dromius repandens. 



A Tetragonica similar in colour to T. intermedia^ i. e. rusty 

 brown, with disk of elytra paler tawny and sides vaguely 

 fuscous. The thorax, however, differs in outline from that of 

 all the described species, being gradually and rather strongly 

 narrowed behind, with rectangular hind angles. The third 

 elytral interstice has two setiferous punctures, one near the 

 base, the other near the apex. 



Catascopus reductus. 



A very different species from C. reductus, Walker, described 

 by Chaudoir. It is one of the smaller species allied to C. vio- 

 laceus (Schmidt-Gobel) ; the thorax angulated on the sides, 

 the forehead with two strong carinse on each side, and the 

 elytra metallic olive-green, strongly punctate-striate, with the 

 seventh interstice only slightly elevated. 



Scarites designans. 



An Oxylobus with broad and plane elytral interstices. 

 Chaudoir, in his revised ' Monograph ' (1879), refers it to 

 Scarites sculptilis, Westw. ; it is not clear why, as there is 

 nothing in Westwood's description to lead one so to identify 

 the two species. 0. designans is distinct from 0. lateralis^ 

 Be]., to which it is referred in the Munich Catalogue.
