the middle towards the base ; scutellnm small, deeply sunk 

 between the elytra and prothorax; elytra convex, much 

 broader than the prothorax at the base, the apex broadly 

 truncate, a row of coarse punctures by the suture gradually 

 dhninishing posteriorly, otherwise impunctate, a well-marked 

 silaceous line beginning at the shoulder, curved inwards at 

 the middle and again near the apex, and connected with a simi- 

 lar submarginal line — together forming a sort of figure of 8 j 

 body beneath and legs brown, with dispersed scales, anterior 

 and intermediate femora slightly toothed ; the two basal seg- 

 ments of the abdomen of equal length. 



The coloration is somewhat similar to Rhynchcenus pusio 

 (what could have induced Linnseus to give so large a species 

 such a specific name 7) , but the broadly truncate elytra gives 

 it a place in Chevrolat's genus. 



CyjphorJiynchus diurus. 



C. subovatus, fuseus, squamulis flavicantibus adspersus, supra tuber- 

 culatus ; prothorace elytrisque lineis duabus obliquis niveis ad 

 suturam in medio estensia ornatis, apice singidorum producto.

Subovate, brown, with scattered, minute, yellowish scales ; 

 a narrow, white, very distinct stripe from the side of the 

 prothorax, continued obliquely to the elytra, and meeting- 

 its fellow at about the middle of the suture ; rostrum 

 shorter than tlie prothorax, gibbous at its junction with 

 the head ; antennae ferruginous ; prothorax very irregular, 

 suddenly narrowed anteriorly, with two tubercles at the apex 

 and two larger ones behind them ; scutelium rounded • elytra 

 broader than the prothorax, unequally tuberculate, the largest 

 an oblong ridge near the middle and away from the suture, 

 the intervals coarsely punctured, the apex of each diverging 

 into a cylindrical horizontal tubercle ; posterior femora strongly 

 toothed ; tibiae compressed, curved ; tarsi ferruginous. 



Allied to C. rugosus [anf^ ' Annals,' Apr. 1881, p. 304), 

 but smaller, narrower behind, and the elytra apiculate.
