C'ni.-i:xiiis. 



C pniiotuIafuN. 



One elytron of tlie size and very similar to that of C. httirolUn, from 

 which it differs in having; the stri;« n)ore finely impressed and the 

 jumctures rather closer, while those of the intervals are co:irser and 

 less numerous. Lenj^th .40 inch ; 10 mm. 



There can be no doubt that the generic determination is correct in 

 this instance. 



DICVELLS. 

 I>. alutaceus. 



Two elytra much flattened, retaining their proper position in relation 

 to each other, remain, with but little of their actual substance, enough 

 however to indicate the surface sculpture. 



A species is indicated bearing a close relationship to (Jilafafnit, but 

 with the intervals somewhat more convex and the surfjvce n)ore dis- 

 tinctly alutaceous. The humeral carina appears to have been ex- 

 tremely fine and rather less elevated than in iJllatdtiix. 



Eljjtra. — Length .70 inch; 17.5 mm. Width .40 inch; 10 mm. 



The measurement includes also the portion of the elytra covered by 

 the base of the thorax. AVith proper allowance being made f:)r flatten- 

 ing a species is indicated of as large size as our largest inu-purdtus but 

 relatively nari'ower. 



I>. sp. 



Another species of much smaller size than the preceding, is indi- 

 cated by an impression of the greater part of both elytra and a very 

 small fragment of one elytron, resembling D. clomjatni^. The carina 

 ajtpears to be of similar length and the intervals moderately convex, 

 e(|ual and smooth. 



No measurements can be given as I have not sufficient material on 

 which to base them, and I must also leave the species nameless.

C? cbciiiiiiiin. 



The remains for which the above name is suggested, consist of the 

 greater portion of the thorax, the two elytra in a fair state of preserva- 

 tion and a portion of the abdominal segments. These may be described 

 as follows : 



Thorax nearly twice as wide as long, sides feebly arcuate, gradually 

 converging anteriorly, surface sparsely and finely punctate, pleur;x3 

 longitudinally finely strigose. Elytra rather wider, conjointly, than 

 long, sides moderately arcuate and gradually narrowed to apex, disc
