80 ZOOLOGICAL. COLLECTIONS MADE DURING [Jan. 4, 



VII. COLEOPTERA. 



By Chas. O. Waterhouse. 



Carabid^. 



1. Carabus suTURALis, Fabr. Syst. El. i. p. 238. 



Four specimens ft-om Neesham Cove, Cockle Cove, Elizabeth 

 Island, and Svcallow Bay. 



2. Brachyccelia concolor, sp. n. 



Cyaneo-nigra , subtus nigra, IcEvis, nitida ; antcnnis pedibusque 

 jnceonigris ; elytris striatis, striisfere IcEvibus. Long. 8| mill., 

 lat. 4 mill. 



Very close to B. virescens, G. R. Waterb., but smaller, darker in 

 colour, and with the antennse and legs nearly black. Thorax 

 nearly of the same form, transverse, gently arcuate at the sides, but 

 with the posterior angles very slightly turned outwards and slightly 

 acute. The elytra are a little more ovate ; i. e. the broadest part is 

 rather further from the apex than in B. virescens ; each elytron has 

 nine striae, the five dorsal ones moderately strongly impressed and ex- 

 tending nearly to the apex, with no proper punctuation, the interstices 

 slightly convex, especially the fifth ; the sixth and seventh striae are 

 less distinct, and the eighth is only visible posteriorly ; the ninth is 

 very distinct and has a series of distinct punctures. The prosteruum 

 has a well-marked lanceolate impression between the coxae, very similar 

 to that in B. virescens. The median impressed line on the thorax 

 is shorter than in the specimens of J3. virescens, rather broader in 

 front, and terminating rather abruptly some way from the anterior 

 margin. The anterior and intermediate tarsi are dilated in the same 

 way as in B. virescens. 



A single male example taken at Puerto Bueno. 



3. Cascellius GRAVESii, Curtis, Traus Linn, Soc. xviii. p. 183, 

 pi. 15. f. B. 



Cascellius nitidus, G. R. Waterh. Ann. & Mag. N. Hist. vi. 

 1841, p. 2.55. 



A careful examination of the type specimens of Cascellius gravesii, 

 Curtis, and C. nitidus, Waterh., has convinced me that they are 

 varieties of the same species. The striae of the elytra vary very 

 much, being sometimes almost effaced, and sometimes broken up 

 into well-marked elongate impressions. It was this last form which 

 my father considered the true C. gravesii, and from which he sepa- 

 rated C. nitidus as distinct. The type specimen of C. gravesii, how- 

 ever, has the striae lightly impressed. The series of specimens in 

 the British Museum show the intermediate forms. 



Dr. Coppinger took a single specimen at Puerto Bueno*. 



' It may be well to note here that Cascellius kingii, Curtis, I. c. p. 183, 

 pi. XV. f . A (omitted from Gemminger and v. Harold's Catalogue of Coleoptera), ' 

 is the same as Feronia {Creobius) eydouxii, Gu6rin, Mag. Zool. 1838, p. 4, 

 t. 225. f. 2. Hope's paper was read on May 1st, 1838.
