814 MR. M. JACOBY ON NEW COLEOPTERA. [DeC. 5, 



14. Chalcophyma reticulatum, sp. nov. 



Subquadrate, rounded behind, dark purplish or violet ; head 

 marked exactly in the same way as in C. striata ; antennae flavous ; 

 thorax of the same shape as in the preceding species, deeply and 

 closely punctate, the intervals between the punctures raised and 

 forming a network in a longitudinal direction ; towards the sides are 

 some deeper and larger impressions ; scutellum smooth, shining ; 

 elytra with a number of indistinct elevated costae, between which 

 the space is deeply punctate and rugose. Legs red brown. 



Length 2\ lines. 



Hab. Amazons. 



This species is sufficiently distinguished from C. striata by the 

 reticulate sculpture of the thorax, and the much more numerous 

 costse on the elytra, which are only now and then interrupted, but 

 extend in two or three instances through the entire length of the 

 elytra. 



Genus Typophorus, Erichson. 



15. Typophorus mexicanus, sp. nov. 



Ovate, convex, above violet-blue, beneath black with a green tinge. 

 Head reddish brown, finely and sparingly punctured, with a distinct 

 triangular groove at its lower half, and a deep curved depression 

 above each eye ; jaws dark brown ; antennae more than half the 

 length of the body, with the first three or four joints reddish, the rest 

 black, covered with whitish pubescence. Thorax of the same colour 

 as the head, with the posterior and lateral margin evenly rounded, 

 the anterior widened in the middle, impressed in the same way as the 

 head, with minute punctures only visible under a strong lens ; scutel- 

 lum broader than long, impunctate. Elytra of about double the length 

 of the thorax, with their sides nearly parallel, violet-blue, impressed 

 with ten rows of punctures, which diminish a little in size towards the 

 apex ; below the shoulder is a short transverse depression, usually to 

 be found amongst this genus. Legs and tarsi coloured as the uuder- 

 side. 



Length 2\ lines. 



Collected by Mr. O. Salvin at Guatemala. In my collection. 



16. Typophorus melanocephalus, sp. nov. 



Ovate, moderately convex, metallic green or blue. Head greenish 

 black, strongly and closely punctured ; antennas long and slender, 

 with the fix*s t five or six joints fulvous, the rest dark brown. Thorax 

 red, a little more strongly punctured than in T. mexicanus; otherwise 

 of saixxe shape ; the middle of the anterior margin is marked with a 

 short greenish patch which seems to be a continuation of the colora- 

 tioxx of the head. Elytra very strongly punctate-striate, with the 

 usual transverse depressioxx below the shoulder. Underside and legs 

 black. 



Length 3 lines.
