168 MR. M. JACOBY ON NEW [Mar. 2, 



5. Lamprosoma guatemalense, sp. nov. 



Obloug-ovate, narrowed behind, convex. Black; above violaceous 

 blue ; head, sides, and anterior margin of thorax and a broad band 

 at the extremity of the elytra cupreo-aureous. 



Length 1| line, 



Hab, Zapote, Guatemala. 



Head obsoletely impressed in the middle, not closely, but distinctly 

 punctate ; labrum black. Sides of the thorax greatly deflexed, the 

 lateral margins slightly rounded, anterior angles very acute ; surface 

 closely punctured, but not more deeply than the head ; the sides and 

 anterior margins are occupied by a broad cupreo-aureous band, leaving* 

 only the middle of the base and a protruding point at the middle of 

 the ground-colour. Elytra regularly convex and narrowed behind, 

 rather deeply punctate-striate, dark violaceous blue ; a broad band 

 of the same colour as that of the thorax is placed at the last 

 third near the lateral margin, and extends across the suture to the 

 other side, covering at the same time the extremity of the elytra. 

 Underside and legs black. 



This species is closely allied to L. schitiUans, Lac, and others de- 

 scribed by the same author, from all of which it differs, however, in 

 the shape of the band of the thorax as well as that of the elytra 

 and the distinct punctation of the head.

6. Lamprosoma politum, sp. nov. 



Oblong-ovate, convex, narrowed behind. Metallic green; tarsi 

 and antennae (the second and third joints of the latter excepted) 

 black ; head distinctly, thorax minutely, punctate ; elytra narrowed 

 behind, with ten rows of deep punctures, the interstices minutely 

 punctate. 



Length 2| lines. 



Hab. Brit. Honduras (Blancaneau). 



Head slightly convex, very distinctly punctured ; eyes broadly 

 emarginate ; labrum black. Thorax transversely convex, its sides 

 straight ; the anterior margin not produced in the middle, regularly 

 concave at each side ; posteriorly acutely ])roduced in the middle, the 

 sides regularly crescent-shaped ; surface scarcely punctured. Scutel- 

 lum black. Elytra regularly convex, slightly narrowed posteriorly, 

 the lateral lobes acutely, but moderately, produced; each elytron with 

 ten rows of very deep punctures, the last two outer rows of which 

 are much closer approached than the others ; the interstices also 

 finely punctate. Prosteruum slightly longer than broad, distinctly, 

 but not closely, punctured. 



This species resembles much L. speciosum, Lac, from Brazil ; but 

 it is narrower, less convex ; the thorax is much finer punctured, and 

 the interstices of the strice on the elytra are also minutely punc- 

 tate ; and as the locality is also far removed, it is no doubt a good 

 species.
