LAMPBOSOMA. 95 



14. Lamprosoma refulgens. (Tab. v. fig. 22.) 



Lamprosoma refulgens > Lacord. Mon. p. 582 \ 



Hob. Mexico 1 , Playa Vicente, Cordova (SalU, Hoge); Guatemala, Teleman 

 (Champion). 



The black underside and the elytral aureous stripe, which extends from the shoulder 

 to the apex, distinguishes this species from its allies. Two specimens in M. Salle's 

 collection vary in being shorter and rather more strongly punctured at the elytra, 

 while two others have the aureous colour of the thorax interrupted by a rhomboidal 

 violet spot ; but as neither of these varieties differs in other respects from Lacordaire's 

 description, it would not be prudent to consider them different species. A single 

 specimen received from Guatemala differs again in the shape of the elytral golden 

 band, which here only occupies the apex, and does not extend to the shoulder ; the 

 prosternum is also nearly square. In the absence of more material I am unable to 

 come to a definite conclusion as to the specific value of this Guatemalan specimen. 



15. Lamprosoma bifasciatum. (Tab. v. fig. 19.) 



Ovate, convex, metallic green; thorax finely punctured, with two violaceous longitudinal bands; elytra 

 distinctly punctate-striate, the suture and a longitudinal band at the disk of each elytron, abbreviated 

 behind, violaceous ; abdomen black. 



Length 2 lines. 



Head with a deep longitudinal groove between the eyes, rather closely and somewhat rugose punctate ; anterior 

 margin of the epistome concave ; antennae black, the first joint fulvous below ; thorax closely and distinctly 

 punctured at the disk, more finely at the sides, coloured like the head, with two broad slightly curved 

 violaceous bands from base to apex ; elytra rather deeply punctate-striate, metallic green or aureous, the 

 suture narrowly, and a broad band extending from the shoulder to behind the middle of each elytron, 

 violaceous or purplish ; tarsi and abdomen black ; prosternum nearly square-shaped, finely punctate. 



Hob. Mexico, Tehuantepec, Cuernavaca (Salle). 



This species varies in the width of the violaceous bands and the colour of the under- 

 side, which is sometimes entirely black. The shape of the insect is exactly that of 

 L. insigne ; and I have great doubt whether it is not only a variety of that species ; but 

 as the specimens before me agree in the shape of their pattern, I must regard them 

 as distinct ; moreover the sculpture of the head differs from that of L. insigne in having 

 a deep longitudinal groove. The specimen figured is from Tehuantepec. 



16. Lamprosoma elongatum. 



Oblong-ovate, convex, black; head and thorax aureous, the latter with a transverse basal violaceous spot, 

 closely punctured ; elytra obsoletely punctate-striate, violaceous, the apex cupreous. 



Length 1| line. 



Head convex, with a triangular fovea between the eyes, the surface extremely finely granulate and punctured j 

 anterior margin of the epistome straight; mouth and jaws black; antennae with the first joint cupreous; 

 thorax closely and much more distinctly punctured than the head, of the same colour as the latter, the 

 base occupied by a narrow transverse blue band, which is widest at the middle ; elytra narrow, elongate,
