10. Lamprosoma chrysonotum. 



Lamprosoma chrysonotum, Lacord. Mon. p. 579 \ 

 Eab. Mexico 1 , Cordova (SallS), Jalapa (Edge). 



The thorax in this species is entirely impunctate, the elytra have a golden spot 

 below the scutellum, and their lateral similarly coloured band is abbreviated anteriorly 

 below the shoulders. 



11. Lamprosoma panamense. 



Oblong, narrowed behind, convex, black ; head, lateral margin of the thorax, and the apex of the elytra 

 reddish cupreous ; prosternum quadrate. 



Length 2 lines. 



Head finely granulate, distinctly punctured, with an oblong median depression between the eyes ; epistome 

 separated from the face by a distinct transverse groove, its anterior margin almost straight ; jaws and 

 antennae black ; thorax more than twice as broad as long, its posterior lobe moderately rounded, upper 

 surface a little more distinctly punctured than the head, especially near the base, the metallic colour, like 

 that of the head, extending broadly at the lateral, more narrowly along the anterior margin, but varying 

 in prominence when seen in different positions ; scutellum black ; elytra greatly narrowed towards the 

 apex, regularly convex, finely punctate-striate, black, the apex and part of the lateral margin cupreous ; 

 underside and legs black ; prosternum very nearly square-shaped, rugose-punctate. 



Eab. Panama (Boucard). 



The colour of the upper parts and the posteriorly narrowed shape of the present 

 insect will separate it from any other; and although I possess only one specimen, 

 there is no doubt that it is distinct from any described species, not only in coloration, 

 but in the many other ways described above. 



12. Lamprosoma insigne. (Tab. v. fig. 18.) 



Lamprosoma insigne, Lacord. Mon. p. 576 \ 

 Hob. Mexico 1 , Cuernavaca (Salle), Jalapa (Edge). 



All the specimens before me have the anterior elytra! golden band divided into two 

 spots. The shape of this species is broadly ovate. 



13. Lamprosoma opulentum. (Tab. V. fig. 23.) 



Lamprosoma opulentum, Lacord. Mon. p. 577 1 . 

 Eab. California 1 . — Mexico, Juquila (Boucard, coll. SallS). 



This and the preceding species are very closely allied in regard to colour, and also 

 rather variable in this respect. The present species is more elongate, narrower the 

 prosternum longer than in L. insigne, and the colour of the head and the legs metallic 

 green, the same parts in the other species being of a more golden or reddish tint. The 

 specimen figured is from Juquila.
