96 PHYTOPHAGA. 



almost cylindrical, their surface very obsoletely punctate-striate, with the. exception of the last row of 

 punctures, which is distinct near the apex, the colour is a dark violaceous blue, and the apex is occupied 

 by a broad aureous spot, which extends laterally to nearly half the length of the elytra ; underside and 

 legs shining black ; prosternum longer than broad, slightly hollowed out along its surface, and with a 

 few punctures. 



Hab. Mexico, Yolotepec (Boucard, coll. Salle). 



The coloration of this species is again nearly identical with several others belonging 

 to this division, from all of which it differs, however, in its small size and narrow 

 elongate shape, as well as in the almost obsolete punctuation of the elytra. Only a 

 single specimen is before me. 



17. Lamprosoma ignicolle. 



Lamprosoma ignicolle, Jacoby, P. Z. S. 1880, p. 167. 



Hab. Beitish Hondukas, river Sarstoon (Blancaneaux). 



This species may be recognized from all the preceding ones, with each of which it has 

 one or other characteristic mark in common, by the entirely bright reddish golden 

 colour of the thorax, in which respect it resembles L. refulgens ; but this species is much 

 smaller, and the underside and legs are black, while here they are bright metallic aureous. 

 The species was described by me from a single specimen ; and although distinct in regard 

 to its colour from any other, it may yet be but a variety of one or the other allied forms. 



18. Lamprosoma guatemalense. 



Lamprosoma guatemalense, Jacoby, P. Z. S. 1880, p. 168. 

 Hab. Guatemala, Zapote {Champion). 



Again extremely closely allied to L. refulgens, L. ignicolle, and others, from which 

 it may be recognized by its small size, and especially by the narrowness of the elytra at 

 their apex, which is almost pointed. The thorax of this species is very closely punc- 

 tured, and has a violaceous spot at the base, which interrupts the golden colour in its 

 centre, the coloration being exactly like that of L. cupricolle, Lacord., from Colombia. 

 That species, however, has, according to its describer, a smooth thorax and obsoletely 

 punctured elytra, which in the present insect are very distinctly punctate. 



b. Species unicolorous above. 



19. Lamprosoma semiopacum. 



Lamprosoma semiopacum, Lacord. Mon. p. 593 l . 

 Hab. Yucatan, Merida 1 . 



The opaque head and thorax forms the principal distinguishing character of this 

 species ; the type in the collection of Mr. Baly is before me, and agrees perfectly with 

 Lacordaire's description.
