LEMA. 5' 



16. Lema biornata, sp. n. 



Ovate, convex; head, antennae (last three joints excepted), breast, and tibiae black; thorax, abdomen, and 

 femora fulvous ; elytra bluish black, a small spot at the base of each elytron, a transverse band in the 

 middle, and another oblique spot near the apex flavous. 



Length 3 lines. 



Head impunctate, entirely black ; antennae reaching to one third of the elytra, black, their three apical joints 

 fulvous ; thorax nearly as long as broad, the sides not deeply constricted, surface impunctate ; elytra 

 deeply punctate-striate near the base, the punctures greatly diminishing below the latter, almost obsolete 

 towards the apex, the interstices scarcely costate. 



Hab. Guatemala, Senanhu, Vera Paz [Champion). 



This is another species closely allied to L. bitceniata, Lacord., and L. transversa- 

 fasciata, Jacoby, as well as to L.flavofasciata, Clark ; from each of which it differs in 

 some way or other. 



From L. transversofasciata (described here) it differs in the black apex of the elytra and 

 the colour of the antennae and legs as well as that of the breast ; from L. bitwniata in 

 the black head and the small flavous spot near the base of the elytra ; and, lastly, the 

 colour of the underside and head distinguish it from L. flavofasciata. All these species, 

 together with others belonging to the seventeenth group of Lacordaire, are closely 

 allied in coloration; but although the differences between them are not great and 

 consist principally of colour, yet they are constant and form good characters to distin- 

 guish the species from each other. 



17. Lema picturata. 



Lema picturata, Lacord. Mon. *p. 406. 



Hab. Mexico. 



Another nearly allied species to the four or five preceding ones ; the colour of the 

 antennae, which are black, with the exception of the first four joints, will help to 

 distinguish it.
