LEMA. 11 



Head convex, impunctate, not constricted behind the eyes ; antennae not quite half the length of the body, the 

 fifth to the eleventh joints thickened and robust ; thorax rather longer than broad, its sides moderately 

 constricted, surface with a few very minute punctures in the middle, the transverse groove obsolete ; 

 scutellum black ; elytra with a distinct semicircular depression below the base, their surface rather depressed 

 and very deeply punctate-striate, the interstices near the apex distinctly costate ; the ninth stria is only indi- 

 cated by one or two punctures anteriorly, the rest is smooth and costate ; the colour of the elytra is of a 

 rather lighter shade than that of the thorax ; each elytron has a small black spot at the shoulder and a 

 short longitudinal rather curved stripe near the apex ; the suture, to the extent of one third its length, 

 is also narrowly black at the base. Below, the sides of the breast, the coxae, and the knees, as well as the 

 tibiae and tarsi, are black ; the other parts light fulvous, finely pubescent. 



Hob. Guatemala, Calderas {Champion). 



I know of no species with which the present one may be confounded ; the circular 

 depression at the base of the elytra and the markings of the latter distinguish it from 

 nearly allied forms of the second subdivision of Lacordaire. 



46. Lema discoidalis. 



Oblong-parallel, flavo-testaceous ; antennae (the first joint excepted), apex of the tibiae, and the tarsi black ; 



elytra foveolate, punctate-striate, flavous, the disk occupied by a broad longitudinal piceous patch from 



base to nearly the apex. 

 Length 2 lines. 



Hob. Guatemala, Zapote {Champion). 



The differences between this insect andZ. dejeani, Lacord., to which it is closely allied 

 in coloration, consist in the following points :— It is smaller and of a uniform testa- 

 ceous colour, while in L. dejeani the anterior part of the head is black ; the principal 

 difference, however, consists in the sculpture of the elytra, the latter in the present insect 

 being so deeply punctate as to represent small foveas ; the interval between the eighth 

 and ninth striae is also much less raised and does not form a distinct costa as in 

 L. dejeani; lastly, the two patches on the elytra of the last-named species are here 

 united and form one continuous broad vitta, whose extremity is widened and does not 

 touch any of the margins; the thoracic transverse impression near the base is much 

 more distinct than in L. dejeani, 



47. Lema hogei. (Tab. II. fig. 5.) 



Oblong, fulvous ; antennae, tibiae, sides of the breast, and a round spot on each elytron below the base black. 



Length 2 lines. 



Head impunctate, with the orbital grooves distinct ; antennae filiform, as long as half the body, black, first and 

 second joints fulvous ; thorax subquadrate, sides moderately constricted, basal groove obsolete on the 

 disk, distinct at the sides, surface smooth, impunctate ; elytra parallel, with a short but deep transverse 

 depression below the base, very deeply punctate-striate, the ninth stria interrupted, interstices near the 

 apex costate, fulvous, with a round black spot placed in the hollow of the basal depression. Underside 

 finely covered with yellowish pubescence ; the sides of the breast, the upperside of the anterior femora, 

 together with the tibiae and tarsi, black ; posterior femora a little shorter than the abdomen.
