774 mr. m. jacoby on new [Dec. 16, 



This species may be distinguished from L. bicincta, Lac, and 

 others similarly marked, by the colour of the antennae and the 

 distinct basal depression of the elytra. 



2. Lema nicaraguensis, sp. nov. 



Elongate, parallel. Head and thorax ferruginous ; antennae 

 (base excepted), breast, tibiae, and tarsi black ; elytra bluish black, 

 the lateral margins, a transverse median band, and the apex flavous ; 

 femora and abdomen testaceous. 



Length 3 lines. 



Hab. Chontales, Nicaragua. 



Head not constricted behind the eyes, with a transverse and a 

 median groove at the vertex, entirely impunctate, shining ferruginous, 

 epistome black ; palpi and the two basal joints of the antennae 

 ferruginous, the other joints piceous, the apex of each joint fulvous. 

 Thorax subquadrate, the sides moderately constricted behind the 

 middle ; surface distinctly transversely grooved near the base, with 

 two rows of small punctures placed longitudinally on the disk, rest 

 of the surface smooth, shining ferruginous. Elytra deeply punctate- 

 striate anteriorly, the punctuation gradually diminishing, but remain- 

 ing distinct to the apex, the interspaces near the latter slightly 

 costate ; a rather obsolete transverse depression is placed below the 

 base ; the colour is a dark bluish black, the lateral margins, a trans- 

 verse median band not quite touching the suture, and the apex 

 flavous. Abdomen and the femora testaceous ; breast, tibiae, and 

 tarsi black. 



This species bears a close resemblance to several others described 

 by Lacordaire and Clark, from all of which, however, it differs in the 

 coloration of one or other parts. It is most nearly allied to L. placida, 

 Lac, and L. violaceo-fasciata, Clark. The colour of the femora and 

 of the apex of the elytra distinguishes it from the first species, 

 while it differs from the last by the red head and the colour of the 

 antennae ; it may, however, turn out to be a variety of one or the 

 other. 



3. Lema antennalis, sp. nov. 



Elongate, parallel ; chestnut-coloured, variegated with piceous. 

 Antennae short, the joints transverse, black ; elytra piceous, margined 

 with brown, punctate-striate, intervals finely rugose. 



Length 3 lines. 



Hab. Zapote, Guatemala. 



Head impunctate, lower part of face sparingly fulvous-pubescent ; 

 eyes deeply emarginate : antennae short and robust, only reaching 

 to the base of the elytra ; three basal joints brown, shining ; the rest 

 black, closely pubescent ; first joint swollen, round ; second of the 

 same shape, shorter ; third half as long again as the second ; the 

 following joints gradually widened, transverse, broader than long. 

 Thorax without transverse basal depression, subquadrate, brown, 

 shining, obsoletely streaked with piceous, surface minutely punctured. 

 Elytra deeply punctate-striate anteriorly, the punctuation diminishing
