482 Mr. F. P. Pascoe on Sphserion and Mallocera. 



the tarsi are rather short, with the basal joint of the posterior 

 not longer than the two next together. The type is an insect 

 collected in some abundance in Central America by M. Pilate, 

 who gave it the MS. name of Sphcerion basicorne. What the 

 specific name is in allusion to, I am not aware ; as, however, it 

 is so known in collections, I have not altered it. Stenocorus 

 unicolor, Randal, may be referred to this genus. 



Psyrassa basicornis, 

 P. ferruginea, nitida, dimidio apicah elytrorum nigricante. 

 Hab. Yucatan. 



Ferruginous, shining, with sparsely scattered hairs, rather 

 coarsely punctured above, less so on the head ; scutellum equi- 

 laterally triangular, covered with a close silvery pubescence; 

 elytra with the posterior half blackish, each apex with two short 

 spines; body beneath brownish, the abdomen darker, very 

 glossy ; legs with long stiffish hairs. Length 6 lines. 



LiMOZOTA. 



Antennce muticse ; tuberibus antenniferis approximatis. 

 Prothorax cylindricus, elongatus, lateraliter inermis. 

 Elytra parallela ; apicibus emarginatis, haud spinosis. 



The type of this genus is well known under M. Chevrolat*s 

 name, Mallocera virgata; but from Mallocera it differs in every 

 one of the above diagnostic characters. The head is very short 

 in front, its breadth being considerably increased by the large 

 prominent eyes ; the antennae are twice as long as the body in 

 the male, and without any trace of spines; the prothorax is 

 slender and cylindrical, with three small tubercles on the disk, 

 giving it that "personate" appearance of eyes and nose, and 

 sometimes of mouth, so common in this subfamily; the elytra 

 are narrow, parallel, and rounded at the apices; the legs are 

 somewhat slender, the femora slightly thickened, but not cla- 

 vate; the basal joint of the posterior tarsi slender, and not longer 

 than the two next together. 



Limosota virgata. 

 L. pallide flavescens ; elytris lineis flexuosis brunneis ornatis. 

 Hab. Columbia. 



Pale yellowish or straw-colour ; head and prothorax with a 

 close greyish pubescence mixed with long hairs ; the prothorax 

 with two black, round, shining tubercles on the disk, and an 

 oblong one behind them; scutellum smooth, cordate; elytra 

 with scattered hairs only, irregularly punctured, one principal
