Choleva marginalis^ sp. n. 



Oval, not narrow, moderately convex, sliglitly nitid ; 

 fuscous, the legs, tiie a])ieal and two or three basal joints of 

 the antenna3 nearly chestnut-red, the front and middle tarsi 

 paler ; ])ubcscenee dense, very slender, cinereous ; on the 

 elytra there are some short erect setce. 



Thorax transverse, much curvedly narrowed anteriorly ; 

 base and apex subtruncate ; the posterior angles just per- 

 ce])tibly overlapping the shoulders, its surface very finely 

 sculptured. Scufellmn distinct, broadly triangular. Elytra 

 gradually attenuated jwsteriorly, apices subtruncate, exposing 

 the pygidium ; with well-n)arked sutural strias and close 

 transversely strigose sculpture ; the lateral margins arc well 

 developed from the shoulders to the hind thighs. Antenna 

 stout, pubescent, the basal three joints equally elongate; 

 fourth and fifth a little shorter and rather stouter ; sixth 

 rather longer than broad, not quite so broad as the seventh ; 

 eighth transverse, not very small, not much narrower than 

 the contiguous ones; tenth a little smaller than the preceding 

 one. 



(^ . Legs stout, femora thick ; t\\c front tihia^wlth a distinct 

 spine at the inner extremity and a smaller one at the outside; 

 the intermediate strongly curvate, with a distinct s]»ine at the 

 iinier apex, a smaller one outside, and two or three finer ones 

 higher up; the ])osterior with elongate terminal spines, and 

 eight or len much finer ones along the outer edge. Anterior 

 tarsi with the basal three joints strongly dilated. 



Underside shining, chestnut-brown, finely clothed, the 

 middle of the metasternum obtusely raised. 



The nearest species arc (\ (ugubritt, Sharp, and C. fuJci- 

 tarsis. From the former it dilfers by the shorter and broader 

 form and by the presence of slender spines on the hind tibiie; 

 from the latter it may be distinguished by the more slender 

 and less evidently j)ubescent middle tibiie, shorter scutellum, 

 less opaque surface, and by the more expanded elytra!
