268 * [November 



This species was collected by Mr. W. J. Howard in Kansas near the 

 Rocky Mountains, and presented to the Society by Mr. Charles Wilt. 

 Three specimens have been examined, in one of which the sides of the 

 thorax have several depressions, and the fourth joint of the antennae is 

 annulated with cinereous, in the others the antennse are entirely black ; on 

 the disk of the elytra several stray punctures are visible here and there, 

 but in all three specimens the punctures are grouped about the humeri 

 and along the angulation of the elytra. 



This species may resemble M. Iscvidorsale White, from Mexico, of which 

 a very short and meagre description is given in the Proceedings of the 

 Zoological Society of London, lb56, p. 407 ; but the punctation of the 

 elytra seems to be differently arranged. 



MONILEMA SUBRUGOSUM n. Sp. 



Shining black; fourth joint of the antennao annulated with cinereous; 

 dorsal surface of the thorax opaque; elytra coarsely punctured, somewhat 

 rugose. 



Ilah. Cape St Lucas, Lower California. 



9 . Body elongate, shining black. Head bright on the front and cheeks, 

 opaque on the top, more closely punctured on the front than on the vertex ; 

 a slight dorsal impressed line not extending down the front. A-ntennae about 

 two-thirds the length of the body, stout, punctured, the punctures on the 

 basal joint deeper and closer, fourth and following joints clothed with very 

 fine, black, silky pubescence, a cinereous annule on the fourth joint. Thorax 

 about as long as broad; disk opaque, sides shining; closely and finely 

 punctured, the punctures larger and more distinct on the sides; a smooth 

 spot on the disk; posterior margin shining, with an uneven row of deep 

 punctures; lateral tubercle obsolete. Scutellum large, broad, rounded and 

 sparsely punctured. Elytra shining black; convex; sides suddenly' de- 

 flexed ; little shorter than the abdomen ; coarsely punctured, the punctures 

 closer and more profound at the base about the humeri and at the angula- 

 tion of the elytra, and more sparse and less deep on the disk, becoming- 

 obsolete on the tip which is covered with wavy lines and with the suture 

 rugose. Last dorsal segment of the abdomen extending beyond the elytra, 

 sparsely and distinctly punctured; ventral segments shining, finely punc- 

 tured, more sparse on the sides, last segment slightly emarginate at tip. 

 Legs stout, densely punctured; tibia? and tarsi clothed with short black 

 hairs; tarsi fulvous beneath. Length 13 lines.
