608 MR. M. JACOBY ON PHYTOPHAGOUS COLEOPTERA. [NoV. 1 6, 



91. MoNOCESTA SPLENDIDA, Clark. 



Six specimens of this handsome species were collected ; they differ 

 slightly from the type in the metallic blue (not green) colour of the 

 elytra and underside, as well as in the somewhat stronger punctuation 

 of the former parts. 



Genus Chthoneis, Baly. 



92. Chthoneis apicalis, sp. nov. 



Elongate, widened posteriorly. Black ; elytra finely and closely 

 punctured, fulvous, their posterior half dark blue. 



Length 5 lines. 



Head distinctly punctured at the vertex, the latter obscure rufous, 

 deeply transversely grooved between the eyes ; antennae half the 

 length of the body, black ; first and fourth joints of nearly equal 

 length and the longest, second and third joints subequal, the rest 

 subdepressed, widened. Thorax subquadrate, broader than long, 

 the angles thickened ; surface irregularly depressed, closely and 

 rather strongly punctured ; scutellum black, triangular. Elytra 

 widened from base to apex, moderately convex, very closely and 

 rather finely punctured, the interstices slightly wrinkled, the anterior 

 portion to a little below the middle fulvous, the rest dark greenish 

 blue, shining. Abdomen at the sides or entirely testaceous, rest of 

 the underside and the legs black. 



31us. Godman and Salvin, and Jacoby. 



I believe I am riglit in referring the above insect to Mr. Baly's 

 Chthoneis, although the species before nie is larger and more robust 

 and the antennje shorter ; the open anterior coxal cavities, the com- 

 pressed antennae, however, as well as the unarmed tibiae and the 

 long first tarsal joints, agree well with the typical species belonging 

 to Baly's genus.
