admitted, belongs to the family Derodontidse, and must be 

 removed from the group. On the other hand, the following 

 genera, as I have earlier shown in this paper, must be 

 admitted into the group, viz., Torsos 'enus, Spin., Tarso- 

 stenodes, Blckb., and Thanasimorpha, Blckb. 



Necrobioides, gen. nov. 



Head short ; anteclypeus membranous, labrum short, broad, 

 arcuately emarginate in front; eyes finely facetted, emar- 

 ginate in front ; gula very narrow behind. Antennas inserted 

 under a carina opposite the emargination of the eye, eleven- 

 jointed, the last three joints forming a somewhat compact 

 club, 8th joint very short, but nearly as broad as the base of 

 the 9th ; 3rd to 7th joints short, subequal in length. Pro- 

 thorax distinctly margin ate at each side, marked above with 

 a faint sinuately transverse depression at about one-fourth 

 of its length from the apex. Elytra as in Necrobia, but 

 having each a slight swelling on the disc near the base. 

 Acetabula of front coxse open behind. First joint of tarsi 

 placed below the base of the second ; fourth joint very small ; 

 claws bifid, the inner tooth shorter than the outer. 



This genus is formed for a Mexican species, which in 

 colour and form as well as in many points of structure very 

 closely resembles the genus Necrobia. It differs, however, in 

 the structure of its claws, the anterior depression on the 

 the pronotum, and its very much smaller gular area. 



Necrobioides mexicana, sp. n. 



In colour and shape quite like some of the larger blue 

 specimens of Necrobia rvfipes, but with the legs and antennae 

 entirely black. Head thickly but not strongly punctured in 

 front. Prothorax sparsely and feebly punctate. Elytra 

 distinctly and very thickly punctured. 



Length 6, breadth 2^ mm. 



Hab. Mexico : Hacienda de la Imagen in Guerrero, 

 4000 ft. (H. H. Smith). 



One specimen only in the British Museum. This speci- 

 men was sent amongst the Necrobia to Herr Schenkling, 

 and was returned by him labelled Necrobia n. sp. ; but 

 although so very like a Necrobia, I consider that the 

 difference in the structure of the claws, the size and shape of 

 the gula, the presence of a depression anteriorly on the 

 pronotum, and of a hump at the base of the elytra, justify 

 me in regarding it as the type of a new genus.
