This insect is closely allied to Baconi, but it differs as 

 follows : — It is smaller, with the inner thoracic stria com- 

 plete and without a fovea, the fourth elytral stria short and 

 formed only of punctures, and the sixth faint and visible 

 only before the apex. I compared this with the type of 

 Baconi in Marseul's collection when last in Paris.

The system of surface-sculpture here places the species in 

 the abyssinicus group. The diminutive size, more depressed 

 form, non-sinuate mesosternum, and smooth pygidium are its 

 most distinctive characters. 



Hister decollatus and glabratus, Roth, are allied to abys- 

 sinicus and subsulcatus, but cannot be identified by the de- 

 scriptions published in 1851. 



Hister regularis, Leconte, also is of the same section, and 

 the name would probably prove to be a synonym could the 

 type be examined. The locality given by Leconte is "Africa," 

 and species of the abyssinicus group occur on both the east 

 and west coasts. 



Hister metallicus, n. sp. 



Oblongus, convexus, seneus, nitidus ; fronte subbifoveolata, stria 

 integra, antice elevata, subtiliter punctulata ; pronoto larvi, stria 

 interna integra, externa vix abbreviata ; elytris striis 1-3 inte- 

 gris, et cseteris obsoletis ; propygidio (utrinque bifoveolato) pygi- 

 dioque grosse punctatis, in medio lsevibus, prosterno basi depresso, 

 mesosterno stria integra. L. 8 mill. 



Hab. India ; two examples in the British Museum, and 

 one in my own collection. 



This species must be placed next to punctulat us, and it is a 

 very remarkable species on account of its colour. It differs 

 chiefly from yunctulatus in the absence of punctures on the 

 head, thorax, and elytra, and in the forehead being more 

 transverse.
