2 horns, and the form and proportions of the 4 basal joints of the antennae are 

 different and do not quite accord even with his generic character ; for he says, 

 " articulo primo brevi, incrassato, sequentibiis tribus brevibus, tenuibus ; cse- 

 teris dilatatis aut perfoliatis :" now the 3rd joint in our insect cannot be called 

 short comparatively, and the 4th is the 1st of the dilated and cup-shaped joints. 



*128. Alphitobius ? punctatus, Curt. 



EUipticus, subconvexus, virescenti niger, punctatissimus, elytris piceo-brunneis 



striato-punctatis, trophis antennis pedibusque castaneis. 

 Length 2 lines, breadth 1. 



Elliptical and slightly convex, black, with an obscure green shade, and scattered over with 

 minute hairs : head and clypeus convex, orbicular, entire and punctured : thorax a little 

 transverse, scarcely narrowed in front, the sides gently convex: elytra brown and 

 punctured, with 8 punctured striae on each, and an abbreviated one next the scutel, 

 which is semiovate : abdomen punctured and striated : legs, trophi and antennae cas- 

 taneous, the latter fuscous at the apex. 



From Valparaiso; I have also received it from other parts of Chili. 



It appears to associate best with Dejean's genus Heterophaga, which never 

 having been characterized, I have adopted Mr. Stephens's name, the type of 

 which is the Tenebrio mauritanica , Fab.
