Prothorax hardly wider than head (1 x 1-35 mm.), widest 

 considerably in front of middle; sides angulate at widest part, 

 lightly obliquely narrowed to apex, obliquely (not roundly) 

 narrowed to base, lightly sinuate before base; apex deeply 

 truncate-emarginate ; anterior angles prominent, obtuse ; base 

 truncate; basal angles rather obtuse. Elytra ovate (4-7 x 2-6 

 mm.), lightly rounded on sides, lightly striate; third interstice 

 with five faint punctiform impressions; base lightly and semi- 

 circularly emarginate behind peduncle. 



Length 7 "2, breadth 2-6 mm.

This species is very closely allied to ff. parvicoHis, Blkb., of 

 which it seems the western representative; but is a little smaller, 

 with narrower elytra less rounded on the sides. II. parvicollis 

 and H. vicinus seem to be separated from the other described 

 species of Homothes by the shape of the prothorax (but I do not 

 know^. elegans,~i^e\\VLi., and H. sericeus, Er.). All the other species 

 known to me have the sides of the prothorax rounded behind the 

 marginal seta and with a strong sharp sinuosity near the base 

 which results in the prothorax having a basal lobe; in H. 

 parvicollis and H. vicin^is the sides are obliquely narrowed to the 

 base, and the sinuosity before the base is so wide that the base is 

 in no way lobate in the middle.

 side behind eyes; prothorax subcordate, wider across apex than
