28 APOGONIA ABDOMINALIS. 



and is situated on the outer boundery line of the third 

 costa. 



The sides of the metaster num are very closely punctured, 

 the punctuation on the abdomen is strong but not dense 

 and agrees with that of the propygidium ; on the pygi- 

 dium, which in two of my three specimens is impressed 

 along the middle, the punctuation is somewhat finer. 



The anterior tibiae are tridentate.

Apogonia pygidialis , n. sp. 



This species has a flat or slightly convex pygidium 

 which is either impunctate or provided with a few very 

 fine hair-bearing punctures. 



Its length varies from 8 to 9 mm. and its colour passes 

 from pale ferruginous brown (immature specimens) to pit- 

 chy black; the under surface, pygidium and femora (es- 

 pecially the latter) remain however of a brighter colour; 

 the palpi and antennae are yellowish ferruginous. 



The clypeus is broad, and rather coarsely punctured; 

 it is broadly but not deeply emarginate in front with the 

 lateral angles of the emargination rounded , the sides are 

 strongly converging in straight lines. On the face , which 

 is separated from the clypeus by a suture , the punctua- 

 tion is somewhat finer and more widely spread. 



The prothorax is obliquely narrowed in front and broad- 

 est behind the middle; the anterior angles are distinctly 

 prominent and somewhat flattened or depressed , the poste- 

 rior ones are broadly rounded, almost without perceptible 

 angle; the punctures ou the pronotum are rather fine, 

 not densely set, and equally spread over the whole sur- 

 face; no basal impressions in front of the lateral angles 

 of the scutellum. The scutellum is broadly triangular with 

 curvilinear sides, smooth, provided with a few fine punctures. 



The elytra have the punctures stronger than those on
