and Species of Hispidce. 377 



Genus Downesia, Baly. 

 (Sp. 2.) Downesia atrata. 



Filiformis, subcylindrica, nigra^ nitida ; thorace latitu- 

 dine paullo longiori^ modice transversim convexo, sparse 

 sed distincte punctato ; elytris profunde punctato-striatis, 

 utrisque tricostatis. 



Long. 3 J lin. 



Hah. — India; collected by Mr. Brettingham. 



Antennae scarcely longer than the head and thorax, 

 slightly increasing in thickness towards the apex. Thorax 

 narrowly margined, sides straight and parallel, obliquely 

 narrowed at their extreme apex, apical margin slightly 

 produced. Elytra scarcely broader than the thorax ; 

 sides straight and parallel, their apex regularly rounded ; 

 upper surface of each with three strongly raised lon- 

 gitudinal costae, the sutural and lateral borders also 

 costate, interspaces each with a double row of large 

 deeply-impressed punctures ; on the middle portion of the 

 outer, the anterior four-fifths of the inner, and on the 

 extreme base of the middle interspaces, the double rows 

 of punctures become single. 



(Sp. 3.) JDownesia tarsata. 



Filiformis, subcylindrica, flava, nitida; antennis, oculis 

 tarsisque nigris ; thorace latitudine paullo longiore, 

 tenuiter punctato, modice transversim convexo; elytris 

 sat profunde punctato-striatis, utrisque tricostatis. 



Long. 3 lin. 



Hah. — Hong Kong. 



Thorax slightly longer than in the preceding, sides 

 straight, obsoletely sinuate, nearly parallel, only slightly 

 converging from the base to within a short distance of 

 the apex, where they suddenly converge to the apex itself; 

 apical margin slightly produced ; upper surface finely 

 and subremotely punctured. Elytra sculptured as in the 

 last species. 



The two insects now described differ from the type of 

 the genus {Downesia insignis, Cat. Hisp. p. 107) in having 

 the fourth joint of the tarsus of normal length, and not 

 elongate ; there is also a slight difference in the length of 

 the joints of their antennee; but I do not consider these 

 characters of sufficient importance to authorize the forma- 

 tion of a new genus ; in habit, and in all other respects, 

 they agree entirely with the typical form.
