surface confusedly aud finely punctate, the punctures not very 

 close to each other, and stronger than those on the pronotum.

Type of Altica troglodytes (Bengal, Coll. Mace) in the Museum 

 d'Histoire jNaturelle, Paris ; tho^se of S. pallidipennis and S. fulvi- 

 joennis in the British Museum. 



Having carefully examined the types of S. pallidipennis and 

 S. fulvipennis, I am of opinion that they are the same species. 

 Probably Baly was justified in keeping them separate, not having 

 many specimens before him. I believe that this species has a wide 

 distribution, but the variation is not, apparently, correspondingly 

 great. 



308. Sebsethe perata, sp. nov. 



Body broadly ovate, shining. Colour of the head, the three 

 basal segments of the antennas, the pronotum, a broad border all 

 round the elytral margins, and the suture, dark brown to light 

 yellow ; the eight apical segments of the antennas and the elytra 

 black, but in one example the lighter colour of the suture extends 

 from the apex forwards to behind the middle ; in one case, also, 

 the central part of the pronotum is fuscous ; scutellum sharing 

 the colour of the pronotum ; underside fuscous or blackish ; legs 

 sometimes piceous, with the points of articulation and the tarsi 

 darker in one example, but in the other the legs are lighter ; 

 epipleura of the elytra always lighter than the rest of the 

 underside. 



Head with vertex impunctate, frontal tubercles with a fine 

 longitudinal impression between them and separated from the 

 vertex by a transverse impression in the interocular space, inter- 

 antennal carina sharply raised, Antennas slender; first segment 

 long and club-shaped, second short, third longer than second, 

 fourth slightly longer than third. Prothorax much broader than 

 long, sides rounded, with their margins somewhat explanate and 

 reflexed, anterior lateral angles somewhat produced and thickened ; 

 surface very sparsely and finely punctate. Scutellum triangular, 

 with apex rounded and surface smooth and impunctate. Elytra 

 hardly broader at base than prothorax ; surface more or less 

 closely, finely and confusedly punctate, the punctures being
