STEXYGEINUM. 163 



duplo, in aliis parum longiores." He 'probably confounded two 

 distinct species, belonging perhaps to different genera, under the 

 same name. The present species is quite distinct from all others 

 included in the Indian fanna ; it is very closely allied to C. unicolor, 

 Fab., a widely distributed species found in the Oceanic islands. 



Genus SALPINIA. 

 Salpinia, Pascoe, Trans. Ent. Soc. (3) iii, p. 646 (1869). 



Type, 8. diluta, Pasc., a species from Borneo. 



Range. Assam, Penang, Borneo, and Java. 



Very closely allied to and scarcely distinct from Ceresium, 

 Newm. The only points of difference are that the femora are 

 gradually and less strongly thickened, and that the fourth antennal 

 joint is distinctly longer than the first and very little shorter than 

 the third. 



Two species of the genus are known one from the Patkai Mts. 

 in Assam, the other from Penang, Borneo, and Java. 



176. Salpinia socia, sp. n. 



Testaceous red, with the elytra yellowish ; the legs brownish 

 black, the basal half of the middle and hind femora yellowish, 

 the tarsi and apices of the tibia3 reddish brown or brown. Head 

 faintly covered in parts with golden pubescence. Antennae of $ 

 one-third or so longer than the body ; first joint feebly punc- 

 tulate; third slightly longer than the fourth, which is nearly 

 one-third longer than the first; fifth subequal to the third. 

 Prothorax about one-fifth longer than broad, slightly rounded 

 at the sides; sparsely but strongly punctured, the sides and base 

 covered with short grey pubescence which gives silvery reflec- 

 tions. Elytra rather faintly covered with short, pale pubescence ; 

 distinctly but not very densely punctured from the base to within 

 one-fifth or one-sixth from the apex. Femora gradually and not 

 strongly thickened from the base for about four-filths of their 

 length, and then narrowed towards the apex ; the hind pair 

 extended just a little past the apex of the elytra ; fourth joint of 

 the hind tarsi slightly longer than the second and third united. 

 Body beneath faintly covered with silvery-grey pubescence, which 

 becomes more visible in certain lights. 



Length 9 ; breadth 2 mm. 



Hab. Assam : Patkai Mts. (DoTierty). 



This species is closely allied to S. diluta, Pasc., but easily distin- 

 guished from it by the absence of markings from the elytra. 



Genus STENYGRINUM. 



Stenygrinum, Bates, A. M. N. H. (4) xii, p. 154 (1873). 



Type, S. quculrinotatum, Bates. 



Range. One species only is known, which ranges from Assam 

 and North Burma through China and Japan.
