the tuberculate surface of the gula ; the biicculae thin carinate, feebly elevated 

 and widely separated, the rostral groove consequently shallow but very broad, 

 and not at all completely filled by the rostrum. Pronotum ((^) about one and 

 three-fourths wider than long in the middle (65 : 37), lateral margin sinuate, the 

 posterior third convex, the centre concave and the anterior third convex ; the 

 anterior lateral angles distinctly but obtusely produced anteriorly in front of 

 the anterior margin which is slightly emarginate and much narrower than the 

 posterior margin (30 : 62) which is also broadly emarginate ; lateral margins 

 anteriorly more or less reflexed, disc tuberculate especially the posterior lobe, 

 calli slightly elevated, a short longitudinal ridge on each side of the anterior 

 lobe between the calli and the reflexed lateral margin. Scutellum triangular 

 the sides almost straight, slightly concave towards apex and equal in length to 

 the base ; lateral margins slightly reflexed or carinate ; surface transversely 

 rugose with a median longitudinal carina. Hemi elytra scarcely reaching genital 

 segment ((^), the inner angle of corium and apex of clavus reaching the apex of 

 scutellum ; claval suture and corial veins obscurely granulate ; membrane with 

 some almost obsolete irregular reticulations but no longitudinal veins, about 

 twice as long as the corium. Legs simple, femora unarmed. Abdomen not 

 dilated but connexivum broad, venter distinctly convex, lateral margins of 

 sixth and seventh segments distinctly concave ; spiracle of second segment 

 (first apparent) on the lateral edge of connexivum, remaining spiracles, on its 

 ventral surface, the fifth and sixth spiracles somewhat closer to the lateral 

 margin than the others.

This species has been provisionally referred to the genus Pictinus Stal., 

 owing to its general resemblance to Pictinus invalidus Bergr. (Seychelles), from 

 which it differs however in the more slender and shorter antennae, absence of 

 constriction of the tylus before the apex ; absence of post ocular processes, 

 more prominent antenniferous spines, flatter head, emargination of posterior 

 margin of pronotum and in the j)osition of the first visible spiracle (second 

 abdominal) on the lateral edge of the connexivum. It is very probable that
