25 (a). Cholus tessellatus 



(Tab. VIII. figg. 30, 30 



rf.) 



■ 



Oblong-rhomboidal, convex, shining, castaneous, the rostrum, antennae, and legs sometimes ferruginous (the 

 antennal club and the knees excepted) ; the depressed portions of the upper surface somewhat thickly 

 clothed with small, pale ochreous, oval scales (thus appearing closely, transversely tessellate), the sides of 

 the body beneath and the presternum densely clothed with similarly-coloured imbricate scales, the rest 

 of the under surface and the legs with scattered hair-like whitish scales. Head rugosely punctate 

 in front, foveate between the eyes ; rostrum arcuate, rather slender, longer than the head and prothorax, 

 in the <$ subcarinate at the base and somewhat closely punctate thence to about the middle, in the 

 $ much smoother. Prothorax strongly transverse, rapidly, arcuately narrowing from the base ; closely, 

 rather coarsely granulate, the squamose interspaces finely punctate. Scutellum oblong, closely punctate. 

 Elytra attenuate-cordate, the humeri strongly rounded; seriate-punctate, the interstices rather broad, 

 here and there confluent, and each with a series of flattened, polished granules, the seriate punctures 

 also separated one from another by a smaller smooth granule. Beneath densely punctate along the 

 sides, sparsely so down the middle ; ventral segments 1 and 2 hollowed down the middle in the <y . 

 Tibue with a sharp claw at the inner and outer apical angles. 



Length 10|-13, breadth 4§-5| millim. ( 6 $ .)

closely granulate and tessellate with smaller transversely confluent patches of ochreous 

 scales. The prothorax is short and strongly rounded at the sides, the last-mentioned 

 character separating C. tessellatus from C. pallidiventris, C. albiventris, &c.

2 . Moderately elongate, cuneiform, metallic brassy-green, the antennse and rostrum black, the legs cseruleous ; 

 the head, prothorax, and base of the rostrum sparsely set with small, narrow, whitish scales, the 

 foveiform depressions of the elytra each with a dense transverse cluster of similar scales ; the under 

 surface densely clothed with much larger and broader pale ochreous scales, those on the last two ventral 

 segments narrow and hair-like ; the legs with scattered whitish hairs. Head closely punctate, feebly 

 foveate between the eyes ; rostrum moderately stout, about as long as the head and prothorax, almost 

 straight, the basal portion closely punctate and finely carinate, the apical portion flattened, polished, and 

 very sparsely, obsoletely punctate, the antennae inserted at the middle. Prothorax broader than long, 

 subconical, rounded at the sides posteriorly, and feebly constricted in front; transversely rugose. 

 Scutellum rather large, finely punctured. Elytra cuneiform, less than twice the length of the prothorax ; 

 closely seriato-foveolate, the fovese subquadrate and here and there transversely confluent, the narrow 

 raised interspaces almost smooth, except along the suture. Beneath densely punctate. Posterior femora 

 extending far beyond the apex of the elytra. Posterior tibiae with a smooth claw at the outer apical 



angle. 

 Length 11, breadth 4| millim.
