452 Mr. F. P. Pascoe on new Curculionide. 
has a contour decidedly foreign to Mecocorynus; in that genus 
the club of the antenne is peculiarly elongate and cylindrical. 
‘he species here described are not altogether homogeneous ; 
and it would not be difficult to find characters which might 
separate them into genera. 
Arypteus suturalis. (Pl. XVIII. fig. 6.) 
A. obovatus, fuscus, squamis ferrugineis variegatus: elytris nigro- 
fasciculatis, postice latioribus, sutura basifulvo-marginata. Long. 
4 lin. 
Hab. Sarawak. 
Obovate, brown, covered principally on the elytra with small 
ferruginous scales, their sutural margin at the base fulvous ; 
rostrum moderately long, the base with five raised lines 5 an- 
tenne antemedian, ferruginous, the second joint of the funicle 
a little longer than the first ; prothorax oblong, subcylindrical, 
with four fascicles of short black hairs, coarsely punctured, 
each puncture filled with a round concave scale; scutellum 
elongate, glossy black, rounded behind ; elytra much broader 
than the base of the prothorax, gradually broader behind, 
slightly striate, strie with large squarish punctures, the inter- 
stices more or less tuberculate, the third interstice with three 
tufts of erect black scales ; legs and body beneath with long 
pale scales and setee. 
Arypteus pustulosus. 
A. subovatus, niger, squamulis ochraceis brunneisque varius; elytris 
fere parallelis, tuberculis octo fronteque lete ochraceis. Long. 
4 lin. 
Hab. Cambodia. 
Black, closely covered with ochreous-yellow and reddish- 
brown scales and setule, the former more conspicuously 
confined to the forehead, rings on the legs, and eight round 
spots on the elytra, viz. two basal, two humeral, and four in 
a transverse direction posteriorly, the two central of the latter 
tufted ; rostrum moderately long, without raised lines; an- 
tenne pale ferruginous, first two joints of the funicle subequal ; 
prothorax slightly transverse, irregularly fasciculate anteriorly ; 
scutellum black, scutiform ; elytra striate-punctate, punctures 
mostly bearing a whitish scale, interstices convex; body 
beneath with approximate smooth convex scales. 
A very different contour from the last and a different colora- 
tion. The scales beneath resemble small Acarz. It is pro- 
bably Cryptorhynchus pustulosus of Dejean’s catalogue.
