along the suture and two or three on the inflexed sides ; the 
spaces between the punctures, where visible, shining and 
coriaceous; the scales small, nearly circular, convex, and 
shiny ; the stout flattened setie irreg gularly placed and nearly 
recumbent. 
Length 84 mm., breadth 44 mm. 
Carre Cotony: Hex River. 
Described from a single specimen. 
Genus Cycurotonus, Pasc.* 
As a result of following Faust’s interpretation of the 
genus Chaunoderus, Gerst., I sank C ychrotonus as a synonym 
of it (Proce. Zool. Soe. 1906, p. 958). It is now clear that 
under Chaunoderus Faust associated insects having two 
distinct types of antennal scrobes. In the genotype, 
C. stupidus, Gerst., with which I am not acquainted, the 
scrobes are described as being of a normal Otiorrhynchine 
type—superior, directed straight towards the eyes, and 
disappearing a little before the middle of the rostrum ; 
whereas in Cychrotonus they curve downwards in front of 
the eye and extend to the base of the rostrum. Of the 
described species of Chaunoderus known to me, the following 
must be referred to Cychrotonus:—C. marginalis, Vst., C. 
subglaber, Fst., °C. sternalis, Hartm., and C. apicalis, Hartm.; 
whereas C. brevicollis, Fst., and C. transversus, Fst., may 
provisionally remain in Gerstaecker’s genus. 
Cychrotonus ellipticus, sp.n. (Pl. I. fig. 7.) 
3 ?. Black or piceous, practically devoid of scaling 
above; the lower surface of the head and rostrum, the 
sternum, and cox with scattered, flat, bluish seales; the 
venter with numerous elongate, narrow, curved, whitish 
scales. 
Head with rather coarse, longitudinally confluent puncta- 
tion, the forehead flat, but not noticeably depressed below 
the vertex; eyes rather less convex than usual, deepest in 
the middle and bounded internally by a deep furrow. 
Rostrum longer than broad, rather broader near the base 
than at the gene, the sidcs sinuate in the middle ; coarsely
