“I 
Genera and Species of Coleoptera. 
CrpHatopesmivs [Scarabeidee |. 
Westwood, Trans. Ent. Soc. 1 ser. iv. p. 117. 
Cephalodesmius laticollis. 
C. niger, opacus; clypeo antice bidentato, dentibus duobus mediis basi 
separatis ; prothorace elytris latiore. 
Hab. Queensland. 
Dull black, opake ; head very transverse; the clypeus four-toothed, 
the two central teeth longest, linear, subparallel, and widely separated 
at the base ; prothorax very broad, wider than the elytra, and present- 
ing an almost foliaceous margin at the side anteriorly ; elytra obsoletely 
striated, slightly convex, almost concave towards the shoulder; body 
beneath and legs dull black; palpi ferruginous. Length 7 lines. 
Well distinguished from Cephalodesmius armiger, Westw., the 
only species of this genus hitherto described, by the slight convexity 
of its upper surface, the breadth of the prothorax, by the direction 
of the two central teeth of the clypeus, and their separation at the 
base. The head is also broader and shorter, the legs longer, and the 
abdomen more contracted. 
Dratetrum [Scaphidide }. 
Caput collo elongato ; oculis magnis, integris, rotundatis. Antenne graciles, 
clava quinque-articulata. Palpi subulati, acuti. Seutellum liberum. 
Pedes elongati, tibtis bicalcaratis. Mesosternum carinatum. 
Notwithstanding the extraordinary form of this insect, owing to 
its exceedingly long neck, it is very closely allied to Scaphidium, 
differing from it principally in that respect and in its entire and 
prominent eyes. As in the Scaphidide generally, the abdomen has 
six segments, and the prothorax and elytra have the same peculiar 
punctation. Mr. Wallace has taken it both in Sumatra and in Borneo. 
Diatelium Wallacei. (PI. II. fig. 2.) 
D. fulva, nitida; capite, prothoracis basi et medio, elytrorum macula 
discoidea clavaque antennarum nigris. 
Hab. Sumatra; Borneo (Sarawak). 
Fulvous yellow, very smooth and shining; head and neck nearly as 
long as the rest of the body together, black, the latter finely corrugated 
transversely ; eyes fulvous; antennz pale testaceous, short, arising from 
a round fovea in front of each eye, the last five joints black, forming a 
loose club; prothorax rounded anteriorly, convex, the middle and base 
black ; scutellum black ; elytra rather depressed, a large black discoidal 
spot on each; body beneath fulvous; cox, base and extremity of the 
femora, the mesothorax, and the episterna of the metathorax, as well 
as its posterior border, black. Length 6 lines.
