Cephalodesmius laticoUis. 



C. uiger, opacus ; clypeo aiitice bideiitato, dentibus duobus mediis basi 

 separatis ; protliorace elytris latioro. 



ILib. Queensland. 



Dull black, opake ; head very transverse ; the clj-peus four-toothed, 

 the two central teeth longest, linear, subparallel, and widely separated 

 at the base ; prothorax very broad, wader 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. 



DiATELiuM [Scaphididae]. 

 Caput collo elongate ; oculis magnis, integi'is, rotundatis. Antennce graciles, 

 clava quinque-articulata. Palpi subulati, acuti. Scutellmn liberum. 

 Pedes elongati, tihiis bicalcaratis. 3Iesosternum carinatum. 



Notwithstanding the extraordinary form of this insect, owing to 

 its exceedingly long neck, it is very closely allied to ScapJiidium, 

 differing from it principally in that respect and in its entire and 

 prominent eyes. As in the Scaphididte 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 ; antennae pale testaceous, short, arising from 

 a roimd 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 ; coxae, base and extremity of the 

 femora, the mesothorax, and the epistema of the metathorax, as well 

 as its posterior border, black. Length 6 lines.
