furrow beneath from the apex to the tooth, the mandibles 

 are rounded externally, the scrobes pass beneath the rostrum 

 in the basal third, and the margins of the joints of the 

 antennal club are very oblique. 



Deiradognathus fasciatus , sp. n. 



? . Colour black, partly clothed with dense brownish 

 cream-coloured scaling, and elsewhere with leaden-grey 

 scales variegated with blackish brown. The head creamy 

 with brown markings ; the entire prothorax creamy, except 

 a large dorsal hexagonal dark brown patch in the centre of 

 the basal half ; the elytra with dark scaling, except for a 

 small spot at the base of interval 6 and a broad irregular 

 transverse creamy band behind the middle, which widens 

 outwardly from the suture to the lateral margin and extends 

 along the margin to the base, being almost interrupted near 

 the suture by an oblique leaden-grey patch on intervals 2 

 and 3 ; the dark parts of the elytra are leaden grey, with a 

 slight sheen, variegated with velvety dark brown or blackish 

 patches, especially on the elevations ; the lower surface is 

 creamy, except the last three ventral segments, which are 

 dark with a row of pale spots down the middle and on each 

 side ; the legs creamy with large dark brown patches, the 

 apices of the femora and the lower surface of the tarsi 

 reddish brown. 



Head dull, with fine and very shallow reticulation and 

 scattered large deep punctures, but the sculpture is entirely 

 hidden by the erect scales, which are so densely packed that 

 only the" tips are visible. Rostrum convex and almost 

 parallel-sided in the basal third, thence flattened and 

 markedly widening to the apex; in the basal area the 

 punctation is very coarse and confluent at the sides, where 

 the scaling is dense, and the dorsal area bears separated 

 punctures of varying sizes ; the flattened anterior part is 

 much more sparsely punctate, and there is an undefined 

 impunctate central stripe. Prothorax almost as long as its 

 greatest width, the sides very strongly rounded, broadest 

 before the middle, the base Insinuate and broader than the 

 apex, which is somewhat produced over the head and sub- 

 truncate in the middle; across the widest part there is a 

 transverse row of four conical prominences and two others 

 near the front margin, all of which appear to be due to 

 elevations of the integument, but are really produced by 

 bunches of convergent upright scales ; the integument 

 itself, which is completely hidden, bears coarse separated
