Prothorax about once and one half as wide as long, sides strongly 

 rounded, base bisinuate and twice the width of apex; with an acute 

 continuous median carina, flattened and dilated at its base; with 

 dense, large, round, regular punctures, except at apex, where they 

 are small. M;/<ra subcordate, very little wider than protliorax; with 

 regular rows of rather large, round, deep punctures; interstices 

 stronglv raised and narrow, punctate and with transverse granules. 

 Under surface with dense and rather coarse, but more or less con- 

 cealed punctures. Mesosternal receptacle elongate, (J -shaped, f.egs 

 long and rather thin; femora strongly and acutely dentate; tibiae 

 compressed, feebly curved and longitudinally striated. Length

On the upper surface the scales are mostly rather small, of a 

 dingy grey or very pale brown, and not very densely distributed, 

 but on the posterior declivity they are more variegated and denser. 

 On the apical half or three fifths of the prothorax they are much 

 wider than elsewhere, and are prettily variegated. On tlie head they 

 are fairlv dense, large and variegated. The rostrum is nude, except 

 at the base. On the under surface the scales are rather dense but 

 feebly variegated and are smaller than the larger ones of the protho- 

 rax, but larger than most of the otiiers. The legs are densely clo- 

 thed. From the sides the elytral interstices appear to be very feebly 

 sinuated. 



DilTers from sUgmaticus atid verus in having the rostrum and legs 

 longer and thinner, with the tibite feebly curved and the mesoster- 

 nal receptacle (J -instead of V-shaped.

Black, antennae tibiae and tarsi more or less reddish. Rather den- 

 sely clothed with muddy-brown scales, interspersed with stout 

 semi-decumbent setae; rostrum glabrous except near base. 



Head with dense partially concealed punctures; inter-ocular 

 fovea deep and subtriangular. Rostrum long, moderately curved, 

 with coarse punctures on basal half, becoming subseriate towards 

 base and leaving a feeble median carina at basal third, apical half 

 with fine punctures. First joint of funicle stouter and slightly longer 

 than second, four apical joints the length of club. Prothorax sliglitly 

 transverse, basal half almost parallel-sided, sides strongly narrowed 

 to apex; with dense, round, partially concealed punctures. Elytra 

 about one fourth wider than prothorax at base; with series of large.
