Head witli front concave and coarsely punctured. Eyes 

 moderately close together. Rostrum moderately long; basal 

 half with very coarse punctures, and with a very feeble ridge, 

 apical half with sharply-defined punctures. Profhorax almost 

 twice as wide as long, sides rounded and feebly increasing in 

 width to near apex, and then suddenly and strongly narrowed 

 so that the apex is only half the width of the base; with 

 large round punctures crowded together but usually nowhere 

 confluent; with a strongly elevated, narrow, median carina. 

 Elytra oblong-cordate, no wider than widest part of pro- 

 thorax; with rows of large deep punctures in feeble striae, 

 and becoming smaller posteriorly; third, fifth, and seventh 

 interstices distinctly raised, and, as some of the others, with 

 partially - concealed squam.iferous granules. Metasternum 

 with a moderate and interrupted ridge on each side between 

 coxae; episterna each with a continuous row of strong punc- 

 tures. Ahdomen with first segment feebly concave, and some- 

 what shorter than usual ; third and fourth each with a semi- 

 double row of punctures across middle. Legs moderately 

 stout; femora strongly dentate; all tibiae somewhat thin, 

 lightly curved, and not dilated to apex. Length, 4-6^ mm. 



9 . Differs in having the rostrum longer, thinner, more 

 shining, and with smaller and sparser punctures, prothorax 

 Jess dilated in front, with its widest portion nearer base than 

 apex and less than width of elytra ; and basal segment of 

 abdomen moderately convex.

A rather distinct species on account of the prothorax of 

 the male. The side of each elytron has a subtriangular dark 

 patch, largely, but not entirely, due to absence of ashen scales ; 

 the few scales present on it are all sooty, the patch usually 

 extends to the fifth interstice, but sometimes to the second, it 

 commences on the shoulder, and terminates level with the 

 fourth abdominal segment, or thereabouts. On some speci- 

 mens there appear to be four longitudinal stripes on the pro- 

 thorax, and one transverse one, but the linear arrangement 

 is more or less broken up. The depression behind each eye 

 is unusually deep, and the two are dilated till they meet in 

 front, causing the whole front of the head to appear concave, 

 with a quadrisinuate forehead, as in many of the allies of 

 Poropterus. In siihopacus it is somewhat similar but less 

 pronounced. The elytral punctures, although large, are 

 partially concealed by the clothing, but on the sides their 

 full extent is usually distinct.
