Nearly Mack. The base of the third antenna] joint, the base of 

 the palpi, the base of the femora, and the coxa? obscure testaceous. 

 The thorax has the central areolet well defined, extending from the 

 base to the anterior margin ; the ridges which divide the lateral 

 areolets are Bomewhat obscure ; the anterior margin is finely punc- 

 tured. Of the four costa? on the elytra, the second and fourth are 

 the more distinct, bul none of them extend to the apex; the inter- 

 stices have very numerous transverse ridges, which are very irregular 

 and sometimes interrupted; towards the apex of tho first interstice 

 and in the fifth there are indications of an irregular intermediate 

 longitudinal costa. The penultimate segment of the abdomen has a 

 deep semicircular emargination. 



TAPHES. 



Waterh., Trans. E>it. Soc., 1878, p. 102. 



Insect rather short, having a velvety appearance. Antenna? 

 scarcely dentate, beset with long fine hairs in the male. Thorax 

 small, transverse, with a large lozenge-shaped discoidal areolet, its 

 angles nearly reaching the margins. Elytra rather enlarged poste- 

 riorly, quadricostate ; the interstices with two lines of punctures, 

 these lines scarcely divided by a costa.

"With a velvety appearance above. Antenna? dull, compact. 

 Thorax a little narrowed in front, straight at the sides, with the
