are decidedly wider than the prothorax, with nine rows of large 

 coarse punctures, those on the disc running in stride, which are 

 well defined near the base, but fail near the apex. There are 

 also some coarse punctures scattered about the elytra inde- 

 pendently of the rows. The pygidium in both sexes is punc- 

 tured in front and smooth behind. The legs do not appear to 

 differ in the sexes ; the anterior tibiae are tridentate externally. 

 The ventral segments are very much shorter in the male than 

 in the female.

iV^. (?) occidentalism sp. nov. Supra piceo-niger ; antennis palpis 



pedibusque ferrugineis ; nitidus ; subtus longe sat dense 



fulvo-pubescens ; elytris vix evidenter striatis, obscure 



seriatim punctulatis. Long. 6f 1., lat. 3^1.

Clypeus transverse, its front margin subtruncate and quite 

 as wide as its base, its sides and front angles somewhat 

 rounded, its edges not sharply defined, its surface somewhat 

 concave transversely. Head abruptly depressed behind the 

 clypeus, so that viewed from behind there appears to be a 

 raised keel (which does not really exist), limiting the clypeus 

 behind ; the frontal depression is not distinctly limited behind, 

 and is vaguely narrowed backwards. The head and clypeus are 

 rather closely roughened, but hardly distinctly punctured. 

 Prothorax sparingly and very finely punctured (scarcely per- 

 ceptibly without a very strong lens), except in the depression, 

 where the puncturation is coarser ; the depression is nearly 

 round, and occupies the middle third part of the width and the 

 anterior third part of the length of the thorax. The anterior 

 margin of the prothorax is scarcely half as wide as the base, it 

 is moderately emarginate and is raised into a sharp tubercle 

 in the middle; the sides diverge backward for the first 

 third part of their length and then (viewed from above) 

 appear to continue nearly parallel to the base, which is 

 scarcely bisinuate. The real margin is invisible from above 

 and is regularly rounded. The anterior angles are acute, the 

 posterior roundly obtuse. The scutellum is roundly triangular, 

 smooth, and with an impressed line down the middle. The 

 elytra have a well-defined sutural stria and faint suggestions of 

 other strias here and there. The}^ are sparingly and faintly 

 punctured, the punctures in places tending to run in rows. 



I attribute this insect only with hesitation to the genus 

 Seocavonus. It is a narrower and more elongate parallel spe- 

 cies than any other Oryctomorjphidce known to me. Its mentum,
