" I have been really at a loss to know to what genus to refer these

 ber of the stria- and their character forbid sm-li a reference. Tin- >pecies

 undoubtedly resembled it in form. I would have referred the remains to

The thorax of the specimen appears to have been broken oil' before 

 reaching me, as the description given by I >r. I lorn is inapplicable to anv of 

 the fragments before me. 



The pleurae are not only "longitudinally finely strigo.-e." but also 

 delicately striate in the same direction. Aside from the punctuation the 

 upper surface of the thorax is smooth. 



The outer discal stria of the elytra is very widely separated at base 

 from the BUbmarginal stria which runs closely parallel to the outer border.

The insect evidently appertains to a distinct genus of Ptinida-, in which 

 the sides of the bodv are not parallel, but the bodv tapers posteriorly much, 

 though not to the same extent, as anteriorly. It is. however, most nearly 

 allied to Anobium. in wjiidi it is provisionally placed. It N about as l.-ir-e 

 as Endecatomua rugosus LeC. The prothorax, viewed frum alio\-e. is 



bluntlv conical, taperini;- rapidly. The bodv is broadest just liehind t!ie 

 base of the elvtra, and tapers slightly at first, more rapidlv afterward, and 

 is rounded posteriorly; tlius the whole bodj has an ovate outline. The 

 proiiotum is minut-l\ and very profusely punctulate in lilack, the punctures 



being slightly elongated longitudinally, and appears to have been covered 



profusely with slight asperities or a coarse pile -much perhaps as in Knde-
