This species is placed here with hesitancy on account of tlie great lenf;;th 

 of the snout, but its general resemblance to the other species seems other- 

 wise considerable. The head is very delicately and faintly granulate, as is 

 also the rostrum, which is very gently arcuate, and slightly longer than the 

 protliorax. The head, however, shows somewhat of a transverse aiTange- 

 ment of the granulations, giving a subcorrugate appearance. The protho- 

 rax has a similarly delicate, circular, but more distinct and densely crowded 

 granulation. The sculpture of the elytra is vaguely preserved, but appears 

 to be nuich as in the preceding species.

AULETES Schonherr. 



This genus, of which five species are recognized in the United States, 

 is otherwise known j)rincipally from southern Europe and the Mediterra- 

 nean district, l)ut ;i couple are fotuid in Tasmania. They are insects of 

 small size, closely allied to Rhynchites. They have not before been recog- 

 nized in a fossil state, and but a single specimen has been found at Floris- 

 sant, Colorado.

A species agreeing very nearly with our A. afer Le C, except in the 

 apparently stouter thorax, striate elytra, and slenderer antennal joints. 

 Head transversely striate and faintly punctured, with moderately small 

 circular eyes; beak considerably shorter than the head and prothorax,
