three-fourths wider than the prothorax, at apical fourth nearly four times as 

 wide as the latter, about two-thirds longer than wide, each with two discal 

 and one marginal fine feebly elevated lines, the disk very dull, minutely and 

 strongly granulato-reticulate but not punctate. Legs rather long and very 

 slender. Length 9.8-11.8 mm. ; width 4.6-6.0 mm.

The sexual modification of the abdominal apex is not at all con- 

 spicuous in the two males before me. 



CTJRCULIONKLE. 



Cleonini. 



The subgenus Apleurus of Chevrolat is somewhat comprehensive, 

 but as represented b}' A.fossus, apparently intended by the author 

 as the generic type, it may be described in general terms as having 

 the beak flattened, thick and broad, and more or less devoid of me- 

 dial carination, the tarsi with pads of dense pubescence beneath, 

 the elytral maculation confused or at least non-vittate, and the 

 prothorax angulate and constricted anteriorly at the sides. These 

 characters all pertain to the groups separated by LeConte under 

 the names Cleonopsis and Cleonaspis. 



It seems to be impossible to separate the species allied to the 

 typical Cleonus of Europe into groups which can in any way be 

 considered of generic value, and, as far as our own fauna is con- 

 cerned, there are apparently but three distinct genera which may 

 be defined as follows : — 



Prosternum with an erect spiniform process before each coxal cavity ; tarsi 

 extremely coarsely and sparsely spinose beneath, without trace of densely 



pubescent brushes DinocleilS 



Prosternum normal, without spiniform processes ; tarsi with brushes or pads 

 of yellowish-brown pubescence beneath. 

 Beak thick, more or less dilated toward apex ; densely pubescent pads some- 

 times imperfectly developed or obsolete on the posterior tarsi... CleoilllS 

 Beak slender, cylindrical and more arcuate, generally not appreciably 

 dilated at apex ; body less stout, often very slender LixilS 



MNOCLEUS n. n. 



Centrocleonus || Lee. 



The species of this distinct genus are more robust and oval in 

 outline than in Cleonus, and are readily distinguishable by their
