New American Cleridae, with notes on others (Col.). 



By A. B. WOLCOTT, Chicago, 111. 



The material forming the basis of the present article was 

 recently received from Prof. H. F. Wickham, by whom it was 

 collected and to whom my thanks are due for having gener- 

 ously placed in my hands for study all his unique and most 

 valued specimens. Nearly all the species herein described as 

 new are forms differing greatly from their nearest allies and 

 should prove of easy recognition. 



CALLOTILLUS gen. nov. 



Body elongate, moderately convex, winged. Labrum short, 

 transverse, truncate; eyes small, finely granulate, internally 

 deeply emarginate ; last joint of maxillary palpi subcylindrical, 

 of labial palpi securiform ; antennae lo-jointed, joint one mod- 

 erately large ; joint two small, suborbicular ; joint three elon- 

 gate, triangular, longer than joint one ; joints four to nine tri- 

 angular, much larger than preceding joints, as broad as long; 

 joint ten compressed, longer than the two preceding joints to- 

 gether, obtusely rounded at apex. 



The species for which this genus is erected is Clerus-like in 

 form. The structure of the antennae recalls both that of Tiliits 

 and Monophylla. The third joint of the antennae is elongate 

 triangular, but much narrower and more elongate than the suc- 

 ceeding joints. The legs are slender and moderately long. 

 The tarsi, five joints of which are visible from above, are 

 scarcely one-half as long as the tibiae; they are feebly dilated 

 and joints two, three and four are lamellate; the claws are 

 bifid, the inner division slightly shorter than the outer portion 

 and furnished with a strong tooth at base. Five segments of 

 abdomen visible. 



The structure of the tarsi and the antennae bring this genus 

 into the group Tillini, where it is best placed between Mono- 

 phylla Spin, and Tillus Oliv. 



Type of the genus is the following new species: 



Callotillus eburneocinctus sp. nov. 



Rufous, subopaque; meso- and metasternum rufo-piceous; abdomen 

 black, shining, posterior margins of ventral segments pale; antennae
