"Oblongo-ovatus, ater, subtiliter pubescens, dense punct- 

 ulatus ; thorace antrorsum valde angustato, lateri- 

 bus rotundatis, basi late rotundato; elytris versus 

 apicem obsolete striatis, stria suturali profunda ; an- 

 tennis thorace brevioribus, magis clavatis.

" One female : New York. This species is readily distin- 

 guished from the preceding (C. simplex) by the shorter, more 

 clavate antennae, which are only indistinctly testaceous at the 

 base ; the seventh joint is about twice as large as the sixth ; the 

 eighth is smaller than the sixth, and appears only about one- 

 third as large as its neighbours. The spines of the tibiae are 

 somewhat smaller than in the preceding species (simplex)*." 



2nd Subdivision. Thorax forming a continuous or nearly con* 

 tinuous line with the elytra ; middle tarsi of the males widened in 

 some species, in others not. 



In the last subdivision our arrangement led us gradually from 

 the species with slender antennae to those with the heaviest and 

 thickest-clubbed antennae. The affinity to these leads us now to 

 reverse this order, and to commence this subdivision with those 

 having similar thick antennae. 



A. Antennce heavily clubbed and middle tarsi widened in the males.
