Mr. A. Murray's Monograph of the genus Catops. 307 



The above is Dr. Lcconte's description ; the following is Say's : 

 " Pale brownish, sericeous ; terminal and five basal joints of 

 the antenna) rufous. Inhabits Arkansas. Head dark ferru- 

 ginous ; antennfc dark ferruginous, the five basal joints and 

 terminal joint rufous; palpi and mandibles ferruginous; thorax 

 rather paler than the head, quadrate, a little transverse, sides 

 regularly arcuated ; posterior margin not wider than the ante- 

 rior ; posterior edge rectilinear ; angles rounded ; elytra paler 

 than the thorax, light brownish, with obsolete stripe, more ob- 

 vious towards the tip; very numerous minute punctures fur- 

 nishing minute hairs ; beneath piceous ; feet rufous ; thighs yel- 

 lowish beneath. Length nearly ^ijtbs of an inch. This species 

 occurred on dung*." 



Dr. Leconte in speaking of his species remarks, that he is not 

 positively certain that it is Say's species, which was found in 

 Arkansas, while his was from New York. He adds, " The thorax 

 is more narrowed in fi'ont than described by him ; although the 

 legs are in reality black, the lustre of the fulvous hair is such, 

 that one might readily be tempted to describe them as testaceous 

 at base."

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

 ulatus ; thorace autrorsum valde angustato, lateri- 

 bus rotundatis, basi late rotundato; elytris versus 

 apieem 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 antenna?, which arc 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 tibise are 

 somewhat smaller than in the preceding species {simplex) f ." 



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
