710 Coleopterological Notices, IV. 



The two specimens in my cabinet were kindly communicated by 

 Mr. Chas. Fuchs, who discovered them while sifting mouldy earth 

 amonii- the red-woods north of San Francisco. 



II. 

 CYCLOSATTUS n. gen. (Tenebrionidse). 



The species which I described under the name Eusaftus websteri 

 (Col. Not., Ill, p 5fi) has the outline and general habitus of cer- 

 tain forms of Eusattus, but was placed in that genus without due 

 examination of its generic characters; these I find to be very dif- 

 ferent, and, in order that the species may be understood, it is neces- 

 sary to refer it to a new genus far removed from the Coniontini. 

 It forms the second of the only two known North American generic 

 types of the tribe Opatrumini (Col. Not., II, p. 391), the other one 

 being Ephalus Lee. The principal characters may be given as 

 follows : — 



Bofly very broadly, evenly oval, rather strongly convex, the margins of 

 the pronotum broadly, and of the elytra narrowly, reflexed. Head promi- 

 nent at the sides before the eyes, transversely truncate at apex. Eyes trans- 

 verse, emarginate at the middle. Anterior, intermediate and posterior coxse 

 equally and not very widely separated, the abdominal process narrow and 

 obtusely angulate at apex. Legs not very long but slender, the anterior 

 tibiae with an externally produced apical process, the internal spur very 

 minute ; intermediate and posterior with two small slender terminal spurs. 

 Tarsi slender, short, slightly compressed, coarsely pubescent beneath, the 

 basal joint of the posterior not quite as long as the remaining three combined. 

 Elytra widely embracing the body, the epipleurse very wide, especially toward 

 base. Third and fourth abdominal sutures fine, vertical and coriaceous. 



On examination of the under surface the epipleuras appear at 

 first to attain the elytral apices, but this is not so in reality, the 

 portion attaining the sutural angles being the narrow reflexed 

 margin of the elytra, the plane of the under surface of which 

 makes a strongly marked angle with that of the epipleurte proper, 

 throughout the entire extent. 



Mr. F. Blanchard of Lowell, to whom I am indebted for calling 

 my attention to the fact that luehsteri could not be retained in 

 Eusattus, tells me that Dr. Levette found this specimen at Pueblo, 

 Colorado, but whether collected there or otherwise obtained he is 

 unable to state. I see no reasonable grounds for doubting its
