tion a specimen of an already descfibed Euparia for comparison. 

 Lacordaire speaks of the genus as consisting of two divisions, the 

 second of whicli appears to have been sul>sequently separated by 

 Harold as the aggregate on which he founded Ataenius. 

 Lacordaire distinguishes his second division of Euparia [of which, 

 he says, the type is E. (Aphodius) stercorator. Fab.] from the 

 tirst by the apex of the frontal dilatation on either side of the 

 head being obtuse (acute in the first division), by the base of the 

 prothoiax being gently rounded (very sinuate near the hind 

 angles, in the first division), and by the absence of a strongly 

 developed humeral spine of the elytra. Harold (Ann. Mus. Gen., 

 1877, p. 97) mentions some other characters, speaking of Atae- 

 nius as "perfectly distinct from Euparia by its prothorax not 

 depressed on the sides, by its legs not elongated, and by its 

 straight posterior tibiae." The insect before me presents all the 

 characters indicated above as distinctive of Euparia, and there- 

 fore I have no doubt of its being a member of that genus.

This species has a quite remarkable superficial resemblance to 

 a liliputian Cryptodus caviceps, Westvv. It was given to me 

 many years ago by the late Mr. A. S. OUiff.
