Chalcites seems to be much less common and abundant, being found in 

 the Southern States north to Virginia, and westward to Texas, Missouri, 

 IlHnois, Nebraska and Kansas. Its colour is usually coppery, like the 

 bronze form of Icevis, which seems to be confounded with it by some of 

 the western collectors, and sent as that species to their correspondents, 

 while the name Icevis is applied to all mdividuals otherwise coloured. 

 This at least is my experience. However close the species may approach 

 in colour and sculpture they may be infallibly separated by the smooth 

 or granulated pygidium ; that of Icevis being always more or less 

 granulated, and that o'i chalcites entirely smooth and without polish. 



ApJiodius explanattcs Lee. The species was described by Dr. Leconte 

 from a female unique taken in Colorado, which was redescribed by Dr. 

 Horn in his monograph of the family. I am indebted to Mr. T. D. A. 

 Cockerell for a male example taken by him in Custer Co., Colo., and 

 note the following differences. The head is trituberculate with small but 

 well developed tubercles, and with the side margins indistinctly rufous ; 

 the thorax has the side mirgins rufous till near base, which is not rufous, 

 with the medial impressed line exceedingly fine and nearly reaching the 

 apex ; the first joint of the hind tarsus is equal to the two succeeding : 

 the club of the antennae is not darker than the stem, otherwise the 

 descriptions of the female apply. The mesosternal carina is quite fine, 

 and can be best seen when viewed transversely just in front of the coxse, 



Aphodius leopardus Horn. This species is taken at Sudbury, Ontario, 

 by Mr. John D. Evans. Heretofore recorded as occurring in eastern 

 Canada, Maine and New Hampshire. Pompophoea Sayi Lee. was likewise 

 taken at Sudbury.

Though not intended so by the describers, these names may be 

 regarded as representing the colour variations that occur in this species : 

 gazellula, pale-brown individuals ; gibbulus, such as have the anterior 

 half of the elytra ferruginous — the posterior piceous ; and niger, such as
