304 1*HE ENTOMOLOGIST. 



Say ; and two Elateridse which came to the camp-fire, 

 Anelastes drurii, Kirby ; and Asaphes memnoniuSy Herbst. I 

 should also say, that I found sundry Myriapods in the canon of 

 the genera, Jidus, Lithobius, and Geophilus. From Wales Canon 

 we drove across some dry country, till we struck the St. Charles 

 Eiver, and got in a valley through which it flows, termed " Mace's 

 Hole." On the way we j)assed specimens of Solanum rostratmn, 

 which is the natural food-plant of the Colorado potato-beetle, 

 but never a sign of Doryphora (or Leptinotarsa, if v/e are to call 

 it so). There is not very much to say about this district 

 entomologically ; we camped near the county boundary, but in 

 Pueblo Co., and there I got a grasshopper, probably Trimero- 

 tropis vincidata, Scudd., or a variety of it, and a specimen 

 of Carahus serratus, Say, while one of the ladies brought to 

 camp two fine Cetoniids, which were found on a thistle-flower ; 

 they prove to be Euryomia inda, L. The next morning, just in 

 the last bit of Pueblo Co., I saw a Pierid butterfly, new to me, as 

 we drove along ; it was captured, and is now identified by Mr. W. 

 H. Edwards, as Neophasia mejiapia, Feld., and he adds that the 

 larva feeds on the leaves of pine trees (remarkable food for a 

 Pierid), and in Washington Territory and Oregon does much 

 damage by defoliating the trees. The eggs, he says, are laid in 

 rows, touching each other, and placed obliquely on the leaf ; so 

 altogether this is a very aberrant species in its earlier stages, not 

 like a Pieris at all. 



Now we return to the Hardscrabble district in eastern 

 Custer Co. on the journey homewards. By the south fork of the 

 Hardscrabble Creek, the galls of Rhodites tuhcrcidator, Piiley, are 

 met with. Later, in the Hardscrabble Caiion, we met with a few 

 insects new to the district, Pyrameis liuntera, Chrysophanus 

 zeroe, Bdv., Bomhus rufocinctus, Cress., and the curious spotted 

 beetle, Erotyliis boisduvalii, Lac. Then, at Comargo again, a 

 fine Longicorn beetle, Leptura canadensis, Oliv., is found ; and 

 this ends the list, except for a few species brought home, of 

 which the precise locality was unfortunately not noted down, 

 viz., a Satynis, which Mr. W. H. Edwards tells me is the western 

 form of S. nephele, from S. W. Pueblo Co. ; and Pholisora 

 catidkis, Fab., E. Custer Co.; while Ilyhius picipes, Kirb. ?; 

 Aphodius lividus, Oliv. (new for Colorado) ; and Saprinus orcgo- 

 nensis, Lee, were from the Hardscrabble district in E. Custer
