"Revision of the species of Polyphylla of the United States," by 

 Geo. H. Horn, M. D. 



Dr. LeConte made the following observations on the synonymy and 

 habits of various Coleoptera of the United States, gathered mostly 

 from his observation and correspondence of the last month. 



1. Synonymy. — Cleronomus oniatkollis Lee, is an extreme % 

 variety of the well known Olerm thoracicus Oliv. The antennae of the 

 % are much more slender than those of the $ , formed as in Cleronomus, 

 which might probably be suppressed as a genus. The accumulation 

 of larger series of specimens shows that the prothorax varies in color 

 from almost entirely black to almost entirely yellow. 



Clems ? tantillus Lee. — Mr. Schwarz has kindly sent me a specimen 

 from Alabama, found preying upon the larvae of an undescribed Cis, 

 in a woody fungus. The proaotum bus a moderately distinct marginal 

 Tie, but the insect otherwise resembles in miniature Thaneroclerus 

 sanguineus^ so that I think it is not possiLls to refer it to the Corynetes 

 group. 



Myodites Svhwarzi and Zeschii are respectively % and $ of the 

 same species; in the former the vertex is less elevated and the antennae 

 are black; in the latter the vertex is acute and the antennae are 

 brownish-yellow. This species has been raised by Mr. Hubbard from 

 the cells of Augochlora pura Say. J/. Wahhii is very near this species 

 but has the hind tibiae less bent and leas compressed. Should further 

 observation show these characters to be valueless the last mentioned 

 specific name will prevail. 



Mr. Schwarz collected at Selma, Alabama, a species of Myoditcs 

 parasitic on Nomia nevadensis Cresson. The abdomen is yellow in 

 the 9 and black in the % . [I have not yet seen this species but hope 

 to have an opportunity of doing so before long.] 



2. Habits. — Ernobius tenuicornis Lee. In boughs of Pinus rigida, 

 Mass., (Blanchard). 



Ptllinus hasalis Lee, in dead twigs and branches of Laurus, the
