verified the observation and noted that he had observed similar 

 eating out of the pustules of Falsa Icn-costoma on peach twigs 

 by an unidentified insect. 



The Leiopus (Leiopus alpha Say. identified by Prof. H. C. 

 Fall who states "Is unquestionably like the specimen on the 

 label L. alpha in the Leconte collection.") which emerge much 

 later than the Otidocephalus and in considerably less numbers 

 is also mycophagous, eating the pustules in a similar manner to 

 Oti'doccplialus. This habit of Leiopus has been noted by Dr. 

 F. C. Craighead and others in relation to chestnut blight and 

 other fungi.

Baris interstitialis Say. Harrisburg, Pa. "Taken as adults from 

 the roots of Xanthinum stnonariitiii all winter." V. A. E. Daecke.

Conotrachelus juglandis Lee. "Known as the 'walnut curculio,' 

 occurring on walnut, butternut and hickory, the larvae breeding in 

 the green fruit," Blatchley and Leng. We are of the impression that 

 the record from hickory refers to another species. 



The fine paper 4 by W. E. Britton and H. B. Kirk was overlooked 

 by Blatchley and Leng. Here we find the species recorded as feed- 

 ing and living in the stems as well as the fruit of six species or 

 varieties of walnut. We wish to record the fact that we have ob- 

 served the same thing in Pennsylvania, the leaf stems of walnut and 

 butternut being attacked as well as the fruit. 



Contrachelus elegans Boheman. W. D. Pierce writes"' "Is a very 

 important enemy of nuts. In Texas the first generation breeds in the 

 petioles and new shoots of hickory. Later individuals are found in the 

 leaf galls of Phylloxera dcTastatrix on pecan. Still later in the season 

 the species is bred from the nuts of various species of Hicoria." 



In Pennsylvania, Long Island and Connecticut it has but one 

 generation as far as we have observed. The injury is confined 

 to the new growth and leaf stems ; we have not observed 

 infested nuts.
