Conotrachelus naso has been bred from the fruit of hawthorn (Cra- 

 tcegus) by Dr. Hamilton. (Can. Ent., 21, p. 34.) C. cratcegi also lives 

 in the fruit of the Cratcegus as well as that of the plum. 



Conotrachelus nenuphar is destructive to the apple, apricot, cherry, 

 peach, pear and quince, feeding in the fruit. C. juglandis inhabits walnuts. 



Conotrachelus anaglypticus, according to Say, breeds in the fruit of the 

 walnut (/uglafis). C. elegafis was obtained by Say on Finus rigida, 

 (Leconte Ed. I., p. 283.) 



Crapojiius incequalis is destructive to the grape, stinging the fruit and 

 sometimes destroying the whole bunch. 



Rhinojicus pyrrhopus. A pair of these little beetles were taken by 

 Mr. F. H. Chittenden in coitu on a common species of dock (Rumex sp.), 

 and being confined in a small vial with a part of a* dock leaf consumed it 

 almost entirely within a week. The species has also been observed by 

 Mr. M. L. Linell on a species of Ru?fiex. June. 



Coeliodes flavicaudis, according to Mr. Chittenden, occurs in great 

 abundance on the common nettle (Urtica dioica) in May, June and July. 



C. acephalus is abundant along the coast of New Jersey on the evening 

 primrose (CEnothera biennis). June, July and August. 



Acoptus suturalis Lee. lives in the dead wood of beech trees. Mr. F. 

 H. Chittenden has found the imagines in the wood March 27th to April 

 20th in company with larvae apparently of the same species. One of these 

 larvae taken May 26th appeared about to pupate. The beetles were 

 crawling on the trunk of the tree early in July. 



Monojiychus vulpeculus infests the seed pods of the blue-flag (Iris). 

 It also occurs on the flowers of Ceanothus americanus and Verbascum 

 thapsus. (Say, Vol. I. Lee. Ed., p. 286.) 



Ceutorhynchus cyanipennis. According to Mr. Jlilich this insect is 

 said to be found on grass (Ent. Am., 5, p. 57). In Europe it lives in the 

 roots of cabbage. 



Ceutorhync/ms assiinilis occurs on the radish and C. rapce infests the 

 rape, and C. septentrionalis is found on mustard (Sisymbrium officinale).
