Orchestes fiiger and O. subhirtus are both found on willow when in 

 bloom. (Harrington Can. Ent. i6, p. 119.) 



Orchestes niger and O. pallicornis were taken together in July on the 

 leaves of low willows by Mr. Chittenden. O. ephippiatus was found in 

 abundance on willow (Salix fragilis) by Mr. C. W. Leng and myself on 

 Staten Island, N. Y. 



Miarus hispidulus has been observed to breed in the seed capsules of 

 Lobelia inflata. Blanchard (Ent. Am. IL, p 87). 



Clonus scrophularlce attacks the fruit of the plum, feeding in the kernel. 

 The first mention and figure was given by De Geer in 1775 (Mem. V). In 

 Europe it is found on Scrophularla and Verbascum. 



Gymnetron teter may be found in abundance on the stalk of mullen 

 f Verbascum Thapsus.) The larva lives in the seed pods. 



Rhyssematus llneaticollls may be found infesting the seed pods of 

 milkweed (Ascleplas.) 



Tyloderma fragrarice lives in the strawberry, excavating the crown 

 and roots of the plant. (Riley.) 



Tyloderma faveolatum bores in the stems of evening primrose ( CEn- 

 othera biennis). Also bred from Epilobium by Dr. C. M. Weed. 



Cryptorhynchus lapathihoxQS in the stems of willow and alder. 



Cryptor/iynchus bisignatus was found by Dr. Packard on the leaves of 

 oak. Several specimens were taken by Mr. F. H. Chittenden in the latter 

 part of May at Clifton, N. J., on a chestnut log infested with Leptostylus 

 macula, and during the last part of June fifteen or sixteen examples were 

 found on another log of chestnut, some of them copulating ; also taken 

 on the trunk of a living birch tree infested with Scolytids. 



Cryptorhyiichus parochus lives under the bark of butternut. (Schaupp, 

 Bull. Bklyn. Ent. Soc, IV., p. 35.) 



Pseudomus truncatus is found on dead limbs of old butternut trees, 

 according to Mr. Harrington. (Can. Ent., 16, p. 118.)
