Apion nigrum sometimes depredates the leaves of locust (Robinia 

 pseudacacia). A. fraternum was observed upon two species of Lespedeza 

 by Mr. F. H. Chittenden. A. segnipes was obtained from the seeds of a 

 species oi Astragalus by Say. (Le Conte, Ed., p. 265.) 



Fodapion gallicola makes a spherical or ovoid gall on pine (Pinus 

 inops), Riley. (Bull. Bklyn. Ent. Soc, Vl., p. 61.) I have also found 

 the galls in the vicinity of Washington, D. C, last June. 



Phyto7iomus punctatus lives on the leaves of clover. I have found it 

 in abundance on timothy grass this season. P. nigrirostris also feeds on 

 clover and Buphthalinum Salicifolium. P. comptus lives on Polygonum, 

 and P. eximius on Rumex. (Riley, Rep. Dept. Agricul., 1881-82, p. 171.) 



Listronotus latiusculus was found by Mr. C. M. Weed in all stages in 

 the stalks of Sagittaria variabilis. Mr. F. M. Chittenden found L. 

 tuberosus, L. caudatus and L. appeiidimlaUis while sweeping a small patch 

 of aquatic plants composed entirely of Sagittaria and a species of 

 Carex. L. appe?idiculatus, it is said, was found by Mr. William Julich 

 breeding in the lower parts of the stems of some species of reed. I 

 have also taken two species of Listronotus on the flower heads of 

 Sagittaria at Shingle Creek, Kissimmee, Florida, April. 



Pissodes strobi is sometimes very destructive to the white pine. The 

 larva and imago were first figured by Peck, in 181 7. (Mass. Agricul. 

 Reposit, IV., pp. 205, 211, pi. I.) P. affinis is also found on the pine. 



Pachylobius picivorus is placed by Mr. W. H. Harrington in a list of 

 insects found on pine (Trans. Ottawa Field Nat. Club, I, p. 33). 



Hylobius pales lives in pine trees beneath the bark, burrowing into 

 and destroying the inner surface of the bark, and the tender newly 

 formed wood, often doing great damage to pine forests. 



Lixus rubellus has been observed in considerable numbers clinging to 

 the leaves and blossoms oi Polygonum amphibium. (Webster, 1. c.) 



Lixus parcus is said by Dr, Riley to form galls in the stems of 

 Amelanchier. (Proc. Ent. Soc, Wash., I., p. 33.) 



Lixus concavjis. Glover has observed this insect burrowing in the foot 

 stalks of rhubarb or pie plant. (Rep. Com. Agri., p. 90, 1865.) I have 

 also found it on a species of Rumex, and also producing a gall in the 

 stalk of the thistle, from which I raised the species. Mr. Webster also bred 

 it from wild sunflowers. (Ent. Am., V,, p. 11.) 



Lixus macer. Dr. Riley reared this species from Chenopodium
