Agelastica halensis lives in Galium veriim in Europe. No 

 record of its food-plants in this country has as yet been made. 



Diabrotica vittata iwres in the stems and roots of pumpkin and 

 squash vines. D. longicornis feeds on the roots of corn (Forbes, 

 2d Rep. Nox. Ins. 111. p. 55). 



Trirhabda brevkoUis. — I have taken this insect in abundance 

 on prickly ash at Kissimmee, Fla. April. 



Trirhabda tomentosa lives on various species of golden rod and 

 asters (BeutenmuUer, Can. Ent. xxii, p. 36). 



Galeruca xanthomelcena. — This insect infests the elm, blighting 

 the leaves and rendering almost worthless the trees they attacked. 

 The pest within the last three or four years has made its appearance 

 in considerable numbers in New York City, and is doing great mis- 

 chief to the trees of our avenues and parks. 



Galeruca marginella lives on Myrica gale (Packard Guide, p. 



505)- 



Galeruca sagittaricB may be found in June and July in its va- 

 rious stages on the leaves of water-lilies {Nuphar') and Sagittarice.

 species of grass found behind the sand-dunes along the sea-shore of 

 Long Island. 



Blepharida rhois feeds on sumac (Riley, 6th Mo. Rep. p. 118- 

 122). 



Disonycha limbicollis, D. pallipes, D. pmictigera, D. pennsyl- 

 vanica and D. rtifa ? — I found all these on various species of Poly- 

 gomcm. The larvae undoubtedly also live in some way upon this 

 plant. - D. collaris was bred by Miss Murtfeldt, from the leaves of 

 Spinach and Chenopodiuvi albuvi (Bull. No. 22, U. S. Div. Ent. p. 

 76). 



Haltica chalybea lives on elm and grape. H. bi^narginata in- 

 fests the alder (Lintner, 4th Rep. Nox. Ins. p. 98). H. foliacea 

 feeds on apple and hawthorn (Murtfeldt, Insect Life, i, p. 74-76). 

 H. marevagans I have bred from evening primrose. 



Crepidodera cucumcris is found in numbers on the leaves of cu- 

 cumber, potato and Datura straDwniuvi. C. helxines live on willow 

 and poplar. 



C. rufipes was taken by Lintner on apple. I found it on locust 

 last May at Washington, D. C. 



Phyllotreia vittata may be found on cabbage and other crucifer- 

 ous plants. P. zimmermanii mines the leaves of peppergrass (Riley, 

 Rep. U. S. Dept. Agric. p. 304, 1884). P. chalybeipennis mines
