 FOOD HABITS OF SOME CHRYSOMELIDiE. 



BY WM. BEUTEMMULLER. 



Donacia. — The \arious species of this g-enus occur upon the 

 leaves of aquatic plants, especially water-lilies {Nymphcea and Nu- 

 phar). I have taken D. palinata, D. piscatrix, D. siLbtilis, D. 

 fevwrata, D. (xqiuiHs and D. flavipes upon these plants. No lan-a 

 of any American species has yet been described; they undoubtedly 

 have the same habits as the European species which bore in the 

 stems of water-lilies. 



Lciiia bninnicollis and L. collar is. — Both these species live on 

 the thistle; the former I have taken at Enterprise, Fla., and the 

 latter species was bred by Coquillett (Can. Ent. xv, p. 22). 



Lema sola?ii and Z,. conjiincta I have found upon the leaves of 

 Solaniim carolmense at Enterprise, Fla., in May. 



Lema trilineata li\-es upon Dahira stramoniiun, potato and 

 Physalis. 



Crioceris asparagi and C. 13-punclata both feed upon the lea\'es 

 of asparagus. 



Cosdnoptera dominicana lives in a case on sumac (Harris' Corr. 

 p. 76;. The insect has also been beaten from oak, apple, plum 

 and sassafras (Riley, 6th Mo. Rep. p. 127). 



Chlamys plicata. — I have bred this case bearer from the leaA-es 

 of blackberry and hazel; also found on sycamore and oak. 



Exema gibber and E. conspcrsa. — I raised these two species 

 from a narrow leaved species of aster. 



Cryptocephahis cf.-maailatHS is found on oak. C. biyiomis I have 

 taken on blackberry in Florida. C. venustus also inhabits the 

 blackberry. C. aidicus occurs upon a small leaved huckleberry in 

 Florida, as also does Gribiirizcs larvahts. 



Pachybrachys tridens feeds on poison ivy {Rhus toxicodendr oil). 

 P. luridus may be found on wild indigo {Baptisia tindoria). P. 

 livens inhabits the willow. P. feniorahis has been taken on pine 

 by Mr. Harrington (Can. Ent. xvi, p. 97). 



Bassareus fonnosics lives on \-arious species of alder. B. 

 mamvii/er may be found on blackberry. 



Glyptocelis piibescens. — I ha\e taken this species at F"ordham, 

 N. Y. . on hemlock; also found on pine (Fitch). 



Chrysocluis auratus occurs in considerable numbers upon the 

 leaves of dog-bane {Apocy 712cm). The lar\^a of this common species 

 has not yet been recorded. I have searched for it in vain upon the 

 leaves of the plant the imago infests. Can the larva, perhaps, in 

 some way live upon the roots ?
