1924. Maine Agr. Exp, Sta. Bull, 319, p. 137. (Gives only the locality and 

 food plant of larva; no description or figures, and the vprlter says (p, 

 138) that he does not know the seasonal history of the species.) 



GALERUCELLA CRIBRATA LeConte 



(U. S. Nat. Mus. ; larva describetl from vials marked: "On Solidago altis- 

 sima, Springfield, Mass. Dimmock No. 1685." — Material contains: (1) 

 Pyriform, brownish-ochreous eggs, 1 mm. long by 0.7 mm. in diameter, 

 with surface consisting of regular hexagons with depressions in the 

 middle; eggs deposited in large number from July 12 to 22, 1890, in 

 groups of 1 to 12 in a place near the base of the root leaves of the food 

 plant, sometimes on the upper surface, sometimes on the lower. In 

 hatching the larva eats away the small, upper, free end of the egg, 

 leaving the large portion of the shell attached to the leaf (from notes 

 of Dimmock); (2) newly hatched larvae; (3) full-grown larvae — 

 1685a — taken July 15, 1900; (4) pupa and cocoon.) 



Mature larva. — About 7 mm. long. 



Head shining, light yellow to light brown, with light-brown 

 labrum. Body with membranous part greenish white, chitinous 

 parts creamy yellow, with the small tubercle-shaped setal cups 

 darker ; legs creamy yellow, with brown claws. 



Setae moderately long, most of them about half as long as a body 

 segment. 



The shape of the headcapsule, mandibles, and the other mouth 

 parts, the form of the prothoracic shield and the number of its setae, 

 the development and number of the mesothoracic and metathoracic 

 sclerites and the number of their setae, the abdominal sclerites and 

 their setae, the pygidial shield and tenth abdominal sclerite exactly 

 as in GaleruceUa notata; in fact, the two species can not be separated 

 in their larval stages by any structural characters. 



Habits. — Feeding on the leaves of different species of Solidago, 

 but, according to W. C. Woods, is seemingly confined to species of 

 the subgenus Virgaurea. Pupates in an oval cocoon formed by an 

 open network of filaments and attached to a leaf.
