Hoplothrips magnafemoralis Hinds (=Acanthothrips magna- 

 femoralis Hinds). In the top of a fallen maple tree. Cranberry 

 Lake, N. Y., July, 1920. C. J. Drake, Coll. 



Hoplothrips corticis Serville {=: Acanthothrips nodicornis Reu- 

 ter). With the last. 



There seems to be no published description of the larvae of 

 these species. The larvae of both species are bright red, but 

 those of corticis are a deeper red. In this species the color ex- 

 tends into the legs, except the tarsi, the entire tube, and even the 

 first and second antennal segments. In magnafemoralis there is 

 much less red pigment in the head, little in the legs and that mostly 

 in the coxae, and the last abdominal segment is free of red pigment ; 

 the second abdominal segment is lighter in color, often distinctly 

 yellow, and forms a conspicuous band. In this species the ante- 

 rior angles of the head are produced over and between the bases 

 of the antennae and the eyes into striking horns which consider- 

 ably exceed the first antennal segment. These horns are curved 

 and incompletely divided by a constriction near the middle. From 

 the apex of the basal section arises a large, colorless, blunt bristle 

 which extends beyond the horn. This horn-like extension is ab- 

 sent from the larvae of corticis. 



FOODPLANT OF LUPERINA PASSER GN. (LEPIDOPTERA). 



By George P. Engelhardt, Museum, Brooklyn, N. Y. 



It appears that nothing has been published regarding the food- 

 plant and habits of this rather common moth. 



The larva is a borer in the roots of Rumex verticillatus and 

 probably other species of this group of plants. It hibernates 

 within its gallery, continues feeding for a short time in the spring 

 and attains full growth (i^ inches) early in May. The head, 

 neck- and anal-shields are chestnut brown; otherwise it is dull 

 white. When ready to pupate, the larva leaves its burrow to con- 

 struct a slight cocoon within the adjoining soil. The pupa is 

 glossy, light brown. One imago, female, obtained out of three
