INSECTS INJURIOUS TO THE SUMACH. 



Rhus glabra. 



1. Gelechia rhoifructella Clem.* 



Order Lepidoptera; family Tineid^. 



The larvse may be found in April, or early in May, in the fruit spikes of 

 sumach {Rhus typhina)^ where they feed on the crimson hairs and ex- 

 terior envelope of the drupes, without, however, eating the drupes them- 

 selves. The larv.neare concealed in galleries formed in the fruit spikes, 

 and tlieir presence is indicated by strings of "frass" clinging to the ex- 

 terior. The cocoon is a slight silken web woven among the "frass" 

 near the surface. The imago appears about the middle of June. 



Larva. — The larva is immaculate, aud varies in color, from dark reddish-brown to 

 a pale brown, dotted with rows of darker-colored dots, each giving rise to a hair; 

 the head is brown aud the shield blackish. 



Moth. — Head, face and thorax grayish-fuscous. Labial palpi rather dark ocherous. 

 AuteunsB ocherous, annulated with black. Forowiugs grayish-fuscous, dusted with 

 dark browu, and with four dark fuscous dots, one near the base of the fold, two near 

 the middle of the wing (oue on the fold and one above it), and one ou the end of the 

 disk. Near the end of the wiug is an indistinct grayish band. Hind wings fuscous, 

 cilia the same. (Clemens.) 



* Of this I received three specimens from Dr. Clemens ; it has considerable resem- 

 blance with our G. popidella, but the anterior wings are broader and blunter, and 

 the anterior segments of the abdomen are not pale. The exp. al. is 8 lines. H. T.
