AMERICAN ENTOMOLOGY. 95 



Desc. Body above rufous, punctured ; head narrowed before, 

 and rounded at tip; antennae rufous, basal joint yellow, terminal 

 joint fuscous : thorax with the posterior angles obtusely rounded : 

 scutel [with numerous, very short, transverse black lines; a 

 transverse, slightly raised elliptical line at base, from which pro- 

 ceeds a slightly carinated longitudinal line, becoming obsolete 

 on the middle : tip very slightly emarginate : hemelytra, on the 

 coriaceous portion marked by the same minute lines as the 

 scutel : tergum margined with alternating black, quadrate spots ; 

 beneath yellow : feet simple, rufous : venter with two almost ob- 

 solete black lines gradually approaching each other to the penul- 

 timate segment where they terminate in a common black spot. 



Obs. This species inhabits the Middle States, but it does not 

 occur very frequently.

PHRYGANEA. Plate XLIV. 



Generic character. Antennae as long as the body, with nu- 

 merous joints; stemmata two; mandibles none; palpi rather 

 long : inferior wings larger than the others, longitudinally 

 folded ; feet elongated, spinous : tarsi elongated, five-jointed, ter- 

 minal joint with two small nails ; abdomen destitute of filaments 

 at tip of the tail. 



Obs. The greater number of these insects venture forth upon 

 the wing during the evening and night, and when disturbed in 

 their resting place in the day, they fly a short distance, and 

 again seek a place of concealment and safety. They frequently 

 enter our houses in the evening, attracted by the light of a can- 

 dle, around which they fly. The larva lives in the water, and 

 the parents are therefore generally in its vicinity. Some spe- 

 cies swarm in large flocks, whilst others are solitary. They are 

 light and active, and run with much swiftness. When the fe- 

 male is about to deposite her eggs, she ejects a considerable 

 number of them, which remain attached together at the extrem- 

 ity of her abdomen ; these she places in a favorable situation, on 

 the stalk or leaf of a water-plant, or other object, from which the 

 young larva may readily pass into the water. Here it soon be- 

 gins to fabricate a tubular, portable dwelling, which, as respects 

 form, may be compared to that of the clothes-moth. This domi-
