THE INSECTS OF NEW JERSEY. 441 



A. nais Dm. Throughout the State, May to September. The larva is a 

 general feeder on low plants, and has been taken in Paterson (Gr). 

 May 10-19. 



A. vittata Fabr. Elizabeth VIII, 24 (Bz); 5-mile beach VI, and through- 

 out the State generally with the preceding. 



A. phalerata Harr. Plainfielcl V, 19 (Gr) ; 5-mile beach VIII, 3 (Haim). 

 and* in general with the two preceding. The three species last cited 

 commonly fly together and are almost equally abundant. With flown 

 specimens there is sometimes a question of identity; with good bred 

 material at hand the differences are obvious. 



AMMALO Wlk. 



A. tenera Hbn. (Cycnia) Paterson VI, 15, VIII. 25 (Gr), to 5-mile beach, 

 VIII. 22 (Haim) ; and quite common throughout the State. The larva 

 on dog-bane. 



A. eglenensis Clem. (Cycnia) Paterson V, 27, larvas VII, 31 and IX, 11 

 (Gr); Ft. Lee (Bt) ; Newark (Soc); Staten Island VI (Ds). Feeds 

 on milkweed and is two-brooded. 



EUCH/ETIAS Lyman. 



E. egle Dru. (Cycnia) Common all over the State; two-brooded; the 

 curiously tufted larva on milkweed; flies in June and again late July 

 and August. 



E. oregonensis Stretch. Still to be discovered in the State. 



PYGARCTIA Grt. 

 P. abdominalis Grt. Lakehurst, V, 29, VI, 13 (Ds) ; 2 specimens only. 



HALISIDOTA Hbn. 



H. tessellaris S. & A. Common throughout the State. The larva is a 

 general feeder, often a nuisance on shade trees in cities, sometimes 

 troublesome in gardens and frequently found on fruit trees, on which 

 it does no serious harm. 



H. maculata Harr. This is said to be rare near New York City (Bt), but 

 becomes more common northwardly. The larva feeds on willow, oak 

 and poplar. 



H. caryae Harr. Throughout the State. The larva occurs with that of 

 "tessellaris" and has much the same habits; it may be found as late as 

 October.
