Arctiidae 



Form pallida Packard, Plate XV, Fig. 26, $, . 



The hvvx are social in their habits, and spin great webs upon 

 the foliage of almost all kinds of deciduous trees in the late 

 summer and fall, and do a great deal of damage to orchards and 

 nurseries. The insects pupate in loose cocoons, in crannies, 

 and even under the loose surface of the soil. The species ranges 

 over the United States from southern New England and New 

 York to Texas and further west. 



(2) Hyphantria textor Harris, Plate XVI, Fig. 9, $ . (The 

 Spotless Fall Web-worm Moth.) 



This species, which is closely allied to the preceding in its 

 habits, may be distinguished by the white antennae, and the un- 

 spotted abdomen. There are specimens of the preceding 

 species, which have the wings as immaculate as in H. textor. 

 The range of the insect is from Canada to the Gulf, and from 

 Nova Scotia to California. 



Genus ARACHNIS Gayer 



A small genus containing eight or nine species found in the 

 southwestern States of the American Union, Mexico, and Central 

 America. 



(i) Arachnis aulsea Geyer, Plate XVI, Fig. i, $, . (The 

 Aulaean Tiger-moth.) 



Syn. incarnata Walker. 



The insect occurs in southern Arizona and ranges thence 

 southwardly as far as Guatemala. The larval stages have been 

 described by Dyar in the Canadian Entomologist, Vol. XXVI, 

 p. 307. 



(2) Arachnis picta Packard, Plate XVI, Fig. 2, 3 . (The 

 Painted Arachnis.) 



Names have been applied to a number of color varieties of 

 this insect. It ranges from Colorado to southern California and 

 northern Mexico. The larva feeds upon Lupiniis. 



(3) Arachnis zuni Neumoegen, Plate XVi, Fig. 3, ? . (The 

 Zuni Tiger-moth.) 



The figure we give will enable the student to recognize this 

 pretty and rather rare species without any difficulty. It ranges 

 from New Mexico to Arizona and southward on the table- 

 lands.
