men. The venation also differs, the veins forming the outer por- 

 tion of the submarginal cell are less sinuous, the anterior branch of 

 the third vein reaching the margin at the tip of the wing and not 

 before the tip. The fifth vein forming the posterior margin of the 

 discal cell is also less curved. The brown extends slightly further 

 into the first and fourth posterior cells giving the margin a trilobed 

 appearance. 



Villa bigradata (Loew). 



Anthrax bigradata Loew, Cent., viii, 37, 1869. 



Aspecimen from Muskeget Island, Mass., June 18, 1913, collected 

 by Dr. G. M. Allen, and a specimen from Provincetown, Mass., 

 June 13 (Webber), can only be referred to this West Indian species. 

 Coquillett records it from Califronia. This distribution is interest- 

 ing, though not unusual as several members of this family have a 

 similar or much wider distribution. 



SYNCHRONOUS MOVEMENTS IN VANESSA ANTIOPA 

 LARV^, WITH NOTES ON THE ATTRACTION OF 

 CERTAIN MALE LEPIDOPTERA BY THE FEMALES 

 OF THEIR OWN SPECIES. 



By Fred H. Walker, 

 Salem, Mass. 



About the middle of last April, while taking my regular Sunday 

 morning walk along a favorite woodland path, I saw a Vanessa 

 antiopa depositing her eggs on a willow sapling. I broke off the 

 twig with the eggs attached, carried them home and placed them 

 in a breeding cage. The larvae appeared in 17 to 18 days, went 

 through the regular course of feeding and moulting and the latter 

 part of May developed into a fine brood of over one hun- 

 dred full-grown caterpillars. One evening a few days before 

 pupation began, the cages (the colony had been divided and now 

 occupied two cages) were brought out to the light for the purpose 

 of putting in fresh food for the occupants, one cage being set on 

 top of the other. The cages were partially filled with small willow 

 branches, and the caterpillars were scattered all over the cages, 

 some on the top and sides and others on the leaves and branches.
