THE CANADIAN ENTOMOLOGIST. 235 



entire existence, has the habit of frequently turning and shaking itself so 

 as to produce a rattling noise, which has given it the popular name of 

 "campanita" (little bell); on opening one side of the cocoon the large 

 head of the larva or the front portion of the pupa may be seen in rapid 

 vibration striking the walls of its chamber. 



In several dozens of these cocoons I can observe no variation in the 

 plan. No parasites noticed. Am ready to furnish specimens to those 

 who desire a real " butterfly cocoon." 



On page 397 it is remarked that " we believe they (Hepialidae) never 

 fly to light." I have taken F/iassus triaiigiilaris, H. Edw. ; P. argent i/erus 

 Walk., and a species of Hepiahcs at light, though rarely. As the body of 

 Phassus is commonly 65 mm. in length, and the wings proportionately 

 narrow and clumsy, I would suggest that the large Hepialids may venture 

 on only short flights. 



The eggs of Phassus triangularis are minute (0.3-0.5 mm.), very 

 numerous, and of a gray or blue colour at first, turning to brown or 

 black ; and since they appear to be devoid of any glutinous coating, it is 

 probable that the female merely drops them among the underbrush, 

 trusting in the safety of numbers. 



Under the new family Eupterotidas (p. 376), the author touches on 

 the irritating properties of the larval hairs, and on the habit of nest- 

 building. The hairs of ATetanastria psidii, Salle', are barbed at the tip 

 and very irritating, in the same way as \hosQ o{ Haiisidota propinqua, H. 

 Edw., but contain no poison. The nests of this Eupterotid on Qiiercus 

 jalapcnsis are conspicuous objects in some districts, being frequently 3 to 

 5 feet in length. No true cocoon is made, the larva pupating in a suitable 

 space in the home nest. The larva is nocturnal in habits, and yet it is 

 parasitised by an Ichneumon. 



Under the Saturniidi« (p. 372), Dr. Sharp mentions the ocellate 

 marks on the secondaries of species of the genus Automeris. It appears 

 that these markings have a protective value, as all the species with which 

 I am acquainted have the habit, when disturbed, of raising the primaries 

 (so as to expose the large glaring " eyes "), and holding the secondaries 

 at " present arms " until the fright is over. 



The cocoon of at least several species o\ Automeris has a quasi-hinged 

 grating in its front portion, which opens only outwardly ; the front is closed, 

 but with very weak (brittle) silk,
