return and breed among the ants, or whether it is a new brood that claims 

 their hospitality for the winter, is absolutely unknown. I never could 

 satisfy myself as to whether those found in the nests in June had returned 

 or were just preparing to leave. (For some interesting observations on 

 this species and Schaumii see Ent. Am., i, 187.) 



C. Harrisii Kirby. I neglected to observe the ant with which I 

 took a specimen. 



Dr. Horn incidently mentions that C. latcosticticus, pilosicollis and 

 castanece have likewise been observed in ants' nests. (Pr. Am. Phil. 

 Soc, 18, 384.) 



Without much doubt many species of our Staphylinidce will be found 

 to be Myrmophilous as in Europe, where, according to Rev. J. G. Wood, 

 in the Aleocharidse alone no less than " eight genera contain species that 

 are parasitic and spend their whole lives in the nests of ants," among 

 them Atemeles emarginatus and A. paradoxus living with Formica fusca 

 and Myrmice ruginodis which take as good care of them as of their own 

 young ; also Myrmedona Hazvorthii and Dinarda dentata, Quedius 

 brevis is said to live with Formica rufa, and that wonderful beetle 

 Claviger foveolatus, destitute of eyes and mouth, inhabits with Formica 

 flava. 



Besides the species catalogued here several others in our Fauna are 

 traditionally reputed to dwell with ants, but the observers have either not 

 published the facts or I have failed to find the bibliography. 



THE CLASSIFICATION OF THE BOMBYCID.E. 



(Second Paper. ) 



BY A. R. GROTE, A. M., BREMEN, GERMANY. 



We have seen, Can. Ent., xix., p. 156, et sea., that the Bombycida?, or 

 Spinner Moths, are characterized, as a whole, by their short, pectinate 

 antennre, ample, velvety wings, thick bodies, small heads and sluggish 

 habit, while the pupa is usually contained in a cocoon made by the cater- 

 pillar in its last stage. To almost all these characters the sub-.amily 

 groups offer exceptions, and we have seen that while Dr. Packard follows 

 the tradition of Harris, Latreille and Linnaeus, modern German writers 

 break up the family into independent groups limited by structural features
