THE CANADIAN ENTOMOLOGIST, 371 



Pupa about 680 //. long, white, slightly suffused with ochraceous 

 dorsally, especially the operculum, or with a distinct suffused orange 

 patch ; sides vertical, striate, margin minutely crenulate ; a pair of short 

 caudal filaments ; fringe consisting of a series of curled, glassy transparent 

 rods, about 8c-ioo/x long, very easily deciduous, and always inconspicu- 

 ous, so that an old pupa seems to be without a fringe \ vasiform orifice 

 normal, emarginate at apex, about 52 /x long ; operculum very broad and 

 low, about half length of vasiform orifice ; lingua broad and rounded, with 

 one notch on each side of the portion projecting beyond the operculum, 

 and the usual apical bristles ; in the subdorsal region there is on each side 

 a series (one to each segment) of large round pores, practically as in A. 

 iridescens, but beyond these, near the margin, are numerous irregularly- 

 placed smaller circular hyahne pores, resembling the subdorsal pores of 

 A. glacialis. The structure of the vasiform orifice and appendages is 

 nearly as in A. spineoides, excei)t that in the latter the apex of the orifice 

 is entire, and the bristles of the lingua project. In the last-mentioned 

 characters the new species resembles A. Waldeni. The spotted wings 

 recall those of ^. Fitchi.

NOTE ON PLATEROS COCCimCOLLIS FALL. 

 This species is described by Fall in Trans. Amer. Ent. Soc, June, 

 1910, p. 139. The type is the Phiteros, sp. nov., of the New Mexico list. 

 Trans. Amer. Ent. Soc, June, 1907, p. 181. Mr. Fall also cites "Boulder, 

 Colorado," but the specimen referred to was collected by myself in 

 Boulder Canon, Sept, 1907, at 7.340 ft. altitude, Tenebrioides occide/italis 

 Fall, t. c, p. 128, is the T. sp dub. of the New Mexico list.

LEPIDOPTEROUS GALLS ON SPECIES OF SOLIDAGO. 



BY A. COSENS, TORONTO, ONT. 



A great deal of the work done in the science of cecidology has been 

 accomplished by observers who have been more interested in the ento- 

 mological than in the botanical aspect of the subject. As a consequence 

 of this, the host-plants affected by the various galls, in many cases, have 

 not been specifically determined. The fact, however, that each gall is 

 restricted to certain species of host-plants makes this side of the science 

 an interesting and important one.
