Exhibit C. 1 cocoon. Silk spun up leaf stalk, but insecurely attached 

 to brancli, only two threads had been spun out to the normal distance, but 

 the fact of the leafstem being completely surrounded with a casing of silk 

 which extends up to the branch, shews an evident intention of securing it 

 against falling. 



Exhibit D. 2 cocoons. Spun between folded leaves without any ap- 

 parent intention of securing them from falling. 



Fig. 12. Telea polyphemus cocoon spun 

 between leaves. 



The results thus obtained show that out of twenty cocoons, eighteen 

 had in some way made provision against falling to the ground, and, whilst 

 an inspection of the cocoons sent will shew that many of them are so firmly 

 attached to the branch that a woodpecker would find little trouble in pierc- 

 ing them, yet, the characteristic protection of the group would seem to 

 point to some other cause than that assigned by my correspondents, and 

 after having seen the result of my experiments to determine whether the 

 suspension was accidental or premeditated. I can only reiterate my sug- 

 gestion in Canadian Entomologist of April last, that this protection is 

 mainly against climatic change, and their consequent destruction by wet, 

 and is governed by the local climatic conditions. 



Exhibit E. 1 Imago. Emerged 22nd August, another emerged two days 

 later. 



In conclusion, I would draw your attention to the paragraph dealing 

 with this species by Dr. H. G. Dyar, Proc. National Mus. Vol. xxvii, 1,376, 

 page 792, in which Dr. H. G. Dyar characterizes this moth as having a 

 tendency to a distinctly local race, and in addition to the variation in colour 

 mentioned by him it may be added that the submarginal band on the 

 primaries is almost straight, and not curved as in the case of eastern and 

 southern specimens, the wing being more angular than the falcate form 

 of the eastern States, but at the same time not being sufficiently different to 

 warrant a varietal name. 



INSECT NAMES/ AND INSECT LISTS. 



By J. B. Williams, F.L.S., Toronto. 



Some time ago the British Museum received a pair of giraffe skins from 

 East Africa. They were mounted for the museum, and it became neces- 

 sary to identify the exact variety of giraffe to which they belonged, so Dr. 

 Lydekker wrote a paper revising the species and subspecies of giraffe all 

 over Africa, "and without," he says, "any desire to add to the burden of 

 zoological nomenclature," he came to the conclusion that the right scienti- 

 fic name of these museum specimens was Giraffa cameloyardalis I'othschildi; 

 or the "Baringo Giraffe."
