THE CANADIAN ENTOMOLOGIST. 101 



Many species no doubt pass the winter in the perfect state, but being 

 either buried deep in the ground or imbedded in the substance of trees 

 escape our notice, and as few entomologists are sufiftciently enthusiastic 

 to make large and deep excavations with so little prospect of return I 

 fear our knowledge of such as are included in the former category will 

 long remain incomplete. My own exertions at the wood pile have yielded 

 only bark beetles (and larvae) during the winter, though some evidently 

 spend this season more or less deeply imbedded in sound or decaying 

 wood. (See note by Mr. Blanchard, Can. Ent. VII:, p. 97.) 



Any comparison of such an incomplete list of our winter insects with 

 the forms known from the inhospitable climate of the far north would be 

 vain ; but I would remark the preponderance of Staphylinidse, as 

 suggestive, when taken in conjunction with the nature of the species of 

 the other families here noted, of at least an apparent similarity. 



CHIONOBAS UHLERI. 



BY T. D. A. COCKERELL, INSTITUTE OF JAMAICA. 



Mr. VV. H. Edwards, in his most interesting account of Chionobas 

 uh/eri, (Butt. N. A., PI. XII., Vol. 3) remarks that he can find no 

 evidence that it is found in the south of Colorado. It may, therefore, be 

 as well to record that I found it near Swift Creek, in Custer County ; and 

 Mr. H. W. Nash informed me that it occurred at Rosita, in the same 

 county. These localities are just north of 38° N. Lat. 



With regard to the variation in the ocelli of this and other Satyridee, 

 it becomes rather difficult to give statistics without the use of some regular 

 formula. Mr. Edwards gives the number of ocelli observed in different 

 individuals, but we are left in doubt as to which particular ones were 

 present, and which absent. 



A convenient method of indicating the exact nature of these variations 

 is to have a series of figures corresponding to the interspaces, numbering 

 from above downwards. If a butterfly had fully developed pupilled ocelli 

 in all the interspaces, the formula would read P. (for primary) 1234567, 

 S. (for secondary) 1234567. When an ocellus was wanting, o might be
