iETHALOPTERA INTEXTATA Walker. 



Twent3'-iive specimens, April 18 (Mr. Cockle), 'irt (Mr. Cockle), 

 May 81, June 2, 9, and two from Mr. Cockle's collection, May 15. 



ECTROPIS CREPUSCULARIA Schiffermuller. 



Three specimens, June 1 . In collecting-, this species was confounded 

 with M.elanolopli'ni (■<nia(hiri(i^ so that the usual efforts to obtain eggs 

 were not made in this case, imich to my |)i'esent regret. 



LYCIA COGNATARIA Guenee. 



One specimen, August 1. J have described tlie lar\a in Life 

 Histories of North American (ieometridie, XL.'^' 



ERANNIS VANCOUVERENSIS Hulst. 



No specimens; one from Mr. Cockle's collection, October 14. I 

 have it also from Pullman. Washington (C. V. Piper). Hulst calls 

 this form K. dcfollana variety vanamverenxix; but I see no more 

 reason f(n' regarding it as a variet}' of the European defoliarid than 

 of the Eastern fiH(irl<i Harris. The fact is that all the American 

 forms of Eraniiifi are but slightly divergent geographical (>x})ressions 

 of the P^uropean one and will doubtless be tinally so listed. Yet, 

 pending the examination of a l;>rger series of all the forms, I will 

 temporarily regard the Northwestei-n form as specific. 



DYSCIA ORCIFERATA Walker. 



No specimens; one in Mr. Cockle's collection. July <>, 1J>(I1. 



SICYA MACULARIA Harris. 



Five specimens, July 14, 25, 81, September 1» (Field). 



THERINA LUGUBROSA Hulst. 



No specimens; on? from Mr. Cockle's collection labeled T. somni- 

 ar!a Hulst. However, it agrees well with Hulst's type of /it(/uh/'om 

 before me from Rossland. From xoinnlaria the form differs in being 

 much more densely strewn with the gray striga\ which are contluent 

 and dominate the coloration. T. sonnuarla has been shown to feed 

 on the oak in the larval state, a plant which does not grow at Kaslo. 

 Therefore, I judge that lugulyrom is really a distinct species.
