112 THE CANADIAN ENTOMOLOGIST. 



This form is very closely allied to subalbaria^ Packard, but in my opinion 

 the two are quite distinct. 



They are, however, according to Dr. Dyar,*^ confused in the Hulst 

 collection, being there united under the name (not really applicable to either 

 of them) Eois aiiticaria^ Walker. 



3. If it is admitted that subalbaria, Packard, belongs to the genus 

 Diastictis, and 1 do not think there can be any doubt about the matter, 

 then the specific name will clash with that of the Diastictis subalbaria, 

 Hulst,' described from Colorado, and I therefore propose for that species 

 the name Diastictis Hidstiaria. I have seen specimens -of this species 

 determined by Hulst himself from Manitoba, and I presume they correctly 

 represent his species. I have similar specimens from Calgary, and I 

 believe that the species listed by Dr. Dyar* from Kaslo in error, as Deilinia 

 variolaria, is the same thing. 



4. Dr. Hulst described still another white Diastictis in his last paper^ 

 as CymatopJi07-a virgijialis. The description is very short and inadequate, 

 but it would seem to refer to a smaller insect, "expanse 22 mm.," and the 

 few details given do not apply accurately to the specimens I have placed 

 under Huhtiaria. At the same time I must admit that I have received 

 specimens from the Catskill Mountains (Dr. Pearsall), which were said to 

 have been identified by Hulst himself as virgitialis^ which I cannot 

 separate from those I have spoken of above. It is probable, however, 

 that the study of more abundant material, and a careful examination of 

 Hulst's actual types, may demonstrate that Huhtiaria and virgiiiialis are 

 distinct, though very closely allied. 



The species considered in this article should stand in our lists as 

 follows : 



Diastictis subalbaria. Pack., non Hulst, California. 

 " Matilda, Dyar, Col., B. C, Nevada. 

 " Hulstiaria, Taylor, Col., Manitoba, B. C. 



= subalbaria, Hulst, non Pack. 

 " virginalis, Hulst, Atlantic States. 



And the reference to subalbaria^ Pack., under Eois aniicaria^ Walker, 

 must be struck out.
