Hemerobius moestus Banks. 



Hemerobius mcestns Banks, Trans. Am. Ent. Soc., xxiv, p. 25, Febru 

 ary, 1897. 



Kaslo, 16 June to 8 July, three specimens. 



The specimen collected on June 16 seems to be in the teneral 

 condition, the wing markings being indistinct. The wings 

 in this specimen are somewhat broader than in the two others.

Kalso, 2 and 24 July, two specimens. 



In view of the fact that H. pacificus has been considered as 

 possibly a western form of this species, it is somewhat of a surprise 

 to find in our collection examples of what appear to be typi 

 cal castanece. The ten specimens of pacificus collected in Brit 

 ish Columbia show no gradation toward castanece and indications 

 are that these two forms are distinct species.
