§^ [September, 



spots separated by whitish scales. Fringes grey. On the under-side of the fore- 

 wings a pale costal spot indicates the upper end of the white waved outer line. 

 nind-xvings shining grey. 

 Abdomen slightly dai'ker than the hind-wings, anal tuft pale ochreous. 



This description is taken from two males, of which the expanse 

 of the wings is 8 lines. I have received from Mons. liagonot a speci- 

 men of the female from Germany, in which the expanse of the fore- 

 wings is 10 lines. 



Sufficient time has not yet elapsed to prove whether the larvae 

 collected in some of the aborted cones in which this Phi/cid has been 

 bred are really those of the same species, but I think there can be 

 little doubt of this, and, in any case, there should be no difficulty in 

 verifying the fact in due time. Several empty pupa cases have been 

 found enclosed in a light silken web surrounding the hollow interior 

 of the aborted cones. 



A description of a larva which is now feeding should be easily 

 recognised : — 



Head pale brown. 



Second segment with an undivided plate or shield slightly paler than the head ; 

 the anterior edge straight, posterior edge convex. On each side of the shield on the 

 same segment is a small reniform chitinous spot. 



The rem.aining segments semi-transparent, greyish-white. The dorsal vessel 

 dark grey. The 3rd and 4th segments are traversed by a transverse line of very pale 

 brown slightly tuberculated spots, three on each side of the centre, each of these 

 spots bearing a single delicate whitish hair. The penultimate segment with three 

 small, pale brown, chitinous spots, the middle one being the largest. The last 

 segment is almost completely covered above by a circular chitinous plate of a 

 brownish colour. Segments 5 to 11 have each four slightly tuberculated spots, ar- 

 ranged in the form of a square above, with two more at each side, one beneath the 

 other, opposite to the centre of the segment. 



Length, about 4^ lines, when apparently about half-grown. 



All the spots are very pale brown, each bearing a single hair.

P.S. — ^Since writing the above I have taken a fine female of Ca- 

 teremna terehrella, Zk., flying among common spruce firs, at a distance 

 from the place where I found the larvae. I have also found traces in 

 aborted cones on common spruce, of a larva feeding in the same 

 manner as those on Abies Douglasii. I am inclined to believe that G. 

 terehrella will be found to be widely distributed, and by no means 

 uncommon. — Atigusf IHth, 188G.
