Argyresthia farinatella, Zeller, Isis, 1839, S. 206, 20. Linn. Ent. ii. 296. 

 CEcophora farinatella, F-v-B., pi. 74, f. 4, S. 211. Dup. xi. 473, pi. 305, f. 11. 

 Telea subfasciella, Steph. Illust. iv. 247 ? 



Expansion of the wings 4 — 5 lines. Head whitish, intermingled with gray hairs. 

 Face whitish gray. Palpi whitish. Antennae whitish, with dark brown annulations. 

 Thorax grayish. Abdomen fuscous. Legs white. Tarsi white, with black annula- 

 tions. Anterior wings grayish, with somewhat of a brownish purple tinge ; rather be- 

 fore the middle of the wing is a well-defined white fascia, the inner margin of which 

 is the darkest portion of the disk ; towards the apex is an appearance of another fas- 

 cia, or more frequently of two pale opposite spots, on the outer margins of which are 

 several black scales ; the inner-marginal half of the base of the wing is generally paler 

 than the costal half: cilia pale gray, with two rows of black dots round the apex to 

 the anal angle. Posterior wings grayish, with paler cilia. 



Closely allied to the preceding, but at once distinguished by the absence of the 

 golden fascia at the base, by the narrower anterior and posterior wings, by the darker 

 colour of the ante-medial fascia, and the darker apical portion of the anterior wings, 

 which thus renders the pale fascia far more prominent in this species. 



Not an uncommon species among fir-trees, in June and July, and apparently 

 widely distributed. I have taken it in plenty at West Wickham, Surrey, and in Tor- 

 wood, Stirlingshire. 



Zeller states that it occurs " on firs ; generally in company with Gysseleniella." 



The genus Ocnerostoma, Zeller, contains but one species, which differs but 

 slightly from the concolorous Argyresthia?, the essential characters of the genus being 

 the extreme shortness of the palpi and a different neuration of the wings : this spe- 

 cies is — 



piniariella, Zeller.

 CEcophora galactitella, Eversm. F. V. U. 525, 4. 

 Porrectaria laricella, Thomson, Zool. 



Expansion of the wings 4 — 4f lines. Head grayish white. Face grayish white. 

 Palpi gray, almost concealed in the hairs of the head. Antennae gray, concolorous. 

 Thorax grayish white. Abdomen fuscous. Legs whitish. Tarsi whitish. Anterior 

 wings silvery gray, concolorous : cilia pale gray, not glossy. Posterior wings pale 

 griseous, with paler cilia. 



The colour of the anterior wings varies considerably, being sometimes nearly white. 



This insect differs from Argyresthia amiantella in having a gray head, and not a 

 yellow one, and in the much shorter palpi. Coleophora laricella,* for which this 



* Coleophora (Astyages) laricella of Hubner was first detected in this country 

 this summer, by Mr. Bedell, who observed it flying in swarms round the boughs of
