To these I will advert before proceeding further : — 



Semasia ohscurana, Steph. {ante p. 145). — I now find that Pcedisca 

 ohscurana, H.-S., which I supposed to be another species, is certainly 

 this insect, and was probably figured from one of Mr. Doubleday's 

 specimens. Nevertheless, Dr. Wocke places it next to trigeminnna, 

 and gives only Austria as its locality. 



Stigmonota Weirana, Doug, {ante p. 147). — I have seen many 

 more specimens of this species in London collections, and am now 

 convinced of its distinctness from nitidana, Steph. ; but as the 

 " further information " which I asked for seems likely to be forth- 

 coming next summer, further particulars must be deferred for the 

 present. 



Stigmonota orohana, Tr. {ante p. 148). — I omitted to notice tliat 

 "Wilkinson's figure 2, plate 2, although called dorsnna, really repre- 

 sents this species. His description would include both. 



Asthenia coniferana, Etzb. — Mr. Sang (Intellig. No. 192) states that 

 he has bred this species from dull yellowish, spotless larvfe, with pale 

 brown heads, feeding in the bark of Scotch fir, and expelling their 

 frass through holes in the outer bark. 



Asthenia cognatana.'s^. oi. 



Head, antennse, palpi and thorax dark grey. Fore--n'ings glossy, dark brownish- 

 grey, with silvery markings, consisting of a triangular dorsal blotch — curved out- 

 wards at the apes, and broad at the base, enclosing a triangular brown spot — and 

 five very oblique geminated costal streaks, the second being produced into a narrow 

 fascia or line, which, passing down the anterior margin of the ocellus, bends beneath 

 it towards the anal angle. Ocellus barred with alternate black and silvery lines, 

 much obscured by yellowish scales. Cilia dark grey, with two or three silvery spots. 

 Hind-wings brownish-grey. Alar. exp. 6 lines. 



Closely allied to coniferana, Etzb., and hitherto confounded with 

 it, but distinguishable by the greater breadth of its fore-wings, the 

 broader and more curved dorsal blotch, the far more oblique costal 

 streaks, and the outward curvature of the delicate silvery fascia, 

 which, in coniferana, bends inwards towards the dorsal blotch. It is 

 also a larger insect. 



This species seems to be in very few collections. Some years 

 ago I received specimens from Scotland under the name of coniferana, 

 but more recently meeting with true specimens of that species in 

 Hampshire and Norfolk, was struck with their distinct appearance ;
