Insects. 1267 



during the present and two preceding years, I believe that a great 

 number of species yet remain to be discovered, even in our most fre- 

 quented districts, while in Scotland, Ireland, and many parts of 

 England, a Tortrix or a Tinea has scarcely been looked for. What may 

 be done in a new locality, let the collection made by Mr. Weaver in 

 Scotland this year, witness, — a collection of rarities, I suppose, never 

 before equalled in Britain by one person in one year. Having, there- 

 fore, searched the works of Hiibner, Duponchel, &c, without finding 

 more than two of the ten following species ; I have thought it better 

 to describe them, than to let them add to the mass that I believe a few 

 years will produce. I possess and know of several other apparently 

 new species, but as I have not searched the continental books to see if 

 they are there described, I have left them for the present. 



Family. — Tortricid^e, Stephens. 

 Cnephasia conspersana, Douglas. (Fig. 1). 



Expansion of wings 8 lines. Anterior wings luteous, sprinkled all 

 over with griseous atoms, and a very slight trace of a fascia in certain 

 lights ; posterior wings griseous : head luteous : thorax and body 

 dusky. 



I took three specimens on the salt-marshes, near St. Osyth, Essex, 

 in July last. Two of them agree with the above description, but the 

 third has the anterior wings all griseous sprinkled with darker colour, 

 and a larger series would probably show greater variations, but the 

 species cannot be confounded with any other. 



Pcecilochroma occultana, Douglas. (Fig. 2). 



Expansion of the wings 9 lines. Anterior wings cinereous, lighter 

 towards the inner edge and near the apex, sometimes forming two 

 irregular spots, with an angular patch at the base, and an oblique fascia 

 beyond the middle, darker ; posterior wings fuscous : head, thorax, 

 and abdomen cinereous or fuscous. 



I have three specimens of this insect, two taken at Birch-wood, 

 on the 2nd of July, and one at Weybridge in June, all out of fir-trees. 

 It is also in the cabinets of Mr. Bentley and Mr. S. Stevens. 



Sericoris tenebrosana, Douglas. (Fig. 3). 

 Expansion of wings 4 lines. Anterior wings cinereous, with a
