Captures of Micro-Lepidoptera in Essex. — During the past season I have had 

 the good fortune to capture, in addition to Opostega spatulella, elsewhere referred 

 to, the following Tineina : two Scythropia cratcegella on June 27th : I also bred 

 several of this insect from larvae taken on white-thorn ; one JSucculatrix cristatella 

 on June 4th ; two Cleodora cytisella on July 12th ; one Bedellia somnulentella and 

 one Gelechia lutulentella on August 23rd ; and three Depressaria ultimella on 

 September 10th. I may also add that I succeeded last spring in breeding a few 

 specimens of Nepticula intimella from mines (Sallow) taken in October, 1876. —

ISrotesis haltica, McLach. ; a Trichopterous insect new to Britain. — In part vi 

 (May, 1877) of my Revision and Synopsis of European Trichoptera, I described (pp. 

 325, 326, pi. xxxv) a new genus and species of LeptoceridcB under the above name, 

 from specimens taken in the Island of OEsel in the Baltic, and in Finland ; all males. 

 My friend Mr. Barrett has just sent me four males, taken by Mr. F. D. Wheeler, in 

 Wicken Fen, I know not under what circumstances, but probably they were attracted 

 by the mgenious "light" apparatus, noticed in this Magazine, vol. xiii, p. 246. It 

 occurred to me at the time that Mr. Wheeler's apparatus might prove of great aid 

 in the capture of fen Tricho2)tera. 



E. haltica somewhat resembles Tricenodes bicolor, but the colours are less bright. 

 In structure, Erotesis agrees with Tricenodes in the absence of the apical fork No. 5 

 in the neuration of the posterior wings ; but it differs in having a complete " cellula 

 thyridii" in the anterior wings (wanting in Tricenodes). The complicated arrange- 

 ment of the anal parts in the (J is fully detailed and figured in my work ; the ? is 

 still unknown. — R. McLachlan, Lewisham : 13th November, 1877. 



A new species of Ant found in Britain. 



PONERA TAEDA, Sp. n. 



Female, length, 2 lines. Shining, rufo-piceous, sparingly covered with a fine 

 yellowish pile. Head punctured, wider than thorax ; antennae and mandibles yellow, 

 approximating at their base ; eyes ovate, placed anteriorly at the sides of the head ; 

 ocelli in a triangle on the vertex, a longitudinal impressed line runs from the an- 

 terior ocellus to the insertion of the antennaj. Thorax oblong-ovate, slightly 

 punctured ; clypeus and femora rufo-testaceoiis, tibiae and tarsi yellow. Abdomen 

 slightly punctured, the scale of the petiole as high as the first segment ; a constriction 

 between the first and second segments ; the apex dull yellow. On the fore part of 

 the head, and on the posterior part of the abdomen a few strong hairs are emitted. 



Worker major, length, 2\ lines. Shining, ferruginous. Head very large in pro- 

 portion to thorax, without ocelli ; on the anterior part of the head in the position of 

 the eyes in the female, is a minute spot surrounded by a dark ring, and looking very 

 like an ocellus. The antenna? and legs the same colour as the body, the former 

 rather darker at the apex. The head more lightly punctured than in the female, or 

 in the small w^oi'ker. 



Worker minor, length, 1^ lines. Resembles female generally, but differs in being 

 of a lighter rufo-fuscous colour. Without eyes or ocelli. A longitudinal impressed 

 line running from the base of the head to the insertion of the antennae. 



Mfllo unknown. ^
