234 Mr. R. M'Lachlan's Descriptions of the 



sliire : Newman, from Leominster ? : Parfitt, from Exeter. I 

 have also specimens from Scarborough, and have seen others from 

 the Isle of Wight. 



Curtis's types of aS". Vibex consist of four specimens, viz., one 

 male answering to tlie above description and two females, which 

 probably also belong here, and one male of S. striatus. The 

 description in the *' Philosophical Transactions" is very short, and 

 will apply equally well to several species. This species is not in 

 Stephens's collection ; his Vibex and hieroglyphicus are one 

 species, which is not contained in Curtis's collection. 



5. hieroglyphicus, Stephens. (PI. IX. fig. 2.) 



Halesus hieroglyphicus, St. 111. Mand. 6, p. 210, 5; H. Vibex, 

 St. 111. 209, 3 ; Anatolia hieroglyphica, Brauer, N. A. 48, 5, 

 figs. 58, 59 ; Stenophylax striatus, Kol. Gen. et Sp. Trichop. 

 pi. 1, p. 64, 4; Limnephila striata, Ramb. Nevrop. p. 479, 

 11 ; Stenophylax Vibex, Hagen, Ent. Ann. 1859, p. 92, 31. 



Similar in size and form to the preceding. Antennae reddish- 

 ochreous ; head and thorax reddish-ochreous, the latter darker 

 on the sides ; abdomen fuscous above, reddish-ochreous beneath ; 

 legs reddish-ochreous ; anterior wings pale reddish-grey, thickly 

 sprinkled with small pale yellow spots ; the anterior (area costalis) 

 and posterior margins are pale yellow, a large pale yellow spot 

 enclosing the thyridium is connected with a more or less distinct 

 semilunar blotch at the base of the apical cells ; veins, especially 

 those of the cubitus, dark ; posterior wings sub-hyaline, slightly 

 yellowish at the apex. 



Upper margin of last abdominal segment cut off nearly straight, 

 with a slight depression in the centre ; appendices superiores con- 

 cave internally, triangular at the base, deeply notched on the 

 anterior margin, with the apex curved inwards and very acute, the 

 margin darker coloured ; appendices inferiores broad, oblique, 

 cut off anteriorly with a tuft of long hair on the margin ; lower 

 sheaths with the tips approximating. 



Long. Corp. 7 — 8 lin. ; exp. alar. 17 — 21 lin. 



In this country the commonest species of the genus, and very 

 widely distributed, appears in May, and continues out for some 

 months. 



This may be distinguished at first sight from the preceding 

 species by the pale costal margin being narrower, and the form of 

 the superior appendages is very different from any other. As said 

 before, no original specimens of this species exist in Mr. Curtis's 

 collection, so that this cannot be his L, Vibex. The appendages
