GEOMETERS.

northern English counties ; it has also been 

 taken in Scotland, and, according to Mr. 

 Birchall, is common in Ireland. (The scien- 

 tific name is Eubolia palumbaria.) 



371. The Chalk Carpet (Euboliu bipunctata). 



371. THE CHALK CARPET. The palpi 

 are rather short, very approximate and 

 beak -like ; the antennae of the male are 

 pectinated, of the female simple ; the fore 

 wings are rather pointed, and of a chalky- 

 gray colour, with a median band, both the 

 margins of which band are darker, but its 

 median area is of the same tint as the rest 

 of the wing, and includes two small round 

 black spots placed transversely in place of 

 a discoidal spot : the hind wings are gray 

 tinged with smoky : the head, thorax, and 

 body are of the same chalky colour as the 

 fore wings. 



The CATERPILLAR is obese, pale brownish- 

 gray, with darker dorsal and sub-dorsa 1 

 stripes (Treitschke) . Stainton's Manual, 

 rol. ii. p. 49. It feeds on the Bird's-foot 

 Trefoil (Lotus corniculatus) and hybernates 

 when very small. 



The MOTH appears on the wing in July : 

 it is excessively abundant on the chalk hills 

 of Kent, Sussex, and Surrey, and it is said 

 also to be found in the north. It occurs in 

 Mr. Greene's List of the Lepidoptera of 

 Ireland, but no locality is given. (The 

 scientific name is Eubolia bipunctata.) 



372. The Oblique-striped (Eubolia lincdata). 



372. THE OBLIQUE-STRIPED. The an- 

 tennae of the male are almost simple ; the 

 fore wings are pointed ; their colour is gray, 



with three compound bars, which are uni- 

 formly oblique but direct, that is without 

 conspicuous angles : the first of these is 

 near the base, and treble, dark brown, and 

 intersected by a pale line ; the second bar 

 is quadruple, the first portion white, the 

 second dark brown, the third pale brown, 

 the fourth dark brown : between the second 

 and third bars is a distinct discoidal spot : 

 the third bar is sextuple, the shades are 

 arranged thus light brown, white, dark 

 brown, light brown, dark brown, white ; 

 there is also a short dark streak descending 

 from the extreme tip towards the middle of 

 the wing : the hind wings are gray, with 

 transverse lines both darker and lighter: 

 the body is gray. 



The CATERPILLAR is figured by Htibner 

 feeding on ladies' bedstraw (Galium veruni) ; 

 its colour is represented as wainscot-brown, 

 with a medio-dorsal and lateral line darker 

 brown ; the latter is bounded by a narrow 

 yellow line. Mr. Hellins informs me that 

 Mr. Buckler nas figured it, and that his 

 figure represents the caterpillar as " pinkish 

 on the back, with the dorsal and spiracular 

 lines dark green, the latter edged below 

 with pale green." Mr. Hellins adds, 

 "My own recollection of two caterpillars 

 I once possessed is somewhat nearer 

 Hubner's description as given in the 

 M.anual." 



The MOTH appears on the wing in May 

 and June ; it is abundant on the coast of 

 Sussex and on the Cheshire side of* the 

 Mersey ; it has also been taken in Cam- 

 bridgeshire, and, by Mr. Birchall, on Man- 

 gerton mountain near Killarney, at a con- 

 siderable elevation a strange locality, as 

 Mr. Birchall well observes, for this coast 

 insect. (The scientific name is Eubolia 

 lineolata.) 



Obs. Guenee says that this species varies 

 infinitely, and explains particular variations 

 at seme length ; nevertheless, I do not find 

 any variations that strike me as worth 

 figuring ; the beautiful varieties of the two 

 species next following have been most 

 obligingly lent me for this work by Mr. 

 Bond. I allude to the second and third 

 figures of Carsia imbutata and the second 

 figure of Anaitis plagiata.
