c hir.d wings are pale grayish brown : 

 tin 1 head, thorax, and body are darker and 



Iky. 



The head of the CATERPILLAR is pale green 



d unicolorous ; the dorsal area is a deep 

 green colour, with certain stripes distinctly 

 marked ; the mcdio-dorsal stripe is dark be- 

 tween two linen of bright green ; on each side 

 of this is a whitish stripe shaded below with 

 dark green ; below this, in the region of the 

 spiracles, is a white stripe ; the spiracles above 

 arc reddish and surrounded with pale yellow- 

 ish green : the ventral area is green with three 

 white stripes. It feeds on the common broom 

 (fyitrfitnit scojwn'um}. I have freely trans- 

 lated this from Guenee's description ( Uran. ct 

 Pint!., vol. ii. p. 506) 



The MOTH appears on the wing in Sep- 

 tember ; it has been taken in the north, south, 

 east, and west of England, and near Glasgow, 

 and Mr. Birchall informs us there is a speci- 



en in the late Mr. Tardy's Irish collection, 



utils habitat is unknown. (The scientific 

 name is Chcsiits spartiata.) 



317. The Broom Tip (Chesias obliquaria). 



377. THE BKOOM TIP. The antennie are 



simple in both sexes ; the palpi rather long and 

 porrec.ted, in the form of a beak ; the fore wings 

 are long, obtusely pointed, and narrow, with 

 two indistinct angled lines before the middle, 

 and a dark abbreviated band beyond the middle; 

 this band originates on the costal margin, and 

 is conspicuous half-way across the wing, 

 whence it is continued as a very indistinct 

 double line to the inner margin ; between the 

 abbreviated band and the tip is a smoky costal 

 blotch ; there is a broad hind-marginal band 

 of a smoky-gray colour intersected by a sub- 

 marginal pale scalloped line : the head, tho- 

 rax, and body are of the same colour as the 

 fore wings. 



Mr. Machin beat seven or eigh't of the CATER- 

 PILLARS off common broom (Sparthim scopa- 

 rhini) in 1856, and bred the perfect insect in 

 1857 : it closely resembles the caterpillar of 

 C. Spartiata, but is of a rather darker green, 

 and wants the yellowish tinge ; Mr. Machin 

 also thought it thicker towards the head, and 

 not quite so smooth. It feeds exclusively on 

 the common broom (Spartium scoparium}. 



The MOTH continues on the wing from the 

 middle of May to the middle of July ; Mr. 

 Machin took it without intermission from the 

 20th of May to the 7th of July. It occurs in 

 Surrey, Kent, and Suffolk, and has also been 

 taken in Scotland. (The scientific name is 

 Chesias olliquaria.} 



Obs. This insect is called "the Chevron " 

 by Donovan, a name which belongs properly 

 to Cidaria testata ; and "the Broom Buff- 

 tip " by Harris and Stephens : I have adopted 

 Haworth's English name in order to avoid 

 confusion. 



373. The Chimney Sweeper (Tanayracliairoplyllala}. 



378. THE CHIMNEY SWEEPER. The fore 

 wings are rather ample and rounded at the 

 tip; their colour is sooty -black, the fringe 

 snowy-white at the tip and interspersed with 

 white on the hind margin : the hind wings, 

 head, thorax, and body are sooty -black. 



Mr. Buckler has thus described the CATER- 

 PILLAR from specimens found by Mr. Howard 

 Yaughan, to whom we are indebted for the 

 discovery of its food-plant: " When full grown, 

 is nearly three-quarters of an inch in length, 

 cylindrical, short in proportion, and almost 

 equally thick throughout, rather shining, and 

 with distinct lines, as follows : Ground co- 

 lour of the back green or bluish green, be- 

 coming on the sides gradually paler towards 

 the spiracular regions. The dorsal line is 

 darker green, and on the anal segment be- 

 comes dark red and thicker, forming a very
