THE PINION-STREAKED SNOUT. 95 



probably more often neglected than secured when met with. 

 The moth under consideration, and of which the sexes are 

 figured on Plate 36 (Figs. 3 $ and 4 ? ) has brownish fore 

 wings which are crossed by two rather irregular blackish lines, 

 sometimes hardly traceable on the front margin ; the outer line 

 is edged externally with whitish, and the space between the 

 lines is often somewhat darker ; the black central mark is more 

 or less X-shaped. 



The caterpillar does not seem to have been noted in this 

 country, and it is not well known on the continent. It is said 

 to feed on the flowers, chiefly the withering ones, of heather 

 and thyme, in August and September. 



The moth is out in July and early August, sometimes in 

 September. Its haunts are the edges of woods, hillsides, and 

 sloping banks, where there is plenty of bushes and herbage to 

 hide in. From such retreats it may be disturbed, but is more 

 easily obtained at sugar, or honey dew, and sometimes at ivy 

 bloom. It is widely distributed over the southern half of 

 England ; occurs in South Wales, and has been recorded from 

 Cheshire and Yorks. 



Abroad, the species is found in Holland, Belgium, Germany, 

 Austria, Armenia, and the Canaries ; also recorded from south 

 Sweden and Corea. 



The Pinion-streaked Snout {Hypeiwdes costcestrigalis). 



Although somewhat similar in the general colour of the fore- 

 wings, this species (Plate 36) may be distinguished from the 

 preceding by the whitish dash from the tips of the wings and 

 the black streak running inwards from it ; this black streak is 

 to be seen clearly in Fig. 6 5 , but owing to the darker ground 

 colour is less distinct in Fig. 7 9 . 



The caterpillar is shining purplish-brown, inclining to 

 yellowish-brown below, with three pale brownish lines along
