CONTRIBUTIONS TO HISTORY OF THE BRITISH PTEROPHORI. 35 



Mimceseoptilus zopliodactylus, Dup. 

 loewii, Zell. 



Imago. — Expanse, U-10 lines. Fore wing pale grey-brown, slightly 

 tinged with violet and dotted with black scales, a black dot on disc of wino, 

 and another at the lower edge of digital juncture; at the base of the grey- 

 brown fringes are four small black dots, two of which are placed at angle of 

 outer digit, and two near tip of inner digit ; costa towards apex whitish, 

 sometimes the entire costa is edged with whitish. Hind wing dark grey- 

 brown. August. 



Larva. — Length, 5 lines, tapering towards anal extremity. Head 

 shining yellowish green, smaller than 2nd segment. Ground colour 

 yellowish green, with a broadish violet dorsal stripe from the 3rd to the 13th 

 segments mclusive; there are numerous short pale grey hairs arranged in 

 four lines along the dorsal and lateral areas, but no well-defined tubercles. 

 Spiracles dark brown. September, in the flowers of EnjthrcBa centaureum. 



The foregoing description of the larva of M. zopliodactylus 

 has been already published in Mr. Leech's ' British Pyralides.' 

 Lafaury records larva of M. zopliodactylus on Chlora perfoliata, 

 and suggests that probably it is a miner when j'oung (Pet. Nouv. 

 vii. 533). This species is separable from M. bipunctidactylus by 

 its whitish apical edging. 



Pterophorus hodgkinsonii, Gregson (E. M. M. iv. 178). 



This insect is characterised by Mr. Gregson, as follows : — 



" Alar expanse, 7-8 hnes. Head, face, thorax, body, and legs light, 

 creamy, ashy-grey, lightest towards the cleft, very slightly irrorated with 

 darker atoms ; the discoidal and cleft-spots scarcely perceptible. Under 

 wings rather darker than the upper wings." 



Although not so stated, I apprehend that the " ashy grey, 

 lightest towards the cleft," &c., refers to the primaries ; if this is 

 so, I have some specimens of M. bipunctidactylus from N. Devon, 

 which agree very well with the description of hodgkinsoni. The 

 time of year fits my insect also, and it differs from the type in 

 precisely the same manner that hodgkinsoni is said to differ from 

 M. bipunctidactylus. As I have not yet seen a specimen of 

 hodgkinsoni, I cannot of course say that it is a form of bijmncti- 

 dactylus, but I think it may turn out to be a form of that species, 

 rather than a var. oi zopliodactylus, Dup. 



Leioptilus osteodactylus, Zell. 



Imago. — Expanse, 9^-101^ lines. Fore wing sulphur-yellow, streaked 

 with brownish from the base to the middle of the wing, a broad ill-defined 

 brownish patch on the costa before the apex, and a black spot at digital 

 juncture; fringes pale brown. Hind wing pale, shining brown. July and 

 August. 



Laiiva.— Ground colour whity-brown, with a greenish tinge, and 

 thickly sprinkled with minute black dots; dorsal stripe and subdorsal line
