Larva. Length 1"-1"2"'. Body not hairy, but stadded everywhere, except 

 on the head, with extremely fine, yellow, little warty dots (Punktwarzchen) . 

 Ground colour yellowish-green, the rounded head pale green. Mouth yellowish, 

 on the inner margin of the mandibles brown. Dorsal line narrow, dark green, 

 bordered on each side with a sharp, narrow, whitish-yellow line. The upper lateral 

 line is slender, rather yellower, edged above with dusky ; the lateral lino in which 

 the spiracles are placed is broader, pale yellow, very distinctly defined. Legs 

 very short, only the anal prolegs pale rose-coloured. Anal points not long, 

 pointed, clear green, rose-coloured at the extremity, or entirely of the latter colour. 



The freely-suspended pupa has quite the form and colour of C. Pamphilus. It 

 is 6"' long, completely naked, pale green, on the thoracic shield more transparent than 

 on the wing-cases, on the abdomen more whitish, and quite opaque; the inner margin 

 (margo dorsalis) of the fore-wings is bounded by a fine whitish line, and outside by a 

 still finer brown line ; the abdomen, on the first six segments is very finely wrinkled 

 smooth on the hindermost. The empty pupa-case is whitish, on the last segments 

 dirty light greenish ; the boundary line of the wing-cases distinct. 



With respect to the perfect insects in. this neighbourhood. I have only to say 

 that they never seem to occur with an entire white band on the underside of the 

 hind wings ; that the ground colour is here often strongly mixed with ochre 

 yellow ; that the pale transverse line on the underside of the fore-wings is often 

 quite obsolete, and that a $ in my collection lias here four ocelli : above the usual 

 one a small one, under this a small round yellow spot without black ; next, near 

 the anal angle, a larger ocellus with a white pupil, and at the anal angle a smaller 

 one without a black pupil. Such specimens as I received from Livonia, and des- 

 cribed in Isis, 1846, p. 180, as Hipp. Isis, Zetterst., though only as a variety of 

 Davus, do not appear to exist in our district. That these are not the typical 

 form there, two of the ordinary Livonian Davus of my collection show. I have 

 not yet seen the species in our neighboux'hood so small as three genuine Lapland 

 specimens of Isis $ (Davus, var.) in my collection, which are smaller than many 

 South European Pamphilus (var. Lyllus, Esper. ?)." 



The above description appears to me to belong to C Typlion, Haw. I hope, now 

 that the larva of one of this puzzling group of Coenonympha has been well recorded, 

 our collectors will be able to detect those of the various forms in this country, and 

 inform us whether we have two or more species in our cabinets, mixed up under 

 the name of 0. Davus, or not. I may add, that the description of C. Davus given 

 by Fabricius in his " Genera Insectorum," p. 259, is certainly applicable to the 

 Davus of Haworth, and not to Typhon. The description in his " Mantissa Insec- 

 torum," ii., 33, n. 347, appears to belong to C. Davus. On the same page, n. 352, 

 we find Esper's Typhon erroneously described under the name of Hero ; but 

 Staudinger cites both these synonyms as belonging to C. Iphis, W. V. —

Description of the larva of Ccnnonympha Davus. — On the 22nd of August, 1864, 

 Mr. Newman kindly sent me two young larvs8 of this species, which had been bred 

 from eggs, obtained (and described as far as their second moult in the " Zoologist," 

 No. 275,) by Mr. Sanmcl Hudson, of Epworth, and to whom I have been very
