136 BKITISH BUTTERFLIES. 



median interspace ; a bifid spot at the end of the cell ; a series of five 

 quadrate spots, excised in front, crossing the disc obliquely from sub- 

 median to upper radial vein, and a trifid spot across the subcostal 

 branches, half-way between the cell and the apex, buff; secondaries 

 with angular discal series of five ochreous spots. Wings, below with 

 the markings paler than above, the spots creamy-whitish or pale bone- 

 yellow ; disk of primaries round the borders of the oblique series of 

 spots olive-brown ; external angle and outer border whity-brown ; 

 secondaries bronzy olive-brown, the discal series consisting of six spots, 

 anal angle broadly ochreous, outer border tinted with ochreous ; palpi 

 white ; body below bluish-grey. Expanse of wings 1 inch 1\ lines." 



e. var. tochrana [Brem.] , Riihl, " Pal. Gross-Schmett.," p. 643 (1895); Tutt, 

 " Brit. Butts.," p. 126(1896). — Imago 32mm.-35mrn. This is also a large form, 

 which actually forms a transition to subhyalina, but nevertheless comes nearer to 

 sylvanus than to the other species. Upperside almost as bright brownish-red as in 

 the typical form, but the outer margins are generally more strongly darkened. The 

 arrangement of the spots as in sylvanus, and not so pale and vitreous as in 

 subhyalina. Underside of a very deep reddish-yellow, almost cinnamon-brown, 

 with sharply denned dark nervures. Locality — Hakodate, June- July (Riihl). 



£". var. (an spec, dist.) faunus, Turati, "II Nat. Sic," xviii., pp. 36-37 ; pi. 

 vi., tigs. 5, 9 ; vii., fig. 3 (1905). — Fulvo-ochracea ; fascia externa brunnea dis- 

 tincta, ad apicem angustiore quam in sylvano. Antennis tenuioribus unicoloribus 

 fuscis ; clava subtus fulva (Turati). 



This is described as a distinct species, but we are not able to dis- 

 tinguish between the figures of this form and our ab. extensa. One $ only 

 was captured, at Gavarnie, July, 1894 ; it is 28mm. in expanse ; ground 

 colour rather deeper than that of sylvanus, less brown than comma ; 

 dark brown outer marginal band rather narrower than in sylvanus, <kc. 

 The hindwings with an almost uniformly wide marginal band ; other- 

 wise as in sylvanus. On the underside of the forewings the pattern is 

 more distinct than is usual in sylvanus ; the hindwings have the inter- 

 neural spaces marked with elongate pale yellowish spots, instead of the 

 ordinary pattern of sylvanus (Turati). 



Egglaying. — On August 8th, 1905, at Bourg St. Maurice, on a 

 flowery bank, where Adopaea thaumas, A. lineola, Thymelicus acteon, 

 Urbicola comma and Augiades sylvanus were all occurring together, 

 I observed a $ sylvanus in the act of egglaying. Standing length- 

 wise on the front of a grass-leaf, she very carefully turned her 

 abdomen around the left edge of the leaf, and felt for a moment 

 before withdrawing it; she then hurriedly darted off, returning, 

 however, almost immediately to the same leaf, settling near the top, 

 and sliding quickly down to the same point as before, and going through 

 a similar series of movements as on the first occasion, again flying away 

 quickly not to return. I fully expected to find two eggs on the back 

 of the leaf, but there was only one, which, I think, she must have laid 

 on the first occasion ; it was just round the left edge of the leaf (from 

 the point of view of the insect facing the front surface) and laid as an 

 ordinary upright egg (Tutt). In July, 1868, a $? was observed flying 

 from one stem of grass to another several times, as if particular in 

 selecting, and, having found a suitable one, slid gently, but quickly, 

 down it, apparently by means of the legs; when she was gone 

 the sheath formed by the leaf round the upper part of the stem was 

 examined, and about thirty small white eggs deposited in a line found 

 therein (Ullyett). A ? was observed to lav three eggs side by side on 

 t he undersurface of a grass blade, July 17th, 1897, and others on June
