TRUMPET-HAIES IN FULL-GROWN LARVA OF URBICOLA COMMA. 117 



been previously noted. The additional Erebias on the Pass were repre- 

 sented by Erehia melamjnis, epiphron, an abundance of Erebia tyndariis 

 and E. euryale, and one specimen of E. mnestra. The Blues by Lycaena 

 arion var. obscura (worn), Polyonimatus donzelii, P. esclmri, P. eras, P. 

 orbitulus, P. baton, and, at Iselle, P. orion. I learnt from Mr. Wheeler 

 that I was just too late for Plebeius lycidas. The Coppers constituted a 

 very attractive feature, in the shape of magnificently large and 

 brilliantly coloured specimens of Chrysophanus virgaureae, C.Ya>Y.yordius 

 and C. dorilis, all at Iselle, and one large and dark, though somewhat 

 worn specimen taken near Simplon, which I presume to be C. hippothoe 

 var. eurybia. The Skippers, amongst others, afforded Urbicola comma, 

 Adopaea lineola, and one beautifully streaked aberration of Pyrgus 

 sao on the slope between Berisal and Brigue. Here too, Epinephele 

 lycaon was taken in company with FJ. ianira and freshly-emerged 

 Issoria lathonia. The roadside yielded Satynis alcyone, S. cordula and 

 Hipparchia semele. Other species noted in the neighbourhood of Iselle 

 were Coenonympha arcania var. philea, a dark-banded aberration of 

 Melanargia galatea, Melitaea phoebe (large and varied) and Thecla 

 w-albiim, besides several Heterocera, including Anthrocera ephialtes var. 

 coronillae, Syntomis phegea, from which I obtained ova (now healthy 

 fullgrown larvae), Setina aurita var. ramosa, Cleogene lutearia, more 

 larvae of Hyles euphorbiae, the larv» of Pluna gutta on yarrow, and 

 many others, which I was unable to name or which have slipped my 

 memory. I live in great hopes of being able to explore this prolific 

 region with greater composure and less rush another season. 



Trunipet=hairs on full=grown larva of Urbicola comma {mth plate). 



By De. T. a. chapman. 



These photographs are somewhat marred by the circumstance that 

 the skin (cast at pupal moult) from which they were taken was far 

 from perfectly spread out, and the consequent wrinkles or folds are 

 conspicuous. The skin-points are present over nearly the whole field 

 in both photographs. Two spiracles are seen with their screens formed 

 by processes stretching inwards from the margins ; in both the with- 

 drawn tracheal membranes appear, and beside the spiracle in each case 

 is indicated the valve at the inner opening of the spiracle. In each 

 case the bundle of tracheal tubes from the preceding spiracles is more 

 conspicuous below the spiracle shown than that proceeding from the 

 spiracle itself. The lenticle shown presents the usual resemblance to 

 a spiracle, it also shows a feature common in those of this larva, viz., 

 a finger-like process extending from the margin into the lumen of the 

 lenticle. In some cases there are several such processes reaching 

 towards the centre, one might suppose in an attempt to resemble the 

 screen processes of the spiracle proper. The opening of the lenticle is 

 filled in by a membrane dotted with fine points. Near the lenticle is 

 a hair that is nearly of ordinary form, this may, perhaps, be tubercle 

 iii, but such hairs are so rare on the larva that they cannot be assigned 

 to tubercles, except very hypothetically. The trumpet-hairs, varying 

 in the figures from O-OSmm. to 0-06mm. in length (slightly longer in 

 some other situations), have very obvious conical bases. They expand 

 slightly upward, and terminate by a slight contraction (usually) at the 

 spiculated mouth.
