high up in the Tuoi Valley ; .1 search for the ? was unsuccessful. 

 This species has all the aspect of being very definite and distinct from 

 the others, and affects rather swampy flats, so that its food-plants and 

 habits must be rather different from those of the allied forms, whose 

 larvae one so frequently meets with on and under dry lichen-covered 

 stones. At Ardetz, a village some few miles down the valley from 

 Guarda, an Endrosa was found abundantly in the village, sitting on 

 the usually white-washed walls of the houses, females being in about 

 the same numbers as the males. When T say an Endrom T desire to 

 leave it unsettled whether all were one species or whether there were 

 several. One ^ appeared to be almost certainly irrorella. The bulk 

 were of a radiate form I should usually call aiiriia, but these shaded off 

 iiito a fine large form of deep orange colour, and with more orange on 

 the abdomen than avrita is supposed to be entitled to. These were not 

 radiated, but with large blurred spots, and if not Kuhlweini are cer- 

 tainly a somewhat near approach to that form. Then there are two 

 neat little specimens, ^ and 5 , that resemble roscida in size, but are 

 radiate in markings. These specimens altogether increase my impres- 

 sion that irrorella, niiritn and Knliliorini are not yet fully differentiated 

 as species, and often present forms difficult to locate between 

 them. Indeed, I believe aurita and Kvlilwei7ii to be one species. 

 Irrorella can usually be easily distinguished. 



Larvfe of Plusia moneta were common near St. Morit/, and that 

 of P. ilhish'is was met with in the Yal Roseg. In the Muottas Wood at 

 Pontresina the rhododendrons were devastated by the larvae of Larentia 

 ccPRintn, and larva? of L. verherala were taken on Gamfanula rohmdi- 

 folia, and those of Oporahin dilutata were common, especially affecting 

 the honey-suckle. 



We met with the larva of an Epiclmopteryx, probably pulla or 

 one of its varieties, in gi'eat abunflance at one or two spots. One was 

 on the woodland or mountain road from Pontresina to 8t. Moritz, or 

 rather there were several spots along this road ; another was close to 

 the marshy flat in the Bernina Yalley near the entrance of the 

 Heutha], where Endrosa roscida is taken, and where also a Tortrix 

 with much the facies of vihurnana abounded. The date was about 

 the middle of July, yet a number of cases were affixed to the 

 grass stems as if for pupation. This was pi'obably, however, for 

 moulting, since not one emerged, and in the course of a week or ten 

 days all these were on the move again ; the cases were very similar to 

 those of full-grown males. Amongst the roots of the herbage and on the 

 ground at these places the cases were very abundant, so much so that
