8 THE ENTOMOLOGIST. 
Hesperia tessellum. 
Caterpillars were found from the middle of May to the 10th 
of June on a species of Phlomis (certainly from the description, 
P. tuberosa). The larve spin the two edges of a leaf together on 
the upper surface, and live within this leaf. The colour of the 
larva is mouse-grey, with a black head and yellow collar. There 
are two black rows of dots on the back, an excellent characteristic 
of the species. The imago begins to emerge after the middle 
of June, and there is apparently a partial second brood in the 
beginning of August. 
Hesperia cribrellum. 
The larva of this species is indistinguishable from that of 
H. carthami var. meschlert, and lives spun up among the leaves 
of a species of Potentilla. The caterpillar is full-fed in May, and 
the imago emerges at the beginning of June. 
A BUTTERFLY HUNT IN SOME PARTS OF 
UNEXPLORED FRANCE.

(iv) Isére and Dréme. The Vercors. 
AFTER a year’s silence on the subject of ‘‘ fresh woods and 
pastures new”’ explored in France, I am again able to take up 
my pen to continue the series of short papers published by me in 
the ‘Entomologist’ for 1911-12. And I am the more encouraged 
to do so when I hear that my brother naturalists and collectors 
not only read these papers, but actually follow in my footsteps; - 
and this at other seasons of the year than those of my travel. 
So that, as time goes on, we may hope to obtain not only a 
fleeting record of the captures and observations of a week or two 
spent in the several localities, but a solid contribution to the 
knowledge of the lepidoptera occurring there from year’s end to 
year’s end. Most of us are compelled to do our collecting at fixed 
times of the year—usually in July and August—in the holiday 
season in fact. It has seldom fallen to my lot to get abroad 
before the last week of June, when the first flight of most of the 
southern species of the plains is over. And this year I did not 
leave London before July 1st. 
For some time past I had had my entomological eye, so to 
speak, fixed on the western Dauphiny, that is to say, the country 
west and south of Grenoble, between the Isére and the Drome, 
and within the departments bearing the names of the respective 
rivers. An application to the Cyclists’ Touring Club of France for 
information of this region brought me among other fascinating
