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 larvae 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. moeschleri, 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 OP 

 UNEXPLORED FRANCE.

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 naturahsts 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 Ist. 



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 Isere 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
