PIERTD.E 21 



Genus 6. - RHODOCERA 



JFt. FUiamni. 



TIMES OF APPEARANCE. From the end of July to 

 October, and in the spring after hybernation. 



HABITAT. Saint-Martin-V6subie, on the Chemin 

 de Venanson (though I am not quite sure of its 

 identity), where it is rare ; it is, however, fairly 

 common at the Lac de la Madone, flying wildly 

 across the heights, at an altitude of 7503 feet. 



Not found on the coast. 



OVUM. The eggs are deposited singly on the 

 twigs of the food-plant by hybernated females, after 

 hybernation, about the middle of April. 



LARVA. On Rhamnus frangula, R. eatharticus 

 and Prunus spinosa (Blackthorn), in May, and is full- 

 fed by the end of June. 



OBSERVATION. Rhamni is essentially a native of 

 Northern and Central Europe. It is, however, 

 enumerated in all the local faunas. 



Fl. Farinosa. 



TIMES OF APPEARANCE. From the end of July to 

 October, and in the spring after hybernaton. 



HABITAT. Same as the last, of which it used to be 

 considered a form. 



LARVA. Unknown. 



Pt. Oleopatia. 



TIMES OF APPEARANCE. April and May, and again 

 in July ; but the second brood is much less abundant 

 than the spring one.
