206 THE ENTOMOLOGIST. 



centage died, and the few moths that came forth in 1889 were 

 miserable little creatures ; however, as a diminutive Irish male 

 (32 mm.), one of the whitest that I had seen, and a small 

 English female (36 mm.), happened to emerge on the same day, 

 they were put together ; on the following morning they were 

 paired, and ova were deposited same evening. The majority of 

 these ova showed by ultimately turning colour that the larvae in 

 them svere alive, but only four came forth, three fed up well and 

 pupated, the other lingered on for an unduly long time and died ; 

 but the only imagines that resulted were two full-sized males, 

 measuring respectively 38 mm, and 37 mm. in expanse. 

 Throughout the series of broods, due care was taken to keep the 

 larvffi supplied with a sufficiency of fresh food and to prevent 

 overcrowding. 



The colour of the English males was uniformly the typical 

 sooty brown ; that of the Irish males varied from creamy white 

 to pale ochreous brown, the females of both forms being alike, 

 i. e., the typical smoky white. The crossbred examples most 

 nearly resembled the darkest of the Irish form, being of the 

 same pale ochreous brown colour but with a smoky tone and the 

 fringes faintly paler.

CONTRIBUTIONS TO THE GEOGRAPHICAL AND VERTI- 

 CAL DISTRIBUTION OF THE RHOPALOCERA IN THE 

 HAUTES-PYRENEES. 



By W. Harcourt-Bath. 



The following paper is the result of a preliminary visit which 

 I paid to the Central Pyrenees, situated in the French Depart- 

 ment of the Hautes-Pyrenees, during the latter half of July 

 and the beginning of August last year. I have already given 

 an account of the vertical zones, together with a brief sketch 

 of the vegetation, in a previous article in the 'Entomologist' 

 (November, 1896). 



Although the scenery in the region under consideration is 

 generally far grander than in that portion of the chain included 

 in the Department of the Pyrenees-Orieutales, the PJiopalocera 

 fauna of the former is not so rich. Unfortunately I was not 

 favoured with very good weather ; half the time I was there it 

 was either wet or dull, while during the same period the whole 

 of Europe to the north was enjoying a drought of almost unpre- 

 cedented severity ; but it is generally the case that when anti- 

 c3^clonic conditions prevail in Central Europe, the weather 

 further south is as a consequence bad. It was in fact one of 

 most rainy seasons that they have had in the Pyrenees for a
