38 THE ENTOMOLOGIST. 



To see a N. chaonia emerge from its cocoon on an evening 

 towards the end of April is very striking. The majesty with 

 which it marches to the top of the cage, and poses, to allow its 

 wings to grow, is quite singular. The male is apt soon to grow 

 so restless, especially if the evening is warm, that it will often 

 destroy itself the first night. The female is more sedate, hut 

 less so than dodonea. 



I once found two ova laid on oak bark in a shady spot. They 

 are white and conspicuous, and have been found on fronds of 

 fern, owing to some accident. 



To obtain this insect in any numbers, recourse must be had to 

 the beating-tray, and it seems to occur more freely in the New 

 Forest than anywhere else. Marlow Common is also a good 

 hunting-ground for it; as are Burnham Beeches and Stonor 

 Park, in the same neighbourhood. Although the larva when 

 young is easily confounded with that of dodonea, yet the large 

 green head of the former is a sufficient mark to distinguish 

 it ; and when full grown it is much stouter and more glossy, and 

 altogether different.

AN ENTOMOLOGICAL WINTER CAMPAIGN IN SPAIN 



AND NORTH AFRICA. 



By G. Dieck. 



On the 5th January I arrived in Gibraltar, and hastened 

 to take a walk on the rock, from whence 1 hoped to see 

 Tangier and Algeciras, the places I intended to visit next. On 

 my way I took the opportunity of fishing out of the reservoir 

 some floating beetles : among them the scarce Asida inqiiinata, 

 Carabus hceticiis, Pristonychus hcsticus, Geotrupes marginatus, 

 Cyrtonus, Eumolpiis, were si^ecially to be noticed ; except for these 

 and Ocypus olens, Orthomus harharus, and a variety of Licinus 

 silphoides, a few Halticidse, by sweeping, Attains uUcis, and Bar- 

 idius opiparis, one example, there was little sign of activity in 

 the fauna. 



When I arrived at the summit of the rock a far greater joy 

 awaited me. Wherever the eye turned, on all sides the most
