CONTINENTAL INSECTS OF VARIOUS ORDEES 

 TAKEN BY DR. T. A. CHAPMAN IN 1913. 



By W. J. Lucas, B.A., F.E.S. 



Pupa-skin of Ascalaphns coccajus. Magnification a little over 2^ nat. size. 



One antenna could not be withdrawn, and it is shown broken, or bitten off. 

 The pupal-jaws are well seen ; and it must be borne in mind that they were 

 worked by the imaginal jaws that were not then withdrawn from them. The 

 pupal-skin is very ethereal, as can easily be seen. The head has become detached 

 from the body. 



After each of two entomological excursions to the Continent 

 in 1913, Dr. Chapman was kind enough to give me a small 

 collection of insects, which he was able to take, belonging to the 

 less-known Natural Orders. In April, May, and June, he visited 

 the Rhone valley in Switzerland and the district of the Italian 

 Lakes, and this first collection contained insects from Sierre 

 (1760 ft.) in the Rhone valley, from Locarno (680 ft.) on Lago 

 Maggiore in Switzerland, and from Pallanza (680 ft.), also on 

 Lago Maggiore, but in Italy. 



In July and August the scene of operations was transferred 

 to France, and the second collection contained insects from 

 Lautaret (6790 ft.) and Bourg d'Oisans (2360 ft.) in Dauphine. 

 The former is a well-known botanical and entomological locality, 

 and the latter is in the valley of the Rimauche, on the way up to 

 Lautaret. 



My thanks are due to Mr. K. J. Morton for naming a number 

 of the specimens.
