74 I Septernlier, 



Staudinger-Wocke's Catalogue, Herrich-Schaffer's Ch. dentoseUns, fig. 

 967, V. p. 20S is given as a synonym of my insecurelhis, an opinion I 

 am not prepared at present to endorse. 



One, however, of the recent novelties, Chauliodus iniquelhis, de- 

 scribed by Wocke in the Stettin, ent. Zeitung, 1867, p. 209, from 

 specimens found near Breslau on the flowers of Athnmanta oreoseliniim, 

 in the middle of July, seems to come so near to insecwellus that I 

 thought it possible they might prove identical, I am, however, now 

 of opinion that this is not the case. 



In August last year, Monsieur A. Constant, who is now settled at 

 Golfe Juan (not far from Cannes), sent me a box of Micro-Lepidop- 

 tera for determination, and amongst the species sent was Chauliodus 

 iniqtiellus, which he said he found in the larva state in September 

 feeding on the seeds of Peucedanum officinale and cervaria, but re- 

 maining in the pupa state all through the winter, spring, and summer, 

 the moth not appearing till the following month of August. 



In my reply I mentioned this and Ch. stricteUus as species in 

 which I was much interested, and on the 27th October, Monsieur 

 Constant having just returned from an excursion in the Esterel 

 mountains between Cannes and St. Raphael, very kindly sent me some 

 pupae- of both these species, remarking that I might expect the 

 strictellus to emerge very soon (which they did on tlie 6th and 8th 

 November), but that for the iniquellus I must have patience, as the 

 moths would scarcely appear before August, 1882. He accounted for 

 this extreme difference of habit owing to the larva of iniquellus feed- 

 ing only on the seeds of 'Peucedanum, latc-flowcring plants which do 

 not blossom till near the end of summer, whereas strictellus is not 

 restricted solely to Peucedanum but feeds also on other umbel liferse 

 (such as Ferula), which are in full vegetation at the end of October, 

 so that the perfect insects have no difficulty in finding opportunities 

 of depositing their eggs. 



These pupse of iniqtiellus I kept indoors in a cool place through- 

 out the winter and on the 7th of July, when starting for a tour in 

 Scotland I took them with me ; true to their appointed time the first 

 appeared July 19th, two more July 29th, two others August 6th, and 

 two others August 12th after my return home, I have, therefore, now 

 before me a series of iniquellus, of my own setting, which I can better 

 compare with my specimens of insecurelhis, and I come to the conclu- 

 sion that the two species are imdoubtedly distinct. 



It is notorious to any one who has devoted a little attention to 

 this genus that some of the species have the anterior wings more or
