CHRYSOPHANUS DISPAR VAR. RUTILUS, WERNB., IN HUNGARY. 13 



3. Nemobius lineolatus, Brulle. 



Resembles the preceding, but larger ; elytra of 3 with hind border 

 truncate, with differences in the venation ; hind tibiae with different 

 armature (see table of species); ovipositor crenulate at the apex. 

 Length of body, 9mm. $ and 3 ; of pronotum, 2mm. 3 and $ ; of 

 elytra 5mm. 3 , 4-8mm. 5 ; of ovipositor, 5.2mm. 5 . 



In similar localities to the last, but rarer. In France rare and 

 local, only known in the south ; on the banks of the Adour near 

 Saint Sevez, Mont de Marsan in the Pyrenees, on the banks of the 

 Drac near Grenoble, Bagneres de Luchon, in Loire Inferieure, I'Asse 

 near Digne, Bagnols, Saint Paul in Var. In Italy at Pegli, but 

 rare and local. 



Azam describes a variety fabri/i, in which the wings are hyaline 

 with brownish veins, the elytra twice as long, reaching the end of the 

 posterior tibiae ; this variety is based on a female taken at Cellier in 

 the Loire.

Chrysophanus dispar var. rutilus, Wernb., in Hungary. 



By The Hon. N. CHA.RLES ROTHSCHILD, M.A., F.L.S. 



In. the late summer of 1907, 1 was fortunate enough to see Chrysop- 

 hanus dispar var. rutilus in its native haunts in Hungar3^ The insect 

 is fairly common near the villages of Csehtelek and Kozepes in Bihar 

 Comitat. This beautiful butterfly occurs apparently everywhere in the 

 district where the ground is liable to floods. All along the valley of 

 the small river Bisztra are wet meadows, under water in the spring 

 and nearly dry in the late summer and autumn. They are the great 

 sources of haj' in the district, and are mown twice a year and grazed 

 as well. A few docks, not the large Itumex lujdrolapathum, among the 

 grass, some small plants of Iris pseudacorus, and an occasional shallow 

 depression filled with a small reed-like grass, are the characteristic 

 features of these fields. C. rutilus flies about rapidly in these meadows, 

 which are very similar to those in the valley of the Nene, between 

 Northampton and Peterborough. The docks, which are all riddled 

 with holes (doubtless due to the larva? of the butterfly), are so few in 

 number that the insect must have other foodplants, possibl}' Polygonum 

 bistorta, which Aigner''= states it eats in Hungary. I also found the 

 insect in an open space in a forest at Csehtelek where a small brook 

 occasionally overflows its banks. At Kozepes, a village in the Rez 

 mountains, a tiny stream trickles out of the forest which clothes the 

 mountains, and, in a small space, under an acre in extent, overgrown 

 with Eupatorium, I took some dozen examples of the butterfly. There 

 is a considerable variation in size of the specimens I secured, although 

 they were all taken between August 20th and September 7th. Aigner 

 [I.e.) says that specimens of the second-brood are larger than those of 

 the first, but this does not seem to be constant. The smallest male I 

 secured measures 25mm., and the largest 33mm. Females are 

 naturally larger, my specimens ranging from 28mm. to 37mm.
