Dr. Bomei immediately began his researches on the summits of 

 the mountain mass of the Sibillini, specially looking for P. apolln, E. 

 ligea and E. tyndarus, but he found absolutely nothing. Pursuing his 

 researches in the less elevated localities he collected from August 2nd 

 to 13th a few specimens of H. foulqaieri, A. comma, H . virgaureae, A. 

 thetis, P. icarus, P. In/las, Z . transalpine, and a great number of A. 

 coridon and E. neoridas. All the other species of the second period 

 were absent notwithstanding that the epoch was just that of their 

 emergence. 



My son-in-law had collected with us on the Monte Sumbra many 

 A. coridon in July, and now he found the same species which emerged 

 later on account of the greater elevation of the mountain mass. The 

 conditions of capture were also changed : on the Sumbra the A. 

 coridon could take refuge in the evening on the stems of grass and 

 their capture was much easier ; on the Sibillini instead all the grass 

 had been destroyed by the prolonged drought. An infinite number of 

 A. coridon flew near the ground without finding convenient resting 

 places. In order to capture them with greater ease Dr. Romei 

 diverted a stream of water and inundated a zone of ground, the thirsty 

 A. coridon hurried to it and could be captured in masses by beating 

 the ground with the foot, making them fly and taking them on the 

 wing. In this way he was able to bring back about two thousand 

 very perfect specimens, amongst which were some notable specimens 

 of the form cinnus, Hb., and corydonis, Bgstr. 



Towards August 20th all emergence Of insects ceased, and on 

 September 1st my son-in-law returned to Florence and we went 

 together to see if by the effect of the rains the " pause" had finished 

 at the Pian di Mugnone. The ground had greened over, many 

 flowers had come out, and the absence of Lepidoptera was not so 

 marked as in the preceding months of June, July and August. 



From September 5th to 20th there was a great emergence of the 

 species which in normal years appear in August. At first Dr. Romei 

 and I, and afterwards also my wife and daughter, who had esca.ped 

 from the earthquake of the Garfagnana, collected assiduously, and I 

 give here the list and the comparison with the preceding years: — 



A r . tages, L., race clarus, Carad. II. gen. clarus. — Only one pair: 

 male and female. 



/'.'. altheae, Hb., race australiformis, Vrty., II. gen. australiformix. — 

 Absent. 



E. alceae, Esp., race australix, Z., II. gen. australis. — Only 

 one male. 



//. on'opordi, Ramb., race fulrotincta, Vrty., II. gen. fidrotiucta. — 

 Several individuals, but the underside is not so fulvous as in the 

 specimens of the Camaione valley. 



hi. armorictinus, Obthr., race fulvoimperm, Vrty., II. gen. fulvo- 

 inspersa. — Same as before.
