ZYGAENAE OF PENINSULAR ITALY. 25 
Comparative data and statistics on some Zygaenae of Peninsular 
. Italy. 
By ORAZIO QUERCI. 
I, ZyGaENa TRANSALPINA, Hsp. 
The Italian Zygaenae have been made the subject of accurate 
studies by many entomologists, who have described species, races, and 
many individal forms. Being in possession of abundant materials I 
propose to furnish, above all, exact statistics, and to make observa- 
tions in order to establish, on real numerical bases, the frequency of 
the particular forms in the races of Central Italy, leaving to Dr. 
Verity the synthetic comparative study of the same races, and their 
nomenclature. . 
The specimens which I possess come chiefly from the following 
localities, in which my family have collected during the last ten 
years :— 
1. Florence, Tuscany, Central Italy.—Gvassy clearings in the oak 
coppices of the Pian di Mugnone (600 ft.) and of the Fiesole hills 
(1,700 ft.). 
2. Fonte-buona, Florence.—Meadows on the slopes of Poggio 
Conea (1,200 ft.), near Monte Morello. 
3. Palazzuolo di Romagna, Tuscany.—Meadows at about 1,000 ft., 
amongst the oak woods on the slopes of Monte Carsolano. 
4, Montefegatesi, Lucca, Tuscany, 
ground on the slopes of Monte Pratofiorito (3,000 ft.). 
5. Firenzuola, Florence.—Clearings at about 1,500 ft. above the 
sea, in the locality called il Palasaccio. 
6. Macerata, Marche, Central Italy.—Clearings in the oak woods of 
Colle Torri (900 ft. above the sea). 
7. Bolognola, Macerata.—Bare slopes and clearings among the 
beech woods on the Sibillini mountains (3,600 ft.). 
8. Formia, Caserta, Campania.—Grassy hills near the Gulf of 
Gaeta (150 ft.). 
9. Pollecca, Caserta.—Clearings among the oak woods on the 
Monti Aurunci. 
10. Villalatina, Caserta.—Meadows and thickets along the road 
which borders the Mollarino river (1,500 ft.), in the Mainarde hills. 
11. Aspromonte, Calabria, South Italy.—Clearings and meadows 
on the plateau of Carmelia (2, 000 ft.). 
12. 8. Martino, Palermo, Sicily.—Grassy dells among the bare 
slopes of Monte Cuccio and Monte Pietroso (2,500 ft.). 
I begin with 7%. transalpina, which is the most interesting of the 
Italian Zygaenae, on account of the numerous varieties and individual 
forms which it produces, and I give the data and statistics of the four 
varieties of which I possess a sufficient number of specimens. 
Zygaena transalpina, Esp. flies at the end of June or in the first 
days of July at Florence, Fontebuona, Palazzuolo, Firenzuola, Mace- 
rata, Polleca, and Villalatina; at Formia it begins to appear in 
January and flies in March ; at Bolognola it first appears in July and 
re-appears in September. It has not been found in the other localities 
above mentioned.
