250 THE entomologist's record. 



Epinephele jnrtina &nd (Jolias edusa fairly comnion ; there were also a 

 few Poh/ouDiiatiis icariis and Pieris rapae, and one specimen each of j\Jeli- 

 taea (lidipna, Ilai/wardia telicanus, Issoria lathonia, and Aricia astrarche 

 of the extreme calida form. In the same place on the following day 

 the same species were again to be seen, but there were several 

 specimens of It. telicaniis, and, in addition, one Euijonia polychloroa, very 

 fresh, and some large fresh males of Celastriua ar<iiolu.i. The 

 specimens of P. aegon (I call it so to avoid confusion) are mostly of 

 largish size, especially the ? s, the $■ s being of a deep purple- blue, the 

 border not very broad, and scarcely suffused, but with the nervures 

 showing blaclv at least half across the wings, and a row of black spots 

 perceptible on the hindwing ; the underside dull grey, with the white 

 band clearly visible on the hindwing, the orange band broad on the 

 hindwing, and visible the whole length of the forewing, the metallic 

 spots very distinctly marked ; the $ s have the orange border very 

 distinct on all four wings above and below, a distinct row of black 

 spots showing between this and the border; on the underside the white 

 band is generally somewhat less continuous on the hindwing than in 

 the S , but is more clearly indicated in the form of dog-toothing on 

 the forewing. 



The next day I went some short distance along the road east of the 

 town, towards the " Carceri." Here Satyrus cordula was just coming 

 out, 3 s only as yet, a few fine ? s of Celastriua argiolus with very 

 broad black border were to be seen, a few worn Nordmanniailicis, the,? s, 

 and sometimes even the ? s, without a touch of orange on the fore- 

 wing, Ritmicia phlaeas, Polijuoma egea, and TJtyinelicus lineola were 

 also in evidence, and, as if to mark the lateness of the season, one 

 Callopkrys rubi and one Euchlo'e cardamines still in good condition. 

 The two best localities, however, proved to be the cemetery road above 

 the church of San Francesco, and the north road outside the Porta 

 Pernici, down to the Piano della Pieve. It would be tedious to go 

 through the various captures of each day, which were often repetitions 

 of previous ones, and it will be more to the point to mention only those 

 of special interest, giving at the end of the paper a complete list of the 

 species observed, with their localities and dates. The 28th produced 

 on the cemetery road, amongst other species, Agriades thetis (bellargus) 

 in abundance, both sexes being very large, and in first-rate condition, 

 one 2 Lycaena tolas, very worn, which I kept in hopes of eggs, but 

 which was unfortunately let out by prying hands the same day, a few 

 worn Melitaea parthenie, evidently stragglers from the first brood, and 

 a " blue " which I took to be A. coridon ab. calydonius, about v:hich. 

 there is a good deal to be said. In this particular place I took three 

 specimens of this form on June 28th, July 1st and 2nd, respectively. 

 At this time A. thetis was fresh and abundant, but there was no sign 

 of A. coridon, which did not appear till July 22nd. On the 19th I took 

 another worn specimen on the north road, and on the 24th another, 

 perfectly fresh, among A. coridon, A. thetis being, at this time, quite a 

 thing of the past. Now in spite of all that has been written to the 

 contrary, my own theory still is that these specimens are probably 

 hybrids. The fact that they are found among both species at the 

 time of their respective emergence, seems to point in this direction, 

 and the two species are admittedly extremely close together, especially 

 in the early stages. The strongest argument against this theory, viz.,
