810 THE entomologist's record. 



sunshine. I have not observed them basking in the sunshine in the 

 way that other species do, but have repeatedly seen them on the 

 bramble flowers. Copulation invariably takes place in the afternoon, 

 from 3.30 p.m. onwards. One pair I watched closely, and carefully 

 noted the time. At 3.30 p.m., on the afternoon of the 27th, a 5 settled 

 on the ground within a yard of me. A <? quickly followed, several 

 short, quick flights by the ? then took place, she was closely followed 

 by the g- , but was never allowed to come too close. This sort of thing 

 went on until 3.46, the g gradually getting closer to the ? every 

 minute. At 3.50, copulation had taken place. The 5 then flew to 

 the nearest birch and hung from the underside of a leaf. They 

 remained in this position until 5.35 when they separated. Whether 

 they would have remained paired longer than this I do not know, as 

 luck would have it, this pair, in which I was so interested, were rudely 

 disturbed by a small boy dashing into this very birch. The sudden 

 shock may have separated them too soon. I heartily cursed this boy. 

 I saw several pairs in cop. on other days, but never before 3.30 in the 

 afternoon. Most of these pairs were closely followed by a second g , 

 even after copulation had actually taken place. This species does not 

 Qy freely unless the sun is shining very brightly. I hoped to see the 

 female ovipositing, but was never fortunate enough to do so. A second 

 locality for this species was discovered at Mynyddislwyn, on August 6th. 

 They were flying in numbers in an old quarry, and on the sides of the 

 reservoir. This species was seen on the wing until September 5th, al- 

 though by the end of the first week in August most of the specimens were 

 in a very passe condition. Epinephele janira, Linn. — Very common 

 throughout the district. Specimens in which one or more of the wings 

 are of a dingy white are not uncommon. First specimens taken July 

 4th. Coenonymi>ha pamphiliis, Linn. — Very common throughout the 

 district. CallopJiri/s ruhi, Linn. — Common at Pentwyn and Penyfan, 

 not noticed anywhere else. Faimicia phlaeas, Linn. — Very common 

 throughout the district. A specimen, which was without the red band 

 on the hindwings, was taken on the railway bank at Abertillery, on 

 August 26th, 1905. Polyommatus icarns, Eott. — Common at Crumlin, 

 Pont-Llan-ffraith, Llanhilleth, and Mynyddislwyn, but only occurs 

 sparingly in other parts of the district. Agriades corydon, Fabr. — 

 Very rare ; a single specimen was taken at Abertillery, on August 26th, 

 1905. It was a male in good condition. I have thoroughly searched 

 the district for this species, but have failed to find another. The 

 specimen taken was probably a straggler from some other district. 

 Celastrina arf/iolus,Ijmn. — Notcommon; two specimens only taken. One 

 at flower of holly, at Pentwyn, on June 7th, 1906, and the other along 

 a shady path in a wood at Llanhilleth. Specimens of the second 

 brood were looked for, but none were seen. Both specimens taken were 

 ? s. Nisoniades tages. — Not common ; two specimens only, in poor 

 condition, taken at Crumlin, July 5th. Hesperia malvae. — Not common ; 

 one specimen only seen at Llanhilleth, on June 9th. Adopaea thaumas, 

 Hrifu. — Very common in the open spaces of the Llanock Wood, Crumlin. 

 They occur here in hundreds. Not seen elsewhere throughout the 

 district. First specimen taken on July 11th. Auyiades sylvamis, Esp. 

 ■ — Very common throughout the district. This completes the list of 

 the species taken. A careful search was made for the following species, 

 but without success — Aporia crataegi, Leucophasia sinapis, Colias
