werp taken, five of them in goodly numbers, but of P. vestalis Fourcr. only a 

 single example, a male. The scarcity of this inquiline in view of the abundance 

 here of its host-specie.s, Bomhus vlryinalis K., seems remarkable. Possibly the 

 altitude (about 560 feet) in a northern county may be unfavourable to the 

 parasite but not to the host. The varieties are indicated below by the lettering- 

 used in L)r. Perkins' article. 



Psithyrus campestris Panz. (^ S '• — var. /3, 2 spns. ; var. y {rossiellus K.), 

 common; var. 6 (/em?iM.s K.), 1 spn. ; var. e {franciscamis K.), 6 spns. ; var. ^ 

 {suhterraneus K.), 2 spns. (1 spn. of var. /3 has so few black hairs that it 

 seems to be almost referable to var. n; the j-ellow '•collar" is less bright in 

 the spn. of var. 8 than in those of var. y.) 5 §: — var /3, several seen. 



P. distinctvs Perez. S S '• — var. «, 2 spns. ; var. ^, in o^reat numbers ; 

 var. y, 2 spns. (Dr. Perkins records var. a from Perthshire only.) $* 5- — 

 var. «, common ; var. /y, 1 s])n. ; var. with dull yellow fringe on scutellum and 

 basal abd. segment, 1 spn. (This last resembles P. barbiitellus.) 



P. barbutellui K. S 6 '■ — No marked variation noticeable, 10 spns. 

 $5: — 1 spn. with basal abd. segment entirely black; have it dietinctly 

 yellow-banded. 



P. fjiiri'Iricolor Lep. J S: — var. j3, very common ; var. y, 10 spns.; var. 

 with abd. segments after the 2nd clothed with yellow hairs, black subapical 

 band absent, 3 spn?. ; var. with yellow hairs absent or obscured, white band 

 on abd. obscured and sooty, 2 spns. ; var. like the last, except that the band on 

 the abd. is obscure sooty yelloio, 2 spns. (The two lust appear to be melanic 

 forms of var. [i and var. y respectively.) § §: — var. «, 3 spns. 



P. rupestris Fabr. J c^ : — var. a, 4 spns.; var fi {albinella K.), common ; 

 var. y, 8 spns. ; var. 8, 1 spn. (Transitional forms were frequent in this 

 species, but very rare in the others.) 5 ? • — typical.

Vam-ssa c-album L. in Hertfordshire. — A rather worn specimen of this 

 butterfly was taken on Norton Common, Letchworth, on May 7th, visiting 

 blackthorn blossom. This seems to be the first record of its appearance in Nortii 

 Hertfordshire, and the only notice of its occurrence in the County for many 

 years. The records given in the Victoria County History are as follows: — 

 Hertford, abundant prior to 1833 (Stevens) ; Broxbourne, 3 or 4 [Stoekley) ; 

 rSt. Alban's (Field). The last two records are probably at least fifty years old, 

 but no dates are given. — Bay 1'aljier, Inglehohno, Norton Way South,

 distressing illness, on May 3rd, at his residence at Harrow Weald, ^^'e hope

 highly esteemed Entomologist in the next forthcoming numij.ir of this 

 Magazine.
