THE ENTOMOLOGIST S RECORD. 



— Croydon. A. zephyrana. — Brockley, East Greenwich. A. badiana. 

 — Swarming in July amongst burdock ; Greenwich marshes. Cochylis 

 francillmia. — Burnt Ash Lane, Lee. C. dilucidana.- — Box Hill, 

 Brockley. C. smeathmanniana. — Greenwich marshes. C. stramineana. 

 — Brockley, Lee. Aphelia osseana. — Box Hill, Croydon. Tortricodes 

 hyemana. — Wickham, Shooter's Hill. 



My list of Tineina was a very long one for the London district ; 

 but having parted with the specimens, and unfortunately lost my 

 records. I cannot now deal with them. 



Variation of Polyommatus astrarclie, Bgstr., in Durliam. 



By J. W. H. HAERISON, B.Sc, P.E.S. 



There seems to be a great need amongst entomologists for some 

 arrangement of the varioixs forms of P. astrarche as known to us in 

 Durham. Very few seem to have a definite idea of what is included 

 in P. var. salmacis, Stphns., and I have more than once been asked 

 for a series of salmacis, "white-spotted ones preferred." A request 

 like this seems to ignore entirely the fact that Stephens, in his 

 original description of the form, expressly stated that the males of his 

 new variety did not possess the white spot. The true explanation of 

 this confusion is, as I explained in my paper on this species in the 

 Ent. Bee. for November, 1905, that, as originally described, P. var. 

 salmacis is not a form that can be deemed a recognisable variety. In 

 these few notes, while retaining the name salmacis for part of what 

 Stephens included under that name, I shall endeavour to limit it, so 

 that we have at least something definite and connected as the male 

 and female forms of the variety. Incidentally, I shall include a 

 description of all the forms I have taken in Durham which admit of 

 classification : — 



1. Both sexes above : dark iridescent fuscous; forewings with a black discoidal 

 spot ; both wings with a series of deep orange spots close to, and parallel to, the 

 posterior margin. Below : male, greyish-brown ; female, a warmer more decided 

 brown. Ocelli with black pupils arranged exactly as P. icarus var. icarinus = 

 P. astrarche, Bergstrasser. 



2. As in P. astrarche, except that the black discoidal spot is surrounded with 

 a white ring = ab. albiannulata, n. ab. 



3. As in P. astrarche, except that both sexes have the black discoidal spot 

 of the forewings replaced by a white one. Females with the row of red spots 

 normal on both wings. Males with the row becoming obsolete, more especially 

 on the forewings = ab. salmacis, Harrison (var. salmacis, Stephens, in part). 



4. As in P. var. salmacis, but the ocelli beneath without the black pupils = 

 ab. artaxerxes. Fab. 



5. As in P. var. artaxerxes, but in addition the hindwings also possess a white 

 discoidal spot = ab. quadripunctata, Tutt (I have never seen this form in Durham). 



6. As in P. ab. quadripunctata, but with ocelli with black pupils = ab. suh- 

 quadripunctata, n. ab. 



7. As in P. astrarche, except that the row of red spots above is becoming 

 obsolete = ab. semi-allous, n. ab. (var. salmacis, Stephens, part). 



8. As in P. astrarche, red spots obsolete = ab. allous, Hb. (I took one of this 

 form on July 14th, 1906), 



9. An underside form almost parallel with ab. obsoleta of other Lycsenids, and 

 ab. persica of icarus = ab. vedrae, Harr. 



10. A small form, with underside of alight silvery -grSy colour; ocelli becoming 

 obsolete ; basal ocelli reduced to two = ab. inclara, Harr. 



11. A normal-sized form, underside colours normal, but ocelli (especially close 

 inward from the white median dash) becoming obsolete = ab. semi-vedrae, n. ab. 



12. Above, fringes brown otherwise normal ; beneath, of a rich warm brown,
