118 THE entomologist's RECORD. 



Perhaps the most important point to note about them is their' 

 occurrence in the last instar. In Hesperia proto and Nisoniades tages - 

 only ordinary hairs are found in the last instar, though in the latter ■' 

 species trumpet-hairs occur earlier, whilst in Thymelicus acteon hairs are ' 

 practically absent. In Hesperia malvae most of the hairs are ordinary " 

 looking, but slightly expanded and bifid at the tips, a not uncommon 

 form of hair, but clearly tending slightly in the direction of 

 " trumpet " structure. 



Spanish forms of Polyommatus corydon. 



By W. G. SHELDON, F.E.S. 

 One of the most interesting species occurring in the Albarracin 

 district is Polyommatus corydon. Zapater and Korb's list gives the 

 following forms and remarks respecting abundance : " Corydon type, 

 common ; var. albicans, rare ; var. corydonius, not rare ; var. hispana, ■ 

 not very common." Dr. Chapman says {Ent. Record, vol. xiv., p. 

 119) that " he only took var. corydonius and var. hispana, and that no 

 intermediate specimens were observed." This observation does not 

 agree with my experience. I found in the Guadalaviar Valley, hispana, 

 common, two or three corydon type, undistinguishable from my Surrey, 

 Dauphiny and Swiss specimens, and one example of var. corydonius. 

 At Losillo, again var. hispana was common, and one or two specimens 

 of corydon type were netted each day, and the series brought back 

 from that locality contains intermediates between the type and var. 

 hispana. At Noguera, neither corydon type nor var. hispana were seen, 

 but only var. corydonius, with a purple tinge, and certain examples 

 of as dark a blue as those, but without the purple tinge, that is to say 

 the same blue as corydon type, but much stronger in tint ; I thus get 

 the following forms : 



1. An almost white fonu = var. hispana. 



2. Intennediates between var. hispana and corydon type. 



3. Corydon type. 



4. A fonn with the tint of blue as ia corydon type, but much deeper and 

 stronger = intennediate between corydon type and var. corydonius. 



5. Corydonius type, resembling specimens in the British Museum, so labelled, 

 and taken in Asia Minor, but with pxirple tiat not so pronounced. 



I take it that either the species has changed in the numbers of 

 specimens of its different forms, since the days when Zapater and Korb 

 made their observations, or that they confused them, for corydon type 

 is now certainly not common, as stated by them, whilst var. hispana 

 which they describe as not very common, is now most certainly 

 abundant, in fact, by far the most abundant form found at Albarracin. 



Notes on Coleophora solitariella, C. pyrrhulipennella, C. laricella, 

 and C. albitarsella. 



By HENEY J. TUENEE, F.E.S. 

 Coleophora solitariella. — "While searching along one of the few 

 remaining lanes to the south of Lewisham, the lanes and hunting- 

 grounds sacred to the memory of Stainton, Douglas, and MacLachlan, 

 I met with this species on May 8th, 1904, feeding on Stellaria holostea 

 in a very sheltered position, below bushes and undergrowth, which 

 were beneath trees. Of the 17 cases found, all but one were small,
