74 THE entomologist's record. 



Mont Ventoux ; Monsieur Oberthiir has very kindly sent me labelled 

 specimens of the various forms (referred to in his Lepidoptera 

 Comparci') of the transalpina, filipendulae, and lonicerae groups, so that 

 I am fortunate in having his determinations, and the majority of my 

 Sainte Baume specimens are thoroughly typical of the specimens he 

 sent me, ^vhich were taken in Var and also at Montrieux. In a long^ 

 series we, of course, find variations, and many of my specimens have 

 broad margins to the secondaries, there is, however, wonderfully little 

 variation in the spots of the primaries, there are a very few specimens 

 with largish spots, but even this is rare. The series from Mont 

 Ventoux is not quite typical. Here I took about twenty-five 

 specimens and all have the margins to the secondaries almost linear, 

 whilst the spots in the primaries are decidedly larger in all the 

 specimens, and in half of them they are more or less inclined to 

 confluence, but not to the extent obtaining in centralis-occidentalis, these 

 are a well marked group and apparently cfntralis will prove to be a 

 distinct species. In the neighbourhood around St. Martin Yesubie 

 the species belonging to the transalpina section that I found plentifully 

 was viaritiiiia, Obth., it also seems to be easily distinguishable. 



Monsieur Oberthiir kindly sent me half-a-dozen specimens labelled 

 hi/ipocrcpi'lis v. alpina — no doubt this is Boisduval's insect. Whilst 

 at bigne in 1911, and again tbe jear l)efore last, I took a fair series of 

 a Zyiiaeiia in the Dourbes mountains and elsewhere that I have 

 endeavoured to fit in with Oberthiir's examples, but I cannot make 

 them agree either in the pattern or in structure. I have dissected out 

 the genitalia of each and there are certainly two species, that is to sa_y 

 aljtina does not agree with my series from Digne, and I regret that I 

 cannot yet identify with any certainty my specimens though I hope to 

 do so later. Zipjaena fdipendnlae, Z. trifoUi, Z. lonicerae, Z. fausta, 

 and Z. carniidica will be referred to later on, but it is interesting to 

 note that at Old Nans, some 800 feet below la Sainte Baume, I took a 

 single specimen of Z. occitanica. In no place did I take transalpina 

 and centralis together, the latter in its form a'ntralis-pr()ri)icialis seems 

 to replace transalpi)ia at la Sainte Baume. 



The most interesting feature of this genus in this district is the 

 fact that at la Sainte Baume I took a fair series of filipenditlae, about 

 two dozen individuals, and that half of them are a five-spotted form. 

 I could have taken many more but did not realise that I was taking 

 two species until I came home, and even then it was only (being some- 

 what doubtful of one or two specimens) the examination of the 

 genitalia that revealed for certain what I had before me. The 

 specimens in question are rather smaller than the average six-spotted 

 filipendulae; they are somewhat thinly scaled and of slighter build, 

 generally the margin of the hindwings is narrowly black, but in several 

 specimens it is as wide as in the trifolU that I took alongside them, 

 and as a matter of fact in the first instance I placed all the five- 

 spotted form under that species, especiuily as most had not a sixth 

 spot on the underside. I took also several at Digne and one at St. 

 Martin Vesubie ; these, however, unlike the majority of those from la 

 Sainte Baume, have a well marked trace of the sixth spot on the 

 under-surface. It seems to me that we have a well marked form being 

 here developed and that it is quite worthy of a name. I therefore 

 propose to call it filipendulae var. (juithjiieuiarula, the la Sainte Baume
