M. Danais chrysippus chrysippus Linn. 



1 c?, South Oned Mya ; 1 ?, north of A in Gnettara ; 1 cJ, Igostcn, Tulikelt. 



This species occni-s in two distinot forms thron^jhoiit the larger jiortion of its 

 range, wliich again have two suhdivisions. Tiie one, l>. c. cliri/sippus, form, dimorph. 

 clin/.vpjiiia Linn., has tlie apical two-fifths of forewing black with a white band and 

 white s]iots, and among these occur speeiraens with white or whitish discs of the 

 liindwings = ali. <il('iiijjiig Falir. ; tlie second form is form, dimorj)!!. i/ori/'/>i/s King., 

 wliich has the apical two-fifths brownish fulvous yellow like the rest of the wing, 

 and again among these specimens with white or whitish discs to the hindwinga 

 occur: they are ab. aMii/nx Lanz. J). c/in/.vppii/< r»,i\geH from the Canary Islands 

 and Marocco to South Japan in the north and from (!ape Colony to Australia 

 in the south ; east of Aden the dark ab. loc. ci-fifippu.s Feld. is found among the 

 tyi)ical form more or less abundantly. 



This is the first record of the species for Algerian territory (it can hardly be 

 called Algeria). 



[Tlie above-mentioned specimens were all that we saw. except one more in the 

 bi'd (if the Oucd Mya, on May ',', which wc could not cafcii. — K. H.]

II. Pyrameis cardui cardui (Linn.). 



1 ?. Bordj Chegga; I ?. north of Am (luettara. 



This ubicpiitons sjiecies inhabits the whole world with the exception of South 

 America. It is subject to little variation, and in si)ite of the enormous extent of 

 its range can only be split u[i into three subspecies : /'. r. ranlni, whole range 

 excejrf, Arctic Regions and East Asia; P. c. pallida Schoyen, with pale yellowish 

 red ground colour, Arctic Regions ; and P. cjaponica .Stichel, which is distinguished 

 bv Mie absence or reduction in the round subrnarginal spots of the liindwings and 

 reddish ochre ground colour, East China and dapan, 



[Common in the northern portion of the Sahara in Feliruary, and now and then 

 seen as far south as Ain Gnettara. — E. H.] 



[/'>/ramei.i ufalanta (L.) was seen in Biskra several times in Marcli I'.tll, 

 and this year I observed one on the road close to the market-iilace in Touggonrt, 

 on March 1st.— E. H.] 



r,'. Melitaea didyma deserticola Obertl 



^.") (J(J, 5 ? ?, Bordj Chegga to Ivef-el-Dor. 



M'litam duli/ma is the most variable nyniphaline butterfly in the world. It 

 i-auges from Portugal on the west to the Pacific Ocean on the east, and from North 

 Europe aud Siberia in the north to the Central Sahara in the south. (It probably 

 extends right across the Sahara.) 



Up to the present expedition this race of didi/ma was the most distinct from 

 the type, being palest in colour, aud had the greatest reduction in the size and 

 number of the dark markings. One 6 in the present series has the groinid colour 

 rufous yellow, thus appearing much paler than the rest ; the type came from 

 Biskra.'
