DESCEIPTIONS OF SOME NEW SPECIES OF LEPIDOPTERA 

 FROM ALaERIA. 



BY GEORGE T. BAKER. 



Mr. AVm. Pech, of Budapest, who was collecting in Algeria 

 during the first half of 1884, has recently sent me a very interesting 

 collection of the Lepidoptera then taken, among which are several 

 species which have been submitted to Dr. Staudinger, and have been 

 pronounced by him to be new, these Mr. Pech has kindly asked me to 

 describe. Prom February to the end of April he worked the neigh- 

 bourhood of Lambessa, and, for the remainder of his sojourn, Guelma 

 (which is a good deal nearer the Mediterranean) was his head quarters. 

 As I hope later on to give a detailed account of his captures, I will 

 now, without further remark, describe the species new to science. 



AnTHOCHARIS PeCHI, 11. sp. 

 Aim anticce et posticm alhcB, puncto discoidali, et cum apice griseis. Ivfra, ales 

 anticcB, apice sulphureo-virescente, alee posticce sulphureo-virescentes, nigro fortiter 

 irroratce, macula centrali parva albida. 



In the S the wings are white above, the posterior ones looking slightly greyish 

 on account of the darker under-side showing somewhat through. The base of all 

 the wings is rather grejish. The apex and discoidal spot of the anterior-wings are 

 grey, the latter being the shape of an irregular paraiellograra. In the grey apical 

 patch before the tip is a small, indistinct whitish spot. The costa from the base to 

 the discoidal spot is broadly greyish. 



Beneath. The apex of the anterior-wings is greenish-yellow, finely irrorated 

 with dark grey, the discoidal spot which appears through, but faintly, is pale grey, 

 with a whitish crescent in it. The posterior-wings are greenish-yellow, more in- 

 tensely irrorated with blackish, and have a single small whitish spot in the centre. 

 The fore-part of the thorax by the head is very pale yellow. The antennae are grey, 

 tipped with lemon colour. The fringes are white, greyish by the apex. 



This description applies also to the $ , but the markings are all 

 darker, and the apical patch and discoidal spot are larger, while in the 

 former there is the faintest trace of the usual transverse spotted band. 

 The extreme apex is also slightly greenish. The ^ measures 32 — 33 

 mm. ; the ? 36 mm. 



This species, which I name after its captor, is a near ally to 

 Charlonia, Donzl. {Penia, Prr.), and will immediately precede it. Only 

 five specimens (three <^ and two ? ) of this pretty Anthocharis were 

 taken, which were caught at Lambessa in April. A ^ and $ are in 

 my collection. A. Pechi can be readily distinguished from Tagis by 

 its smaller size, and by the apex and discoidal spot being much greyer, 

 also the white spots in the dark apical patch of Tagis are wanting in 

 Pechi.
