This makes the number at present known to occur 

 in Bulgaria 141, as against 110 given in Staudinger's 

 enumeration, compared with 131 known in Greece, which 

 has been much more fully explored. The Greek species 

 not yet found in Bulgaria are 30 in number, as follows — 



Fieris hrueperi. 



Anthocharis gruncri, damonc. 



Colias heldreicJii. 



Bhodocera rhamni, deopatra. 



Thccia vj-alimm, acaci.v. 



Po/i/om7natus ottomanus, thetis. 



Lyaenn hoetica, halcanica, trochihis, argus. 



Libythea celtis. 



Charnxes jasius. 



Vanessa egca, antiopa. 



Danais c]irysi2ypus. 



Erebia melas. 



Satyriis amalthca, mamurra, aorfJiusa* stat'dinus,^ fatua. 



Epincphelc ida. 



Syrichthus proto, p)}domidis. 



Nisoniadcs marloyi. 



Hcspieria nostrodamus. 



Of these the greater part will certainly be found in 

 Bulgaria, as well as about twelve which are included in 

 the list of Koumanian butterflies given by Caradja in 

 Iris, vol. viii, pp. 1-G2, as follows — 



Colias chrysothcmc. 



Thcda hetidcV, ptrnni. 



Lyr.Tua euphcmus. 



TJicsfor nogelii. 



Neptis aceris. 



Vanessa xanthomelas* l-aUmm. 



Mclitiea maturna, arduinna. 



Erehia /i'thinp)s. 



Pararge dynienc. 



The total number of butterflies which have been hitherto 

 found or which from their known distribution may be 

 expected to occur in Bulgaria is thus as follows — 



141 + about 20 of the 29 others which occur in 

 Greece = 161 + 10 found in the Danube Valley = 171. 

 Probably in the whole Balkan Peninsula something like
