name, and I shall here name it kirhyi. The race from the Riviera to Genoa has 

 received the name matutia Turati for its spring brood ; the summer brood I here 

 name turatii. 



The Tuscan and Central Italian race has the names romana Calb. for the 

 spring brood and romanides Verity for the summer brood. Count Turati has 

 described the Sicilian form as kruegeri and trinacriae, i.e. spring and summer 

 broods. The Grecian and Black Sea race has received the names graeca Stand, 

 for tlie spring brood and maxima for the summer brood. 



The Asia Minor race had its spring brood named crameria Butl. and its 

 summer brood taurica Rober, while Verity named the spring brood from Jerusalem 

 (Palestine) triangula Verity, and Friihstorfer described the summer brood as 

 melisamla Fruhst. The Egyptian form has for its spring brood the name 

 acgyptiaca Verity. 



The Algerian forms have been most unlucky in their nomenclature, for they 

 have received four names, all of which were given to aberrations — viz. Anthocharis 

 pechi Oberth. (nee Stand.), Euchloi' tagis mauretanica Rober, Anthocharis tagis 

 algirica Oberth., and Euchloi; belia melanochloros Ruber. Unfortunately the 

 typical Central Algerian race has received no name, so the spring brood has to 

 bear the name algirica Oberth. and the summer brood that of melanochloros 

 Ruber. The North Algerian form is the same as the Spanish. Before going into 

 details about the Guelt-es-Stel series I think it will enable my readers to 

 understand the above explanation better if I give a table of the European and 

 Mediterranean forms of Euchloi: ausonia Htibn. They fall into two natural groups : 

 1 , single-brooded, and 2, double-brooded. In all the different local races in 

 Group 2, the first or spring brood can be easily distingnished from the second or 

 summer brood by the markings on the underside of the hindwings and on the apex 

 of the forewings. In the first brood these markings are sharply defined, bright 

 grass-greeu or green slightly washed with black, brown or grey ; in the second 

 brood, on the other hand, the markings are much blnrred, ill defined, and strongly 

 washed and suffused with yellow. The table is in the nomenclatorial form of the 

 recent List of British Birds as I think it gives the best idea of the various categories 

 of forms.
