"Red, shining'; antonnae and legs testaceous, the former filiform. Length 

 4"5 mm. Build of C iminaciilafum Stepli., but larger and difTerontly coloured 

 the antennae long and filiform ; rather more obsoletely punctured and less 

 pubescent. Antennae with the 3rd joint a little longer than the 2nd, the 4th 

 to the 10th all much longer than broad but gradually decreasing in length, the 

 11th as long as the preceding.

BALKAN BUTTERFLIES. 

 BY HERBERT MACE. 



Although there is a bright displaj^ of butterflies during the summer, 

 two 3'eai's' collecting in the Balkans produced a much poorer crop of 

 species than I had expected. As a matter of fact, five species which 

 were extremely abundant, brightly coloured, and conspicuous, accounted 

 for the display. These* were the " Painted Lady," the " Clouded 

 Yellow," the "Bath White," and the two " SwaUovv-tails." 



Comparatively little freedom from military restriction was obtain- 

 able during the campaign, or I might have secured a greater number of 

 species, for the country is so broken up into more or less isolated ravines 

 that an insect might be plentiful only a short distance from the places 

 one was able to visit. 



Macedonia being at the opposite end of Europe, some comparison 

 between its species and those of Britain is interesting. Of thirty-six 

 species which are common in Britain, only fourteen are abundant in 

 Macedonia ; and of thirty-four species which I found common 

 in Macedonia, twenty-one are absent or very rare in Britain. 



In the Nymplialidae a curious feature is the absence of V. urticae, 

 accounted for by the scarcity of the common nettle ; and in the genus 

 Argynnis, notoriously local insects, there appears to be a total difference 

 in the species, not one of those I found being known (except latlionia 

 very rarely) in Bi'itain. 



Five of our British species, though common in Macedonia, appear 

 as a distinct local race. These are S. megaera, G. ^pam-philus, L. phlaeas, 

 F. astrai'clie, and A. thaumas. 



Another feature I noticed was the occurrence of extremely dwarf 

 forms of several sjiecies, similar to those produced from time to time 

 among bred specimens, which is, 1 believe, accounted for by malnutrition
