 to fly at the end of June, occurring in mountain valleys, singly but not rarely; they have a rather clumsy 

 flight and fre(|ueiit especially the beds of brooks.

 conspicuously with the brown ground, which is especially dark in the $. Central and Southern Europe, 

 as well as Anterior Asia as far as Kurdistan. — Of aberrations in the upperside we mention first the very

 panied by small orange yellow spots, which form two subdorsal lines ; similar yellow stripes on the sides ; 

 iiead black. Until April and again in the summer on Hippocrepis and Coronilla. Pupa green or brown, 

 with a dark stripe on the Idaek, on or close to the ground. The butterflies are on the wing in May and 

 June and again in August, in the South a third time in September and October. They love open places, 

 fallow ground, young plantations and sunny slopes; they rest in day-time with open wings and sleep on 

 Umbels, Thistles, and Scabious, also on stalks of grass, keeping the wings tightly closed. When disturbed 

 they fall with a jump into the grass. They are common at their flight-places in most districts and occur 

 in mountains up to 7000 ft. 



L. coridon Poda (81 c, d). ^ above light blue green with a silvery glitter, the black margin of the coridon. 

 forewing broad, the hindwing with dark dots at the margin. The underside light violet-grey on the fore- 

 wing, brownish on the hindwing, variegated with white and bearing yellowish red submarginal spots; both 

 wings very densely ornamented with ocelli. 5 above russet grey-brown, beneath earth-brown and like the 

 ^ with very numerous ocelli. The area of distribution is essentially smaller than in most Blues, being 

 apparently entirely restricted to Central and South Europe. The species occurs from England, Pom- 

 merania, and St. Petersburg southwards to Spain. Italj- and Brussa, and from the Pyrenees to Orenburg. 

 Although the species is very uniforml}' developed, quite a number of forms have been provided with 

 names, being partly based on very minute differences. We deal first with the variation of the upperside. — • 

 hispana H.-Schdff. {= arragonensis Gerh.), from Spain, is paler with the distal margin more strongly hispuna. 

 spotted. — apennina Z. (81 d) is on the whole paler, the dark marginal border of the forewing being apennina. 

 lighter in consequence of an intermixture of the ground-colour; from Italy. — The Greek form graeca graeca. 

 Biihl-Heipie is quite similar. — rezniceki Bartel, from Northern Italy, is a transition to the previous; rezniceki. 

 according to the description the upperside of the ^^^ is still paler. — albicans H.-Schdff. (81 d) is the albicans.
