322 CYANIEIS. By Dr. Seitz. 



here figured (alhida) appears to occur. — Widely distributed in West China and plentiful, also in India 

 (Naga Hills). 



pryeri. L. pryeri Murr. (^83 e). ^'ery large, above with a broad dark margin, the basal area violet, in the 



(^ the disc also violet, but in the $ whitish. Underside white with 2 rows of dark 'dots near the margin. — 

 In Amurland and Japan, not rare, in June and July. The species looks on the wing like a Pierid. The 

 larva on Syringa amurensis, full-grown in June (Doekkies). This aberrant-looking form might likewise be 

 placed into a separate genus. 



35. Genus: Cyaniris Dalm. 



Delicate and slender Blues, usually with a brilliant gloss on the upperside, and a white underside with 

 small black dots, the $$ with Ijroad dark border. Head small, densely scaled, with very thin, brush-like hairs on 

 frons and at the base of the antennae. Eyes rather small, widely separated by the relatively broad frons, sparsely 

 clothed with minute hairs. Palpi thin, porrect for the length of the head. Antennae thin, mostly less than half 

 the lenght of the costal margin, with distinctly marked club. Thorax and abdomen delicate and slender, 

 the latter just reaching to the anal angle of the hindwing. Wings very delicate and thin, broad at the 

 distal margin, the costal margin often strongly curved. — The eggs strongly flattened, sunk in at the top, 

 with minute and but little projecting tubercles which are connected by a thin network. Larvae onisciform, 

 green or variegated, elliptical in a dorsal view, very flat beneath, on segment 7 a gland and on 8 two 

 tubercles. Pupa about twice as long as broad, minutely hairy, with straight sides, anteriorly and poster- 

 iorly very obtusely rounded, the mesonotum with a slight carina. The butterflies fly higher in the air 

 than all the other Lycaenini, their flight being slow and somewhat dancing, the white underside and 

 blue upperside showing alternately. I noticed of several species in China, India and Africa that they were 

 always to be found in the neighbourhood of brooks; C. albidisca I always observed swarming over the 

 water, settling occasionally on wet stones in the brook. Most species are not rare. They have several 

 broods and hibernate as chrysalis. 



argiolus. C. argiolus L. (= acis F.) (83 g, h). (^ above shining violet blue, only the apical portion of the 



costal margin being minutely edged with white. The $ has both wings broadly bordered with dark, 



the margin of the hindwing bearing vestiges of ocelli. Underside silver-white, in the disc a row of black 



parvipimda. fiiwts, some of which are elongate, and before the margin blackish shadowy dots. ab. parvipuncta Fuchs 



(irrjalus. are specimens of the second brood with fewer dots. ab. argalus Bgsir. has the black discal dots normal 



argyphontes. beneath, but the black shadows before the margin are wanting, ab. argyphontes Bgstr. has likewise no 



ckobis. submarginal spots, but the discal spots are also reduced. On the other hand, in ab. cleobis Suh. the sub- 



albocincta. marginal shadows are likewise developed to a row of distinct lunules. In ab. albocincta Tutt the dark 



Ihersaiion. spots of the underside have pale borders. In ab. thersanon Bgstr.. which is commoner in America than 



with us, the forewing above bears a thin black discocellular spot. According to the colour of the upperside,. 



which may be more metallic, more violet, etc., a further number of aberrations have been named (ab. 



dura, Idaciiia, suffusa). Several aberrational characters may also be united in one individual, which has 



given birth to names like albocinda-cleobis, pauper-lata, lilacina-suffusa, etc. Widely distributed, occurring 



throughout Europe with the exception of the coldest districts. North Africa, and Anterior and Central 



Asia; further local forms are found in a large part of India, the whole of East Asia, and North America. 



kypolcuca. — hypoleuca Koll. (83 h) is very pure silvery white beneath, the dots being very few in number, very 



ladonides. dispersed and minute, but sharply defined. — ladonides Orza (= ladon Men.) is the Japanese form; larger. 



kobei. with a slightly different blue tint, and with more black, in ab. kobei Tutt the black may be so much 



levetii. increased that the hindwing of the $ only bears a slaty blue discal spot. — In levetti Btlr. (= huegelii 



Fixs.) the border is broader, especially in the ^, the underside more grey with the dots strongly prominent; 



huegelii. this is the form from Corea and Amurland. — huegelii Moore (83 h) is a large form from Kashmir, with 



the black border broad and sharply defined; the underside with very distinct and abundant markings 



coelestina. at the margin. — coelestina KoIL (= kasmira Moore) (83 f) is a somewhat smaller form (perhaps seasonal?) 



with narrower border and beneath less prominent markings, from the same country. — Egg very flat, 



whitish. Larva green or brown, marked with yellowish white, bearing catenulate stripes on the back, on 



segment 7 a gland to attract ants; head brown. On Ivy, Ilex, Evonymus, Ehamnus, Robinia, Genista, 



Spartium, Astragalus, Eubus, Erica, Pyrus and many other plants; in Europe visited usually by ants 



of the genus Lasius; in June and the autumn. Pupa mostly fastened to the underside of a leaf, ochreous 



with brown spots and markings. The butterflies in the spring and again in July, occasionally a third 



time at the end of August and in September, everywhere common, particularly at the flowers of ivy 



and brambles. 



dilectus. C. dilectus Moore (83 f). The forewing of the ,^ without any black border, but with whitish scaling 



on the disc. ? with the base dusted with very bright metallic blue, and the black margin not very broad.
