290 JOLOUS; JAMIDES; POLYOMMATUS. By Dr. A. Seitz. 



hindmargin of the forewing. It might i)erhaps be better to place T'. livia as well as the following genus 

 J olaus araong the Thecliyii in the neighbourhood oiDeudoryx and Rapala; they are also related to Myrina, 

 which is strongly represented in Africa, but we wish to avoid as much as possible great alterations in the 

 arrangement to which collectors are accustomed. 



Head proportionately thick, with broad frons and flat eyes. Palpi of medium length, obliquely 

 erect. Antennae short, with thin shaft and strong pyriform club. Thorax robust. Abdomen of both sexes 

 very short, especially in the (^. Forewing triangular, with pointed apex and almost exactly rectangular hind 

 angle; hindwing w-ith small rounded anal lobe and above it a thin tail. Subcostal of forewing 4-branched. 

 lima. V. livia Klug {11 g). ^J above bright orange-red, the forewing with black-brown outer margin. $ 



above very much like Pol. haeticus, black-brown with blue gloss. Underside ashy-grey in Egyptian spe- 

 cimens, more yellowish grey to claj^-colour in specimens from South Arabia and East Africa; across both 

 wings darker shadowy lines; the anal area of the hindwing glossy blue, slightly metallic. — The butterflies 

 are not plentiful. I found the t^,^ especially often on the twigs of tamarisk, while I met with the $$ 

 generally in the neighbourhood of Acacias, so that it appears probable that the larva feeds on this tree. 

 In Egypt, Arabia, East Africa, only in hot, arid, stony districts, apparently on the wing all the year round. 



24. Genus: JTolaus Hfen. 



Also this genus is allied to the Theclini, the hindwing bearing very long tails; in facies much 

 resembling Tajuria, with which it also agrees closely in structure and with which it is united by some 

 authors; however, in Tajuria the second tail of the hindwing is not so much longer and broader than the 

 than the upper, often the inverse being the case. ^loreover, the body of Jolaus is weaker, although 

 they are good fHers. They recall in habits Deudorix, resting like these at the tip of twigs of bushes and 

 facing alwaj's towards the clearing. Eather strongly represented in the tropics, but only one species 

 touches the Palearctic Region. 

 jordanus. J. jordanus Stgr. {11 g). Beneath similar to helms, which is typical for Jolaus; Hke many allied 



African forms white, with dark lines recalling Thecla. Above similar to Tajuria lutulentus, blue, with 

 darker apical area and outer margin on both wings. — In the Jordan valley, in August and September. 



25. Genus: Jamicles H6 



n. 



This genus agrees already closely with the next; it is the first of the true Lycaenini and contains 

 only one very widely distributed species. The bright blue upperside, which is more intersely blue than in 

 any other allied genus, easily distinguishes it from La7npides, with which it agrees in the shape of the 

 wings, the markings of the underside and above all in habits. Head small, body delicate, abdomen long 

 and slender. Antenna long, thin, with the club elongate and somewhat bean-shaped. Wings broad, with 

 the distal margin rounded; hind angle of forewing almost rectangular. Hindwing with a long hair-like tail. 

 The larva on Papilionaceae, on which Gheen saw the $$ deposit the eggs. 

 hochus. J. bochus Cr. {11 g, h). Above of a magnificent bright steel-blue, the forewing with the costal 



margin and apex black. Underside brown, with numerous thin pale comma-streaks. Widely distributed; 

 from Kashmir throughout the Himalayas to Central China, and from India south- and eastward to For- 

 mosa and Australia. — Larva almost exactly like that of Cata'chrysops pandava (see p. 292), olivaceous, 

 minutely hairy, Avithout the russet tint which is usually present in the larvae of C. pandava; on Xylia 

 dolabriformis and Butea frondosa, especially at the flowers. Pupa exactly like that of Cat. pandava. The 

 butterflies occur in places with a rich vegetation all through the year, flying on sunny road-sides, where 

 the glitter of the metallic blue can be perceived from afar. They settle on the tips of twigs always 

 with the wings tighlty closed and visit flowers of all kinds. They are common in localities with abundant 

 rain, q,^ and $$ have the same habits, both sexes being easy and swift fliers. 



26. Cienus: Polyoiiimatus Latr. 



Differs from the preceding genus in the much duller blue gloss of the upperside, in the brighter 

 and more abundant markings of the underside, the shorter antennae, stronger and harder wings, more 

 robust body and in the more pointed anal angle of the hindwing. Head small, with narrow frons. Palpi 

 rather long, porrect, scaled bluish white. Thorax robust. Abdomen slender. Forewing more pointed than 

 in Jamides, with the hind angle much more obtuse. Some species are excellent fliers, which rush about in 

 a whizzing flight and occasionally congregate in swarms. They are very fond of flowers and damp places 

 on roads and in warm districts are on the wing all through the year. The larvae have the usual shape of 

 Lycaenid larvae; on Papilionaceae. The pupa smooth, yellowish brown, marmorated with dark. The 

 butterflies exhibit sometimes seasonal dimorphism. 



While many authors unite this genus with the altogether heterogeneous Tarucus and Lampides, 

 others split it up so much that each of its species is placed in a separate genus.
