240 POLYPTYCHUS; MARUMBA. By Dr. K. Jokdax. 



lineaia. L. lineata Westw. (37 c). The apex of the palpi and the frons blackish; the maize-coloured longitudinal 



stripe of the forewing narrow. Larva green, head white, horn and legs pink. — From North China (Shan- 

 tung) to Ceylon and eastward to the Philippines and Celebes. 



ernittens. L. emittens Walk. (= bicolor Bull., damascena Bull.). Frons and apical surface of palpi not blackish, 



but of the same red colour as the occiput and the pronotum. The maize-coloured stripe of forewing broader 

 than in lineatn. — Widely distributed in India, extending into the Palearctic Region in the North-West. 



14. Genus: Polyptyeliiis Hhn. 



The species belonging here are so very numerous in Africa and show such considerable differences that 

 later it will probably be necessary to divide up the genus. In the Asiatic (nomenclatorially typical) Poly- 

 ptychus the tongue is yellow, very weak and so short that when unrolled it does not reach to the tip of the fore 

 coxae. The antennae of ^ and $ with lateral grooves and prolonged cilia. Tibiae spinose, hind tibia with 

 two pairs of spurs which do not bear spines; pulvillus and paronychium present. Forewing with strongly den- 

 tate outer margLn. Inner margin distally deeply incurved, so that the hind angle projects backwards. Abdomen 

 above with very numerous weak spines on the surface below the scales and stronger spines at the edges. — Larva 

 green, with two greenish yellow dorsal longitudinal stripes, whitish oblique lateral stripes and conical head. Pupa 

 glossy, cremaster fairly smooth, with two points. 



The two Indian species extend into the Palearctic Region. 



P. trih'neatus. Varies from blackish brown to yellowish grey, and is shaded with violet grey. Forewing 

 with a straight dark transverse line in the basal fourth, followed by a rather irregular line, on the disc two lines 

 which raw about parallel with the outer margin, the imier one straight, the outer one curved outwards below 

 the middle. Hindwing above with faint discal line and at the anal angle a bluish grey spot. Beneath paler 

 than above, both wings with one or two distinct discal lines. Genitalia complicated and unique, varying strongly 

 Irilineatus. geographically. For larva cf. above. Known from Ceylon to China, the Philippines and Celebes. — trilineatus 

 Moore. The inner discal line of the forewing touches the lower angle of the cell and is therefore much more 

 proximal than in the other subspecies; the outer line correspondingly shifted proximad; between the two lines 

 no dentate line. Beneath the proximal discal line is absent. North-West India, at the boundary of the Pale- 

 undatus. arctic Region, only one specimens (9) known. ^ — undatus R. <& J. (= dentatus IFf/7^., nee CV.) (37 c). Proximal 

 discal line of forewing distant from the cell. Both wings beneath with two transverse lines between the cell 

 and the margin. Between the claspers of the ^ and firmly united with their bases there is a single long process 

 like a fish-tail. The eighth abdominal tergite of 9 has a large pointed conical hump on each side, and behind the 

 vaginal orifice there is a very large almost straighthly truncate chitinous sclerite. North India and Burma. 

 chincnsis. This form is figured here, because we have only one imperfect specimen of the following race. — chinensis 

 R. <& J. A '^ from China collected by natives; the wdngs are cut straight with a pair of scizzors, probably 

 because the margins were torn. Somewhat greyer than utidatus; upperside of middle and hind tibiae lighter. 

 The eighth abdominal tergite bears a large chitinous sclerite which projects from the scaling and is deeply 

 incised in the middle. The postvaginal sclerite is not truncate as in undatus, but broadly and deeply sinuate 

 in the middle. 



(letit(ili(.-<. P, dentatus C'r. (= timesius Stall, modesta F., denticulatus Hears.). Ashy grey, the two discal lines 



of the forewing parallel, the outer one not excurved below the centre, between them a distinct dentate line. The 

 sole-shaped clasper of the ^ bears a bipartite harpe; the lower process of the latter very long, thin, horizontal, 

 not as in P. trilineatus fused with the corresponding process of the other clasper. The eighth abdominal ter- 

 gite of 9 at the margin twice sinuate, therefore tripartite. Vaginal sclerite also quite different from that 

 of P. trilineatus; the orifice postmedian; beyond it a small triangular sclerite; the vaginal sclerite incrassate 

 before the orifice and the edge of the orifice raised and smooth. — Larva on Cordia; not described; for 

 the pupa cf. above in the generic description. — From Ceylon to Calcutta and Kurachi, and in China. The 

 single specimen from Tse-kou which 1 saw in coll. Ch.\rles Oberthue differs somewhat from Indian specimens. 



15. Genus: Hariiiiiba Moore. 



Differs from Polyptychus particularly by the absence of the proximal pair of spurs on the hind tibia. 



Tongue always very weak, the two halves quite separate and reduced to small lobes. Antennae in both 

 sexes with prolonged cilia; end-segment short. Abdomen above without broad scales, denselj' clothed with 

 thin spines. Tibiae spinose; tarsi stout, the spines of one row of the underside more or less erect in comb-shape.
