16 LIMBATOCHLAMYS; TANAORHINUS; HIPPARCHUS. By L. B. Protjt. 



11. Genus: liimbatocltlam^s Rothsch. 



Palpus moderate, with third joint in ^ small ($ unknown). Antenna bipectinate with extremely short 

 branches. Hindtibia not djlated, aU spurs well developed. Abdomen not crested. Forewing somewhat falcate, 

 first subcostal anastomosing or connected with costal, hindwing with second subcostal arising from cell. Another 

 very distinct genus in fades, erected by Rothschild for a single Chinese species, which has remained rare. 



rosfhorni. L. rosthortii Rothsch. (2 a). Forewing oUve brown, the costal edge very pale brown, partly tinged 



with reddish and sparsely dotted with black, a black hne (less distinct distally) separating this area from the 

 ground colour; a postmedian Hne consisting of a row of dark dots on the veins. Hindwing paler, its ante- 

 rior half concolorous with costa of forewing; a large lunular discal mark and a thick, dentate postmedian Hne. 

 Under surface more reddish brown, speckled with black, forewing with a small discal spot and a straight thick 

 postmedian Hne not reaching the margins. Central and western China, in July. 



12. Genus : Tauaorliiuus Btlr. 



Palpus moderate to long, tliird joint in $ usually very long. Antenna in $ bipectinate. Hindtibia in 

 (J dilated, with hair-pencil. Abdomen not crested. Forewing with apex falcate, first subcostal free. Hind- 

 wing with anal angle pronounced, sometimes produced into a small lobe. Early stages unknown. The genus 

 belongs chiefly to the Indo-AustraUan Region. Except in the falcate forewing it differs Httle from Hipparchus, 

 to which it would be possible to sink it as a subgenus. 



conficckiria. T. confuciaria Walk. (2 a) is the representative in Japan and eastern to central China of the Indian 



reciprocata Walk., from which it is scarcely distinguishable except in sHghtly robuster build, sHghtly less falcate 

 apex, stronger pale markings, the postmedian more strongly dentate. Both species (or forms) are characterized 

 by the broad, dentate white lines and especially by a plain green underside Avith brown discal spot and post- 

 median Hne, and rarely, on the hindwing, a series of roundish submarginal spots. The rest of the species 

 have generally more variegated undersides, with less (or no) green colouring. 



vittata. T. vittata Moore (2 a) belongs, with argentifusa, alternata and an undescribed species fi-om New Guinea, 



to a second section of the genus, less robust in build, more glossy, with the postmedian line straight, not den- 

 tate, and with a few minor differences in structure, to which Warren formerly gave a separate generic name, 

 Mixochlora. vittata is the most common and widely distributed species, ranging from Japan to Omei-shan and 

 prasinus. throughout North India, if not also to the Malay Archipelago. — prasinus Btb\, the Japanese form, differs 

 sHghtly from the name-type in usually having the two central bands more closely approaching one another at 

 inner margin, sometimes almost in V-form. Like all the group, its markings consist of an alternation of glossy 

 green and silvery. Under surface mostly yellow, with tliick grejash postmedian and subterminal Hnes. The 

 moth appears in June and July, and again in the autumn. 



13. Genus : Hippareliiis Leach. 



This genus, which is usually known by the name of Geometra Treits. (a historically incorrect appH- 

 cation of the name Geometra L.) is also the Terpne of Hubner (nom. nud.), Holothalassis of Hubner, Lep- 

 tornis of Billberg (nom. nud.), but the name of HipparcJms Leach must be restored to it. The genus belongs 

 chiefly to the Eastern Palearctic Region and Northern India, but has as its name-type the well-kiiown papi- 

 lionaria, the finest of the Hemitheinae of Europe. 



Palpus moderate to long, antenna in (^ bepectinate, liindtibia in ^ usually with hair-pencil, always 

 with all spurs, abdomen not crested, wings ample, forewing with apex usually acute, first subcostal free or 

 anastomosing with costal, hindwing usually with a bend or small tail at the end of third radial, sometimes 

 crenulate throughout, second subcostal arising near end of cell. Some sHght variations in wing-shape and 

 structure have given rise to the erection of some imnecessary genera — Megalochlora, Loxochila, CMoroglyphica, 

 Hydrochroa — which are here merged in Hipparchus. 



The early stages of papilionaria are well known, and are briefly described below, but information is 

 stiU wanting as to those of most of the species.
