238 SPHINGULUS; AKBESIA; OXYAMBULYX. By Dr. K. Jordan. 



darker; the forewing broader, with hirger white discocellular dot and broader apical oblique line. Palpi smoothly 

 .scaled, not rough-haired. Harpe very broad, reaching nearly to the dorsal edge of the cla.sper, with several 

 short dorsal processes and two apical ones, the lower one of which is longer than in consimiliti. — Amurland 

 and Corea, rare. The $ not described and perhaps not yet in collections. 



9. Genus: S|>liiii$;-iiliis Stgr. 



A reduced off-shoot oi Kentrochrysalis. Forewing more rounded. Palpi smaller ; paronychium atrophi- 

 ed. Hind tibia with two pairs of very small spurs. — One species. 



nuts. S. mus Stgr. (37 a). Uniformly grey, with very slight markings. — Anuirland (Ussuri, Suifun. etc.), 



in June; the early stages not yet described. 



2. Subfamily: Ambulicitiae. 



Lik(: tlio Achcronii iliac alway.s witliout l)asal spot on the iiinof side of the fu'st palpal .segment, iliddle and hind 

 tarsi always without basal comb of jtrolonged bristles, this comb being present in most AcheronUinae. Tongue never 

 longer than the body, as a rule short, weak and fimctionless. Antennae never incrassate towards the ajiex, often dentate 

 '^ or even pectinate; end-segment short, except in the four genera Coiiipsoyene, 0.ryambiily.r, Protambulyx and Cypa, of which 



only Oxyamhulyx is represented on Palearctic territory. Spines of abdomen always weak, and nearly always absent on the 

 underside, only a few of the least reduced forms Uke Oxyamlulyx, Protamhidyx and allied genera have a small nundjer of sjiines 

 beneath. In the more generalised forms the forewing is slender, produced at the apex, truncate or emarginate. The outer margin 

 is often dentate, lobate, angulate or deeply sinuate below the apex, the longitudinal stripes so often occurring on the disc be- 

 tween the radial and median branches in the AcheronUinae are never present. 



The larvae are granulose, sometimes even furnished \vith such long spines as to render them similar to the larvae of 

 Sdiiirniidac {fMijlio.sk'lhii.<i. short siunes in Rhadinopasn). The hea<l is usually narrowed above, but many forms have a round 

 head, and in some spcnies it is round in the first stage and then conical. There are also genera (e. g. Clani.'i) in which it is first 

 l)()inted and later on roimd. The ini])a never has a free tongue-case: the latter never reaches to the end of the wing-cases 

 exce|)t in Compsoycna panopus and perhajis a few allied species. About 150 species are known. As many of them stand 

 rather ist)lated, we are justified in assuming that a large number of the tropical species have not yet been discovered. It is very 

 noteworthy that in South America only very few species of this subfamily occm', wlule North America and the Palearctic Begion 

 as well a-s the tropics of Africa and Asia are rich in species. The moths fly at night; onlj' a few forms visit flowers. 



10. Genus: Akbesia R.d; J. 



Tongue extending to beyond the middle of the abdomen. Palpi short, not porrect. At the upper 

 edge of the eye pendant scales (eye-brow). Antennae of cj with long seriate cilia, in the $ simply cylindrical 

 without lateral grooves and without prolonged cilia; end-segment of both sexes short. Head with a transverse 

 tuft between the anteiniae. Tibiae without spines, but fore tibia with long end-thorn; hind tibia with two 

 pairs of spurs, pulvillus small, paronychium present, but the two ventral lobes of the latter only indicated. 

 Apex of forewing pointed, outer margin slightly wavy, and somewhat convex; subcostal and upper radial 

 of hindwing stalked, radial 2 from the middle of the cell. Clasper o' cj without friction-scales on the outer 

 side. 



One species, which is most closely allied to Batocnema from Africa and Madagascar (coquereli, africanus). 



davidi. A. davidi Ohcrth. (37 b). A magnificently coloured species. Green, forewing above with light transverse 



band before the middle and brownish shadowy discal band. Upperside of liindwing with the exception of 

 the margin brownisii yellow like a large basal spot on the underside of the forewing. — Akbes in Asia Minor, 

 not rare. The early stages are not yet described. 



11. Genus: Oxyaiubulyx R. d- J. 



Tongue extending at least to the middle of the abdomen. Palpi large, porrect in a dorsal view, their 

 apical surface at almost the same level as the frons. Transversely between the antennae a sharp crest formed 

 by the scaling. End-segment of antennae long, smoothly scaled above ; antenna of $ with the indication of pro- 

 longed cilia, without the lateral grooves of the (^-antenna. Abdomen above densely spinose at the edges of the 

 segments, below with few spines, these standing at the edges of the posterior segments ; before the apex in the 

 (J on each side a pointed tuft of scales. Tibiae without spines; fore tibia without apical thorn, hind tibia 

 with two pairs of spurs, the outer spur of each pair much shorter than the inner one; at the base of the middle 

 and hind tibiae a white spot. Pulvillus present, paronychium with two lobes on each side. Forewing with 

 pointed apex. The $ on the whole darker than the (J. — Larva Avith conical head and long horn. Very 

 little is known about the early stages and habits of the moths. Many of the species are very similar, but can 

 always be distinguished by the genitalia and certain constant differences in the markings. The genus is Asiatic- 

 Australian and occurs from Japan to Ceylon and the Andamans, and eastward to Queensland and the Solomon
