 165. Oxyambulyx wildei (PI. VIII. f. 3, S ; f. 4, ?). 



Ambulyx wildei Miskin, Proc. Boy. Soc. Qi(eciisl(l. viii. p. 20. d. 3o (1801) (Cairns). 



Miskiu's deserifition, tlumgh lonor^ is not jirecise enough to recognise his insect 

 with certainty. No Queensland specimens have come to onr notice ; but we have 

 of the type a photograi)h kindly sent to us by Mr. De Vis, the curator of the 

 Brisbane Museum. Similar to small specimens of sit/jsfriffilis. Foretibia with 

 a few spines. 



J. As pale as Indian substriijiUs, the submarginal line of the forewing nearer 

 the margin above and below, distinct ; the marginal area between this line and the 

 fringe brown on the u]i|ierside, grey below, only H mm. wide at R- and not 



e.\tending below W. Eighth sternite mesially lubed as in mbitriijitis, the angles 



of the lobe not acuminate, not tuberculitbrm intci-nally. Tenth ster'iite sinuate 

 mesially, the sinus deeper than in subistrigilis and the sides of the ]date more 

 slanting. Harpe (PI. XXXI. f. ",']) resembling that of scriceipeiiiim in the develop- 

 meut of the mesial ridge, which consists of two lamellae which join each other 

 distally, where they are raised into a short obtuse process which points oblii^uely 

 basad ; a distinctly raised ventral ridge as in subxlriyilig, low, extending to the end 

 of the harpe, forming a kind of crest upon the otherwise flat, spoon-shaped, distal 

 process. Penis-sheath (PL XXX. f 0) resembling that vf S"bfifr. .•t/ibstriiiilis; a 

 dentate fold at each side, the left saw-blade extending beyond the opening of the 

 sheath reaching the end of the somewhat club-shaped apical process. 



?. Mnch deeper brown than the i, even deeper in tint than the deepest- 

 colonred sabstrigilis ; tip of abdomen (long scales of eighth tergites) seal-brown, as 

 dark as tlie band of the thorax : ]ialpus, tiliiae and tarsi also deep brown. Lines 

 across forewing conspicuous, submarginal line heavy on the up|)erside ; basal patch 

 of hindwiug brownish black, bands heavy. Underside of wings burnt umberbrown, 

 almost walnut-brown, esjiecially distally, heavily marked with blackish brown, the 

 disc paler here and there; the grey marginal area of the forewing rather broader 

 than in S, the submarginal line bordering it not distinct; basal half of hindwing 



shaded over with drab. Eighth tergite not deeply incised. Vaginal plate broadly 



rounded distally; the orifice proximal, its proximal edge not prominent. 



Length of forewing : S . -^^i mm. ; ¥, oT mm. 



Early stages not known. 



Ilab. Queensland and New Guinea.. 



In the Tring Museum 1 S and 1 ? from Milne Bay, British N. Guinea 

 (A. S. Meek). 



Apparently a Papuan representative of si'-b.^lrifiilU, with the structure of the 

 sexual organs partly as in sericeijjeniii/s. A c? in the Museimi at Budapest from 

 .Stephansort, German N. Guinea, has the subbasal spot of the forewing very large, 

 and there is a rather large costal spot distally of the subbasal costal bar. 



Hill. Oxyambulyx meeki spec. nov. (I'l. I. f. 2, 6). 



o?. Allied to U. wildei. Foretibia with .Nome' spines near end. Abdomen 

 with dorsal line, no patch on eighth tergite of 6. W m gs aboce : Forewing in c? 

 grey as in sei-iceipennis, darker in J ; an oval longitudinal costal subbasal spot, 

 vestigial in ? ; interspace between the two antemedian lines olivaceous, band-like, 

 the bund almost evenly curved ; grey discal interspace strongly narrowing behind ;
