c? ? . Eye very large, not lashed, diameter about one and a half times the 

 width of tlie frons. Palpus slender, smooth-scaled, closely appressed to head, 

 ])ointed, not jn-qjectlng, ontline in side-view following the curve of the head. 

 Antenna distinctly clubbed, end-segment very long, filifoim, except at base, 

 ]>enultimate segment shorter than vertically broad. Abdominal spines heavy, in 

 one row, long and short ones alternating on posterior tergites, contignous, the 

 spines of the steraites also very stiff; seventh sternite of ? broadly trapeziform, 

 without spines. Merum of midcoxa angulate. Tarsi short-scaled, long ; midtarsus 

 without comb. Distal margins of wings entire ; apex of forewing acute ; R of 

 hindwing before centre of cell, hinder angle of cell acuminate, W and M' rather 

 close together, D^ being only one-fifth to one-third the length of D''. 



S. Seriated ciliae of antenna very short. Scent-organ of forecoxa largo or 

 small. Tenth segment divided, of tiie same type as in PseMflosphinx, roclniUn, 

 Erinnj/is, etc. ; the lobes of the broad tergite (PI. XLII. f. 2. 3) broad, about half 

 the length of the segment, the sinus between them wide, rounded ; sternite with 

 two long and slender processes (A'i>), which are pointed and distally curved. 

 Clasper very large. Penis-sheath (PI. LIIL f. 13. 14) forked, with apical sense 

 hairs and short tooth-like spines resembling those found in Xi/crn/x, Perigonia, 

 etc. ; ])enis-funnel produced into a long, more or less clubbed process, whieli is 

 denticulate on the upperside. 



?. Vaginal plate triangular; orifice proximal and mesial; no obvious arma- 

 ture. Eighth tergite membranaceous mesially from a]iex to near base. 



Early stages not known. 



Hub. Central and Soutli America, from Honduras to Bolivia and Southern 

 Brazil, extending probably to Mexico.

 W as the interspace between this area and 

 the first discal line (outside cell) . . 3(>0. O. kndem. 

 Distal marginal area very much narrower than
