(?. Extornal sjinr of midtiliia sliortor tlian intonial : liindtHiia of S long-scaled 

 (lortially and veutrally, conseqnently appearing very broad and compressed. Dark 

 brown middle line of mesothorac.ical tegnia continued to palpns ; abdomen with an 

 ochraceons middle line bordered by thin grey lines, a brown lateral line bordered 

 below by a pale bnft' one on segments :3 to 7. Hinder angle of forewiug extremely 

 oljtnsi' : discal line 1 not distinct, within a chocolate-brown area, which is bordered 

 distally by a white line upon SO* and posteriorly by discal line 2 ; discal lines 

 3 and 4 close together, 5 broad from apex to R''', then vestigial, 6 parallel to 



margin, obsolete beliind ; interspaces between 2 and 4 pale, more or less buff. 



Hiudwing uniform in colour, with traces of two series of discal vein-dots. 



Viulersidi' : the brown marginal area of the foi'ewing joined to discal area 

 between R^ and R^ ; three or four discal lines, more or less abbreviated in front, 

 3 and 4 merged together behind and bordered hero distally by a creamy buff line ; 

 costa more or less yellowish buflf at apex. Distal marginal area of hiudwing 

 irrorated with creamy buif and brown scales, with the former especially before M- ; 

 three discal lines, the tirst abbreviated, often absent, the other two close together, 

 reaching R' or SG^. 



S. Tenth abdominal tergite truncate-sinuate, of the usnal form; steruite also 

 not differing from that of the allied species, minutely pointed in middle. Process 

 of harpe slightly spatulate, feebly curved upwards at end. Incrassate dorso-apical 

 margin of the jienis-sheath terminating at the right side in a dentate process, 

 which is preceded by a few teeth ; at the left side the sheath bears a regular 

 row of teeth. 



Early stages not known. 



Ihili. Neotropical Region : Guatemala to Kio de Janeiro and Peru. 



Though the present insect was well figured by (Uerck and recognisably 

 described by Linne as thijelia, this name has been applied to a very different insect 

 of the Indo-Anstralian fauna by all recent authors, who, blindly following Fabricins 

 and AValker, did not trouble to compare LinnS's description or Clerck's figure.

CLIV. PHANOXYLA gen. uov.-Typus : h,iAtrlx. 



S . Differs from Xi/loplianes in the second segment of the palpus having a large 

 ajiical tuft of scales on the inner surface as in HIppotioii. Distal margin of fore- 

 wing irregular, excised between R- and M'. 



Palpus and eye large. No eye-lashes. Comb of midtarsus prominent. Spines 

 of posterior abdominal tergites uniseriate, strong and long, with some weak spines 



between them. Sexual armature similar to that of Xylophanes ; friction-scales 



very Numerous. 



Early stages not known. 



I]<(,b. Neotropical Region. 



One species. 



An exaggerated development of the grou]) of Xi/lopltancs to whicb belong 

 ccrfitoinioides, vwdia, etc. The species is of particular interest, as the second segment 

 of the palpus is on the innerside as in some Old World genera, while the lirsf. 

 segment is like that of the New World genns Xylophanes.
