 Islands to Sontliern Hra/il ; not known from Argentina, but occurring doulitless in 

 the northern parts of the Uepulilic. — Cloiumon.

M'-.'. Protambulyx carteri spec \w\ (IM. LXVI. f ?, -. LXVII. f. Vi, S). 



S- Agrees structurallj- with A. striijilis \ but, differs in the following points: 

 obliipie lateral lines of abdominal tergites and lines of steruites absent or very faint. 



Wings, Kjiperside. Forewing broader, apex less deeply sinuate ; disc with one line 



only, beginning at olive costal patch which stands between cell and subcostal fork, 

 a second discal line barely tracealJe ; no submarginal line and no marginal band, 



but extreme edge of wing purple-brown. Hindwing tawny as in ab. rubripennis 



of strigilis ; traces of two discal lines, the intermediate line being absent, brown 

 marginal band vestigial in ujiper half, rather better marked behind. 



Vndersific of wings very uniform in colour, similar to upperside of hindwing ; 

 first discal line vestigial on both wings, no other markings ; forewing somewhat 

 yellowish at base behind cell. 



Ilah. Bahamas and Florida. 



In tlie Tring Museum 1 S from Nassau, Bahamas, caught by Sir Gilbert 

 Carter, in whose honour the species is named. A second S from Biscayne Bay, 

 Jlorida, sent for identification by the Kny-Scheerer Company. 



We are not sure that this insect is distinct ; it may be a subspecies of striyilis ; 

 but as the latter occurs all over the West Indies and Central and South America, 

 without being sjilit up into geographical races, it would be very remarkable if (and 

 is surely not probable that) it forms a special geographical race on the Bahamas 

 and in Florida. We expect strigilis to occur in these localities as well, and believe 

 that carteri is independent of it. The absence of structural difierences is no proof 

 of the two being specifically the same. In AmjAi/pterus gcumasciis and ypsilon we 

 do also not find structural differences.

Differs from Frofavi})uhpr as follows : 



i ?. Frons almost vertical, forming an obtuse angle witii the tcrminnl surface 

 of the palpi, the latter projecting more than in Protumbidi/x. Antenna longer and 

 stouter, end-segment s/tort, barely twice as long as basally high, compressed, 

 obtuse, with a brush of long scales which project far beyond the end of the segment, 

 no long sensory bristles on end-segment, but ciliae long and densely together. All 

 tibiae mucli shorter than the rcsjiective first tarsal segments, with or without
