S S . Differs from Leucorlmmpha in the posterior tergites of the abdomen 

 being armed with a row of alternately long and short spines. ? without prolonged 

 anal tuft ; steruite and tcrgite of seventh segment broad, truncate. Sexual 

 armature of i similar to that of Lcncorkampha ; harpe short, triangular, not or 

 little curved. 



Larva verj' peculiar (J/, jiluto, see below), in general aspect more like the 

 larva of a Catocola than a Sjihingid. First stages with long slender horn, which is 

 replaced by a short cone later on. It pupates in a cocoon attached to the stem of 

 the food-plant. At rest it does not use the first two pairs of prolegs, curving the 

 body somewhat like the larvae of Geometrulae. The stout chrysalis resembles that 

 of Fseudosphinx tetrio. 



Hah. South and Central America ; Cuba. 



Four species, which bear a close resemblance to each other in pattern and 

 colour, being all grey, with a short, more or less triangular, silvery spot on the 

 forewing, which is generally preceded by a smaller spot. The mesothoracic teguia 

 have a small black spot anteriorly, corresponding to the anterior part of the patch 

 of Leucorhampka ; the abdomen lias no pale dorsal mesial vitta as has Learo- 

 rhanijjha ; below there is a series of white mesial spots.
