Larva very peculiar {^J. pluto, see below), in general aspect more like the 

 laiva of a Catocola than a Sphingid. First stages with long slender horn, which is 

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

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

 body somewliat liice the larvae of (ji'oin.i'triilde. The stout chrysalis resembles that 

 of Pseud OS jjhinx tetrio.

Four species, which bear a close resemblance to each other in iiattern mihI 

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

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

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

 of Leurorhainpha ; the abdomen has no pale dorsal mesial vitta as has Lcuco- 

 rhainplui ; below there is a series of white mesial sjiots. 



Key to the species :
