S])ot. Sides groy ; on eaeb segment a large white spot, edged with blaek. Tiiese 

 spots are very irregular in shape, and on segments (i to 10 form a large anterior 

 and a smaller posterior spot, or dis'ide into three or four small spots. The first 

 segment has at its anterior edge a small black subdorsal spot, and on either side a 

 black line whicii extends to and joins the black edging of the white lateral patch ; 

 sometimes this segment is simply bordered anteriorly witli black. Each segment 

 has posteriorly four ringlets, which give the bauds an irregular appearance. Horn 

 filiform, 25 to 3U mm. long, black with two white rings, one at base and the other 

 near tip ; this horn, owing to its thinness and length, sometimes curls uj) at the 

 end like a corkscrew. 



" Underneath the colour is pale brown, almost white in some instances, having 

 on each segment a few black marks. The anal segment is pale grey, partly edged 

 with brown ; two slight excrescences on lap])ets. Prolegs yellowish, with two 

 black spots exteriorly ; abdominal legs grey, with a broad black stripe at the base. 



"The larva forms a coarse cocoon on surface of ground, and changes to pupa 

 in from 10 to 14 days. Pupa about (id mm. long, rather slight, and bearing a strong 

 resemblance to the pupae of Erinnyis, but is ligiiter in colour, with the dashes of 

 dark brown more conspicnons. The wing-cases especially are similar, but the 

 markings on thorax and head are fewer in number, the pupa resembling in this 

 respect more that of Pst'udosphinx tetrio, which has also the same shape. — Food- 

 plant : Flumeria."
