1'24 THE entomologist's record. 



dorsally a large creamy wedge-shaped area, stretching forwards 

 from the nth segment so as to enclose the posterior trape- 

 zoidals which form a black patch. The nth segment is 

 creamy, with a dark marbling on the same area that is white on 

 the loth segment, and a faint dark marbled streak below. 

 The 1 2th segment is marbled in this way throughout, except 

 a creamy dorsal line and the two great black double humps 

 formed by the trapezoidals and the smaller points of the 

 supra-spiracular. Segments 13 and 14 are white with a trace 

 of black marbling. Anal prolegs blackish ; the under surface 

 is creamy white on 11, 12, 13 and 14, fuscous elsewhere. 



The 2nd segment has a plate carrying, or corresponding to, 

 (apparently) 6 trapezoidal tubercles, of which 2 pairs carry 

 spatula-ended bristles, and are apparently anterior trapezoidals, 

 though on the other segments it is the posterior trapezoidals 

 that carry the longest bristles representing the grand ones of 

 the last skin. The trapezoidals mark out an elevated angular 

 dorsal area, almost to be called a hump, and most marked in 

 5th, 6th, 7th, 8th and gth segments. In the 4th skin, the 

 length, when extended, is 16-17 mm., but it usually sits in the 

 form of a note of interrogation with the head curved round 

 against the 9th segment, the bending taking place in the 5th 

 and 6th and gth and loth segments. It eats the leaf irregu- 

 larly in small rounded patches, giving a jagged outline and a 

 ragged appearance to the leaf. 



The head is sometimes entirely black, but usually has the 

 upper portion buff with darker tcssclations. The segments, 

 from the 2nd to the gth, are black with a white porcellanous 

 lateral line fading upwards, a trace of white dorsal line, best 

 marked in 2, 3 and 4. Segments 3 and 4 are rather paler, with 

 a sub-trapezoidal whitish line, and other portions buff-coloured. 

 Traces of a sub-trapezoidal line may elsewhere be observed in 

 incisions; 11 is creamy porcellanous, invaded laterally and 

 behind from 12 with fuscous, this segment is flatter and 

 broader than the others; 12 is large and humped, with a 

 creamy white dorsal line and other markings, but the tubercles 

 are large, dark rufo-fuscous, and have fuscous clouds about 

 them, the anterior trapezoidal with short hairs, the posterior 

 with larger faintly clavate ; 13 and 14 are creamy, 13 with two 

 clavate hairs on posterior trapezoidals, 10 is dark fuscous, 

 invaded behind by creamy, up to trapezoidals, and below them 

 just to front of segment, joined by a white line between the 

 trapezoidals ; there is also a white dot at the base of the hair
