EDWARDSIA W- ALBUM. 159 



together. The prothorax has a plate, with sharp outer angles pro- 

 jecting in front, but rounded ; it has, on either side, a large lenticle 

 in front, near the middle, a hair on either side of this, and one behind. 

 These are the three hairs in front of the plate along its outer angle. 

 The lower of these, together with a fourth, might be described as in 

 front of the spiracle. The meso- and metathorax have the four flange- 

 hairs much as on the abdominal segments, with a fifth hair above 

 them, in a position nearly corresponding with the spiracles, but a little 

 more to the front of the segment. The 7th abdominal segment has 

 only one pair of long dorsal hairs (i ?). Immediately outside this is 

 a large lenticle, apparently of the series on segments in front, then a 

 hair about 0-15mm. long, on middle of segment, which can hardly be 

 the accessory from front of i, which has, however, no other repre- 

 sentative, nor is it easy to say what else this hair can be ; below and 

 behind this is another lenticle, well to the front of which, and a little 

 below, is the spiracle. This segment also has a large lenticle below 

 the four flange hairs. On the 8th abdominal segment are four large 

 dorsal lenticles, placed trapezoidally, then the spiracle, a little to the 

 front. Below it a group of six hairs, one of which is very long, then 

 a large lenticle, and then the lower pair of hairs, apparently a pair 

 here, though on the 7th abdominal there is only one. It may be 

 that, of the six subspiracular hairs, some belong to the 9th abdominal, 

 as the divisions between the 8th, 9th, and 10th abdominal segments 

 are invisible ; similarly, the two posterior of the four dorsal lenticles 

 probably belong to the 9th abdominal. The dark anal plate is 

 triangular, with two minute spots (abortive hair-bases ?). Along the 

 flange, behind this, are seven hairs — two long, three rather less, and 

 two short ones. The skin-points are numerous, black, connected with 

 each other by stellate extensions of each point, continued by fine dots 

 to extensions of its neighbours, the result being to remind one, 

 probably justly, of the points and ribs of the pupal surface (Chapman, 

 March 16th, 1907). Second instar (fullgrown): At rest, 3-5mm. long, 

 rather more when crawling. Head black ; body green, with a red 

 lateral patch on either side of the 2nd and 3rd abdominal segments, a 

 red dorsal patch on the 7th abdominal segment, and long red dorsal 

 patches on either side of the 7th-9th abdominal segments. The body 

 rapidly raised anteriorly to the 2nd abdominal segment, gently sloping 

 posteriorly to the 7th abdominal segment, the last three segments 

 forming a somewhat flattened area dorsally. A mediodorsal de- 

 pression, with a well-defined raised ridge on either side, extending 

 from mesothorax to 7th abdominal; the segmental incisions here deeply 

 cut ; the 8th, 9th, and 10th abdominal segments are somewhat 

 welded, and not distinctly divided into segments, forming a sort of 

 flat plate covered with very long spiculate hairs, with a number of 

 quite black hairs in the median line, quite at the end of the anal flap ; 

 the sides with well-defined traces of a lateral ridge. The mediodorsal 

 depression, the segmental incisions, and the lateral flange area, of a 

 deeper green than the other areas, the mediodorsal depression carry- 

 ing a red mark on the 7th abdominal ; the lateral flange 

 shows red patches distinctly on the 2nd and 3rd and 7th-9th 

 abdominal segments. The sides of the segments from the mesothorax 

 to 7th abdominal with a rather dark green oblique line, not markedly 

 developed yet into stripes, but rather in the form of a slight de-
