from its front margin, marking off the wing base (or patagium ?). 

 It points to, but does not (by 0'7 mm.) reach the notch formed by 

 the forward lateral extension of the metathorax, each half is about 

 1*2 mm. wide, 0*4 mm. long in middle line, 1"0 mm. at lateral forward 

 extension. These portions of the thorax are smooth, with very 

 minute tessellations. One minute hair is detected on mesothorax 

 perhaps 0*05 mm. long — there are probably others. 



The first abdominal segment is about 0'6 mm. wide (1*0 mm., 

 with intersegmental membrane, after dehiscence). It has no marks, 

 spines or j)rocesses, it probably has a hair or two, but they are not 

 detected. The second abdominal segment is 1"3 mm. wide (with 

 intersegmental membrane). Its s^^iracle lies in a hollow at its front 

 outer angle, the hind-wing is slightly waved to make room for it, 

 and there is a walled ridge round it internally and behind. Right 

 across the front of the segment is a dark line in which it is just 

 possible to believe one sees small elevations of obsolete spines, the 

 more as their places are marked by dark lines radiating into the 

 general surface; posteriorly, is a just discernible line. Each side 

 carries three hairs (about 0"1 mm. long), one below and behind 

 spiracle in the hollow with it, one just above inner front margin of 

 hollow (III ?), and one nearer the middle line, a little behind spine 

 ridge (i ?). The third abdominal segment is larger than the second. 

 The spiracle is on the smooth surface, both lines have spines well 

 developed, the upper one reaches almost as far out as spiracle, the 

 posterior rather less. On the next (fourth) segment the front row 

 goes ten spines ventral of sj^iracle, the posterior much as on third. 

 On the fifth the front line reaches for about twelve spines ventral of 

 spiracle, the posterior much the same as previous segment. On 

 these the front row comes to margin of lateral flange, on sixth it goes 

 well on to it, as also on seventh. On eighth it is only just below 

 spiracular level and on ninth a little lower. The posterior row on 

 6 is much as on fifth. No trace of it on 7, 8 or 9 (probably like other 

 species it exists on seventh in ^ ). On third to ninth segments the 

 dorsal hairs (i and iii 1) exist, getting on fifth very close to the row 

 of spines and on the following ones almost on it. On third and 

 fourth segments is a hair below the spiracle and on fifth, sixth and 

 seventh are two hairs in this position, one directly above the other 

 and close to each other and to the spiracle. No other hairs are found 

 (except on tenth abdominal). The spines get larger on the later 

 segments, but are much the same on 7, 8 and 9. On 9 there are 

 about eleven spines on either side, with a dorsal vacancy of the 

 width of three or four spines. On the fifth segment the front row 

 has eighty-two spines. The larger posterior ones are wider and 

 stronger than those in front, but not much longer, the longest about
