154 THE entomologist's record. 



There is a similar thick short process on the second joint like a small 

 duplicate of the third one. There are five large convex eye-cornese in 

 a semicircle, and another (making six) near its centre. The labrum 

 has the usual kidney-shape (the median notch as the hilum). The 

 prothorax carries a plate, about 0-17mm. long and 0*4mni. broad, oval, 

 but that the posterior margin is nearly straight across ; if each half 

 were divided into three equal pieces by two lines, the four hairs on each 

 half would be one towards each end of these lines; the}" are very short, 

 about 0-025mm., and slightly thickened in the middle. The plate 

 itself is marked by a few lines of raised netvv^ork. Just beyond the end 

 of the plate, almost attached to it, is a very small dark plate with two 

 minute hairs. The spiracle is just below and some way behind this, 

 there is a solitary longer hair (0-05mm.) some way in front of the 

 spiracle, and a pair below near the leg. The leg itself has a hair or 

 two on its basal plate ; the three joints and claws are together about 

 0-25mm. long. The spiracle itself has a raised convex base with a 

 raised narrow crenate border round the opening. The mesothorax has 

 six (three on each side) very short (about 0-03mm.) hairs, about equally 

 spaced across the dorsum, and just beyond and in front of, and close 

 to, the outer, so close that they form an obvious pair, is a compara- 

 tively long (0"13mm.) slender hair; below that a single hair at about 

 the spiracular level, another lower and further back, in line with the 

 two at base of legs (on prothorax) ; the nietathorax is the same as the 

 mesothorax. The 1st abdominal segment has tubercles i well apart, 

 tubercles ii further apart and well back, and iii well down towards 

 spiracle; they are all well apart, and divide the area with fair equality. 

 The spiracle is smaller, but of the same structure as in the prothorax. 

 Just below it are two hairs on a level a good way apart, the front one 

 more in front than the posterior is behind the spiracle ; below these a 

 solitary hair (vi), well back, and another nearly ventral. The 2nd 

 abdominal segment differs from the 1st in ii being very near the 

 posterior border of the segment, and being nearer the middle line, very

little further out than i, whilst iii is notably further out ; iv and v are 

 further back, the spiracle is above a point midway between them, 

 instead of being much nearer the posterior tubercle. Below are 

 tubercles vi, vii, and viii (if the lowest is viii) in a line across segment, 

 about equally apart, vi the largest. On the 3rd, 4th, and 5th abdo- 

 minal segments, vi is further back, and has another hair behind it, and 

 there is below only vii (or viii) ; on the 6th iv and v are, one below 

 spiracle and the other behind and at a level midway between the first 

 and the spiracle, and vi and vii are represented by minute hairs 

 most difficult to see. The prolegs of this segment have the appeai-ance 

 of being attached to its posterior border. There is a plate with two 

 hairs, ventral to this a rather large hair with large base, and then the
