NOTES ON THE CAPTURE OF CLAVIGER LONGICORNIS MULL. 293 



lengths of the segments being as 1, 3, 4, 2|. The first and second are 

 simple, the second a little swollen terminally, the third is angular 

 and elaborate, a projection of the inner margin carries a strong hair. 

 The extremity of the inner margin slopes outwards and carries 

 several short hairs and a curious curved joint, the fourth joint carries 

 four terminal hairs, three larger than the other, and each on a 

 rounded projection, giving a trefoil clubbing to the end of the joint 

 (fig. 5). The labrum 0-27mm. across and 0-lmm. deep is nearly 

 rectangular, the margin being slightly curved. The margin is crenate, 

 the two central crenations having a straight margin, the next two 

 on each side are rounded and each carries a short pointed baton 

 and a hair behind its inner margin, there are several other short 

 hairs (fig. 8). What appears to be the maxilla, but of which much 

 can only be seen by the transparency of the parts, is O-ilmm. long, 

 has a first and second strong broad joint, from the end of the second 

 proceeds, 1st, a two jointed process, the last joint carrying a minute 

 palpus and a hair; 2nd, a single jointed process with a fringe of short 

 hairs at its extremity (fig. 4). The labium is a square plate, produced, 

 however, in front, about 0-06mm. wide and O'OSmm. long, at the 

 anterior corners on either side is a three-jointed palpus, the second 

 joint short, the third minute. At the base of each palpus is a fan of 

 minute hairs, and the extremity in front is a feather-like process, with 

 very numerous down-lil<e hairs (fig. 6). Immediately behind the 

 labium is a dark transverse line of finely fringed chitin, behind this a 

 simple line, bounding a somewhat triangular, more transparent area 

 (fig. 6). 



The prothorax carries sundry hairs (fig. 1), and a spiracle on either 

 side just below its posterior margin (fig. 7). The spiracle presents a series 

 of nearly concentric circles and is about 0'06mm. across, the legs of 

 this and the two succeeding segments arise towards the posterior 

 margin of the segment. The legs are somewhat shrunk (in places) 

 and distorted, but they consist of a basal portion (coxa) which is about 

 0-4mm. long, rather curved, and in life is probably directed down- 

 wards, the trochanter is not distinguished, the femur and tibia are 

 about the same length as the coxa, and have numerous hairs. There 

 is a terminal spine (a stronger hair) to the tibia, and a short, curved 

 sharp claw 007mm. long (fig. lO). The abdominal segments have 

 each a long hair on each side of the dorsum and two at either margin 

 and a spiracle that projects in a somewhat bulbous form in the 

 specimen (fig. 9). 



The eighth (and last with spiracle) abdominal segment carries on 

 each side a long (0'64mm.) dorsal process (cercus ?) apparently three- 

 jointed, with sundry very long hairs, the terminal one 0-45mm. long 

 (fig. 11), ventrally each side has also a much simpler process (figs. 11 

 and 12). The ninth abdominal segment, as seen from above, is a 

 slight, nearly square plate (fig. 1), with a pair of longer and a pair of 

 shorter hairs. Probably this is really the tenth, the ninth being 

 obscured by shrinkage.
