The prostenmm is narrower than in Poltjctenes molossus, the sides being 

 strongly shxnting and the iutercoxal process long, strongly cbitinised, pointed, and 

 slender. The meso- and metasterna are nearly the same shape as in PI. Xlll. 

 fig. 0, but the mesosternum is rather longer. The nietasteruite has a peculiar 

 c'haracter not found in other species, the pleura being produced laterad into a 

 ])yramidal process which extends above tbe hind edge of the mid coxa. 



The proximal abdominal tergites bear one regular row of bristles at some 

 distance from the apical margin, the row becoming irregular and doubled or trebled 

 at the sides ; the fourth and following segments also have centrally but one row 

 in the (J, the row being irregularly doubled iu the ?, which sex has also more 

 numerous bristles laterally than tlie S ; the segments v, vi, and vii in the ? and 

 vi and vii in the S have an apical row of long bristles, by which this species is 

 easily distinguished from the next. The apex of the fore tarsus is characteristic, 

 bearing five long bristles at the tip. The two central ones of them are evenly 

 carved, being nearly of equal length and slightly widened at their tip. Above 

 them is a long bristle and below them a shorter one, and towards the outer side 

 is placed the pair of claws, the longer claw being longer than any of the 

 bristles, curved and then recurved, and terminating in a long thin point. The 

 smaller claw of the other tarsi is slenderer than in Poh/cfencs molossus. 



The fore tibia of our i is so placed that the brush of hairs at its ajiex can 

 distinctly be recognised as being a membranous flap which bears hairs on the under 

 surface only, i.e. on the side away from the tarsus. 



Immature specimens. — Waterhouse's figures, I.e., are very characteristic outline 

 drawings of the head, thorax, and base of the abdomen, the armature of the first 

 antennal segment also being correctly represented, as far as correctness can be 

 expected from a representation on a small scale. But as hardly any further details 

 are given in the original descrijition, we have taken some supplementary notes 

 from the type of spasmae and the cotype. The first antennal segment bears on the 

 upper side a subapical row of five short bristles, of which the three outer ones are 

 thin and the two lower ones thick. The npper surfaces of the second and third 

 segments bear numerous bristles, two on the second and one on the third being 

 long. On the under side the bristles are fewer iu number. The second segment 

 has here two longitudinal rows of four or five, those of the inner row being the 

 thicker, there being also four or five small apical bristles. On the third segment 

 tbe inner row is represented by three bristles and the outer by one. 



The proboscis, clipcus, and the apex of the fore tarsus are almost exactly as in 

 the adult. 



The gular comb contains eighteen spines in each half, and does not nearly 

 rrach to the l.)asal angles of the head. There is one small bristle behind the comb, 

 another on a level with the last-but-one spine, a larger one before the basal 

 angh', and a small one at the tip of the angle. In front of the comb, between 

 it and the first segment of the antenna, there is one bristle. There are six small 

 but rather stout bristles before the central portion of the hind xuargin, and one 

 on each side a short distance forward. At the sides of the central channel we 

 find only one exceedingly small liair. 



The pronotum is broader than long (6 : o) and widest before the centre. The 

 greater proportion of the surfa.ce is bare of bristles, which are almost confined to 

 the lateral area, base, and apical margin. 



The elytra are small, and do not cover the metanutum. They bear bristles
