spines. The epimernm of the metathorax bears a snbbasal series of three or four 

 bristles and a snbapical series of three, the uppermost of these three standing close to 

 the stigma. The metanotnm bears three rows of bristles, besides a few additional 

 dorsal hairs. 



Abdomen. — The abdominal tergites 1 to 7 bear each two rows of bristles, and 

 tergites ] to bear each a slender bristle-like apical spine on each side. These spines 

 are much longer than in T. ddsi/cnemus. In the S there is on tergites 2 and 7 

 one bristle below the stigma, while on tergites 3, 4, 5, and 0, there are two below 

 it. In the ¥ there is one bristle below the stigma on tergites 2 and 6, two bristles 

 on tergites 3, 4, and 5, and none on 7. The seventh tergite bears two long 

 stont apical bristles, of which the lower one is about three-quarters the length of 

 the other, and a very minute hair above them representing a third bristle. The 

 sternite of the second abdominal segment of the S bears on each side one bristle, 

 and of the third segment two bristles, while the sternites of segments 4 to 7 bear 

 a patch of three long and four short bristles. In the ? there are similar patches 

 on sternites 3 to 7, the hairs being rather more nnmerous than in the S ; the 

 sternite of the second segment bears, besides a ventral bristle, several small 

 lateral ones. 



Legs. — The bristles of the forecoxa are more numerous and the rows rather 

 more regular than in T.dasijcnenitts. At the hinder edge of the mid- and hindcoxae 

 there are three bristles, two being long and one short. On the mid- and hindfemora 

 there is a ventral basal pair of hairs near the apex of the mid- and hindfemora, 

 and none on the lateral surfaces. The mid- and hindtibiae resemble those of 

 T. dasycnetnus. They bear a row of hairs near the dorsal paired bristles, another 

 row near the middle of the lateral surface, and a number of small hairs at and 

 near the ventral edge. There are seven dorsal pairs of bristles on the hindtibia ; 

 the first pair is small, the second, fourth, fifth, and seventh are long, while one 

 of the bristles of the third and sixth pairs is either reduced to a minute hair 

 or absent. The longest dorsal apical bristle of the hindtibia is about two-thirds the 

 length of the first hindtarsal segment. The first segment of the foretarsus is 

 nearly as long as the foretibia is broad, being about three times as long as broad. 

 The first segment of the midtarsns is longer than the second, being as long as 

 the longest apical bristle of the midtibia. The first segment of the hindtarsus is 

 three-quarters the length of the tibia. It bears eight pairs of hairs on the anterior 

 edge and seven on the hinder edge. The second segment bears six and five pairs 

 on their respective edges. The fourth segment is two-thirds the length of the 

 third ; the fifth (exclusive of claw) is a very little shorter than the third. 



Modified Segments. — The sexual apparatus is very diflerent from that of 

 T. dasycnemus. The plate of the penis is very broad, being irregularly ovate. 

 The clasper is large and conical (PI. XV. fig. 82, CI.), bearing two long bristles 

 at the apex and a few short ones. The movable finger (k) is very large. It 

 bears one moderately long bristle near the apex, accompanied by a few short ones ; 

 there are, besides, two extremely small spines at the apex and a number of 

 small hairs along the dorsal edge. The ninth sternite is long and slender 

 (PI. XIV. fig. 72), bearing some hairs at the apex. 



The eighth tergite of the ? (PI. XV. fig. 80) bears one hair above the stigma, 

 a long one below the stigma, and a number of hairs on the ventral third, as shown 

 in the figure. The apical margin is rounded below the middle and then sinuate. 



Length : S, 2-4 mm. ; ¥, 3 mm.
