11 broader than tibia and about 15 longer than (ingerx. "Tactile" hair of the fou rtli 

 tarsus is median; the tarsus of the first pair of legs is a little shorter than the tibia 

 and 5 times longer than deep; the claws are simple: the articulation between the 

 trochantin and femur I slightly developed. 



Ç. Céphalothorax. — Two rather distinct ocular spots present, a little 

 removed from front margin. The céphalothorax is a little longer than broad; it 

 has a rather peculiar shape, as its lateral outlines are distinctly convex in the 

 middle and behind moderately concave. Two transverse stripes, of which especially 

 the posterior is rather indistinct, are present; the anterior appears as though it 

 were curved backwards, but it is really straight in the middle and has the anterior 

 limitation, which is directed outwards and curved backwards as usual, more pro- 

 nounced than the posterior. The integument is everywhere provided with minute 

 granules, more pointed in front and more rounded behind, as well as with mode- 

 rately long and distinctly clavate hairs. 



Abdomen (PI. Ill, figs. 8 a). — The abdomen is moderately long and slender, 

 and all its tergites with the exception of the last ones are longitudinally divided 

 by a very indistinct line; the three first tergites are only a little shorter than the 

 following. The integument of the tergites is printed all over with short transverse 

 raised ridges, which are curved backwards in the middle, the whole resembling 

 scale-shaped granules; distinctly clavate hairs are abundant, which are in the first 

 tergites about 4 times as long as broad terminally, but in the last about 9 (fig. 8 a). 

 The three first tergites with 12 hairs along the hindmost margin, and the following 

 seven bear in addition lo these on each side a lateral and a median hair, like the 

 others placed in a white smooth spot; the hairs of the marginal row of the ninth 

 and tenth tergites are placed irregularly, sometimes in front of the row and some- 

 times in different numbers in each half. The eleventh tergite bears in addition 

 to the usual hairs, which are placed without proper order, at least one pair of 

 "tactile" hairs, and so does the eleventh sternite. The sternites are almost smooth 

 and bear along the hindmost margin about 16 marginal, very long and slender 

 hairs, which are completely simple in at least the first 8 segments; the eight and 

 the ninth sternites bear on each side in the middle a short spine like those of 

 the male. 



Antennae (PI. Ill, figs. 8 c-d). — The flagellum consists of four hairs, of which 

 the anterior has marginal branches (fig. 8 c). The lamina interior with three den- 

 tated lobes and a long and slender spine; the serrula exterior consists of about 20 

 teeth, of which the basal is not very much widened out towards the end. The 

 galea is fairly long and slender, extends a little beyond terminal hair and bears 

 () distal, rather short teeth (fig. 8 d). 



Maxillae (PI. Ill, fig. 8 f). — The maxillae are only granular laterally; their 

 manducatory part {ma) is rather short and with the inner margin moderately con- 

 cave and surrounded by a long and broad lamina maxillaris (As) which has liie 

 exterior marain dentated and Ihe inlerioi- a concave one without teeth.
