rounded by groups of setae. The legs are about as long as the body is 

 wide and the tibia is very densely setaceous. 



The first abdominal segment is shorter than the metathorax and its 

 tergum bears four senti arranged in a transverse row; the dorsal pinacula 

 are yellow and the dorso-lateral ones are white; the lateral aspect is rect- 

 angular with a large lateral sentus the pinaculum of which covers the 

 greater part of the lateral surface and the paralaterals are wanting. The 

 sternum is about as long as the tergum, the ventral setae are adjacent on 

 the ventro-meson while the ventrolaterals are wanting. Abdominal seg- 

 ments two to five are similar, narrower than the first; their terga are sub- 

 equal in length, the dorsal and dorso-lateral senti of each segment are 

 arranged in a transverse row, and each sentus is provided with a distinct 

 pinaculum. The lateral aspect is nearly square; the lateral senti are 

 larger than the dorso-lateral, their pinacula are small. Ventrad of the 

 second and third lateral senti, there is a small paralateral seta and ventrad 

 of the fourth and fifth lateral senti, there is a paraleteral group of setae sur- 

 rounding a distinct paralateral chalaza on each segment. The sterna are 

 as long as their respective terga, slightly chitinized, their coriae are dis- 

 tinct, and each bears four chalazae arranged in a transverse row, each 

 chalaza surrounded by six or eight small setae. Segments six, seven, and 

 eight are each narrower than the preceding ones. Their dorsal pinacula 

 are fused and the dorso-lateral senti are shorter than the dorso-lateral senti 

 of segments two to five. Their lateral aspects are smaller, but are similar 

 in shape to those of the preceding segments, the lateral aspects of the 

 sixth and seventh segments are provided with small lateral senti, while the 

 lateral sentus of the eighth segment is much reduced and the pinaculum 

 is absent. Ventrad of each lateral sentus, there is a paralateral chalaza 

 surrounded by a group of setae. The sterna are as wide as the terga, their 

 coriae are distinct, and the ventral and ventro-lateral groups of setae sur- 

 rounding the chalazae are present. The ninth abdominal segment is 

 about as wide and about as long as the eighth, cylindrical, and inclined 

 ventrad. Its tergum is shield-shaped and has two distinct dorsal verrucae 

 near the caudo-mesal margin, the dorso-lateral verrucae are wanting. Its 

 lateral aspect is small, each with a distinct lateral verruca, ventrad of the 

 verruca there is a distinct paralateral chalaza surrounded by a group of 

 setae. Its sternum is short, deeply emarginated on the caudal margin, 

 the ventral and ventro-lateral groups of chalazae are present, and the 

 ventral chalazae are surrounded by a few setae while the ventrolaterals 

 are represented by a single chalaza. The tenth segment is small, not 

 visible from the dorsal aspect and the rectum is evaginated to form a disk- 

 like sucker. There is a pair of repugnatorial pores located in the coriae of 

 segments one to seven about one-half the distance between the dorsal and 

 dorso-lateral senti.
