Abdomen (PI. Ill, fig. 1 a). — The abdomen is elongate-oval and distinctly 

 longer than broad; the third lergite is about 6 times as broad as long; all the 

 tergites, with the exception of the eleventh and to some extent the first, are indistinctly 

 longitudinally divided. The hairs are almost simple with a single or a few terminal 

 teeth (fig. 1 a); those of the first tergites are moderately long and slender, while those 

 of the eleventh f. inst. are very much so; the hairs are placed in a transverse row 

 along or near to hinder margin of the sclerites to a number of about 12; the ter- 

 gites beyond the second bear on each side a single hair laterally in front of the 

 row. The eleventh tergite as well as the sternite bear a pair of long slender 

 ''tactile" hairs. 



Antennae (PI. Ill, figs. 1 b-c). — The flagellum consists of three hairs, of which 

 the anterior bears a few tiny teeth near tip; the lamina interior has four dentaled 

 lobes; the serrula e.iiterior consists of 17 teeth, of which the basal is the longer, 

 and, where it is enlarged terminally, it bears a rounded flap; its terminal tooth 

 is not pointed. The galea extends distinctly beyond the terminal hairs and is 

 mounted with about seven distal short branches (fig. 1 b). 



Palps (cf. PI. Ill, fig. Id). — The palps appear smooth, but not polished and 

 are provided with hairs, which are broken and mounted with a single or a few 

 distal teeth on all joints except the fingers; those of the trochanter and femur are 

 a little obtuse in contrast to the pointed ones of the tibia and the hand. The 

 fingers bear a number of tactile hairs as well as sense-spots: the immovable one 

 bears posteriorly and dorsally two basal and two distal tactile hairs in addition to 

 six spots, while it anteriorly has three(?); the movable one bears four tactile hairs 

 and four spots. The trochanter, which has a distinct stalk, is 18 times longer than 

 broad and perhaps a little narrower than femur; the anterior margin is beyond 

 stalk evenly convex and the posterior very slightly so; the dorsal surface is slightly 

 produced posteriorly, but we can not in a proper sense speak about a dorsal 

 posterior tubercle. The femur, which has a moderately long and well marked 

 stalk, is three times as long as broad, as long as but distinctly narrower than the 

 tibia, and gradually widened out towards the tip; the anterior side has beyond 

 the notch a scarcely marked convexity extending to near the tip, where a short 

 distinct concavity is found ; the posterior is distinctly convex just beyond the stalk, 

 then almost straight and towards the tip convex again. The tibia, which is about 

 4 times longer than the short and distinct stalk, is 2'6 longer than broad and 12 

 broader than the femur; the anterior outline is moderately convex beyond the 

 rather shallow notch of the stalk; the posterior surface has a rather prominent 

 condylus, followed by a low concavity and the basal elevation, which is fairly well 

 defined proximally, but distally merges into the almost straight outline of the joint 

 projjcr: this is towards the tip distinctly convex. The hand is a trifle shorter than 

 the tibia and 14 broader; it is almost as broad as the trochanter is long, 18 times 

 longer than broad, as broad as it is deep, and 14 longer than the finger; both 

 lateral outlines are moderately convex, most suddenly the posterior.
