which is partly covered by the coxae of the fourth pair and curved backwards 

 in the middle. 



Antennae (PI. IV, fig. 12 b-c). — The flageUiim consists of two hairs, of which 

 the broader and longer anterior one possesses three median marginal teeth, while 

 the posterior has only a single one (fig. 12 b,/'); the lamina interior has beyond the 

 well developed plate-shaped portion three dentated lobes and a rather short serrated 

 spine; the serrula exterior consists of about 14 rather long squarely-truncate teeth 

 in addition to two longer, a basal one, which is widened out towards end, and a 

 terminal pointed one, which is partly free (fig. 12 c). The galea {g), which has a 

 most remarkable form, consists of two divisions, which do not even at their base 

 seem to be fused; they diverg and both extend a trifle beyond the terminal hair; 

 the superio-interior division is cylindric and tapering towards its summit, where it 

 is divided into two hair-like, obtusely pointed branches, about one third of the 

 basal part in length ; the inferio-interior division is thicker, and near to the base 

 provided with a rather thick branch, while it terminally is divided into three very 

 slender obtusely-pointed branches, a single more dorsal, arising between the bases 

 of the two others more ventral (fig. 12 c, g). 



Maxillae (PI. IV, fig. 12d). — The maxillae are most raised in the middle, 

 falling gradually towards the apex, but rather steeply backwards and laterally; the 

 anterio-exterior corner is rounded and by a distinct notch separated from the 

 rather short manducatory part, which is surrounded by a suddenly pointed rather 

 narrow lamina maxillaris {Is}, rounded interiorly, but almost straight exteriorly, 

 with a few marginal teeth. The maxillae are everywhere provided with big, pointed 

 granules and distinctly clavate hairs except the manducatory part, which is almost 

 smooth with a few pointed hairs (fig. 12 d). 



Palps (PI. IV, fig. 12 a). — The palps, which are almost as long as the body, 

 are distinctly granular with more or less rounded scale-shaped granules, which are 

 slightly developed on the stalks of the ditTerent joints and completely wanting on 

 the fingers. The palps are provided with hairs, which are either distinctly clavate 

 or widened out terminally, or with a number of marginal teeth; those of the hand 

 are more simple, and the fingers have in addition to the usual, almost or com- 

 pletely simple hairs a number of tactile hairs. The immovable finger bears ante- 

 riorly two basal tactile hairs, the one more ventral and the other placed a little 

 more distal near to dorsal margin, as well as a single one just beyond the middle 

 in a dorsal position in addition to three sense-spots; posteriori}' it is provided with 

 two basal tactile hairs, one median and one terminal. The movable finger has 

 anteriorly a single basal sense-spot and posteriorly one (two?) basal and three 

 median tactile hairs in addition to a few spots. The trochanter, which has a long 

 and well defined stalk widened out towards the base, is 15 longer than broad; 

 the anterior margin is beyond the rather deep notch of the stalk distinctly convex; 

 the posterior margin is produced into a long, fairly slender and rounded process, 

 which is almost perpendicular on the stalk, but gradually slopes towards the
