prndnced posleriorlij ; femur twice as Ion(j as broad, as long as and dislinctly narrower 

 than tibia, which has lateral outlines strongly convex with posterior basal élévation 

 slightly developed. The hand is much longer than the tibia and i 3 broader, 16 longer 

 than broad, but only 12 longer than deep, and l.'i longer than fingers, which are 

 provided with ctccessory teeth and anteriorly at the base of the immovable one with 

 13 densely placed sense-spots. ,, Tactile" hair of fourth pair of legs is wanting; tibia 

 of the first pair is a little longer than the tarsus, which is 3-'i longer than deep. 



c?. Céphalothorax. — Indistinct ocular spots present. Tlie cephalotliorax 

 is a little longer than broad with the marginal portion very long and provided 

 with a distinct membrane; an indistinct median transverse line is present, which 

 seems to be slightly curved backwards in the middle, and a second is indicated by 

 a row of muscular spots between the dark first thoracic tergite and the pale second. 

 The skin is finely reticulate, and the hairs are fairly long and slender, but obtuse. 



Abdomen. — The abdomen is more than twice as long as broad, of almost 

 equal breadth throughout, and consistently of a very slender appearance; the ter- 

 gites are not longitudinally divided, are of almost equal breadth, but increase in 

 length towards the tenth; on account of this structure, and because the articulate 

 membranes are long between the first tergites, but scarcely visible between the 

 last ones, the abdomen gets a distinctly darker appearance behind. The skin is 

 almost smooth and the long and slender hairs obtuse. The sternites are very 

 similar to the tergites and the genital area seems to be similar to that of Ch. cimi- 

 coides F. 



Antennae (fig. 2 a). — The flagellum has only three (?) hairs; the serrula e.vterior 

 consists of about 20 teeth, of which the basal one is the longer, almost pointed 

 and scarcely enlarged distally, as the anterior membrane is very narrow. The 

 galea is long with three pair of branches, of which the basal one is the longest, 

 and extends distinctly beyond the terminal hair (fig. 2 a). 



Maxillae. — The maxillae are almost smooth, and have their manducatory 

 part as well as the lamina maxillaris rather short and broad. 



Palps (figs. 2 b-c). — The palps, which are a little shorter than the body, 

 are smooth or almost so, and provided with a number of long, slender and slightly 

 obtuse or simple hairs in addition to the tactile hairs of the fingers. The immo- 

 vable linger bears anteriorly three basal tactile hairs, two proximal the one above 

 the other and a single one more distal, and in the area between these or a little 

 apart 115 bigger and smaller sense-spots close together; j)osteriorly it has three 

 proximal tactile hairs and two spots and distally a single tactile hair. The movable 

 finger bears anteriorly three big sense-spots in inner third (fig. 2 c), and posteriorly 

 four(?) tactile hairs in a longitudinal row and two sense-spots. The trochanter, 

 which has a moderately short and distinct stalk, is 1-4 longer than broad and 

 distinctly narrower than the trochanter; the anterior margin is beyond stalk very 

 moderately convex; the posterior has in the first place a rather abru]it curvature 

 to mark olT the stalk and is then almost straight; dorsal surface is not in the
