c?. Ce plia loi ho la X. — Indislincl ociihir spols present. Tlie céphalothorax 

 is disliiiclly longer Hum broad behind, where il is only a little broader than a utile 

 behind the ocular spots; no transverse lines, but the darker and better raised 

 "head" is nevertheless marked olT; the skin is smooth with rather short dislally 

 toothed hairs. 



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

 has the tergal sclerites indistinct, and the median ones are divided by an almost 

 obsolete longitudinal line; the hairs, which are moderately long and slender and 

 with a few distal teeth, are on the three fust lergites placed in a marginal row, 

 while the others have at least G(?) hairs, placed in front of the row; the two last 

 tergites as well as the sternites bear two pairs of "tactile" hairs. The structure of 

 the genital area is in the main similar to that of Ch. Birmanicus Thor. 



Antennae (PI. IV, fig. 11a). — The anterior hair of the four(?), of which the 

 flagellnm is composed, with about five marginal teeth; lamina interior with three 

 dentaled lobes and long serrated terminal spine. The galea, which has only a few 

 very tiny teeth distally, does not extend beyond the terminal hair (fig. 11a). 



Maxillae. — The maxillae arc smooth, and the rather narrow lamina maxil- 

 laris is serrated exteriorly. 



Palps (PI. IV, fig. 11 b; fig. 24, p. 197). — The palps, which are a little longer 

 than the body, are granular all over with minute, low and not very densely placed 

 granules with the exception of the ventral surfaces, the stalks, the anterior sur- 

 face of the trochanter and the fingers; the dorsal trochanteral 

 tubercle is near to its summit provided with a few pointed bigger 

 granules. The hairs are generally long and stiiT with a few teeth; 

 at least one longer and more slender and completely simple is 

 found posteriorly near to the middle of the femur; the tactile 

 hairs and the sense-spots of the fingers are arranged in the main 

 so. The immovable finger bears anteriorly two basal tactile hairs, 

 one median dorsal and one placed a little in front of and below 

 this, in addition to at least 7 sense-spots, arranged in a longitu- 

 dinal row between the three proximal hairs; posteriorly two 

 basal, one median and one almost terminal tactile hair in addition ^jg. 24. 



to 6 proximal sense-spots. The movable finger has at least three C/i. ;o<ii/it/iis ii.sp. ;

apart trom each other anteriorly, and posteriorly two basal sense- 

 spots at least, in addition to two basal and three (V) median tactile hairs. The trochanter. 

 which has a rather short but distinct stalk, is 1'6 longer than broad and much 

 narrower than the femur; its anterior surface is beyond the stalk moderately con- 

 vex; the posterior margin is beyond the stalk produced into a process, which is 

 well defined from the stalk, rather low and sloping gradually towards the tip; the 

 dorsal surface is produced into a high, conical, obtusely pointed tubercle, which is 

 directed upwards and backwards, being so high that the trochanter is distinctly
