Remarks. — This species, which is easily recognized hj' its vevy slender 

 palps, especially the hand, with its short fingers, and short clumsy legs together 

 with its characteristical colour, ditTers from Ch. orites Thor. by its very slender 

 hand and from the species, which Ellingsen identified with this, by the long 

 tubercles of the trochanter and its more slender palps; from all other species of 

 the C/i. Birmanicus Thor. group except from Ch. Thorelli Balz., which has a trans- 

 verse stripe, by its short fingers.

 (PI. IV, fig. 9 a; fig. 22, p. 192). 



c?. Small distinct ocular spots; céphalothorax longer Hum broad without trans- 

 verse line, almost smooth with almost simple hairs. Fairly long and slender abdomen 

 with distinct tergal and sternal sclerites, with 6 hairs in front of marginal row in 

 median tergites and with terminal "tactile" hairs: genital area of ,, Birmanicus" Igpe. 

 The partly granular palps almost of equal length to body: trochanter distinctly longer 

 than broad with posterior margin almost triangularly produced and the dorsal surface 

 provided with a very high conical tubercle: the femur is 25 longer than broad, a 

 little shorter, but distinctly narrower than the tibia, which has cm e.vtremely long 

 stalk, distinctly convex lateral outlines and a long indistinctly marked basal elevation. 

 The hand is 11 broader than the tibia, 19 longer than broad, I'l longer than deep 

 and 1Ô longer than finger. ,, Tactile" hair of the fourth pair is placed at the base of 

 the tarsus; the tibia of the first pair is much longer than the tarsus, which is 43 

 longer than deep. 



Céphalothorax. — Distinct, but small ocular spots are found. The cephalo- 

 thoracic shield is distinctly longer than broad and almost as broad a little behind 

 the eyes as at the hindmost margin; no transverse lines are visible, but the "head" 

 is indistinctly marked off by being better raised and a little darker; the integu- 

 ment is almost smooth with the exception of that of the head, which appears 

 minutely granulated; the few hairs are short with a few teeth distally. 



Abdomen. — The abdomen, which is about twice as long as broad and of 

 a rather elongate appearance, has the tergal sclerites very distinct and in the single 

 s|)ecimen arranged in a rather curious way; the fourth to the eighth are placed 

 close together with scarcely marked articulate membranes, while the others are 

 separated from each other by membranes almost as long as the tergal sclerites 

 themselves; they are all, except three viz. the two (three) first and the eleventh, 

 divided by a well marked longitudinal line. The sclerites bear, with the exception 

 of the first three, six hairs in front of the marginal row, of which the four median 

 ones are placed within prominent white spots. The sternal sclerites are very 

 distinct and longitudinally divided with the exception of the eleventh; the eleventh 

 tergite as well as the tenth and eleventh sternites with ''tactile" hairs. The structure 

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



Antennae. — The flagellum consists of four hairs, of which the anterior has
