distinctly granular on the head and first tergite, but less distinctly so on the second 

 tergite and is provided with short obtuse hairs. 



Abdomen. — ^The fairly long slender abdomen has apparently all tergites except the 

 first and eleventh longitudinally divided. The sclerites are indistinctly granular, and 

 about ten rather short and slightly clavate hairs are placed along the hinder margin 

 of each tergite in addition to two lateral ones in front of the row. No " tactile " hair 

 was observed in the eleventh segment in this badly preserved specimen. The sexual 

 area is very prominent, with the anterior genital plate, which has its prominent hinder 

 margin concave, longer than the posterior ; chitinous apparatus as well as the 

 accessory glands, visible through the transparent skin, very similar to those of 

 Ch. cimicoides F. 



Antennce. — The rather short galea scarcely extends beyond the terminal hair and 

 has about six short terminal branches. 



Palps (PL XXX. figs. 22 a-c). — The maxillce are smooth in the middle, but 

 granular laterally; the three proximal joints are distinctly granular on the anterior 

 surface, but more or less indistinctly so everywhere else ; the hand seems to be granular 

 only anteriorly and posteriorly, elsewhere being smooth. The fairly long or long 

 hairs are obtuse and dentated or even slightly clavate. The trochanter, which is 1-5 

 as long as wide, is anteriorly moderately convex and posteriorly as well as dorsally 

 slightly produced. The femur has a fairly short and well-defined stalk, beyond which 

 it is of almost equal breadth throughout, but for the slightly attenuated terminal part. 

 It is 2-4 as long as wide ; anteriorly it is slightly convex and then concave, but 

 posteriorly beyond the not very abrupt basal convexity almost straight and then 

 terminally slightly convex. The tibia, which has a moderately long and well-marked 

 stalk, is a little longer and wider than the femur, and 2"2 as long as wide ; the anterior 

 outline is moderately convex, while the posterior, beyond the slightly marked condylus 

 and obsolete basal elevation, is almost straight and then slightly convex. The chela, 

 which is three times as long as wide, is 1*2 broader than the trochanter is long; the 

 hand, which is about as long as, and 1*4 as wide as, the tibia, is 1-6 as long as wide, 

 a trifle wider than deep, and scarcely 1"2 as long as fingers, which are much longer 

 than the hand is wide and gape slightly when closed ; the lateral as Avell as the dorsal 

 outlines are moderately convex, while the ventral is very slightly so. Anteriorly both 

 fingers bear about six accessory teeth placed close together just beyond the middle, 

 while the movable finger has four posteriorly and the immovable three ; marginal row 

 of teeth complete in both fingers. Anteriorly eight si[)ots, placed in two groups 

 (fig. 22 V), are found on the immovable finger and only a single one basally on the 

 movable finger, while, posteriorly, the immovable finger is adorned with seven spots 

 and the movable with three only (fig. 22 c). 



Goxce. — The coxse are very similar to those of Gh. celerrimus, sp. n. [cf. below),
