the tergites but the first and the eleventh longitudinally divided. The tergites have 

 the sclerites smooth or indistinctly shagreened, and have along their hindmost margin 

 about 18 moderately long hairs in addition to a median and generally two lateral hairs 

 in front of the row on each side ; the number and arrangement of " tactile " hairs are 

 probably as in Ch. similis Balz. 



Antennce (text-fig. 72, p. 290). — The galea, which extends very much beyond the 

 terminal hair, is very powerful and has numerous branches ; it is very variable, as 

 seen by comparing text-fig. 72 with Balzan's fig. 4 a (pi. 9). 



Palps (PL XXXI. fig. 32 «; text-figs. 78-79).— The palps are polished and almost 

 smooth, except the shagreened dorsal tubercle of the trochanter and minutely granular 

 surface of the femur and tibia ; the hairs are moderately long or long. 

 The troc/ianter, M'lilch is 1-5 as long as wide, is anteriorly very slightly 

 convex and posteriorly produced into a basal rounded and fairly 

 prominent tubercle ; dorsally it is prolonged into a deep protuberance 

 of a characteristic shape, having on the whole a somewhat triangular 

 appearance, with the obtusely-pointed tip directed somewhat towards 

 the extremity ; the outline is obtusely-pointed proximally and almost 

 semicircular distally with the tip well-defined from the lower part; 

 the trochanter is much deeper than wide, almost as deep as long, and 

 deeper than the femur. The femur has a rather short and well- 

 marked stalk, beyond vdiich it is only slightly attenuated towards the 

 extremity. It is 2'2 as long as wide ; anteriorly it is slightly convex 

 and then concave, while the posterior outline beyond the stalk is 

 abruptly convex and then almost straight ; the dorsal outline beyond 

 the stalk is abruptly convex and then moderately so, most raised 

 beyond the middle, passing into the rather sudden terminal concavity ; 

 the femur is a little deeper than wide. The tibia, which has a long 

 fairly well-defined stalk, is somewhat longer and wider than the 

 femur, and is almost 2*2 as long as wide ; the anterior outline is first moderately 

 convex and then terminally a trifle concave, while the posterior, beyond the fairly well- 

 marked condylus and elongated, but ill-defined, basal elevation, is very slightly concave 

 and then terminally moderately convex ; the ventral outline is moderately convex, 

 while the dorsal is slightly produced ; and the antero-dorsal surface forms a somewhat 

 conical, rounded, and very prominent tubercle. The chela, which is almost three times 

 as long as wide, is scarcely 1:2 as broad as the trochanter is long ; the hand, which is 

 about as long as the tibia, but 1-3 as wide, is 1'7 as long as wide, but only 1'3 as long 

 as deep, is 1"3 deeper than wide, and about 1*3 as long as the fingers, which are 1-3 as 

 long as the hand is wide, but only a trifle (1-05) as long as hand is deep, and which 

 gape considerably when closed ; the lateral outlines of the hand are only slightly 

 convex and so is the ventral, while the dorsal one is almost semicircular. The
