Legs. — The legs are perhaps even longer, with the tarsus of the first pair 4-7 

 as long as deep, and the femur of the fourth pair scarcely half as deep as the tarsus 

 is long. 



Measurements. — Cephalothorax 0*966 (0-805) ; abdomen 2-645 (1-265) mm. 



Palps: trochanter 0-460 (0-310) ; femur 0-805 (0-335); tibia 0-828 (0-368); hand 

 0-920 (0-515), depth 0-506 ; finger 0-667 mm. 



Leg I.: femur 0-570 (0-190), trochantin 0-091 (0-205); tibia 0-464 (0-114); tarsus 

 0-418 (0-089) mm. 



Leg IV.: femur 0-715 (0-247) ; tibia 0-705 (0-144); tarsus 0-502 (0-110) mm. 



Abnormality. — The hindmost segments of the described male show dorsally an 

 abnormal structure, similar to that which I have described in Ch. javanus Thor. 

 (31. p. 137, pi. viii. fig. la), though of a less complicated structure. The left 

 exterior fourth of the tenth and the eleventh tergites are laterally completely fused 

 without a trace of limitation between ; the two tergites are consequently only 

 distinguished from each other in the right three-fourths ; the arrangement of the hairs 

 on the left is somewhat irregular, and the longitudinal line of the tenth tergite is 

 directed obliquely backwards towards the left. 



Material. — Of this species Dr. Meinert sifted six specimens (2 d and 4 ? , one with a 

 bundle of eggs) in the month of August at La Moka, and a single female (without 

 date) as well as a single male at Caracas in the month of July. Balzan's specimens 

 are from the Amazons. 



Remarks. — The identification of this species with Balzan's species I regard as certain, 

 in spite of its larger size and slightly different proportions of the joints of the palps. 

 From Ch. nitidus Ell. it difi'ers by larger size, shorter fingers, and bigibbose trochanter ; 

 as regards the difierences from Ch. argentinus I refer to that species.

Male. 

 Cephalothorax. — Large ocular spots fairly distinct. The cephalothorax, Avhich is 

 distinctly longer than wide, has the anterior transverse stripe fairly distinct and 

 slightly curved backwards in the middle, while the almost obsolete or rather indistinct
