sixth tlie length o£ the segment ; tarsus about twice as long 

 as tibia. . , 



Legs with femora finely spicular ; coxte granular, witlx 

 marginal tridenticulate, columnar tubercles. Genital plate 

 granular. 



Abdominal sterna sparsely granular. 



Total length about 3 millim. ; femur of first leg o, of 

 second 8 (entire appendage about 34), of third 4*5, of fourth 7, 



Loc. Venezuela: Merida. 



Specimens from the same locality which I regard as the 

 females of the above-described males are larger, reaching 

 6-5 millim. in length, and have a pale median, sometimes 

 t-shaped dorsal band, and the legs more annulate. 



Prionostemma scintillans, sp. n. 



5 ,^ Colour. Trunk a tolerably uniform blackish or dark 

 brown, with a metallic golden marginal patch on each side of 

 the fore part of the carapace, a similar one on the outer side 

 of the distal portion of the coxa of the fourth leg, and two on 

 the second free tergite of the abdomen; ventral surface, 

 mandibles, palpi, and legs yellowish, with the exception of the 

 trochanter and extreme base of femur, which are blackish. 



Structurally closely allied to the preceding species; the 

 dorsal surface similarly sculptured; but the ocular tubercle, 

 which is rather lower, is nearly smooth above and furnished 

 only with a small and inconstant number of irregularly 

 disposed denticles, a single anterior pair being the only ones 

 of invariable occurrence. 



Length 4-5 millim. 



^. — Resembling female in colour and other characters, 

 but smaller. 



Total length barely 4 millim.; femur of first leg 11, ot 

 second 16 (length of entire appendage about 55), of third 11, 



of fourth 13. 1 • //I c 7A

Prionostemma hicolor, sp. n. 

 ^ 5 .—Very nearly allied to P. scintillans, but differing

 suffusion of gold ; mandibles and palpi yellowish brown ; 

 genital plate and the abdominal sterna much paler yellow ; 

 cox« and trochanters of the legs deep brownish black and 

 contrasting with the paler dorsal and ventral areas ;_ the mem- 

 brane between the trochanter and coxa greyish white.
