26 PECKUAM: [Vol. 2, 



Cephalothorax: Length, 2.6 mm.; width, 1.4 mm. 

 Legs, 4132; femur of first enlarged, 4 and 1 nearly 



equal. 

 Tibia i with five pairs, and metatarsus i with two 

 pairs of long slender spines. 



Cephalothorax moderately high, with a very slight con- 

 striction. Cephalic part a little higher than thoracic. Quad- 

 rangle of eyes very little wider than long, a little wider behind 

 than in front, occupying about two-fifths of cephalothorax. 

 Anterior eyes in a straight row, subtouching; middle barely 

 twice as large as lateral. Second row nearer first than third 

 row. Clypeus only a line. Falces horizontal, robust and flat- 

 tened above; the outer edges have, about in the middle, a notch 

 and a slight projection; looked at from the side they are slightly 

 thickened near the proximal end. Lip a little longer than 

 w'ide. Coxse i separated by width of lip. Sternum long, oval. 

 Pedicle not visible from above. Abdomen cylindrical, with a 

 constriction in front of middle. Tibia of palpus but little more 

 than one-third as long as tarsus. 



Color. Cephalothorax dark reddish-brown, excepting the 

 interocular area, which is yelloM'. Abdomen, in front of the 

 constriction, dark brown; behind it, pale yellowish, with a brown 

 spot above. There are two dark rings around the abdo- 

 men, one in front of, and one behind, the constriction. Legs, 

 falces, palpi and under surface medium brown. 



Habitat. Madagascar. 



The yellowish color of this species distinguishes it from 

 simplex and augustus, which are very dark brown or black. 

 It is, moreover, a much smaller, more delicate spider than 

 simplex. The tibia of the palpus in electricus is but little 

 more than one-third as long as tarsus, while in augustus it is 

 two-thirds as long.
