No. 1 .] A NT-LIKE SPIDERS OF THE FA MIL Y A TTIDJ'l. 25 



Ceplialothorax moderately high, with a marked constriction 

 behind dorsal ej'es. Cephalic part a little higher than thoracic. 

 Quadrangle of ej^es one-quarter wider than long, a little wider 

 behind than in front, occupying a little more than one-third of 

 cephalothorax. Anterior eyes in a row which is somewhat 

 curved downward, subtouching ; middle a little more than twice 

 as large as lateral eyes. Clypeus one-fifth as high as middle 

 eyes. Second row .plainly nearer first than third row. Falces 

 in one variety long, slender and rounded, in the other shorter 

 and wider and more triangular in transverse section ; in both 

 varieties they are horizontal and i^arallel. Lip longer than 

 wide. Coxfe i separated by less than width of lip. Sternum 

 long, very narrow, contracted at both ends. Pedicle long. 

 Abdomen cylindrical, with constriction in anterior third. 

 Tibia of palpus nearly as long as tarsus. 



We have a long and a short variety of this species ; in the 

 short, the fang of the falx is nearlj' straight; in the long it has 

 a bend at the insertion and a curve in the middle ; the teeth, 

 also, are different. The difference shown in the drawing between 

 the abdomens of the two varieties is probablj^ caused by a con- 

 traction of the smaller one in alcohol. 



Color. Cephalothorax black, with a white band at the con- 

 striction and some white hairs around the eyes. Abdomen 

 glossy black, especially the posterior portion, with a white band 

 at the constriction. Legs light brown, excepting the femoral 

 joints, which are dark. Falces, palpi and under surface, dark 

 brown. 



Habitat. ■ Madagascar. 



We have three males of this genus from Madagascar — 

 simplex, augustus and electricus. Of these, simplex is' much 

 the largest and heaviest. Augustus has the tibia of the palpus 

 nearly as long as the tarsus, while the other two species have it 

 only about one-third as long.
