 II, No. 2, p. 94). The cephalothorax, however, falls more or less 

 steeplj' from the dorsal eyes, even in H. regia, which is the 

 flattest of the three species here described. Heradea, too, lacks 

 the low long flat look of Epinga, the abdomens, although 

 rather slender, not being so long, narrow and cylindrical as in 

 that genus.

 Smaller specimens have a length of 7.5 for the male,

The colors are red,^ white and black. 



The cephalothorax is moderately high. It slopes upward 

 to the third row of eyes and then, in the female, falls very 

 gradually through half of the thoracic part, the final fall being 

 a little steeper. In the male the nearly level part just behind 

 the dorsal eyes is shorter. The quadrangle of the eyes occu- 

 pies two-fifths of the cephalothorax. The second row is half- 

 way between the first and the third. The clypeus is about 

 one-third as high as the large middle eyes. The falces are 

 long, stout and vertical, with a relatively small fang. 



The coloration is extremely striking. The cephalothorax 

 of the male is jet black with wide bands on the sides, a central 

 band on the thoracic part, and a large patch just over the first 

 row of eyes, all of snowy white. The palpus carries out the 

 same plan, the femur and patella being covered with snowy 

 white hairs, and the tibia and tarsus with black hairs. The 

 abdomen is of a very vivid red, nearly encircled by a white
