red ground-color sometimes fades to nearly white in alcohol. 

 The i^alpi are pale yellowish, with light hairs. The legs are of 

 a lighter or darker reddish color, not -^'ery hair3^ but with some 

 pale golden scales. The color deepens, in most specimens, on 

 the femora, the distal halves of the tibia and the tarsi. The 

 falces are light or dark red, with white hairs along the inner 

 sides. The extremities and the fangs are blackish. 



We have four females from Chapoda, Brazil, in the Smith 

 Collection, and a fifth from Panama, in the Keyserling Collec- 

 tion. 



PARN^ENUS, GEN. NOV. 



Large, handsome spiders, with distinct markings. 



The cephalothorax is high and massive. When looked at 

 from in front, the sides are seen to bulge out on each side of 

 the first row of eyes. The anterior part of the cephalic plate is 

 inclined forward. The thoracic part falls from the dorsal eye 

 to the hinder margin, the slope being more abrupt after the 

 first half. The lower outline of the sides is not far from circu- 

 lar, but there is a distinct bulge just behind the first row of 

 eyes where the cephalothorax is widest. Thej^ round out wide- 

 ly from above downward, so that, although the dorsal eyes are 

 on the sides of the upper surface, they form a row which is 

 much narrower than the cephalothorax at that place. The 

 quadrangle of the eyes is very slightly wider behind than in 

 front. It is barely one-fourth wider than long, and occupies 

 nearly one-half of the cephalothorax. All the eyes are small in 

 proportion to the size of the spiders. The anterior row is 

 curved. The middle eyes are slightly separated ; the lateral 

 are placed further back, with a distinct space between them and 

 the middle eyes. The middle are nearly twice as large as the 

 lateral. The second row is plainly nearer the first than the 

 third row. The dorsal eyes are fully as large as the lateral. 



We found this genus upon (Phidippus) cyanidens, C. K., 

 Die Arachniden, XIII, p. 156. 



This genus finds its closest relations with Phidippus, Zeno- 

 dorus and Thyene. Zenodorus {which equals Ephippus, Thor.,and
