SPIDERS OF THE FAMILY ATTIDAE FROM AMES 227 



The writer has never seen any other than the alcohol preserved 

 specimens. These are all dull red in color. There are only 

 females in our collection all of them about six millimetres in 

 length. Following- is Peckham's description of color and mark- 

 ings : ' ' Cephalothorax brown with short white hairs. Abdomen 

 very variable; sometimes pinkish with white bands at base and 

 on the sides, and four pairs of white spots; sometimes brown 

 with many pale spots and curved bands; sometimes brown with 

 four pairs of black spots ; sometimes bronze with white hairs at 

 the base and on the sides, and two longitudinal black bands upon 

 which are three or four pairs of white dots. The clypeus is 

 white with other parts varying between light and dark brown. ' ' 

 This species is distributed over a large part of the United 

 States and Mexico. It is commonly found en small trees and 

 bushes. 



HABROCESTUM Simon 1876. 

 In this geniLs the cephalothorax is short and slightly bulging 

 on the sides. The ocular quadrangle is a little wider than long, 

 with the second row of eyes about midway between the anterior 

 lateral and the posterior eyes. The posterior eyes are separated 

 the width of the cephalothorax. The third pair of legs is longest. 

 The abdomen is oval-shaped. 



Habrocestum pulex Hentz 1846. 



One female collected by Osborn and identified by Banks 

 (1891) is in the collection. The markings have been destroyed 

 by their many years in aleohol. The following is Comstock's 

 description : 



"This is a small species, the male measuring only one-sixth 

 inch in length, the female a little more. In the male the cephalo- 

 thorax is reddish, dark in the eye-region, \\dth a narrow white 

 triangle pointing forward, and lighter behind the eyes; the 

 abdomen is dark bro\\Ti, with two longitudinal, nearly parallel, 

 light lines on the basal half and a broad transverse white mark 

 just behind the middle. In the female the cephalothorax is 

 dark, with a large triangular spot reaching from the eyes to 

 the hind end. The abdomen is dark, with either two light longi- 

 tudinal lines on the basal half, as in the male, or with several 

 irregular light spots in this region, and with a transverse light 

 band just behind the middle. Around and behind the band are 

 other irregular liglit markings."
