same size and about a twelfth of an inch long. The cephalo- 

 thorax is brown, varying in different individuals. The abdomen 

 is gray, with the muscular spots lighter than the rest. The 

 cephalothorax is long, narrowing gradually toward the head. 

 In the males there is a slender horn extending forward between 

 the eyes, a little thickened at the end and covered on the upper 

 side with stiff hairs in rows (fig. 376). Under this horn is a 

 smaller one about half as long and close against it (fig. 375). 

 In females the horns 

 are absent, but the shape 

 of the head and arrange- 

 ment of the eyes are the 

 same, except that the 

 eyes are closer together. 

 There are several other species of Cornicu- 

 laria, some with similar horns and others 

 with single horns on the heads of the 

 males. They are found under leaves in 

 winter, on plants and fences, and among 

 the flying spiders in autumn. , „

Ceratinopsis interpres. — Length about a interpres. — 377, head of 

 tenth of an inch. Color bright orange, ™t ale 378 ' end of palpus 

 with a little black around the eyes and the 



spinnerets. In the female the height of the head equals the 

 length of the mandibles, and in males it is greater. The size of 

 the sexes is about the same. The upper middle eyes are a little 

 larger and farther apart than the front middle pair, and between 

 them is a flattened space covered with stiff black hairs, longer 

 in the male than in the female (fig. 377). The male palpi have 

 the femur as thick as the femur of the first leg and the tibia 

 very short and wide, with a little recurved point on the front 

 edge. They live on low bushes in summer and under leaves 

 in winter.
