palpus. The dark colored legs have some short snow white hairs 

 en the tibia and metatarsus, but are not fringed. The metatarsi 

 of the first and second, and the tarsi of the first, second, and 

 third have the Broximal ends li^'ht colored. 



We have two females from Chapoda, in the Smith collection. 



Ilyllus C. Koch, 1846. 



For illustration of H. pterygodes see Arachniden Australiens, 

 PL CXIII, figs. 6-7. 



In this geaius the species are large, with long bodies, and with 

 the first legs very long, only slightly thickened, and not hairy. 

 In some of the species, and especially in the males, there is a 

 bulging out of the sides of the cephalothorax. It is character- 

 ized by the high cephalic plate, like that of Amycus. Most of 

 the species of Ilyllus come from the Malay Archipelago but we 

 have one, pratensis P., from Guatemala and Trinidad. We 

 have also giganteus C. K., Walchncarii White, and pterygodes 

 L. K 



The cephalothorax is very high, having the quadrangle of the 

 eyes on a raised plate from which it slopes outward on the sides 

 and behind. It is contracted in front and behind, the widest 

 point being behind the dorsal eyes. The quadrangle of the 

 eyes is one-fifth wider than long, equally wide in front and be- 

 hind, and occupies two-fifths of the cephalothorax. The eyes 

 •of the first row are all separated and are large or moderately 

 large, the middle being less than twice the lateral ; they form a 

 slightly curved row. The second row is plainly nearer the first 

 than the third. The third row is not so wide as the cephalo- 

 thorax at that place. 



C. Koch founded this genus on giganteus in 1816. In the 

 same year White formed the synonymous genus Deineresis for 

 Walchnaerii. Hyllus quadrilineatus, Wagae, nerreanhii, min- 

 uius, fuscGmanus, Camhridgii, callitlierinus of Taczanowskii, 

 and Hyllus tenuipes of Keyserling are in our collection, but we 

 do not include them in this genus. 



The shape of Hyllus is more like that of Amycus than any- 

 thing else, but the spiders are much larger, heavier, and deeper
