Genera of the Famihj Atti'doe. 335 



Eyes very unequal in size, disposed in four transverse lines of two each, 



and almost of same length. 

 Maxillae rather short, slighty divergent, and much the broadest at their 



extremities, wliich are rounded. 

 Lip short, small, and of a somewhat curviangular form. 

 Leg's rather slender and moderately long; those of the first pair longest; 



and of the second pair shortest. 

 Abdomen small, short, oval, and sloping from its most convex part, near 



the margin to the spinners. 

 This genus is closely allied to Lyssomanes Hentz, as well as to JelsJcia 

 Tacz. It differs, however, from both in the shortness of the cephalo- 

 thorax and also of the abdomen. From Lyssomanes Hentz it differs in the 

 superior and inferior spinners being of equal length, whereas, in that 

 genus, those of the superior pair are much longer, slender and three- 

 jointed. 



Dr, L. Koch's suggestion that Athamas is probably identical with Evenus 

 of Simon (Arachniden Australiens, p. 1076), seems to us an error, since the 

 genera differ in several (Characteristics, In Cambridge's genus the cepha- 

 lothorax in front is very convex; the sides of the head are parallel, the cly- 

 peus as ivide as the middle eyes of the first row; the first leg longest. In 

 the genus of Simon, the cephalic part is plane, the sides of the head con- 

 verge behind, the clypeus is only one half the diameter of the large middle 

 eye; the third leg longest.
