that species. It is closely allied, if not identical, with my 

 domifex, and though the markings are different they are not 

 any more, perhaps, than attains in different sexes of the Lyco- 

 sidce. 



The points wherein the male nidi/ex differs from the de- 

 scription given above are as follows : There is a dark band 

 one- third the width of the abdomen on the venter and the 

 whole coloring above and below on the body is darker ; a 

 noteworthy difference occurs on the legs underneath ; the third 

 and fourth joints of all the legs are darkest, getting lighter to- 

 ward the extremities, while in domifex the dark markings are 

 confined to the last three joints of the first and second pair of 

 legs. There are apparently no markings on the upper surface 

 of the abdomen in the alcoholic example under consideration. 



It is hoped a study of more material the coming summer 

 will bring forth new light on these interesting members of the 

 Lycosidw.

AcanthacUsis hageni n. &\>. 



Very similar to A congener, and may be best described by com- 

 parison with that species. The vertex is shining- blackCuot shiuing 

 In A. congener) And there are transverse lines of wliite hairs,and two 

 patches of them behind ; pronotum has two small spots in front far- 

 ther apart than in A. congener, and outside of them two others, near 

 the middle of each side is a large pale spot, and a transverse one each 

 side on the hind margin, (in A. congener there are two pale spots in 

 front, a row of three each side, and two transverse ones on the hind 

 margin); on the middle of mesothorax in fi*ont there are two large 

 oblique pale marks (in A cow^^ewer there are four subequal spots 

 forming a square) : on raesoscutellum the pale spots ai*e much 

 larger. The veins of the wings are less intei-rupted with pale and 

 those of the posterior part are almost wholly black. The wings are 

 narrower than in A congener, especially noticeable in the middle of 

 the hind border- The radial sector has ten branches, seven before 

 the last transversal before the pterostigma (in A congener there are 

 eight branches, five before the last transversal before the pterostigma.
