the middle fiilljr twice as large as the lateral, all separated. 

 The second row is nearer to the first than to the third. The third 

 row is narrower than the cephalothorax at that place. So far 

 as vv^e know the relative length of the legs is 1342 or 1342 in the 

 male and 3412 in the female. 



Simon founded this genus on impcrialis Rossi, in 1876, call- 

 ing it Thya (Arachn. de Fr., Yol. Ill, p. 51). The name 

 Thyene was afterward substituted for Thya, which was preoc- 

 cupied. We have the type, from France, tamafavi Vinson, 

 from Madagascar, hiicculentum Gers. from Zanzibar and Mada- 

 gascar, and varians new from Madagascar. Simon has de- 

 scribed T. semicuprea, Bidl. Soc. Zool. de Fr., t. x, p. 4, and 

 T. squamulata, Ann. Soc. Ent. de Fr., 1886, p. 347. 



Thyene varians sp. nov. 



The males of this species are showy brown and white si)iders, 

 with a wide scalloped white band on the sides of the cephalo- 

 thorax, and white hairs on the upper part of the falces. The 

 female is indistinct.

$. Length 7 mm. Legs 3412, third and fourtli plainly 

 longest, and the first and second stoutest. The first and second 

 -are nearly equal in length, the third and fourth more unequal. 



The first row of eyes is nearly straight and the lateral eyes 

 are larger than is usual in Thyene, being more than half as large 

 as the middle eyes. The quadrangle of the eyes is a little mora 

 than one-fourth wider than long, and is only slightly wider be- 

 hind than in front. 



In the male the ground color is brown. The cephalothorax 

 has the clypeus and face white. There is a small tuft of black 

 hairs, on each side, below^ the eye of the second row. The 

 cephalic plate has a more or less triangular white spot in the 

 middle, and two short snow white bands running back from the 

 middle eyes of the first row to beyond the eyes of the second 

 row. Around the lower margin is a narrow white line, and on 

 the upper sides is a wide, scalloped, white band, which begins at
