narrow line on each side of this grove ; a narrow marginal line of 

 brown. Sternum jet-black and shining, without hairs. Abdomen 

 above brown, a slightly darker indistinct median band on the anterior 

 half, a deep-black spot at each antero -lateral margin, and on each 

 margin of the posterior half of the dorsum a row of five small 

 spots of white hairs, the corresponding ones of opposite sides con- 

 nected by transverse lines of black; sides finely marbled with 

 brown and gray ; venter deep black including the epigynum and 

 the region in front of the lung slits, this black area converging 

 behind to the spinnerets and its lateral margins somewhat racemose. 

 Chelicera, labium and maxillce deep black and glistening as also 

 the under surface of the coxce ; the chelicera with few hairs and 

 with a reddish prominence at the supero-lateral angle. Legs 

 shining reddish-brown except the coxse which are black above and 

 below, femora unhanded; first legs unhanded and darker than the 

 others; distinct annulations of brown and black on the patellae, 

 tibiffi and tarsi of the third and fourth legs, less distinct annula- 

 tions on the second legs. Palpi blackish-brown. 



In alcohol the black on the venter shows indistinct lines of 

 minute brown spots converging toward the spinnerets. 



Comparisons. — This species in the form of the head is somewhat 

 intermediate betAveen Trochosa and Tarentula. It is very close to 

 Lycosa (Tarentula) modesta (Keys.), from which it differs: (1) 

 slightly in the form of the epigynum; (2) in the middle eyes of 

 the first row being much less than twice as large as the lateral, and 

 in that the eyes of the second row are separated from each other 

 by nearly their full diameter; (3) in the black color of the ster- 

 num and coxce and in different coloration of the dorsum of the 

 abdomen. It shows also close resemblances to i. charonoides n. sp., 

 particularly in the shape of the legs and the coloration of the 

 superior surface of the abdomen; but the head is much narrower 

 and its sides steeper in charonoides, and the two species differ in the 

 form of the epigynum and in the coloration of the lower parts,

Eyes. — First row narrower than the second, its lateral eyes very 

 slightly lower and a little smaller. Eyes of the second row about 

 ]^ times their diameter apart. Third row widest, its eyes as larg
