the black (most conspicuous as a band on each side of the median one) 

 to their absence. The sternum is ghstening black, with few hairs. 

 The abdomen above blackish with an obscure narrow median brown 

 band, and on each side a row of 6-7 small whitish circular spots, the 

 largest of them most anterior, and the posterior ones transversely 

 connected by lines of brown; the sides are gray, streaked above with 

 blackish; the venter brownish-gray, with rows of small black dots 

 converging from the lung-books to the spinnerets, the region of the 

 genital aperture black, the lung-books yellow, the spinnerets blackish. 

 Chelicera and lahrum black (the latter yellow at its distal end), maxillce 

 reddish-brown. Legs reddish-brown; femora of the first pair and fem- 

 ora and tibise of the other pairs quite distinctly ringed with black and 

 buff. Palpi colored like the first pair of legs, but the tarsal joint 

 black. 



The 6" is thus very similar to the 9 , but differs in the ocular 

 arrangement and in the coloration of the legs. 



A good distinction from the allied L. sepulchralis Montg., in addition 

 to the differences of the genital organs, is the following: in charonoides 

 the dorsal contour of the thorax is straight, and the labium less than 

 half as long as the maxillge; in sepulchralis the dorsal outline of the 

 thorax is arched (the eye area being somewhat depressed), and the 

 kbium fully half as long as the maxillse. 



4. Lycosa stonei Montg. 



This species is very abundant at Crosswicks, New Jersey. 



5. Lycosa verisimilis Montg. 



Specimens were secured at Crosswicks, New Jersey. 



6. Lycosa arenicola Scudd. 



Specimens were secured at Wood's Hole. 



7. Lycosa scutulata Hentz. 

 Specimens from Wood's Hole. 



8. Lycosa cinerea (Fabr.). 



An adult 9 from Wood's Hole has a cephalothoracal length of only 

 5 mm. Numerous specimens from Cold Spring Harbor, Long Island, 

 New York, kindly sent by Miss Annie B. Sargent, are all very lightly 

 colored, with the abdominal markings very indistinct. 



9. Lycosa nidicola Emert, 



Additional specimens were collected at Crosswicks and Wood's Hole. 

 This is a very variable species in size and color. The dimensions of 

 mature 9 9 in my collection are as follows :
