to be important. It may be that the famia of "equinoctial America" is, 

 to a large extent, a relic of past ages; "that it arose in a forest-clad earth 

 and has been driven before the more successful ground-inhabiting forms, 

 not that it has been slowly developing from ground- inhabiting forms in 

 the region in which it is now found. 



Lycosa is a large genus of world-wide distribution. Several attempts 

 have been made to split it up, with varying success. One of these puts 

 cinerea (Fabricius) in the genus Arctosa. This species has been found 

 in Europe, throughout United States, in Mexico and at El Guama, Cuba. 

 L. atlantica Marx was known only from Bermuda, but Mr. Banks writes 

 that he has seen it from Havana, Cuba. L. aussereri (Keyserling) is 

 known from f Colombia, Vieques and Culebra; L. hadia (Keyserling) from 

 Central America and Cuba; L. fusca (Keyserling) from Central Amer- 

 ica, Cuba (Havana, according to a letter from Mr. Banks) and Porto 

 Rico (San Juan) ; L. punctuJata ELentz, from United States east of the 

 Eockies and, according to a letter from Mr. Banks, Havana, Cuba. L. 

 insuJaris Lucas is known only from Cuba. We took it there at Guane, 

 Pinar del Rio, Bahos San Yincente, Cabanas and Guaiitanamo. Banks, 

 who now considers it to be a Pardosa, recorded it from Santiago de las 

 Vegas. 



Pardosa is likewise of world-wide distribution. In America it is best 

 developed in the north. There are a few species in South America, but 

 unless insularis be included the only West Indian species is yortoricensis- 

 Banks, which was described from San Juan, Porto Rico. AYe took it in a 

 ijiarsh at San Turce near its type locality. 



These two genera, while much confused in the literature, are placed in 

 different divisions of the family by Simon. Both are too generally dis- 

 tributed to be of a great deal of interest in a study of distribution. 



OXYOPID^ 



The members of this family run about the vegetation with great agility 

 in chase of their prey. There are only eight genera, of which six occur in 

 America. Of the remaining two, one is confined to Madagascar and one 

 10 India and Malasia. Two of the six American genera liave not been 

 reported from the Antilles ; one of them has but two species and is con- 

 fined to Brazil, and one has but one species, being confined to Cayenne, 

 as far as is known. 



Hamataliva has a wide tropical and subtropical range but in America 

 there are only four species kno^vn: two in Brazil, one in Mexico and 

 gri^ea Keyserling, which is reported from Lower California, southern 

 r^niterl States. Cuba (Santiago de las Veo-as) and Haiti.
