WASHINGTON FHALANGIDA, WITH DESCRIPTION OF A 

 NEW SOUTHERN LIOBUNUM. 



BV NATHAN BANKS, SEA CLIFF, N. Y. 



During the past few years Mr. Trevor Kincaid, of Olympia, Washing- 

 ton State, has kindly sent me many interesting arachnids from that region. 

 Among them quite a number of phalangids, some of which have been 

 described, others will be given in this paper. Previous to my descriptions 

 of Californian and Washington phalangids of last year, but one species 

 ( Liobujium exiiipes, WoodJ was known from the Pacific region ; I have 

 described and recorded fifteen others. These, with the four new ones 

 described below, make a total of twenty ; probably as many more remain 

 to be described. To an Eastern student this fauna is very interesting 

 because of the number of peculiar forms not known in the Eastern States. 

 The families and genera may be separated by the following table : — 

 ( A compound claw to posterior tarsi, palpi 



I < very spiny. , (Phalangodidae) Sderobunus. 



'All tarsal claws simple. -. 2 



f Last joint of palpus with a claw (Phalangidae) 6 



( Last joint of palpus without a claw 3 



j Palpi very short, coxae united (Trogulidse) Dendrolasma. 



\ Palpi long, coxae separate (Nemastomidag) 4 



( Mandibles longer than body Taracus. 



( Mandibles shorter than body 5 



f Palpi slender Nemastoma, 



1 The joints much swollen .Phlegmacera. 



\ Femur I. longer than body, palpal claw denticulate, lateral pore 



I oblong Liobiiuuin. 



Femur I. shorter than the body, palpal claw smooth, lateral 



pore nearly circular 7 



Eye-tubercle and anterior margin of cephalothorax 



spiny Homolophus. 



(.Eye-tubercle and anterior margin smooth Leptobtmus.
