LioBUNUM, Koch 



The three species known to me may be separated as foUows, applying 

 especially to the males : 



Palpus with tibia, patella and tip of femur dark brown, 



dorsum mostly blackish exilipes. 



Palpus and dorsum paler. 



Spinules on venter and coxae, trochanters brown, a brown 



median stripe on dorsum .pacificum. 



Only stiff black hairs on coxfe and venter, trochanters pale, 



a large cruciate mark on the abdomen .parvulum. 



Liobufmin pacificum, nov. sp. 



Length, $ 4.2 mm.; femur I. 5.8 mm., tibia I. 4.5 mm., femur IV. 

 9 mm., tibia IV. 6.8 mm. Dorsum, dirty white to gray, with a 

 broad median brown stripe above, which is nearly equal in width 

 throughout, barely wider at middle of abdomen ; two diverging white 

 stripes run from the eye-tubercle to the anterior margin of the cephalo- 

 thorax ; a few brown spots on each side of cephalothorax ; venter coxae 

 and palpi whitish ; legs dirty white, trochanters brown, patellae and tips 

 of femora and tibiae light brown, tarsi brownish ; basal joint of mandibles 

 with a brown hne above. Eye-tubercle moderate, with a few blunt pro- 

 cesses above. Palpus with spinules, largest on femur ; none of the joints 

 have their angles prolonged ; tarsus nearly straight, as long as patella plus 

 tibia, claw with a few small teeth near base. Dorsum of abdomen granu- 

 late. Coxae, trochanters, sternum and ventral segments with spinules ; a 

 white spine on inner tip of coxae I. and II. ; legs with short stiff hairs, 

 three or four false articulations in metatarsus I., none in tibia II. 



9 length, 7 mm., femur I. 6.2 mm. Similar to the $ , but the brown 

 stripe is usually broken up into small patches on the cephalothorax, and 

 indistinct on the posterior half of the abdomen j the spinules on the palpi 

 are smaller, and there are but three or four on each side of each ventral 

 segment. 



Sometimes the legs are brownish and the dorsum suffused with brown. 



Numerous specimens, $ and $ , from Olympia, Washington. 



Liobununi exilipes. Wood, 



Phalangium exilipes, VVood, Bull. Essex Institute, Vol. VI., p. 23. 

 This was described from California and Nevada ; I have a number of 

 specimens which agree quite well with the description, but in most of 

 them there is a broad yellow band near the middle of the abdomen.
