behind which the dorsum is much spotted; in front it is black, with a few 

 spots on each segment ; the patellae of the legs are dark brown ; only in a 

 few specimens are the white lines in front of the eye-tubercle bent to form 

 a white margin ; the palpus has the tibia, patella and tip of femur black 

 only in the male.

Liobunum parvtdum, nov. sp. 



Length, $ 4 mm. ; femur I. 5 mm., tibia I. 4 mm , femur IV. 7 mm., 

 tibia IV. 5.2 mm. Dorsum grayish, with a large spot on abdomen in the 

 form of a Greek cross, mostly brownish, but paler within, the truncate tip 

 reaching just beyond the middle of the abdomen; on the cephalothorax sev- 

 eral dark brown patches, more or less connected; no distinct lines from the 

 eye-tubercle to the anterior margin ; palpi whitish, with a brown line above 

 on patella and base of tibia ; venter, coxae and trochanters white ; legs pale, 

 with broad brown bands at tips of femora and tibiae, less distinct ones on 

 middles of these joints; patelky brown, tarsi mostly blackish. Eye-tubercle 

 very low and smooth. Coxae, trochanters, venter, sternum, palpi and legs 

 with short stiff black hairs, no spinules, a white spine on inner tips of 

 coxae I., II. and III. Several false articulations in metatarsus I., three or 

 four in tibia II. Tibia of palpus straight, much longer than patella, 

 tarsus slightly curved ; about as long as tibia plus patella; claw with a few 

 fine teeth near base, none of the angles of the joints prolonged. 



9 Length, 1^ mm.; femur I. 4.2 mm. Similar to male; mandibles 

 slightly brownish, margin of abdomen deeper gray, ventral segments with 

 a few brown spots. The ovipositor is extruded; it is about half as long as 

 body, cylindical and ringed, blackish in the middle. 



Two males and one female, Olympia, Washington, 

 Leptobunus, Banks. 



I have several specimens of a species belonging to this genus, but as 

 they are all young, I will not describe them. 



HoMOLOPHUS, Banks. 



I would consider Mitopus (^/V^/.y, Thorell, as a Homolophus, though the 

 last joint of the palpus is longer than the two preceding ; a better 

 character for the genus is the presence of the two prominent supra-mandi- 

 bular teeth. Mitopus, Thorell (of which M. Morio, Fab., was made the 

 type), differs from Oligolophus in having no spines to the femur of palpus. 

 O. mQ7iiafius, Bks., would thus be a Mitopus. From Washington and
