THE CANADIAN ENTOMOLOGIST. 209 



palpi are very short, the patella and tibia somewhat enlarged, the fifth 

 joint longer than the third and fourth together. The cephalothorax and 

 abdomen are smooth ; the legs have many small spines, most prominent 

 on the enlarged parts of legs I. and III. ; tibia II. has three false articu- 

 lations. The legs of the female are longer and more slender than those of 

 the male. The abdomen of the female is larger and pointed behind, 

 while that of the male is somewhat truncate. 

 Southern California. 



Eurybunus, gen. nov. 



Eye-tubercle very low and smooth, cephalothorax with an elevation 

 on the anterior margin bearing a few small spines. The segments of the 

 dorsal shield of the abdomen are so closely united that their sutures are 

 hardly discernible. The femora, patellae and tibiae of legs I. and III. are 

 enlarged; femur II. barely twice as long as femur I., and a little longer 

 than the body ; metatarsus I. without false articulations. 



Eurybunus brunneus, n. sp. 



Length, 9 mm. ; femur I., 4 mm. 



Colour — Dorsum uniform brown, the margins of the abdomen a little 

 white ; venter grayish-white ; coxae, trochanters and part of the femora 

 yellowish, a band near tip of femur brown, the extreme tip whitish ; base 

 of patella brown, the tip white ; middle of tibia brown, the base and tip 

 white ; same with the metatarsus, except that the brown is not as dark ; 

 tarsi brownish ; palpi and mandibles yellowish. Body very smooth, 

 femora I. and III. with a few short scattered spines, similar spines on the 

 under side of tibiae and metatarsi I. and III., tibia with three false articu- 

 lations. 



Southern California. 



Leptobunus, gen. nov. 



Legs short, joints but little thickened, femur I. much shorter than the 

 body ; femur II. frequently not as long as the body. Eye-tubercle 

 narrow, usually smooth. L. califoi-nicus is the type. In this species the 

 palpal claw is smooth, and metatarsus I. has but one false articulation ; 

 lateral pore is very large and looks outward. In the two other species 

 the palpal claw is dentate, metatarsus I. has several false articulations, 

 and the lateral pore is like that of Liobunum. For these reasons the last 

 two species may form another genus.
