three-jointed hind tarsi will separate it from Miimmicia (the 

 male of which is unknown). 



Hemerotrecha californica n. sp. Head, mandibles, and palpi pale red- 

 dish ; the tarsi and the greater part of metatarsi of the latter blackish ; 

 eyes on a black spot ; legs brown, the first pair reddis.h on basal joints : 

 abdomen and posterior segments of the thorax blackish, tinged a little 

 with purple. Mandibles as long as the cephalothorax, their basal parts 

 above and on the outer side beset with numerous stout spines, longer 

 bristles and spines near the base of the upper finger; the inner side of the 

 mandibles near the fond with long bristles and feathered hairs ; on the 

 inner side of the upper finger (of (^) is the long and slender flagellum of 

 two pieces lying alongside the finger. The upper finger (of (^) is as 

 long as the basal part of the mandible, quite straight, but bent down at 

 tip, and without teeth. The lower finger is not quite as long as the 

 upper ; on the basal half are four teeth, the end ones quite large, the 

 two middle ones much smaller ; beyond these teeth the edge of the 

 finger U distinctly although finely serrate. There is one large and 

 several small teeth on the fond of the mandibles. The palpi are quite 

 short, and stout, not tapering ; they are very hairy, and the tibia and 

 metatarsus have each two spines on the lower inner side and one or two 

 beneath ; there are no papillae. The legs are slender, the hind pair 

 longer than usual ; they are all very hairy ; the hind tarsi are slightly 

 covered ; the hind tibia has above at its base one, and at tip two tactile 

 hairs, each as long as the joint. The abdomen is about twice as long as 

 the cephalothorax, and moderately slender. 



I have not seen an adult female. Length, 10 mm. Found 

 near Pacific Grove, California, by Dr. Harold Heath, who says 

 that they run about in the blazing hot sunshine.

 EPEOLUS. 



This genus is very well represented in the Texan fauna, its 

 numerous and somewhat variable species being quite difficult 

 to separate. The following dichotomy will serve to identify 

 them with tolerable certainty. 



Legs and antennal scape wholly black 2 



Legs and scape more or less ferruginous 4 



2, Mesonotum with two short buff lines on anterior middle.

Mesonotum with a wide crossband of light yellow anteriorly .... 3
