12 PEOCEEDINGS OF THE NATIONAL MUSEUM vol.72 



not elongate, being wider than long (14: 8), is transversely impressed 

 at about the middle, and is produced into two distinct lobes back of 

 the impression. These are cariniform and separated from each 

 other at the center. They project upward and forward so that 

 their posterior surface is almost parallel to the mesoscutum. The 

 posterior angles of the pronotum do not quite reach the tegulae and 

 the parapsidal furrows are not distinct, being shallow, convergent, 

 and not reaching to the hind margin of the mesoscutum. 



Female. — Length, 7 mm. Prevailing color black except as noted. 

 Head unusually large, black, except clypeus which is ferruginous 

 and mandibles which are testaceous with dark brown teeth, with 

 short white pubescence; vertex rugose with carina extending from 

 median ocellus to bases of antennae and two other carinae extending 

 parallel with the inner margin of the eyes down the face; antennae 

 testaceous except seventh to tenth joints, which are fuscous. (Fig. 

 22.) Prothorax testaceous, impressed in the middle, posteriorly 

 bilobed as described, pilose, slightly longer than pronotum ; mesoscu- 

 tum black, shining, sparsely pilose and punctate, parapsidal furrows 

 convergent, not deeply impressed and not reaching posterior margin ; 

 scutellum black, sparsely punctate and pilose ; postscutellum narrow, 

 transverse, black, polished; fore legs testaceous, middle and hind 

 legs much paler testaceous with black markings on coxae and inner 

 face of femora, the black area extending to the outside of the distal 

 third of the posterior femora; middle and hind tibiae and tarsi 

 almost entirely black to brown; the posterior femora testaceous 

 dorsally and on sides of swollen part, black on stalk and ventrally on 

 club; chela as in Figure 8; wings smoky, bifasciate, venation dark 

 brown. Propodeum black, pilose, rugose. Abdomen brownish, with 

 lighter brown markings, smooth, polished.

 Figs. 23 and 9 



This specimen is very similar in structure to variabilis but has the 

 following differences: 



Female. — Color black except scape of antennae, mandibles, inner 

 side of fore tibiae, fore tarsi including chelae, middle and hind tarsi, 

 which are fuscous to testaceous. The punctation on the pronotum 

 is finer and more even than in variabilis and it is not notched at 

 junction with mesoscutum; chela as in Figure 9; dntennae as in 

 Figure 23. The entire body is more or less clothed with short, fine, 

 white hairs. 



Type locality. — Chiricahua Mountains, Ariz. 



Described from one specimen collected by H. G. Hubbard.
