In the other species the femora are cyHn(h"ical or tapered, 

 and the tarsi cyhndrical and slender. 



Didineis nodosa Fox 



California: Mountains near Claromont, one male, (C F. Baker), [Cor- 

 nell Univ.]. 



So far as I am awai'e this is the second recorded specimen of 

 this species. 



Didineis texana (Cresson) 



Georgia: Billy's Island, Okefenokee Swamp, June, l',)12, one female, 

 (Cornell Univ. Expedition), [Cornell University]; Tybee Island, Jvdy 26, 

 1913, one female, (J. C. Bradley), [Cornell Univ.]. 



Didineis sanctacrucae new species 



9. Black; first three segments of abdomen rufous (mahoganj- red); tibiae 

 and tarsi brownish, the former with a pale streak in front; clypeus and basal 

 half of mandibles yellow (chamois); scape beneath whitish (pale olive buff). 

 Wings stained slightly fuscous, especially in the region just apicad of the 

 stigma. Head and thorax clothed with a noticeable short white pubescence. 

 Length, 7 mm. 



From a lateral view the front is prominently convex, the dorsal surface 

 of the head and the cephalic surface being in planes almost at right angles 

 ti) one another, which merge comparatively abruptly. Seen from above 

 the front is filled out to the level of the eyes, these not being prominently 

 raised above the surface of the head as in texana. The front and vertex 

 are more closely punctate than in texana, evenly throughout; there is no 

 median groove, but a slightly rai.sed median area just above the antennae; 

 the margins of the antennal sockets are nearer to one another than to the 

 eyes; the margin of the clypeus bears three rounded teeth, less prominent 

 than in texana. 



The thorax is sculptured almost as in texana, but tlie dorsum more closely 

 and coarsely punctate, opaque and not shining as in texana. Scutellum 

 sparsely punctate, smooth and polished medially; propodeum rugulose, its 

 dorsal surface with three longitudinal or oblique lines meeting in a rounded 

 point behind. 



This species is quite close to texana. In that species, besides the points 

 of difference noted above, the eyes are prominent, the dorsal surface of the 

 head more gradually rounded into the cephalic; the antennal orifices are 

 farther apart than their distance from the eyes; there is a slight median 

 depression on the front; the front and vertex are polished and more finely 

 punctured, and the abdomen is red throughout. 



Perhaps this species is really the female of D. nodosa Fox. 

 Habitat. — Santa Cruz Beach, California, two females, May 14 

 or 18, 1907, collected by the author.
