more extended. The hypopygidium is rounded at the apex and entire. The 

 male varies in size ; the size of the pale spot on the scutellum also varies ; 

 the width of the yellow on the pronotum is not constant ; the clypeus is 

 sometimes all black ; and the posterior tibiie sometimes have a narrow 

 black line above. 



Type locality : Claremont, California. Five males and eight females, 

 collected by Prof. C. F. Baker. 



This species is close to annulipes, Cress., but the venter, scutellum 

 and tips of the posterior coxre beneath are yellowish; and the abdomen 

 has distinct punctures — it is not "smooth and polished."

The apical antennal joint is very small. The type was collected 

 at Stanford University, California. I have seen three females collected by 

 C. F. Baker at Claremont, California. Two of the females have a small 

 pale spot on the scutellum. A male from Claremont, California, and a 

 male from the mountains near Claremont, collected by C. F. Baker, differ 

 from the female in having the bands on the dorsal abdominal segments 

 interrupted in the middle. The hypopygidium is rounded at the apex and 

 entire.

Female : Length, 6 to 7 mm. Anterior margin of the clypeus very 

 gently incurved; labrum fully as long as the clypeus, truncate at the apex. 

 Superclypeal fovea almost wanting ; middle fovea wanting; lateral ocellar 

 furrows almost reduced to a fovea ; orbital carina strong ; head behind 

 the ocelli more shining and more sparsely punctured than on the front. 

 The third antennal joint as long as joints 4 and 5. All the lobes of the 

 mesonotum closely punctured, the scutellum more sparsely so ; scuteliar 

 appendage punctato-granular; the tarsal claws deeply cleft, the inner tooth 

 somewhat the shorter. Abdomen very finely punctured, the sheath rather 

 broader than usual, rounded at the apex. Black ; posterior part of the 

 pronotum, teguhe, scutellum (sometimes reduced to a small spot), edge of 

 the basal plates and the posterior margin of all the dorsal abdominal seg- 

 ments (these lines are sometimes interrupted), yellowisli-wliite. Legs 

 black ; the apical 5 6th of all the femora beneath, the entire tips of the 

 femora, tibiae (the anterior pair have a black line above, and the posterior 

 pair have a black ring at the apex), and the tarsi (more especially the
