the ocelli. Cheeks almost eutirely smooth, occiput coarsely punctured. Clypeus 

 with an inverted T-shaped white mark, the arms very slender as compared with 

 those of other species. A dot ahove the lateral portions of the clypeus, and a 

 slender mark along the inner orbit of the eye about the height of the antennse, 

 also base of mandibles white, remaining portion rufous. Labrum entirely dark, 

 sometimes ferruginous. Thorax closely punctured, smooth on the disk and with 

 five distinct grooves, the lateral ones much shortened anteriorly. Scutellum with 

 sparse, medium sized punctures, postscutellum finely and closely punctured. 

 Metnthorax with punctures of various sizes, those on the truncation being much 

 the finer. The upper surface bears a short median carina. First segment of 

 abdomen almost impunctate, next two finely and closely punctured, remaining 

 segments rugose, last segment pointed and with a fringe of light hairs, each seg- 

 ment having a narrow black margin. Venter thinly pubescent. Legs green, 

 tarsi and extreme portions of tibige ferruginous. Anterior tibife with a whitish 

 stripe in front extending the entire length, femora with a white spot on the outer 

 side. Pleura with thin white pubescence. Wings hyaline, faintly clouded at the 

 tips, iridescent. Tegulse light brown, tubercles green. 



Described from two 9 specimens from Belize, British Honduras, 

 received from Mr. C. F. Baker. 



Tliis is a *very pretty species, easily recognized by the golden- 

 green color, puncturation and clypeal markings.

 yellowish spot, with a very few coarse punctures, smooth on the disk. Mandi- 

 bles and labrum black. Face very sparsely punctured, antennse black, rufous 

 beneath. Cheeks finely and very sparsely punctured, occiput much more closely 

 so. Mesothorax also finely and sparsely punctured, impunctate on the disk, and 

 with five longitudinal grooves. Pleura with a large impunctate area above. Scu- 

 tellum sparsely punctured, postscutellum more densely so. Upper surface of 

 metathorax roughened anteriorly, exceedingly minutely punctured on the trun-

Type locality, Wilson Peak, Los Angeles County, California, 

 altitude 6000 ft. ; also from Tehachapi Mts., altitude 4000 ft.. Dr. 

 A. Davidson collector; one specimen from Claremont, California, 

 C. F. Baker collector. 



This species presents a dimorphism, in the shape of cheek spines, 

 similar to that found in some species of the genus Perdita.
