The known distribution of the species in New Mexico is thus : — 



(1.) Mesilla valley, about 3,800 ft. above tide. — Hijalina, albipen- 

 nis, phymatce, martini, semicrocea, lateola, nitidella, austini.=S spp. 



(2.) San Augustine, on east side of Organ Mts. — Albovittata.= 

 1 sp. 



(3.) Santa Fe, about 7,000 ft. above tide. — Sexmaculata, canina, 

 foxi.=3 spp. 



Thus the species of each locality are different. 



P. luteola has been described in another paper ; it is easily known 

 by its entirely yellow color. The other new species are described 

 herewith. All the types are now in Coll. Amer. Ent. Society. 



Perdita phymatae n. sp. 9. 



About 4£ mm. long: head and thorax shining olive- green, scutel- 

 lum bluish, metathorax green. Abdomen shining piceous. 



Face without pale marks ; mandibles brown ; antennae dark brown, 

 last four joints of flagellum pale brown beneath. Crown of head 

 finely punctured. A distinct ridge between antennae, replaced pos- 

 teriorly by a groove, which extends to the middle ocellus. A short, 

 shallow groove near and parallel with inner margin of eye. 



Thorax very finely punctured, with a few scattered pale hairs. 

 Metathorax with a distinct fovea. 



Abdomen piceous, sparsely clothed with pale hairs at tip. 



Legs dark brown; wings hyaline, iridescent, venation brown. 



Recognized among the species with a dark face, by its dark brown 

 abdomen and legs. 



Hab. — The type was taken out of the clutches of an example of 

 Phymata fasciata Gray, at Las Cruces, N. M. , on the campus of the 

 Agricultural College, beginning of October. (Ckll., 2,492.) The 

 Phymata was on yellow (Composite) flowers, which it deceptively 

 resembles in color. 



Mr. Fox remarks that semicrocea, martini, sexmaculata, and phy- 

 matce are "all good and so distinct as to scarcely require comparison." 



Perdita sexmaculata n. sp. 9. 



About 5 mm. long : head and thorax shining indigo-blue; clypeus, 

 mesothorax, and scutellum black; prothorax slightly greenish in 

 some lights, in others blue. Ends of mandibles rufous. Scape black ; 

 flagellum dark brown, paler beneath. Face and clypeus with dis- 

 tinct but very sparse punctures.
