assymetrical, the right side longer than the left, and cleft to right; 



femora and tibias mostly black ; wings faintly brownish with fourth 



costal section three times third and second and third section of fourth 

 vein subequal. Length and wings 3.0 mm. 



Described from New York. Type in the Hungarian Na- 

 tional Museum. It is unique in having the hypopygium 

 longer on the right side than on the left, but with the cleft 

 on the right. I have not seen it. 



45. P. subnitens n. sp. 



d\ Bare, black, semi-shining species. Front and face silvery. 

 Antennae with second joint black, and third yellow, long, white acu- 

 minate (similar to Fig. 35). Thorax and scutellum gray pollinose, 

 more dense towards the metanotum ; humeri whitish-yellow ; halteres 

 yellow. Abdomen semi-shining, submetallic, greenish-black, gray 

 pollinose laterally, especially the fourth and fifth segments ; first seg- 

 ment with lateral comb of whitish bristles ; fifth segment as long as 

 third plus fourth, and narrowed apically ; hypopygium nearly sym- 

 metrical (Fig. 19) hardly half as long as fifth, cleft to right (Fig. 111). 

 Legs black, simple; knees, bases of tibiae, and tarsi yellow; flexor 

 series of femoral bristles microscopic or wanting. Wings short, hya- 

 line, without stigma (Fig. 182). Length, 2.8 mm. ; wings, 2.5 mm. 



9 . Similar, with front wider than face, silvery, but shining black 

 towards vertex. Thorax and scutellum less gray above, and abdomen 

 with slight general hoariness ; the straight yellow ovipositor (Fig. 112) 

 extends to apex of third segment, its base globose or very short coni- 

 cal, as long as the ovipositor. Fore femora with two minute basal 

 flexor bristles. Third costal section slightly shorter than fourth, and 

 the fifth about twice that of third plus fourth. Length, 2.8 mm. ; 

 wings, 2.3 mm. 



Type.— &. Alamogordo, N. M., May 12, '02 (Figs. Ill, 

 182, Viereck, A. N. S., No. 5028.) 



Paratype — A female from same locality (Fig. 112). 



This species has the legs simple, and the abdomen hardly 

 shining, but dull and of a submetallic luster, not opake or 

 obscured by any tinge of pollen, still in certain aspects it 

 seems more or less faintly hoary. I have also a male from 

 Yosemite Valley, Cala. (Cresson,A. N. S.), which approaches 

 this species, and is probably distinct. It is more robust 

 (3.3 mm.). The scutellum is more shining; the abdomen 

 has the bristle-like hairs more erect, and the hypopygium is 

 very assymetrical (Figs. 113. 183).
