66 INSKCUTOR INSCITL=e MENSTRUUS 



conspicuously convergent anteriorly, due to shorter face in 

 female, which in turn is due to shorter antennae. The genus 

 may be distinguished at once from Dolichogonia, another doli- 

 chocephalic form of the same group, by the facialia being wid- 

 ened and flattened, and the palpi and postvertical bristles short. 



Dolichocnephalia puna, new species. 



Length of body, 9 to 10 mm. ; of wing, 7.5 to 8 mm. Five 

 males and eight females, March 6 and 7, 1914; one female, 

 May 7, 1914, Oroya, Peru, over 13,000 feet, on short herbage 

 in Rio Mantaro Valley above town (Townsend), a pair in 

 copula March 6, 



Black, first two antennal joints rufous, palpi and epistoma 

 fulvous. Face, cheeks, and front silvery-white burnished, the 

 parafrontals showing the dark ground-color and a faint brassy 

 tinge in oblique lights. Frontalia blackish. Mesoscutum pol- 

 linose with pale golden, leaving four heavy equal black vittae, 

 uninterrupted and all reaching scutellum ; latter rufous to tes- 

 taceous, narrowly blackish on base and sides. Abdomen show- 

 ing silvery pollen on first three segments, the pollen fainter on 

 third; with ill-defined median vitta of old-gold. Hind tibias 

 testaceous. Wings nearly clear, faintly tawny on extreme base. 

 Tegulae nearly white, the narrow margins tawny. 



Holotype, female; allotype, male, on same pin, being the 

 pair in copula and still united. No. 19416, U. S. Nat. Mus, 



Germariopsis, new genus. 



Genotype, Germariopsis Townsend, new species. 



Differs from Dolichocnephalia as follows : Head only a little 

 elongate, para facials only two-thirds eye-width. Front tarsi 

 of female not widened. Claws of male no longer than last 

 tarsal joint, but little longer than those of female, front ones 

 a little longer than others. Apical cell rather long-petiolate to 

 short-petiolate, rarely closed in margin. Last section of fifth 

 vein almost always conspicuously less than one-half length of 

 preceding section. Second" aristal joint much longer, in male 

 often nearly as long as third. Cilia of facialia in both sexes 

 weak, often straggling and even vestigial.
