 (Continued from p. 205.) 



Hydropsyche partita, n. sp. (Figs. 58-59.) 



Black; head and thorax with grayish white hair; palpi nearly 

 black; antennae yellow, with spiral black line; abdomen black 

 above, pale beneath ; legs pale yellow, anterior femora rather dark- 

 er. Wings brown, densely irrorate with whitish, nearly all over, 

 the apical part very plainly so, a longer pale mark on hind margin 

 before arculus; hind wings gray, darker on costal tip. Fork 1 

 longer than pedicel, fork 2 extends a little way on discal cell, fork 

 3 with short pedicel, median cross-vein its length out on median 

 cell; in hind wing fork 1 is very short, fork 2 a long distance on 

 discal cell ; male with eyes wide apart, not enlarged. 



Expanse 23 mm. 



From Switzer's Camp, San Gabriel Mts., June, Mt. Wilson, 

 10 Aug., and Pasadena, May, all California (Grinell) ; Pecos, New 

 Mexico, July, Aug., and Vineyard, Utah, July (Spalding). 



Hydropsyche venularis, n. sp. (Fig. 62.) 



Black; head and thorax with whitish hair; palpi very dark; 

 antennae yellow, annulate with brown; legs pale yellow. Wings 

 pale, the cubitus heavily bordered with dark brown or black, anal 

 also bordered, a large, elongate streak near stigma, sometimes 

 broken by pale spots, a black spot at end of fifst apical vein, apical 

 part of wing often infuscate, elsewhere dark spots, often along 

 veins, and some patches of gray hair, all marks tend to be longi- 

 tudinal; hind wings gray, tip darker. Eyes of male large, approxi- 

 mate. Venation as in H. scalaris. Male superior plate with 

 minute emargination, the second part of lower appendage very 

 short and broad, with bifid tip. 



Expanse 22 mm. 



From Washington, D. C; Great Falls, Va.; Dane Co., Wise; 

 St. Louis, Mo., June to Sept. I had thought this might be H. 

 reciproca (indecisa), but that species is near H. scalaris. 



July, 1914
