middle with a projection toward the anastomosis; the thyridium with ;i nya- 

 line white spot, and one on thearculus. Venation very similar to H.flai i /« 

 hut the discal *-*-ll has a longer pedicel; tin- fore wings are broader and more 

 oblique on the outer margin than in thai species, and the membrane more 

 plainly granulate. The appendages are very similar, but tin- lower pair, 



longer and more prominent

ECCLIBOMYIA 8IMULATA, sp. nov. 



Type.— M. C. Z. L0,876. Nevada: Reno (H. K. Morrison . 



Pale yellowish; head and thorax with black bristles, two ocellar macro- 

 chaetae just obliquely hack of each ocellus; Legs with black Bpines; spurs 

 1-3-4. Fore wings with pale, unmarked costal area, elsewhere pale brownish, 

 densely mottled with rounded, whitish spots, often confluent; hind wings with 

 apical pari of veins dark. Venation about as in E. COn&persa, firsl fork reach- 

 ing back nearly opposite base of posterior anastomosis; radius scarcely bent 

 at the stigma. Male genitalia closely similar to those of E, con&persa, the 

 superior appendages are rather longer, and wholly pale, the median process 

 appears to be the same, and the middle piece with furcate process also similar, 

 as are likewise the lower lateral appendages, but instead of the intermediate 

 black processes of A", conspersa there are two sets of four bristle-like pieces, 

 tin' inner pair the longer. 



Ebrpanse 26 mm. 



The spur formula is unusual, but the similarity in genitalia shows 

 the ocellar macrochaetae to be a more valuable generic character. 



Xkophylax ORNATUS, sp. nov. 



Type.— M. C. Z. 10,875. N. H.: White Mts. (H. K. Morrison). 



Yellowish, with pale yellowish hair, some brown hair on sides of face and on 

 sides of the pro- and mesothorax. Legs with black spines. Fore wings with 

 pale yellowish hair, more golden near front margin, with large patches of white, 

 and some black hairs toward tip and in two large patches behind. The white 

 is in the apex of each apical cell and on base of second and third cells, the first 

 and second subapical cells are nearly all white, leaving a dark line, much wider 

 near tip, between them, the third subapical partly pale; a large pale area 

 from behind discal cell, widening out behind, and another over the basal anal 

 region. Hind wings pale, fringes nearly white. In structure and venation 

 similar to N. co7ici7inus. 



Expanse 27 mm.
