at base of both pairs of wings vermilion ; tergum

Tibicinoides cupreo-sparsus (Uhler) 



In addition to the species mentioned in the key there are two 

 others of which only the female sex is known. Okanagana hirsiita 

 Davis was described and figured in the Journal of the N. Y. Ento- 

 mological Society for March, 191 5, from a specimen in the collec- 

 tion of the American Museum of Natural History, labeled Santa Rosa 

 Island, California. It expands about 80 mm., and resembles a greatly 

 enlarged vanduzeei, but it is even more hairy beneath than in that 

 species; the front of the head is not quite as rounded, and the basal 

 cell of the fore wing is clear instead of clouded as in vanduzeei. Un- 

 fortunately in the original description the width of the fore wing in 

 hirsuta is printed 7 instead of 11 mm. The insect is shown correctly 

 in the figure. 



Okanagana rotundifrons Davis was described and figured in the 

 Journal of the N. Y. Entomological Society for September, 1916, 

 from a female in the collection of the University of Kansas taken in 

 Arizona. It expands 71 mm., and is a shining black and yellowish 

 species, with a conspicuously blunt and rounded front. 



Okanagana cruentifera (Uhler). PI. xix, fig. 2. 

 1892. Trans. Md. Acad. Sci., i, p. 161. 



In the United States National Museum there is a female from 

 " F, H. Hillman, Reno, Nev. 6, 21, 1890," labeled " Tibicen cruentifera' 

 Uhler, Cotype from Uhler's Coll." in the handwriting of Mr. Heide- 

 mann. No label by Uhler is on the specimen. It is spread; expands 

 75 mm., with the front of the head quite prominent, and the notch in 

 the last ventral segment double. According to the original descrip- 

 tion all of the cotypes came from Nevada. Another specimen in the 

 Uhler collection, captured after criientifcra had been described, is 

 labeled " F. H. Hillman, Reno, Nev. 7, 3, 98," and identified as 

 " Tibicen cruentifera Uhler, Nev." in Uhler's handwriting. This is 

 a spread specimen, expands 78mm. ; front is prominent; the pronotum 

 is almost entirely black, with a hair line of red along the hind mar- 

 gin; venation about the marginal cells not clouded. 



A male in the U. S. National Museum is labeled simply " Nev.," 

 and on a separate label " P. R. Uhler collection." This may be one
