 J his species was g-athered at the half way station 

 near Wa Wa, Utah, west of Frisco, at 7000 feet alt., on a bare 

 knoll among the junipers, soil apparently not alkaline. 

 Cymopterus globosus Watson. 



Coulter & Rose on page 183 state that this is a very rare 

 ppecies. On the contrary, it is one of the most common species 

 of the genus and abounds from the Fish Springs mountains, 

 western Utah, to the Sierras and southward at least to Gold- 

 Held. The fact that they have seen so little material of this 

 species is probably the reason why they have not also given it 

 a new name under their genus Rhysopterus, as it is closely 

 allied to C. corrug-^tiis and has the same corrugated wings in 

 varying degree. They certainly err in placing C. corrugatus 

 and Rhyspoterus Jonesii in that genus if their figure of the 

 type species of that genus is correctly drawn, as these two 

 species have nothing in common with it. The wings of these 

 species ar^ thickest at oase of cross section, oblong in outline 

 till near the edge and then they grow thin and sharp as is 

 common in the C. purpureus group. They err again in re- 

 frrrirg C. megacephalus as a close relative of C. globosus, as 

 they hive little in common. C. megacephalus is evidently re- 

 lated to C. Newberryi and that group having the wings re- 

 duced to a knife-edge close to the fruit and then widening as 

 shown by me in Zoe. 



Cymopterus corrugatus Jones. This rarest of the Cy- 

 mopteri has been obliterated in its type locality. It has never 

 been collected in ripe fruit but once. I made a special trip to 

 the type locality to get it in good fr<iit, but it is gone. I gath- 

 ered it fortunately in nearlv ripe fruit at Mill City on drifting 

 p-^nd, and in 1907 in similar situations below Hawthorne and 

 Copperfield nrar there, but the fruit was not fully ripe. So we 

 are assured that some time the fruit will again be found ma- 

 ture. Its characters hold well as described, in all the new 

 specimens. The root is a tuber as in all the allied species, and
