 [Myrmeleon immaculatus De Geer. 



"Ariz." (coll. Am. Ent. Soc. : 2 J^). 



These seem not to differ from typical examples from the eastern 

 States, the space between the subcosta and radius lacking the 

 row of dark spots. It seems not unlikely that the specimens have 

 been incorrectly labeled.] 



Myrmeleon immaculatus, variety occidentalis, n. var. 



(3\ 9 Similar to typical immaculatus but darker, the anterior wings 

 with fuscous cloudings along the radius and one at tip of posterior cubital 

 fork; sometimes also there are paler cloudings along the submedian vein 

 and more or less generally upon the transverse veins.

Type. No. 6882, U. S. National Museum. 



The type specimen is a ^ from Williams. 



Dr. Hagen, in his description of M. immaculatus,* speaks of 

 the space between the mediana (radius) and subcosta being black 

 ish, where not interrupted with yellowish. I do not find these 

 blackish spots in any specimens from the Atlantic States, while

 occur. Do not the western specimens which Dr. Hagen had
