Aedes lazarensis Felt & Young. 



Culex la:;arensis Felt & Young., Science, n.s., xx, 312, 1904. 



Normally this is a medium sized mosquito, the mesonotum 

 with dark yellow scales, two moderately broad dark brown 

 median stripes and short posterior sublateral ones. A variety 

 occurs in which the sides of the mesonotum are grayish, the 

 yellow disk suffused with a brown shade, especially between 

 the lines. This is indistinguishable from the corresponding 

 aberration of punctor. This form occurs in the Rocky Moun- 

 tains almost to the exclusion of the normal form. 



The male genitalia as tabulated by me (Ins. Ins. Menstr., vi, 

 78, 1918) are incorrect. The apical lobe of the side piece is in 

 fact well haired, the specimens which I had before me being 

 in fact decticus, misidentified. The table may be corrected as 

 follows : 



23. Apical lobe of side piece weakly and sparsely setose 24 



This lobe more strongly setose 25 



24. Adjacent setae of basal lobe nearly as long as the spine, 



prodotes Dyar 

 These setae shorter and weaker decticus Howard, Dyar & Knab 



25. Spine of basal lobe situated AisiaWy Jaho'cnsis Dyar, altiusculus Dyar 

 Spine of basal lobe situated basally 26 



2(i. Setae on basal lobe many, much shorter than the spine, 



lazarensis Felt & Young 

 These setae sparse, not much shorter than the spine, .pionips Dyar
