Culex saxatilis Grossbeck. 



Ctdex testaceus van der Wulp, Tidsch, voor Ent. (2), x, 128, 



1867. 

 Culex apicalis Adams (not Theobald), Kans. Univ. Sci. Bull., ii, 



26, 1903. 

 Culex saxatilis Grossbeck, Can. Ent., xxxvii, 360, 1905. 

 Culex frickii Ludlow, Can. Ent, xxxviii, 132, 1906. 



No adults were obtained, but larvae occurred at Winnipeg 

 Beach, Manitoba, in roadside puddles. The species is uridely 

 distributed in forested regions from ocean to ocean and from 

 Canada to Mexico. 



Culex testaceus van der Wulp was referred to Aedes in the 

 monograph. In this I think we were misled by Theobald's 

 action in identifying specimens with ringed tarsi as testaceus. 

 It is more probably a Culex and an earlier name for the present 

 species. The small size of the male, 2^ lines, as given by the 

 author, would seem to preclude any Aedes except cinereus, 

 which, of course, is excluded by the short palpi. Moreover, I 

 have a letter from Dr. C. Ritsema Cz, addressed to Mr. D. W. 

 Coquillett, Alarch 12, 1904, in which he says the type of tes- 

 taceus in the Rijks Museum van Natuuralijkehistorie at Ley- 

 den has the palpi slender, not dilated, and but one tooth on the 

 larger claw of the fore tarsi. These are characters of Culex, 

 not of Aedes. He ^ays further that there is no line of white 

 scales on the penultimate joint of palpi below, which would 

 make the species not restuans, but saxatilis. For the rest, the 

 scales on the upper side of thorax and abdomen are said to be 

 very pale yellowish v.diite and the tarsi are unicolorous. The 

 specimen is probably badly faded and bleached and the m.ark- 

 ings lost. An examination of the male genitalia mounted in 

 balsam would decide the question positively of what testaceus 

 is. Awaiting this possibility, I do not make the reference posi- 

 tively ; but the evidence at hand points strongly as indicated. 

 Unfortunately, the name testaceus is inappropriate and mis- 

 leading, for this mosquito when fresh is black, certainly not 

 testaceous. 



It would be much more desirable if Adams's appropriate
