This species has been generally considered the Anopheles quadrimaculatus 

 described by Say in 1824, but it appears that the name in reality applies to the 

 form herein treated under the specific name occidentalis. This is apparent from 

 the distribution and from Say's locality, " North-west Territory." Unfortu- 

 nately we did not make this observation in time to introduce the necessary 

 corrections in the text. The present species should be known as Anopheles 

 guttulatus Harris. The name guttulatus was introduced without description 

 for a probable variety of quadrimaculatus, and its significance being clear by 

 association, it can be considered available. In 1864 Loew treated the species as 

 identical with the European Anopheles maculipennis Meigen, and also referred 

 his Anopheles pictus from Asia Minor as a synonym of it. American authors, 

 however, held it distinct, until Theobald, in 1901, again referred it as a synonym 

 to A. maculipennis. Blanchard and Theobald subsequently refer to our species 

 as the American form of maculipennis. Dyar and Knab, in 1906, again dis- 

 tinguished the species and adopted the name quadrimaculatus. Van der Wulp, 

 in 18GT, described a male collected by Thore Kumlien in Wisconsin as Anopheles 

 annulimanus, and this is said also to belong here. 



We are sceptically inclined toward the record from Vera Cruz, Mexico, by 

 Parker. Beyer and Pothier ; no fresh material of this species has been received 

 from tropical Mexico and we doubt that its range extends into the tropical zone.

Original Description of Anopheles atropos: 



Deep black; thorax obscurely lined with violaceous, especially posteriorly. Head, 

 abdomen and legs black, no markings on the pleurae. Wing scales outstanding, 

 uniform, not forming spots, though a little thicker at the usual points, indicating 

 the spottings. 



Allied to A. quadrimaculatus Say, but rather smaller, and deep black, not brown, 

 the abdomen without traces of the lighter bandings. 



Seven specimens, Florida Keys (Dr. Hiram Byrd).
