and were seldom seen elsewhere. A few were found in a wood 
of walnut, maple, oak, hickory, and other hard woods, and one 
from an open grassy marsh on the borders of a belt of hard 
wood. Their chief locality is, however, indoors, except when 
ovipositing. 
Synonymy .—The first authentic name for this species appears 
to be Meigen’s A. maculipennis (1818). On the Continent Ficalbi, 
Grassi, and others call the species the A. claviger of Fabricius 
(1805). This is wrong, for the following reasons : Calex claviger, 
Fabr. (Syst. Anti. 1800, p. 35), appears never to have existed as 
a type specimen. Baron Osten-Sacken states that Fabricius had 
no specimens at all (Ento. Mo. Mag. p. 282, 1900). The name 
A. maculipennis was adopted by Loew in 1845 (Dipt. Beit. i. 
p. 4). I prefer to take Meigen’s description (in Syst. Beschr. 
1818), as I now fail to connect his species of 1804 (Klassif. p. 5) 
with his maculipennis of 1818. Meigen first clearly states con¬ 
cerning his species in 1804, “Die Fliigel sind ungeflecht ” (p. 5). 
Anopheles maculipennis, as we now take it from his world-wide 
work started in 1818, has spotted wings.
