Syrphus-fly. (Allograpta obliqua=Syrphus obliquus Say, Ent., 1, 
pleexints 2. ee ko. 93. 
This handsome golden fly was taken in great numbers in April, 
while hovering around flowers in the gardens. It is common in 
the middle and southern United States. It was recorded as common 
by Jones, 1876. 
In both sexes the fourth segment of abdomen has an oblique stripe 
of yellow on each side, and two dorsal stripes of the same. Eyes of 
male have an upper area of enlarged facets. The larva, which feeds 
on aphids, is pale green, with faint lighter stripes. It is a very 
beneficial species. See Fig. 936. 
A species of Forest-fly or Gad-fly (Zabanus) of rather large size 
and with a large green head, is also common. Uhler, 1888, recorded 
a different, smaller species, allied to 7. lineola Fabr. and 7. cincta 
Fabr. 
Robber-fly. (Asilus?) A Robber-fly belonging to <Aszlus or 
some allied genus is described in Miss Hayward’s notes. 
Mosquitoes ( Culex, etc., sev. sp., figs. 94-100) are very abundant, 
especially in the lowlands and near marshes in summer, but we found 
them by no means common in March and April. All those collected 
were species of Culex. Whether the Malarial Mosquito (Anopheles) 
occurs here is uncertain, but it has not been recorded nor is malaria 
endemic. According to Hurdis, one common species of Culex has

the legs conspicuously banded with gray and blackish. Another, 
abundant in the marshes, is a rather large species, of a nearly uni- 
form brownish color.
