minute. Only one prominent oral bristle. Carina narrow, confined to upper part of face; 
face blackish brown. Cheeks brown; their greatest width one-sixth greatest diameter of 
eyes. Eyes with very fine, sparse pile. 
Acrostichal hairs in four rows; no prescutellars. Mesonotum and scutellum velvety 
black. Notopleural suture yellow; pleure velvety black down to a line from base of first 
coxa to haltere, pale yellow below this line. Legs pale yellow. Apical and preapical 
bristles on first and second tibiz, preapicals on third. . 
Abdomen yellow, each segment with a posterior opaque black band that is wider at the 
sides. 
Wings brownish tinged; veins dark brown, except at base, which is pale yellow. Costal 
index about 1.5; fourth-vein index about 1.8; 5z index about 1.4; 4c index about 1.3. 
Length of body 1.5 mm.; of wing 1.5 mm. 

Fig. 49.—Drosophila superba. Wing of type specimen. 
Specimens examined: St. Vincent, West Indies (Williston type material) ; 
Mayaguez, Porto Rico (F. E. Lutz); Port Antonio, Porus, Jamaica (C. W. 
Metz). Williston (1897, Kans. Univ. Quart., 6) has recorded the species 
from Brazil. 
This species suggests Mycodrosophila, but can not go in that genus because 
it has two well-developed dorsocentral pairs, and because the thorax has 
not the shape characteristic of Mycodrosophila. It also resembles the group 
typified by D. dubia, but has large postverticals and is dull in color. The 
four acrostichal rows are aberrant, and suggest Scaptomyza, but this form 
resembles that genus in no other respect. 
SPECIES OF DROSOPHILA RECORDED FROM NorTH AMERICA THAT ARE NOT LISTED ABOVE. 
. adusta Loew, to Scaptomyza. 
. albipes Walker, not recognizable from the description. 
. amena Loew, to Chymomyza. 
. ampelophila Loew, synonym of D. melanogaster Meigen. 
. annulata Williston, new name is D. annularis Sturtevant. 
apicata Thomson, to Scaptomyza; is a synonym of D. terminalis Loew. 
bellula Williston, new name is D. pulchella Sturtevant. 
bimaculata Loew, to Leucophenga. 
brevis Walker, not recognizable from the description. 
cellaris Linnzus, erroneous name for D. funebris Fabricius. 
. colorata Walker, not recognized. Suggests D. sulcata Sturtevant, and was so identified 
by Coquillett. 
. confusa Staeger, does not occur in North America. The material that has been so 
recorded is mostly D. affinis Sturtevant. k
