SYSTEMATIC ACCOUNT. 103 
I have not seen this species, so have reproduced Williston’s description 
verbatim. 
Group G. MISCELLANEOUS SPECIES. 
Drosophila vittatifrons Williston. 1896. Trans. Ent. Soc. London, 408. 
Arista with about four branches above and one below. Antenne yellow, third joint 
brownish. Front about one-third width of head, wider above; yellow, two dark-brown 
stripes converging below. Second orbital about three-fourths of other two. Only one 
prominent oral bristle. Carina large, not flat; face yellow. Proboscis yellow, palpi dark 
at tip. Cheeks yellow, with brownish spot below eyes. 
Acrostichal hairs in six rows; no prescutellars. Mesonotum yellow, with four brown 
longitudinal stripes and an interrupted pair outside of these. Pleurz and legs yellow. 
Abdomen black, yellow at base and on sides. 
Wings clear, except for a black spot at tip, reaching from second to fourth veins. Costal 
index about 2.2; fourth-vein index about 1.3; 5x index about 1.2; 4c index about 0.8. 
Length body 2 mm. 
Specimen examined: St. Vincent, West Indies, 1,500 feet (Williston type). 
The wing is figured by Williston (loc. cit., plate x1, fig. 152). 
Drosophila guttifera Walker. 1849. List. Dipt. Ins., 4, 1110. 
D. multipuncta Loew. 1866. Berlin. ent. Zeit., 10, 50. 
3, 2. Arista with about six long branches above and four below. Antenne brownish 
yellow, third joint darker above. Front nearly one-half width of head, wider above; 
yellow, ocellar spot darker. Second orbital about one-half other two. Three or four nearly 
equal oral bristles. Carina broad and flat, very slightly sulcate; face yellow. Cheeks 
yellow; their greatest width about one-third greatest diameter of eyes. Eyes thickly 
clothed with short pile. 
Acrostichal hairs in six rows; no prescutellars. Mesonotum yellow, with four shining 
reddish-brown stripes, one pair in the acrostichal region and one including each dorso- 
central line. Scutellum shining reddish-brown. Pleure yellowish-brown. Legs yellow, 
last joint of each tarsus brownish. Apical and preapical bristles on first and second tibie, 
preapicals on third. 
Abdomen shining dark yellowish-brown, each segment with four black spots on its 
posterior margin. 
Wings with thirteen black spots, as follows: one at tip of second vein; one at junction 
of second and third veins; one on first section of third vein; one on anterior cross-vein; 
one at tip of third vein; three on third vein, dividing its last section into four nearly equal 
parts; one at each end of posterior cross-vein, these two united by a clouded region; one 
just before tip of fourth vein; one on fifth vein under the penultimate section of fourth 
vein; one in middle of last section of fifth vein. Costal index about 2.0; fourth-vein 
index about 1.5; 5x index about 1.3; 4c index about 1.1. 
Length body 2 mm.; wing 2.2 mm. 
Specimens examined: Monument Beach, Woods Hole, Massachusetts; 
Cape May, New Jersey (H. L. Viereck); Bloomington, Indiana (F. Payne); 
District of Columbia (Osten Sacken, type of multipuncta); Falls Church, 
Virginia (N. Banks); North Carolina (U. 8. Nat. Mus. coll.); Gulfcrest, 
Kushla, Alabama; Fort Worth, Texas (W. S. Adkins). Walker described 
the species from Florida. It is rare in the northern part of its range, but 
much commoner in the southern part. I have seen only two New England 
specimens, but found it rather common in Alabama. It is apparently 
rare near Washington; Dr. Payne was able to get only one specimen at 
Bloomington; yet Mr. Adkins reports it not rare in Texas. 
The species is to be found about fleshy fungi, from which both Mr. Adkins 
and I have bred it. Either gill-fungi or pore-fungi will serve for its develop- 
ment. 
Drosophila calloptera Schiner. 1868. Novara. 
o, @. Arista with about seven long branches above and four below. Antenne pale 
yellow. Front pale yellow; nearly one-half width of head, wider above. Second orbital
