SYSTEMATIC ACCOUNT. 103 



I have not seen this species, so have reproduced WiUiston'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. Antenna? 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. Pleurae 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 xiii, fig. 152). 



Drosophila guttifera Walker. 1849. List. Dipt. Ins., 4, 1110. 



D. muUipuncta Loew. 1866. Berlin, ent. Zeit., 10, 50. 



cf , 9 . Arista with about six long branches above and four below. Antennae 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. Pleurae yellowish-brown. Legs yellow, 

 last joint of each tarsus brownish. Apical and preapical bristles on first and second tibiae, 

 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 muUipuncta); Falls Church, 

 Virginia (N. Banks); North Carolina (U. S. 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 Mri Adkins 

 and I have bred it. Either gill-fungi or pore-fungi will serve for its develop- 

 ment. 



Drosophila calloptera Schiner. 1868. Novara. 



cf, 9 . Arista with about seven long branches above and four below. Antennae pale 

 yellow. Front pale yellow; nearly one-half width of head, wider above. Second orbital
