Melanagromyza burgessi (Malloch) 
(Figs. 117, 118) 
Agromyza burgessi Malloch, 1913a: 
322. Holotype female from 
Massachusetts in USNM. 
Melanagro myza burgessi, Frick, 1959: 
363. 
Melanagromyza malefica Spencer, 1981: 
46, California. NEW SYNONYM. 
Although females in this genus are 
frequently not satisfactorily identifi- 
able, the large size, projecting 
frons, numerous orbital bristles, and 
dark squamal fringe satisfy us that 
the female holotype can be correctly 
associated with males seen from 
Illinois and California (as M. 
malefica ) . M. malefica is therefore 
now synonymized with M. burgessi . 
Melanagro myza caribbea Spencer 
(Figs. 129, 130) 
Melanagromyza caribbea Spencer, in 
Spencer and . Stegmaier , 1973: 34. 
Holotype male from Florida in USNM. 
The correct generic position of this 
minute species with a wing length of 
1.7 mm is problematic. It may well be 
a leaf or stem miner, but we hesitate 
to transfer it to Ophiomyia until its 
biology and larval characters are 
known. Even the aedeagus (figs. 129, 
130) does not clearly indicate the 
generic position. 
Melanagromyza chillcotti Spencer, 
new species 
(Figs. 75, 76) 
Head. Frons narrow, equal to width of 
eye, not projecting above eye in 
profile; 2 ors, 2 more widely spaced 
ori, orbital setulae sparse but in 2 
rows, inner row largely proclinate, 
row nearest eye margin reclinate; 
ocellar triangle well defined, apex 
extending only to level of lower ors; 
gena deepest in center, about 0.17 
vertical height of eye, this distinctly 
pilose in male; 3d antennal segment 
small, round arista appearing bare. 
Mesonotum. 2 dc, acr in some 8 rows. 
Wing. Length in male 2.1 mm, inner 
crossvein beyond midpoint of discal 
cell, last section of M 3+4 0.67 of 
penultimate . 
Color. Frons matt black, ocellar 
triangle and orbits distinctly but not 
brilliantly shining; mesonotum almost 
entirely black, with only faintest 
greenish reflections viewed from rear; 
abdomen distinctly green; squamae and 
fringe white. 
Male genitalia. Aedeagus as in 
figures 75, 76. 
Host/early stages. Unknown. 
Holotype m. , North Carolina, Macon 
Co., Wayah Gap, 4,100 ft, 29. VII. 57 
(J.G.C.), in CNC. 
Remarks. Although somewhat resembling 
both M. riparella and M. subvirens , 
the male genitalia are entirely 
distinctive. M. chillcotti also 
closely resembles M. chaptaliae but is 
distinguishable by the blacker 
mesonotum and the broader gena. 
Melanagromyza chillcottiana Spencer, 
new species 
(Figs. 79, 80) 
Head. Frons not or only slightly 
projecting above eye, 1.5 times width 
of eye; 2 ors and normally 4 strong 
ori, orbital setulae sparse, irregular, 
mainly proclinate; ocellar triangle 
only weakly shining; lunule large, 
higher than semicircle; eye in male 
pilose; gena deepest in center, 
narrow, about 0.14 height of eye; 
arista long, weakly pubescent. 
Mesonotum. 2 dc , acr in some 8 rows. 
Wing. Length in male 2.5 mm, C ex- 
tending strongly to M 1+2, last 
section of M 3+4 about 0.67 of 
penultimate . 
Color. Frons brownish black, ocellar 
triangle, orbits, and lunule somewhat 
paler; mesonotum matt black, though 
more shiniftg seen from rear; abdomen 
blackish coppery, only weakly shining;
