1914] Malloch—Four New North American Chloropide 26 
Parectecephala is likely to be confused with Eutropha Loew, 
the genera being very close, if aristalis Coquillett belongs to the 
former. Becker includes this species in his genus, but I can 
see no reason for separating the type from Eutropha. The frons 
is unprojecting and in other respects the type agrees very well 
in habitus with EHutropha thalhammeri Strobl, which is repre- 
sented in collection United States National Museum. 
Botanobia (=Oscinis) marginalis sp. nov. 
Female: Yellow, slightly shining. Ocellar region, and back of head black? 
third antennal joint at insertion of arista slightly browned. Mesonotum black 
gray, four equally wide reddish yellow stripes begin on anterior margin and extend 
to beyond middle of disk, becoming wedge shaped posteriorly; margin of disk 
laterally, on the posterior angle, reddish yellow; humeri and lateral margin of disk 
at middle pale yellow; pleurz pale yellow, with a vertical black stripe on upper 
half below wing base, which joins a forwardly directed diagonal stripe extending 
to about midway up mesopleura, and another spot above hind coxa; scutellum 
black-gray on disk, the margin broadly pale yellow; postnotum black. Abdomen 
yellow, each segment with dark brown fore marginal band which is produced 
backward in center. Legs entirely yellow. Wings clear, veins brown. Halteres 
yellow. Hairs on body yellowish; bristles black. 
Frons occupying one-third the head width; triangle ill-defined; surface hairs 
numerous, short, black, those near eye margin rather setulose; antennz of normal 
size, third joint rather acute on upper surface at tip; arista barely longer than width 
of frons, pubescent; cheek at least half as high as width of third joint of antenna; 
eyes oval, distinctly pubescent. Mesonotum impunctate, the surface hairs short; 
scutellum with 4 marginal bristles, the apical pair largest, but barely longer than 
the length of scutellum; outline of scutellum rounded. Legs normal. Wings 
with third costal division slightly over one-half as long as second; veins 3-4 divergent. 
Length: 1.5 mm. 
Type: Cat. No. 15970, U. S. N. M. 
Locality: Biscayne Bay, Florida. (Mrs. A. T. Slosson.) One specimen. 
Botanobia (=Oscinis) proxima sp. nov. 
Female: In coloration almost similar to marginalis. Differing in the following 
respects from that species: The insect over all is more slender; the head is more 
elongate; the eyes are elongate oval, whereas in marginalis they are placed with 
their long axis diagonal to the line of the body; the mesonotum has the two center 
yellow stripes reaching to short of the middle of disk, and the outer two reaching 
to distinctly beyond the middle, in marginalis the stripes are of equal length; and 
the mesonotum is more distinctly shining, the pollinosity being less distinct in 
proxima. 
Length: 1.25 mm. 
Type: In collection of W. L. McAtee. 
Locality: Wallops Island, Virginia, June 1, 1913. (W. L. McAtee.)
