In the other species the black color of the dorsum does not lend 
itself to such thorough examination as does the pale color of the 
other two, but probably the depression may be distinguishable 
under favorable conditions. Similar bristles are present in 
Pseudohippelates Malloch, and probably in other genera not 
available to me at present. 
Two of the species now under consideration fall to be placed in 
Botanobia (Oscinis auct.), while the other is referable to M adiza 
(Siphonella auct.). I consider the presence of the bristles does 
not have sufficient importance to warrant the erection of a new 
genus for the species. 
Botanobia (Oscinis) bispina sp. n. 
Male and Female-—Black, obscured by dense grayish pruinescence. 
Head yellowish testaceous, front portion of frons slightly ferruginous, 
-ocellar triangle and back of head dark gray, the former slightly shining; 
antenne yellow, third joint, except at base and below, infuscated; pro- 
boscis fuscous; palpi pale yellow. Thorax slightly shining, gray pruinose 
except on anterior declivitous portion, and lower half of pleura. Abdomen 
slightly shining, yellowish on basal two segments and venter. Legs yel- 
low, fore coxz, all of femora except bases, and a broad band on basal 
half of hind tibize fuscous. Wings clear. Halteres white. 
Frons slightly over one third the head width; triangle as wide as vertex, 
extending slightly beyond middle of frons; orbits each with about 6 setu- 
lose hairs; interfrontalia with weak hairs; antenne large, third joint 
rounded at apex; arista pubescent; cheek about one fourth as high as eye, 
not produced anteriorly; vibrissa weak. Mesonotum sparsely haired, 
smooth and impunctate; the two large intrahumeral bristles directed lat’- 
erad; no intermediate prescutellars present; scutellum convex, rounded in 
outline, with 2 long apical bristles and 2 short lateral hairs on margin, disc 
with a few short setule. Wings and legs similar to those of covendix 
Fitch. Length 1 mm. 
Type locality, Urbana, Ill., September 20, 1916. A pair taken 
in copulo. In general color and habitus closely resembles coven- 
dix Fitch, but that species lacks the anterior thoracic bristles. 
Botanobia (Oscinis) spiniger sp. n. 
Female.—Yellow, subopaque. Back of head except on lower fourth 
gray; triangle grayish on center; third antennal joint black except below; 
arista black. Disc of mesonotum fuscous on posterior half, the dark color 
carried more or less distinctly forward in narrow lines, so as to give the 
disc the appearance of having 4 short yellow vitte; scutellum fuscous on 
disc; pleura entirely pale. Dorsum of abdomen largely fuscous. Legs 
yellow, fore tarsi fuscous. Wings clear. Halteres pale.
