46 STUDIES IN AMERICAN EPHYDRIDAE (DIPTERa) 
Notiphila floridensis new species 
This form is similar in many respects to loewi, and I am not 
sure that it is a good species, but it will probably deserve sub- 
specific recognition. 
Description. — Similar to loewi. Frontal orbits slightly converging. Face 
white, sericeous, with three to four distinct bristles on lower half of profile; 
profile concaved above. Cheeks twice as broad as third antennal joint. Abdo- 
men gray, contrasting wdth the ochreous mesonotum; segments three and four 
with median pairs of triangular spots. All tibiae and tarsi yellow, but fore 
tibiae sometimes discolored medianly; ciha of middle tibiae of male sub- 
erect. Wings grayish. Length. — 3.2 mm. 
Holotype. — cf ; South Florida, (Robertson), [U. S. Nat. Mus. 
No. 20723]. Paratype. — 1 9 ; topotypical. 
Xotiphila biseriata new' species 
In this we have another form similar to loewi but differing in 
the characters given below. 
Description. — Simitar to loewi but abdomen broader, more rounded and the 
spots large, not triangular, with little or no tendency to broaden along bases of 
segments. General color w'holly olivaceous with frons dark and face yellow. 
Mesonotum and pleura immaculate. Middle tibiae at apices and hind tibiae 
e.xcept extreme bases, black, as are also the apices of their tarsi. 
Facial bristles noticeably more separated, so that the series extends higher 
tow^ards antennae. Antennal arista with eight to nine hairs. CiUae of middle 
tibiae of male more erect and of their femora more dense. Wings, espe- 
cially second vein much longer, with second costal section four times as long 
as third. Length. — 4 mm. 
Holotype. — cf ; Sandusky, Ohio. [Ohio Univ. Coll.]. 
A female; Drayton Island, Florida, V, 9, 1894; labeled “N. 
unicolor Lw.,” which I have seen in the U. S. National Museum 
collection, may belong here, but I have not compared specimens. 
Notiphila cognata new' species 
This species is unicjue in having the tarsal fascicle yellow. If 
this character continues to hold, as it has done in the other species, 
the present species can thus be distinguished from all others 
belonging to this group. Unfortunately, I have seen only the 
type of this form. The general habitus is similar to hiseriata 
and the species probably belongs near it. The abdominal mark- 
ings may, in an extended series, be found to be arranged in 
four series of spots, as the type has suggestions of lateral spots. 
This form seems to be the nearest relative of the European 
cinerea Fallen, we have in America. I have seen European speci- 
mens of cinerea.
