New genus and two new species of Tipulidae 
In the course of my collecting of Tipulidae I have taken a 
number of forms that appear to be new to science, but most 
of these are species that show no venational peculiarities, and 
need not be considered here. Finding it necessary to refer to 
the others by name, I give herewith brief diagnoses of them. 
Oropeza n. gen. Madial sector apparently two branched, its 
base very short, originating opposite the tip of the subcosta; 
median vein three branched, with a median cross vein closing a 
very narrow discal cell that is situated almost entirely beyond 
the inner line of cross veins, and vein M, is bent upward upon this 
cross vein. Legs excessively long, femur and tibia of equal length, 
and the first tarsal segment as long as both together; each tarsal 
segment as long as all the segments beyond it taken together. 
Paired valves of ovipositor of the female of very unequal length. 
Type Liptila amnulara Say. Was speees Ines lnc 
doubtfully referred to Dolichopeza hitherto. In venation it dif- 
fers markedly in the relation the deflection of Cu, bears to the 
first fork of the median vein, and in the retention of a median 
cross vein, and in some minor matters such as the relatively 
longer base of its radial sector. These differences may be 
seen by comparing figures 3 and 5 of plate 16. 
Dolichopeza americana n. sp. Osten Sacken has reported the 
occurrence of undescribed species of this genus in America, and 
one of them I found at Old Forge in August 1905. ‘That it 
is a true Dolichopeza will be seen by reference to the vena- 
tion of its wing as shown in plate 16, figure 5. 
Its expanse of wing is 21 mm. Its color is brownish, paler 
ventrally. Its antennae are of moderate length, with the brown 
flagellum consisting of 10 segments, slowly diminishing in 
length toward the tip and beset with a few stout, black hairs. 
The wings are of pale brown, with venation as shown in the 
figure just cited, the halteres are infuscated at tips. The legs 
are of the usual excessive length; femora and tibiae are brown, 
with white bases, and all the tarsus is white except the basal 
half of the first segment and the apical half of the fifth segment. 
? Dicranomyia whartoni n. sp. Expanse of wings 9.5 mm.
