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. Radial 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 Mg 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 T i p u 1 a a n n u 1 a t a Say. This species has been 

 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 w^ing is 21 mm. Its color is brownish, paler 

 ventrally. Its antennae are of moderate length, with the brown 

 flagellum consisting of iq segments, slowly diminishing rn 

 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.
