New or Little-known Exotic Tipulidae. 37 



the lateral portions pollinose. Pleura black. Halteres yellow, 

 knobs brown. Legs with the coxae black, sparsely pollinose; 

 trochanters black ; femora obscure brownish yellow, the tips passing 

 into dark brown; tibiae brown, the tips darkened; tarsi brown. 

 Wings subhyaline; stigma oval, dark brown; narrow, pale brown 

 seams along the cord and outer end of cell \st M2 ; cells C and Sc 

 at the wing- base a little yellowish; veins brown. Venation: Scl 

 ending opposite the origin of Rs, Sc2 very far from the tip of Scl, 

 being about mid-distance between arculus and the origin of Rs; 

 Rs arcuated, nearly four times r; r near extreme tip of Rl, on 

 R2 + 3 about twice its length beyond the fork of Rs; deflection 

 of R4: -{- 5 strongly arcuated; cell 1st M2 closed, about as long 

 as vein Cul beyond it; basal deflection of Cul immediately before 

 the fork of 31; anal angle feeble; basal cells of mng not con- 

 spicuously developed. 



Abdominal tergites dark brownish black, the pleural membranes 

 paler.

Holotype, $, 1864 {Lindig), " Novara Eeise." 



Type in the collection of the Vienna Museum. 



Peripheropfera glochinoides is related to P. teucliolahoides 

 Alexander (Peru), differing in the colour of the legs and 

 the venational details, such as the position of Sc2 and the 

 length and position of the radial cross-vein. 



Rhamphidla rubicunda, sp. n. 



Similar to R. sanguinolenta Alexander ; wings with r — m obliterated 

 by the contact oi R4: -\- 5 on 311 + 2. 



Male. — Length about 5*8 mm. ; wing 5*8 mm. 



Generally similar to R. sanguinolenta Alexander (Amazonian 

 Peru), dift'ering as follows : 



Thoracic pleura concolorous with the mesonotal praescutum. 

 Femoral tips very gradually darkened, not abruptly as in sanguino- 

 lenta. Wings with no brown seam along vein 2nd A or the outer 

 end of cell 1st 312; seams along the cord less distinct ; r — m obliter- 

 ated by the punctiform contact of i?4 -f 5 on Jl/1 + 2, the basal 

 deflection of i?4 + 5 being a little longer, the deflection of il/1 -f 2 

 much longer than in sanguinolenta ; cell 1*^ 312 large, irregularly 

 pentagonal; basal deflection of Cul immediately beyond the 

 fork of 31. 



Abdomen more uniformly reddish. 



Hab. Paraguay.
