Alloraphidia dorfi, new species 
Figure 1. 
Fore wing: length 9.5 mm., width 1.6 mm.; pterostigma light 
yellow (as preserved), short and broad and traversed by a single 
oblique veinlet; MP with four definite terminal branches; CuA with 
three branches. Hind wing length 9.0 mm., width 1.8 mm.; ptero- 
stigma as in fore wing but slightly narrower; CuA with a distal 
fork; cross veins shown in text-figure 1. 
Figure 1. Alloraphidia dorfi, n.sp. Drawings of fore and hind wings, 
based on holotype. Length of wing, 9.5 mm. Cretaceous of Labrador. 
Holotype: No. 87269, Invertebrate Paleontology collections, 
Princeton University. The specimen is preserved in a piece of hard, 
ferruginous argillite, collected at Redmond No. 1 deposit in Knob 
Lake District (near Schefferville) , Labrador, Canada. Collected 
by Professor Erling Dorf in 1958. This deposit is apparently late 
Albian (Early Cretaceous) or Cenomanian (Late Cretaceous) in 
age, very nearly at mid-Cretaceous. 
The specimen consists of a pair of fore and hind wings virtually 
complete; the wings are almost perfectly superimposed but with just 
enough discrepancy so that the main veins can be followed separately 
for each wing, except for the anal area of the hind wing. The preser- 
vation is excellent; the pterostigma is light yellow, as in many Recent 
snake-flies. 
On the basis of the wings, Alloraphidia seems to be much closer 
to the Mesoraphidiidae than to the Recent families of the order.
