CRETACEOUS INSECTS FROM LABRADOR 
2. A NEW FAMILY OF SNAKE-FLIES 
(NEUROPTERA: ALLORAPHIDIIDAE)* 
By F. M. Carpenter

Among the twelve insects which Professor Dorf collected near 
Schefferville in Labrador is a neuropteron of the suborder Raphi- 
diodea. This is the first Cretaceous snake-fly to be found, though 
the group is known from older deposits, Permian as well as Jurassic 
(Martynova, 1961). The Labrador fossil has more in common with 
the Jurassic species than with the Tertiary and Recent families, 
Inoceliidae and Raphidiidae, but clearly represents a distinct family. 
Family Alloraphidiidae, new family 
Related to the Mesoraphidiidae. Fore wing very long and slender; 
pterostigma well-developed; Sc ending at mid-wing; Rs originating 
just before mid-wing; MA arising well after the fork of MP and 
coalesced with Rs for a short distance; CuA connected to M at its 
point of separation from R. Hind wing about the same size and 
shape as the fore wing; costal area narrower than that of fore wing; 
Sc terminating slightly beyond mid-wing; MA arising from R just 
beyond the origin of MP. 
This family differs from the Mesoraphidiidae not only in the ex- 
treme wing-length but also in having MA in the fore wing originate 
well beyond the point of forking of MP, and in having CuA con- 
nected to M at its point of separation from R. In the fore wing of 
the Mesoraphidiidae MA arises from M before or at the origin of 
MP, and CuA joins M distad of the separation of M from R. 
Alloraphidia, new genus 
Fore wing about six times as long as wide; costal area widest at 
about its middle; Sc directed away from the costa slightly in the 
apical region and giving rise to about six costal veinlets; Rs arising 
just 'basad of the end of Sc; Rs and MA each with three well-defined 
branches, apart from marginal forkings; CuA with a closed, sub- 
marginal cell. Hind wing: MA very close to MP at their origins; 
branches of main veins much as in fore wing. 
Type-species: Alloraphidia dorfi n.sp.
