anal unbranched. It was doubtless this mistake that led 
Ricker to describe his Hastaperla. Using the unbranched 
second anal vein as the generic character, our species 
( brevis ) belongs to Chloroperla as truly as apicalis and 
tripunctata. 
In 1912 when I saw the type of C. cydippe Newm. I noted 
it had a small anal area with one longitudinal vein ; recently 
Ricker has seen it and says the second anal is forked, so this 
species is doubtless an Alloperla. 
Kimmins considers that the genotype of Chloroperla ( lutea 
Latr. is a synonym of tripunctata . I cannot agree. Latreille 
says of lutea, “extremite des antennes noires” ; and Newman 
says of apicalis, “extreme portions of the antennae intensely 
black”. Neither mention any black border to the pronotum. 
Scopoli does not mention antennae in his description of 
tripunctata, which, he says, agrees except in some points 
with grammatica. Of grammatica he says, “antennae basi 
flavae, extrorsum fuscae”. Klapalek in Siisswasserfauna 
Deutschlands (1909) says for tripunctata that the basal 
third of the antennae is yellow, rest black, and that the 
pronotum is bordered with a black line. 
In specimens here (Hagen coll.) tripunctata has mostly 
brown to black antennae except basal third or less, while in 
apicalis (even specimens at least 90 years old) there is a 
greater part yellow and beyond “intensely black”. Since 
lutea agrees with apicalis in both antennae and pronotum 
and in neither with tripunctata, it is evident that lutea 
Latr. will replace apicalis. In either case brevis belongs to 
Chloroperla, and Chloroperla is distinct from Alloperla.
