Paleozoic entomofauna, there is a need for a systematic search for 
new localities in New Mexico and other western states. 
In the summer of 1975 we searched for insect fossils in the Man- 
zanita Mountains, in a clay pit SE of Albuquerque, on New Mexico 
highway 10 (14 on some maps). In these deposits, presumably of 
late Pennsylvanian (Virgilian) age, five insects had previously 
been found by the paleobotanist Dr. S. Mamay (U.S. National 
Museum, Washington) and three were discovered by students of 
the Department of Geology, University of New Mexico, Albuquer- 
que. We found 20 additional specimens but neither the composition 
of the insect assemblage nor the state of preservation was good 
enough for detailed study and the deposit was judged not worthy 
of extensive excavation. The material was redeposited and com- 
posed almost entirely of more resistant fragments of wings and of 
cockroaches, the tegmina of which are too variable in venation to 
be useful for taxonomic purposes. 
However, on the same trip, during a visit to the University of 
New Mexico in Albuquerque, Dr. Barry Kues, Department of 
Geology, showed us and generously loaned interesting material 
that he found in Carrizo Arroyo, Valencia Co., about 22 miles 
SW of Albuquerque. The small but promising collection consists 
of two well preserved wings of Palaeodictyoptera (Calvertielli- 
dae and Syntonopteridae), two Protorthoptera, and several Blat- 
todea. The age of the Carrizo locality, judging from the plant fos- 
sils, is estimated as late Pennsylvanian (Virgilian), and this is close 
to the age of the two major European insect localities; the late Car- 
boniferous (Stephanian) locality of Commentry, France, and the 
early Lower Permian (Upper Autunian) locality in Obora, Czecho- 
slovakia. 
This paper is concerned wit the Palaeodictyoptera of the advanced 
family Calvertiellidae from New Mexico and from Czechoslovakia. 
The most notable character of the family is that many features of 
wing venation are suggestive of the Odonata: the simulated arculus, 
the “subnodal” cross veins, the general arrangement of the vein 
pattern, the serrated costa, the odonatoid character of the reticula- 
tion, the corrugation extended by intercalated sectors, the tendency 
to fuse R+M, the suppression of the CuA, and the development 
of simple, parallel and curved anal veins (Tillyard, 1925; Carpenter, 
1943; Kukalova, 1955, 1964; Kukalova-Peck, 1974). These fea- 
tures do not indicate an immediate phylogenetic relationship with
