A REVIEW OF THE CHRYSOPIME 
(NOTHOCHR YSIDAZ) OF CENTRAL AMERICA 1 
By Nathan Banks 
Museum of Comparative Zoology 
Many years ago the writer described a few species from 
Central America, including Baja California. Since then Navas 
has published a large number of species. For some years the 
author has had a manuscript synopsis of the species in the 
Museum. In 1937 Professor Roger Smith visited the various 
European museums to study the types of Chrysopidse; he has 
given me a copy of these notes. With this most useful help I 
have felt emboldened to present tables to the species known to 
me, with descriptions of some new forms. 
Besides the specimens at the Museum of Comparative Zool- 
ogy I have seen those belonging to the American Museum of 
Natural History, the Academy of Natural Sciences of Phila- 
delphia, and the U. S. National Museum. 
As to classification, I have made an attempt to get away from 
dependence upon the divisory veinlet. 
In the Central American forms I see, outside of the Apo- 
chrysinae, three groups, one those represented by Nadiva and 
allies, in which the joints of the antennae are very broad, the 
thorax broad, the venation more or less irregular, particularly 
in the discoidal cell; the anal area of the hind wings is large 
and the branches of anal veins sometimes forked. The second 
group is that based on Chrysopa and allies in which the stigmal 
area is unmarked, and the medius of fore wing slopes down 
evenly to its marginal fork. This genus should be divided. The 
third group is that of Nodita and Leucochrysa, in which there 
is a dark mark at the base of stigma, and the medius curves to
