SUBSTITUTE NAMES FOR SOME EXTINCT GENERA 
OF FOSSIL INSECTS*

During the preparation of the hexapod volume of the Treatise on 
Invertebrate Paleontology, now in presst, several junior homonyms 
were noted among the extinct genera. This seems to be an appro- 
priate occasion to propose substitute names for these homonyms. In 
those instances in which the authors are still living, I have already 
called their attention to the homonymy, with the suggestion that 
they propose names of their own choice. In some other cases 
replacement names are already available, through synonymy, and 
these are being proposed in the hexapod volume of the Treatise. 
Most of the homonyms, however, require new names, and since the 
current editorial policy of the Treatise excludes the proposal of new 
names of taxa in that work, the present article is intended to meet 
that need. It consists of proposals of new generic names to replace 
certain names that are not being taken cafe of elsewhere. The gender 
of each new name is the same as that of the original one. The names 
proposed here are in the orders Palaeodictyoptera, Odonata, Dip- 
tera, Hymenoptera, Coleoptera, and Lepidoptera. 
Order Palaeodictyoptera 
Family uncertain 
Boltonocosta, nomen novum pro Orthocosta Bolton, 1912, p. 
310, non Fritsch, 1879, p. 28. Type-species: Orthocosta 
splendens Bolton, 1912, original designation, becomes Bol- 
tonocosta splendens (Bolton), new combination. The genus 
is known only from the Upper Carboniferous of England. 
Eurydictyella, nomen novum pro Eurydictya Guthorl, 1934, 
p. 49, non Ulrich, 1889, p. 301. Type-species: Eurydictya
