Genus 5.—Psalis, Serv. 
This genus only differs from Anisolahis and Euborellia 
in having fully developed organs of flight. Carcinophora, 
Scudder, must fall, the only real difference from typical 
Psalis being the abbreviation of the wings alone; as the 
character is insufficient to justify specific rank, it cannot 
support a genus. 
I now include it in the following sixteen species:— 
1. Pronotum parallelum ; species ameri- 
canae. 
2. Elytra abbreviata, scutello saepius 
j'atenti; elytra maculata .... 
2.2. Elytra perfecte explicata.

elytra ad humeros maculata. 
5. Corpus glabrum ; abdomen seg- 
mentis 6-9 lateribus acutis . 
5.5. Corpus pilosum ; abdomen 
segmentis 6-9 baud acutis 
4.4. Statura majore ; (18-25 mm.)
