Color; straw j’ello'w; borders of the frontal carinae with short exten- 
sion upon vertex, a band at base of abdomen, a lateral basal spot on 
segments one to three and borders of the ovipositor, tibial spines, teeth of 
tibial spur, spines and claws of tarsi, black. Abdomen of male tinged with 
fulvus, bases of tergal segments sometimes infuscated. 
Genitalia. Female plates short, rounded at apex. Male hooks 
incurved nearly touching; style, long, slender, compressed. 
Described from twenty specimens, fourteen females, six 
males, collected at Cameron, La., by Prof. J. S. Mine in latter 
part of August, 1903. 
This species shows some striking resemblance to Kelisia, but 
aside from the characters which seem to require a separate genus 
it has well marked characters separating it from any species in 
that genus.
