Genus 24. Anaclinia, Winn, 
Costal vein extending beyond the tip of the second longitudinal 
vein. Auxiliary vein large, ending in the costa a little before the 
middle of the anterior l)order, united to the first longitudinal 
vein by the sub-costal cross-vein which is situated before the 
middle. Basal portion of the second longitudinal vein and the 
marginal cross-vein equally long. Anterior branch of the third 
longitudinal vein incomi)lete, not connected with the third longi- 
tudinal vein. Inner marginal cell short, extending a little beyond 
the root of the third longitudinal vein. Base of the second 
posterior cell situated beyond the root of the second longitudinal 
vein. Surface of the wing distinctly microscopically pubescent. 
Abdomen with seven segments. 
Genus 25. Boletina, Staeger. 
Costal vein extending beyond the tip of the second longitudinal 
vein. Auxiliary vein very large, terminating in the costa at the 
middle or a little before the middle of the anterior margin, and

Sub-costal cross-vein rarely missing (in the European species B. 
dispar). Basal portion of the second longitudinal vein to 
twice the length of the marginal cross-vein. Inner marginal cell 
short, its apex lying before the base of the second sub-marginal 
cell. Fork of the third longitudinal vein long, its petiole short. 
Base of the second posterior cell situated before the base of the 
second sub-marginal cell. Surface of the wing microscopically 
pubescent. Abdomen with seven segments. 
Genus 26. Gnoriste, Meig. 
Costal vein extending beyond the tip of the second longitudinal 
vein. Auxiliary vein and sub-costal cross-vein as in Boletina. 
Inner marginal cell long, its apex situated over the base of the 
second sub-marginal cell. Fork of the third longitudinal vein long, 
its petiole very short. Base of the second postei’ior cell before the
