up into several genera, but 1 have followed Kohl, in treating 

 Aporus and Evagefhrs as sub-genera; we have fifteen 

 species recorded from this country ; Kohl, in 1884, records 

 483 known species, of which 133 are palfearctic; the genus 

 extends over nearly the whole world, and much requires 

 monographic treatment. Antenna; curled at the apex after 

 death, forehead and vertex impunctate, pronotum posteriorly 

 angularly or arcuately euiarginate, wings with two or three 

 submarginal cells ; abdomen in the c? with eight segments 

 exposed ventrally, the extreme central apex of the seventh 

 only visible, the eighth varying much in shape, and affording 

 good specific characters, the eighth dorsal valve is hidden 

 beneath the seventh, and bears two penicilli, which are 

 often visible beyond the apex of the seventh; in the ? tho 

 sixth segment is convex dorsally, and pointed at the apex ; 

 legs very long and slender, tibiaj in both sexes simple, not 

 serrate, more or less spinose.
