I liave discussed my identification oE tlie type specic-s 

 P. abdominafe, Gu6\'., under that species. Asiiniead ((Jan. 

 Ent. p. 32(5, IbDO) evidently differs from tliese conclusions, 

 and uses Par(iiiyss)n (or several North- American species 

 which are true Nyssoiiinaj; but I consider he is completely 

 mistaken in his identification of the genus. He also asso- 

 ciates Ilel'wryctes with the Nyssoninas, but the incision of the 

 mandibles and the presence of only one spur to the inter- 

 mediate tibial seem to me to render this association impossible. 

 Probably he was only acquainted with II. melanopyrus, 

 which he gives as the type by description. Associated with 

 the Pisonina? together with Sphodrotes he places his genus 

 PseudohcUoryctes (type P. fo.vii, Ashm.), which he founds 

 for a species apparently only distinguished from true Helio- 

 rycles by the absence of the coxal spine. This spine is also 

 missing in Paranysson heiioryctoides, Turn., which I certainly 

 look on as congeneric with other Paranysson. 



Key to the Species of Paranysson. 



1. "Wings liy.'dine, verj' slightly clouded at the 



ajiex ; posterior ocelli very near to the 

 eyes, fully three times as far from each 



other as from the eyes. (Asiatic.) .... P. assimilis, Bingh. 

 Wings fuscous or fusco-violaceous ; poste- 

 rior ocelli never more than twice as far 

 from each other as from the eyes, usually 

 much less. (iVfrican.) 2. 



2. Posterior ocelli nearly twice as far from 



each other as from the eyes ; spur of 



hind coxa? reduced to a tubercle P. heUurydoides, Turn. 



Posterior ocelli very little, if at all, further 

 from each other than from the eyes; 

 spur of hind cox<*B well developed .... 3. 



3. Spur (jf the hind coxa? originating before the 



inner angle, near the middle of the inner 



margin 4. 



Spur of the hind coxse apical, originating 

 close to the inner angle 5. 



4. Apical joint of the flagellum no longer than 



tlie penultimate ; median segment striate- 



reticulate P. melonopyrns, Sm. 



Apical joint of the flagellum distinctly longer 



than the penultimate ; median segment 



longiludiually striated P. oscari, Turn. 



•5. Median segment longitudinally striated ; 



pronotum ferruginous P. ahdoyninale, Gu^r. 



Median segment reticulate or striate-reticu- 



late ; pronotum black P. (putdridtntatuSjQ&m.
