HYMENOPTEROUS FAMILY STEPHANID.B. 747 



In the (4) Stett. ent. Zeit. 1906, p. 301, the name is altered to 

 ParastephanelliijS, Parastephanus being preoccupied by Haeckel 

 for Protozoa. The apparently constant difference between the 

 relativ^e sizes of the discoidal and cubital cells and of the stigma 

 in the above-named two regions led to a further subdivision, 

 removing the Neotropical species to a new subgenus, Hemiste- 

 phanus. 



Parastephanell'us, confined to the Indo-Australian Region, has 

 the discoidal cell petiolate and only about one-fourth as large as 

 the cubital cell; the radius does not extend to the margin of the 

 fore wing, and, as a rule, the stigma is short and broad. The 

 sheaths of the terebra are black, except in No. 6, in Avhich they 

 are rufescent.
