be left for later treatment. The genot>pc is shaped like dolicho- 

 gaster and the generic differential may hinge on the greatly elongated 

 abdomen, if the club of Sympicsis is not truly 3-jointed and the 

 males do not differ genericalK . It will do no harm for the present 

 to let them stanH but if there is no true and real difference but only 

 an arbitrary and dermal one. the two must be combined. Here 

 are Australian, North American and Indian species which, super- 

 ficially, are identical. 



Pleurotropis longus, new species. 



Female — Length 2.7.5 mm. 



Characterized by the long abdomen which is depressed and 

 conical, distinctly longer than the head and thorax combined; 

 like perdubius but the abdomen is more slender and somewhat 

 longer, its segment 2 is glabrous and somewhat longer, the tibiae 

 arc black to tips, funicle 1 is more slender, thrice longer than wide, 

 2, twice longer than wide. Otherwise the same. 



Described from one female reared in connection with Isosoma, 

 Lafayette, Indiana, (W. J. Phillips).

 on a tag, antenna^ and a pair of wings on a slide. 



Aphidencyrtus inquisitor (Howard). 



IVIany females from Myzus persica on peppers, Norfolk, 

 X'irginia, (D. E. Fink), October, 1915. 



Asaphes americana Girault. 



Norfolk, Virginia, Septeml;er 3, 1915, from Aphis nimiris 

 (D. E. Fink). The caudal coxa^ may be suffused with yellowish. 

 Ormyrus unimaculatipennis, new species. 



Note — In Ormyrus the parapsidal furrows are distinct, that 

 is, easily seen but they are delicate, not deep. It is an error to 

 say there are no parapsides. Howe\er. these furrows are some- 

 times subobsolete. 



Female — Length- 2.85 mm. 



Dark metallic green, the scape (except a little at apex above) 

 and legs (except the coxie), reddish brown, the caudal tibiae black, 

 the tarsi white. Fore wings hyaline but with a large, distinct, 

 rectangular (a little longer than wide) fuscous spot under a little 

 less than the distal half of the marginal vein and which touches 

 the apex of the stigmal and extends to the middle of the wing;
