^ 9. Lenjrtli, 1 to 1.2 '". Polislie<l black, iinpunctured. Head 

 transverse, as wide as the thorax across jioni wing to wing, the vertex 

 posteriorly ))olished, without trace of aciculations. Antenna' 10 Jointed, 

 blaek, the flagelluin subdavate; pedicel pale at tip, as long as the 

 tirst two funiclar joints together; first funiclar joinrminut<»; the second, 

 third, and fourth nearly equal; club i.jointed, very slightly thicker than 

 the funicle, all the joints distinctly longer than wide, the first the short- 

 est, the last the longest. Thorax long ovrte, polished, itnpunctur«*d, 

 the parapsi(hil furrows very faint; scutelluni flattened, or subconvex, 

 .sei)arated from the mesonotiim by a very delicate, transverse, impresse<l 

 line ; nieso])leura smooth ; metapleura strongly sericeous. Tegula' black. 

 Wings hyaline, iridescent, pubescent and fringed. Legs brown-black, 

 the trochanters, tip of anterior tibia', and all the tarsi i)aler. Abdomen 

 oblong ovate, i)o]ished, very slightly longer than the thorax, the petiole 

 coarsely grooved, the second segment with some longitudinal strije at 

 base. 



The male is smaller, the abdomen oval, shorter than the thorax, while 

 the autenme have a 0-jointed, slightly pedicellate club. The first 

 funiclar joint is very minute, nmnded, closely connected with the sec- 

 ond, the second a little curved and thickened, truncate at tip; the first 

 club joiut is the smallest, the others Very gradually increase to the last, 

 oblong-oval in shape, the last being larger and thicker, fusiform, and

Specimens in National Museum. 



Described from $ aud 9 specimens, reared June 14, 18H4, by Mr. F. 

 M. Webster, from lajjlosis tritici, 



I had previously identified a syieciesof Poly</nofi(s as riatyf/aster error 

 Fitch, but a more careful examination of Fitch's figure and description 

 satisfies me now that I was mistaken, aud that the species described 

 here is really his P. error. 



The identification by Dr. Fitch of the fragments of an insect sent to 

 him by Mr. Herrick and reared from an Hemiptenms egg (Nabis), as 

 his PIdttfgaster error, was certainly erroneous, since it was undf)ubtedly 

 nothing but a species of Telenoinus, as Mr, L. O. Howard has already 

 pointed out.
