SOME NEW PARASITIC HYMENOPTERA. 



BY H. L. VIERECK, PHILADELPHIA. 



Hammaniella relativa, n. sp. — Face and dorsum subopaque. 

 punctured, front opaque, the pleura more shining, longitudinal raised 

 line on metapleura distinct, terminated abruptly, the mesothorax not 

 appearing sharply truncate. The longitudinal medial lines on meta- 

 notum converging. 



% . — Length 14 mm. Clypeus with a few punctures, somewhat 

 shining, transversely impressed, anteriorly though not strongly. Face 

 closely punctured, front opaque. Cheeks impunctate on the eye margin, 

 otherwise with distinct, small, separated punctures, shining malar space 

 punctured, opaque. Dorsulum almost opaque, the punctures tolerably 

 small, closely arranged. The scutellum more strongly punctured. 

 Mesopleura shining, with well separated, to smaller closer punctures. 

 Metanotum with converging, crude, longitudinal medial carinas becoming 

 obsolete before the apical margin, transverse carina strong. Metapleura 

 separated from the metanotum by a distinct raised line, which stands out 

 prominently, being margined on each side by a more or less distinct 

 channel. Wings subhyaline, with a dullish cast. Areolet imperfectly 

 trapezoidal in form, the petiole shorter than any of its sides, one-half of 

 the curved and longest side of the areolet, one-half of the second 

 recurrent nervure and a short distance of cubito-discoidal nervure, 

 hyaline; stigma and nervures almost uniformly light brown, base of the 

 wings yellow. First dorsal segment strongly punctured, the spiracles 

 distinctly produced, the succeeding dorsal segments becoming less and 

 less punctured, to almost smooth. 



Black : face, clypeus and mandibles excepting apex, four anterior 

 femora, tibiae and tarsi, a pointed mark on anterior part of the dorsum, 

 two dots on scutellum, extreme base and apex of posterior femora and 

 the posterior tibiae excepting apex, ochraceous. Tegulas, one spot aside 

 and below them, coxae and trochanters of four anterior legs, part of 

 posterior coxa? and trochanters, yellow. On the posterior legs the 

 greater part of femora, apex of tibiae and all of tarsi are more or less dark 

 brown. Apex of first dorsal segment somewhat claret-brown, the second, 

 third, fourth and greater part of fifth mostly ferruginous. 



Type : Coll. Am. Ent. Soc, Phila.
