ARADOPHAGUS Ashm.. ;>eii. nov. 



Hesid obloiij'. very tlat, attiiched ht tlici tlioiax lii^ifhnpou the occiput, 

 tlie space Ix'tweeii the eyes very wide. 0<relli 3, subtrian};iUarly ar- 

 ranj^ed, the Uiteral far from the eye. Eyes obh»ng-oval, bare. 



Anteniue inserted at the mouth, subclavate, lli-jointed iu both sexes; 

 the scape very hni^x, cyliinlru!al; the pedicel long, one-third l(m<>er 

 than the first fiajiellar Joint, the following joints shorter but stouter, 

 subequal. 



Maxillary an«l labial palj)i very short, inconspicuous, 2-Joint«>d. 



Mandibles small, bifid. 



Thorax ovoid, very flat, the ]>rothorax not at all developed or visible 

 from above; meson<»tum smooth, without furrows, rounded before; 

 scutellum short, semicircular, with a very delicate cross-line before the 

 tip; metathorax short, with delicate lateral keels. 



Front wings fringed as iu Cerocephala , the submarginal vein reach- 

 ing the costa before attaining half the length of the wing, the nmrginal 

 vein longer than the oblique stigmal vein, while the post-marginal vein 

 is well developed. 



Abdomen very flat, ovate, with a short petiole, the secoml segment 

 the largest, about twi<e the length of the first, the third and fourth 

 about equal, two-thirds the length of the second; ovipositor exserted. 

 Legs slender. 



This genus in its thoracic and antennal characters is quite distinct 

 from all others in the group, and requires no special comment. It shows, 

 strongly, aflinities with the Ccniphroniua- and was originally ])laced 

 therein my collection; it .also resembles a '' Spalangiid," an<l caused 

 nu', at one time, to contemplate removing the SpaUaigiimv fnmi the 

 Hhah-UlUUv t«> the ProctotrypUhv. 



Aradophagus fasciatus, sp. uov.

 Scape, pedicel, and basal half of first funiclar joint i)ale or whitish, the

Types in Xational Museum an«l coll. Ashmead. 



The two specimens in my collection were taken by myself in April, 

 1887, under live oak bark badly infested with BrachyrhynehuH fframdat us 

 Say and PityoplithoruH querciperda Swz., the old egg masses of the Ara- 

 did being <piite plentiful. The single si)ecimen in the National Mu- 

 seum was taken by Mr. E. A. Schwarz in Florida, whothinks he reared 

 it from Pityophtli(nvs consimilis Lee, together with several CerocepU- 

 ala*. I believe its habits will prove identical with other Scelionids, 

 and it will be fouud to be a parasite in the eggs of the Aradidiv.
