ARADOPHAGUS Aslnn., j^en. iiov. 



Head oblong, very Hat, attached to the thorax hij^h up on the occiput, 

 the space between the eyes very Avide. Ocelli 3, subtriangularly ar- 

 ranged, the lateral far from the eye. Eyes oblong-oval, bare. 



Antenn.'e inserted at the mouth, subclavate, 12-jointed in both sexes; 

 the scape very long, cylindrical; the pedicel long, one-third hmger 

 than the first flagellar joint, the following joints shorter but stouter, 

 subequal. 



Maxillary and labial pali)i very short, inconspicuous, 2-jointed. 



Mandibles small, bifid. 



Thorax ovoid, very flat, the prothorax not at all developed or visible 

 from above; mesonotum smooth, without furrows, rounded before; 

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

 tip; metathorax short, with delicate lateral keels. 



Front wings fringed as in CerocephaJ((, the submarginal vein reach- 

 ing the costa before attaining half the length of flie wing, the marginal 

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

 is well developed. 



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

 the largest, about twice 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 characfers is quite distinct 

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

 strongly, aflinities with the Ceraphronltia' and was originally placed 

 therein my collection ; it also resembles a " Spalaiigiid," and caused 

 me, at one time, to contemplate removing the HpaUingliuw from the 

 (Jlialcidid(v to the ProctoirijpUJ(v. 



Aradophagiis fasciatus, sji. ikiv. 

 {I'l. VII, Fi.u. !», 9.) 



i 9 . Length, 1.5""". Iloney-yellow, smooth, polished, impunctured. 

 Scape, i^edicel, and basal half of first funiclar joint pale or whitish, the 

 rest of the antenna^, brown-black. Front wings fuscous, the base, a 

 transverse band at the middle, and the apical margin white; hind wings 

 hyaline. Abdominal sutures nairowly banded witli fuscous. 



Habitat. — Jacksonville, Fla. 



Types in National Museum and coll. Aslnneail. 



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

 1887, under live oak bark badly infested with Br((chi/rJn/)ichufi (/noiKhUus 

 Say and Pityophthorus qucrcipcrda Swz., the old e^^y^ masses of the Ara- 

 did being (piite i>leutiful. The single specimen in the National Mu- 

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

 \t from PifyophtJionis consimili.s Lee, together with scA'cral Oero('ei)h- 

 ahe. I believe its habits Avill prove identical with other Scelionids, 

 and it will be found to be a parasite in the eggs of the Arudidiv.
