specimens from Old Point Comfort were found on the beach of 

 Chesapeake Bay swept ashore by the waves. 



A NEW SCELIONID FROM QUEENSLAND, AUSTRALIA, PARA- 

 SITIC ON ACRIDIID EGGS, WITH DIAGNOSIS OF AUSTRALIAN 

 SPECIES 1 : 



(Hymeiioptera; Proctotryooidea.) 

 BY A. A. GIRAULT. 



FAMILY SCELIONIDAE. 

 SUBFAMILY SCELIONINAE. 



Genus SCELIO Latreille. 



1. Scelio ovi, new species. 



Normal position. 



Female. Length, 4 mm. more or less. 



The same in all respects to Scelio australis Froggatt, but the 

 scape, pedicel, and sometimes the first funicle joint of the antenna 

 are reddish-brown like the legs instead of being black: also the 

 venation differs in that the stigmal vein of australis is somewhat 

 shorter, straight but at its extreme tip bent : this vein in ovi, how- 

 ever, is longer, its whole length slightly convexly curved, the 

 convexity distad; the blunted end of the vein in australis points 

 proximo-cauclad; in ovi, the extreme end of the vein has a slight 

 blunted appearance which is turned slightly distad. The wing 

 fumation also differs in that there is a distinct stigmal spot in 

 australis, round and covering the basal half of the stigmal vein 

 and the apex of the marginal, while in ovi the spot is elongate, 

 does not involve the marginal vein, though originating at the 

 base of the stigmal, but follows the latter on each side for a half, 

 two-thirds, or sometimes, its whole length; it is thus less clear 

 cut than in australis. The sculpture of both species is practi- 

 cally the same; ventrad, the proximal half of the second (first 

 body) segment of the abdomen is punctate; the striations of the 

 same segment dorsad are coarser than that of the following seg- 

 ments; the metathorax at the mesial region is sulcate, the sulci 

 with transverse divisions; laterad, in the dorsal aspect it is densely 

 punctate and covered with whitish pubescence. This refers to 

 both species. The antennae are 12-jointed. The coxa? are darker, 

 the mandibles bidentate, the teeth acute; the proximal funicle 

 joint is always suffused with brownish (ovi).
