f/ Ophion AREOLATUS, Sp. nov. 



Long. 15 mm. 



The orbits broadly and the vertex pale lemon-yellow; 

 the face and occiput ferruginous, suffused with yellow. 

 The face and clypeus finely, but distinctly, punctured ; 

 the clypeus separated by a furrow from the face, and with 

 a deep oblique furrow at the sides. Mandibles smooth, 

 and yellow at the base ; the middle punctured ; the teeth 

 black. Thorax with the sides and scutellum of a distinct 

 yellow hue; the furrows bordering the middle lobe of the 

 mesonotum at the base wide, deep, distinct. Scutellum 

 smooth; the sides not carinate; the postscutellum dis- 

 tinctly carinate at the base ; its apex with an oblique 

 slope; its sides oblique, becoming wider towards the 

 apex. The depression at the base of the median segment 

 wide, deep, semicircular; in front of this is a transverse 

 keel, from which run two stouter keels to the apex; from 

 the middle of these runs a stout, curved keel to the middle 

 of the base of the petiole; there being inside this an 

 oblique keel; the whole forming, on the apex of the 

 segment, a central and two lateral arese. Pleurae shining, 

 impunctate; the depression below the tubercles wide and 

 deep ; from its apex runs, obliquely to the hinder coxae, a 

 distinct furrow, widest and deepest at the apical half 

 Wings clear hyaline ; the stigma rufo-fulvous ; the nervures 

 black ; the transverse median nervure is received on the 

 inner side of the transverse basal ; the second recurrent 

 nervure is received distinctly in front of the apex of the 

 basal abscissa of the radius; the apex of the cubital 

 cellule being thus longer on the lower than on the uppeir 

 side. 



A distinct species. Easily known, inter alia, from O. 

 fuscomaculatus, by the areolated apex of the median 

 segment.
