AMERICAN HYMENOPTERA. 24o 



indistinctly punctured. Protborax and mesotliorax weakly, liut distinctly punc- 

 tured, the punctures clearly punctured, Metanotuni more opaque, sha^reened, 

 the apical slope almost transversely striated ; the areola horse-shoe shaped, as 

 ioug as wide, the apex slightly turned inwardly. Post-petiole somewhat strongly 

 closely longitudinally striated. Areolet five-angled, the recurrent nervure re- 

 ceived shortly beyond the middle; transverse median nervure received shortly 

 beyond the transverse basal; disco-cubital unbroken. Flagellum of antenna' 

 brownish below.

Wings fuscous, fasciate with yellow ; the transverse median nerv- 

 ure in hind wings broken below the middle ; areolet square, not 

 narrowed in front, angled below, the radial cellule small; disco- 

 cubital nervure unbroken. Metanotum rugosely punctured and 

 irregularly striated; there are two distinct transverse keels; the 

 spiracles are about three times longer than wide. Abdominal 

 petiole long, in 9 slightly, in ^ hardly dilated at the apex; curved. 

 Antennae in 9 short, dilated beyond the middle, the third joint as 

 long as the fourth ; in S slightly longer than it, longer and more 

 narrowed ; in l)oth sexes they are orange-yellow at the base, black 

 at the apex. Head lengthened in front ; malar space long; clypeus 

 separated ; labrum large ; temples wide, obliquely narrowed. Body 

 blue, immaculate. The median segment has an oblique slope. The 

 transverse median nervure is received almost behind the transverse 

 basal. 



Allied to Joppidium Walsh. Characteristic are the blue, strongly 

 punctured body, dark wings with wide fascia, strongly reticulated- 

 striated metanotum with two keels and steeply sloped apex, short 

 square areolet, short radial cellule and slender abdominal petiole. 

 The 9 of the latter has the antennae stouter at the apex than it is in 

 Joppidium, but in the males of the two genera there is not much 

 difference in length or thickness at the apex. Joppidium has the 

 apex of the metanotum rounded ; it bears only one keel, and the 

 transverse median nervure in the hind wings is broken at the mid- 

 dle. There is not much difference in the form of the an ten nit in 

 the two genera. In Prof Schmiedeknecht's arrangement (Oj)us.
