Spilochalcis mesillae Cockeeell, Ann. Mag. Nat. Hist., ser. 6. vol. 19, p. 403, 

 1897. 



At JBrst glance this species seems quite distinct from all others, but 

 it is actually difficult to find infallible characters to separate the fe- 

 males from those of S. mariae (Riley). The female of this species 

 can best be recognized by the following characters : Body rather long 

 and narrow, transverse carinae of mesopraescutum strong, abdomen 

 acuminate, forewings with a browm spot around the stigmal vein, 

 metaf emur with a small inner tooth ; the longitudinal mesal stripe of 

 the mesonotum usually gradually widens anteriorly. In the male the 

 scape is strongly incised (fig. 8, s) , but the pedicel is cylindrical (fig. 9, 

 t) rather than triangular as in S. mariae (fig. 9, u) . 



Description. — Yellow or red with black markings; scrobe cavity, 

 usually two small spots on frons just ventrad of ocelli, mesal stripe 

 between posterior ocelli, occipital area, usually meson of pronotum, 

 usually a broad, longitudinal band extending from apex of mesoscutel- 

 lum to anterior margin of mesopraescutum, parapsidal furrows, some- 

 times broad spots at anteromesal angles of lobes of mesoscutum, pos- 

 terior margins of axillae, variable marks on mesopleuron, usually a 

 dorsal stripe on metacoxa of female, with both a dorsal and ventral 

 stripe in male, teeth of metafemur, usually a mesal stripe and areas 

 around spiracles on propodeum, and apex of ovipositor sheath, black ; 

 male often with a black stripe on f rontogenal suture ; wings brownish, 

 with a dark-brown spot surrounding stigmal vein. 



Female: 4.5-8.5 mm. Antennal scape exceeding, by one-fifth its 

 length, level of posterior ocellus, pedicel five-sixths and ring seg- 

 ment one-quarter length of segment 4, segment 4 slightly longer than
