412 HTMENOPTEEA. 



7. Toxoneuron croceum. (Tab. xvii. fig. 8.) 



Pallide flavum, macula magna metanoti abdominisque dorso ex parte nigris ; alis hyalinis, fascia substigmatali 



fumata, stigmate nigro. 

 Long. 5| millim. 



Hah. Panama, Volcan de Chiriqui 4000 to 6000 feet {Champion). 



Head very finely and closely punctured, the clypeus aciculated ; covered with a sparse 

 whitish pubescence ; face bluntly keeled ; clypeus rounded ; tips of the mandibles, and 

 the spot covering the ocelli, black ; a V-shaped, deep, furrow below the ocelli. Thorax 

 closely and finely punctured, more strongly so than the head ; the pleural sutures strongly 

 striolated ; the space on either side of the scutellum, and the metanotal suture, strongly 

 striolated, black. Metanotum with a line on each side, and the apex broadly, black ; 

 the apex with an oblique slope ; the sides obscurely striated. Abdomen longitudinally 

 striated ; a broad mark on either side of the first segment, a somewhat triangular mark 

 on either side of the second (the broad end at the apex), and the greater part of the 

 third segment, black ; the extreme apex more shining, and not striated like the rest of 

 the surface. Legs pale lemon-yellow ; the coxae finely punctured. Wings : the alar 

 nervures obscure testaceous ; the second cubital cellule narrowed towards the apex, the 

 part of the cubitus bounding it distinctly curved ; the recurrent nervure received about 

 half the length of the first abscissa of the radius in front of the first transverse cubital 

 nervure ; the transverse discoidal nervure a slightly shorter distance in front of the 

 transverse basal; the first discoidal cellule nearly One half longer than the second 

 cubital cellule ; the first abscissa of the radius nearly equal in length to the second, and 

 not half the length of the second abscissa of the cubitus. 



OLIXON. 



Antenna? 13-jointed ; the joints elongated, those of the flagellum of nearly equal thickness ; the third joint the 

 longest. Head elongated; the face transverse, projecting broadly; clypeus broadly transverse; eyes 

 placed well up, reaching to the top (and not below the insertion of the antennae) ; ocelli absent ; occiput 

 margined, transverse. Prothorax large, longer than broad, bulging out laterally in front ; metathorax 

 toothed laterally ; scutellum not denned from the scutum. Abdomen subsessile ; petiole broader than 

 long, becoming gradually broader towards the apex, its base margined ; the second and third segments 

 more than twice the length of the first ; the suturiform articulation obsolete ; the fourth segment longer 

 than the petiole ; the remaining segments becoming gradually shorter. Ovipositor short, exserted. 

 Anterior coxae enlarged, the femora short and thick ; tibiae shorter than the femora, and about half the 

 length of the tarsi ; hind tarsi more than twice the length of the tibiae, slender ; patellae of the apical 

 tarsal joints large, acute ; tibial spurs stout, reaching nearly to the middle of the metatarsus. Wings 

 abbreviated, reaching a little beyond the apex of the petiole ; without nervures. 



I am unable to point out the natural position of this curious genus. The elongated 

 fore legs give it the look of a Bethylid, to which, indeed, it bears a general resemblance; 

 but I feel inclined to regard it as a true Braconid.
