TELICONES. 387 



YELICONES. 



Head transverse, slightly tumid in front, excavated above the antennae. Eyes large, oblong, reaching nearly 

 to the base of the clypeus. Antennae filiform, rather stout, the third joint longer than the fourth. Occiput 

 scarcely margined. Metathorax with one or two central and two lateral keels on either side. Abdomen 

 flat, sessile, the basal two segments keeled down the centre, striated ; suturiform articulation distinct, 

 striated ; ovipositor scarcely projecting. Legs short, thick, the tarsi shorter than the tibiae ; fore tarsi with 

 the basal joint scarcely twice the length of the second, the second, third, and fourth joints not broader than 

 long, the apical joint much enlarged and as long as the other joints united ; hind tarsi with the basal joint 

 as long as the other four joints united, the apical joint as long as the preceding three united ; claws pecti- 

 nate. Wings with three cubital cellules ; the second cubital cellule small, scarcely or not much more than 

 twice the length of the first, narrowed at the top ; second humeral cellule shorter than the first diseoidal 

 cellule ; the recurrent nervure received considerably in front of the first transverse eubital nervure. 



If the occiput be said to be not margined (and the margin is so indistinct that it 

 might be thus described), this genus would fall into Forster's division " Exothecides ; " 

 if margined, it would fall into the " Bhogadides." I am inclined to regard it as allied 

 to the latter. The peculiar structure of the tarsi separates it from any of the known 

 genera of either group. The ovipositor is scarcely exserted.

Antennae stout, densely microscopically pilose ; the third joint longer than the fourth. 

 Head shining, the vertex sparsely covered with shallow, minute punctures, and the face 

 with pale hair ; a large shining depression over each antenna, marked with some oblique 

 keels ; from the ocelli a stout keel runs down the centre of the face to the clypeus ; face 

 strongly obliquely striolated ; eyes margined ; mandibles pale luteous, the tips piceous. 

 Thorax, except the sides of the pronotum behind, densely covered with a grey pubescence. 

 Pronotum in front and beneath and the mesothorax closely but not strongly punctured ; 

 at the apex of the mesonotum, in the centre, close to the scutellum, is a rather long and 

 narrow space, this space bordered on either side and marked with stout transverse keels ; 

 the sides of the prothorax also bear keels, and the lateral sutures of the meso- and 

 metathorax are crenulated. Metathorax coarsely reticulated ; in its centre are two keels, 

 which are near each other a little past the middle and separate again near the apex 

 (thus forming an elongated keel at the base and another at the apex) ; on either side also 

 there are keels. Abdomen a little longer than the thorax, flat, rounded at the apex ; 

 the basal segments closely longitudinally striated, the others longitudinally punctured ; 

 the first and second segments have a keel down the centre, the first also with a keel down 

 the sides ; densely covered with pale hair. Wings smoky, with a bluish tinge ; the 

 recurrent nervure received a little beyond the middle of the first cubital cellule ; the 

 second cubital cellule small, about half the length of the first, narrowed at the top,
