OPHION— NOTOTEACHYS. 295 



three obscure fuscous stripes, the sutures very shallow ; metanotum with two distinct 

 transverse keels, united in the centre by two longitudinal ones, which form a longish 

 area ; from the apical transverse keel run some not very clearly defined keels to the apex 

 (except the central two, which form an area, narrower towards the apex, in front of the 

 above-mentioned area between the two transverse keels). Petiole inclining to yellowish, 

 indistinctly keeled; postpetiole thicker than, and clearly defined from, the petiole, 

 luteous, and finely and closely punctured. The other segments are densely pilose, the 

 apical one more darkly coloured. Smaller than 0. flavo-orbitalis ; the head and thorax 

 almost entirely yellow; the third joint of the antennae longer; the first abdominal seg- 

 ment longer and narrower ; the postpetiole longer in proportion to the petiole ; the 

 second segment contracted before the middle (in addition to the contraction at the base) ; 

 the first discoidal cellule distinctly angled in the middle above, the bulla received quite 

 close to the middle, the projecting branch reaching nearly halfway across. 



b. Inner discoidal cellule not angled ; the recurrent nervure not emitting a branch ; 



stigma black.

Luteus, orbitis thoraceque flavis ; antennis nigris ; alis hyalinis, stigmate nervisque nigris. 3 . 

 Long. 23 millim. 



Edb. Panama, Volcan de Chiriqui 2000 to 3000 feet (Champion). 



Head strongly punctured ; a longish, clearly defined tubercle below the antennae ; 

 antennal regions projecting, separated from the eyes by an oblique depression, which 

 extends near to the inner side of each antenna ; tips of the mandibles piceous-black. 

 Antennae longer than the body, densely pilose ; third joint longer than the fourth and 

 fifth together; the apical joints brownish. Thorax pilose, shining, impunctate ; meta- 

 notum without keels. First discoidal cellule rounded at the upper inner corner, and 

 without any branch ; bulla received a little beyond the middle.
