yellow beneath. Ovipositor rather long; apical valves occupying half 

 the total length, very finely denticulated. 



Legs yellow. Anterior tibiae perforated with two oval tympana. 



Elytra extending to the apex of abdomen, yellow shining with the 

 wide brown band which extends on the whole length, with veins widely 

 separated and somewhat projecting; dorsal field with four diverging 

 veins, the internal rather joining the 2d ; transverse veinlets very few, 

 forming a few irregular, large cells; lateral field with four veins, one 

 of which is incomplete. Wings yellowish, caudate. 



Length of body 4.2 mm.; length with wings 8 mm.; posterior femur 

 3.5 mm.; elytra 3 mm.; ovipositor 1.6 mm. 



Remarks: This species presents a rather irregular elytral venation 

 as in the species of the nitida gi'oup ; the coloration is characteristic. 

 The shape of the eyes and palpi is somewhat cyrtoxiphoid.

Figure 4,d 



Holotype: Male; Chanchamayo, Department of Junin, Peril,
