thickened ventral margin of the lateral lobes and the contiguous prosternal 

 lobe edged with wax yellow, median line of pronotum weakly lined with zinc 

 orange, stronger cephalad. Tegmina smoky fuscous with the venation of the 

 general color. Wings largely weakly washed with fuscous, the proximal sec- 

 tion of the disk washed with pale methyl blue. Prosternal process dull buck- 

 thorn brown, ventro-cephalic section of the mesopleura and cephalic section of 

 the mesosternum washed with madder brown. Abdomen apparently uniform 

 pale cendre green without the usual dark rings and yellow, orange or red areas 

 of other species of the genus. Cephalic and median limbs of the general color, 

 but the proximal half of the femora and also the same section of the tibiae, as 

 well as a wash on the tarsi, nopal red. Caudal femora of the general color 

 with the internal genicular arch and a portion of the lobe blackish; caudal 

 tibiae nopal red, the internal face of the proximal extremity washed with black- 

 ish, spines orange-buff tipped with black; caudal tarsi washed with nopal red. 

 Length of body, 41 mm.; length of pronotum, 6.9; greatest dorsal (caudal) 

 width of pronotum, 4.2; length of tegmen, 31.2; length of caudal fenuir, 18; 

 length of caudal tibia, 15. 



The type of this handsome species is unique.

Abuna, Rio Madeira. (Mann and Baker.) One female. 



This specimen has been compared with a Goyaz, Brazil, indi- 

 vidual of the species and it is not separable. It is, however, 

 somewhat larger and has the black areas on the sides of the abdo- 

 men smaller, less bar-like and of little vertical extent, while the 

 bluish is absent from the base of the wing. The latter condition 

 can be accounted for by the specimen having been in a liquid 

 preservative, which has destroyed or seriously injured other 

 features of the coloration. 



The species was recorded bj^ Gerstaecker from Olivenga, Bra- 

 zil and Pebas and Iquitos, Peru, in the upper Amazon basin.
