MR. 11. m'lACHLAN ok. NEW SPECIES ETC. OE NEUEOPXEBA. 255 



raesothorax ; middle costal veinlets black at their commencement on 



the margin, the first wholly black ; the commencement of the sectoFj 



and the four first veinlets between it and the radius, almost wholly 



black ; several veinlets below the commencement of the radius and the 



whole of the outer gradate series, and several in continuation between 



the branches of the cubitus, wholly black ; postcostal furcation and 



the veinlet beyond it black, the cellule between fuliginous; gradate 



series scarcely parallel; marginal veinlets simply forked; pterostig- 



matical veinlets numerous : posterior wings with all the veins and 



veinlets pale. Legs pale yellowish white, pubescent. Abdomen yellow, 



the apical half with black spots. 



This beautiful insect is very closely allied to C. varia, Sclineider, 



but differs especially in a somewhat different arrangement of the 



black veinlets, and in the fuliginous cellule at the end of the post- 



costa ; it is also larger.
