GOEYTES. 79 



broadly convex in the middle ; the apex almost transverse, depressed, and with a wide 

 and distinct margin ; labrum rounded, and fringed with long golden hair. The inner 

 orbits of the eyes and a broad irregular stripe across the middle of the clypeus are 

 yellow. The front and vertex with short, dull fulvous down and long fuscous hair ; the 

 clypeus, cheeks, and labrum with a long silvery, inclining to golden, pubescence. 

 Thorax shining, the mesonotum finely shagreened, shortly pilose; median segment 

 covered with long fuscous hair ; pleura? and sternum with a dull fulvous pubescence ; 

 the furrow at the base of the scutellum coarsely foveolate ; the edge of the pronotum, 

 the tubercles, a small spot behind them, a line on the hinder edge of the scutellum, and 

 a small mark towards the side of the median segment, yellow ; area on the base of the 

 median segment clearly defined ; the furrows deep, wide, and indistinctly crenulated ; 

 the two oblique furrows on the metapleura? wide and deep ; mesopleural keel distinct. 

 Petiole smooth, impunctate, shining, gradually but not much thickened towards the 

 apex, and clearly defined from the second segment ; second segment gradually narrowed 

 from the base to the apex, the extreme apex not being, or scarcely, narrowed, shagreened, 

 opaque ; the apex of all the segments bordered with yellow. Legs covered with white 

 pubescence ; the tibia? yellow in front, moderately spinose ; fore tarsi with the hairs 

 long but not numerous, the hairs (as well as those on the other tarsi) pale fulvous. 

 The second cubital cellule at the top is less than half the length of the third, and hardly 

 the length of the space bounded by the two recurrent nervures. 



The male has the clypeus entirely black ; the antennal joints thicker and those at the 

 base of the flagellum shorter, the third joint shorter than the first; the metanotum 

 yellow ; the yellow marks on the median segment larger ; the cloud in front of the 

 wings lighter in tint.

Antenna? shorter than the thorax, stout, thickened towards the apex, the third joint 

 a little longer than the fourth, the basal joint distinctly longer than the third. Eyes 

 converging beneath. Head alutaceous, densely covered with fuscous pubescence ; the 

 cheeks and clypeus with silvery hair ; a fine furrow runs down from the ocelli to the 

 antenna? ; clypeus broadly convex, projecting at the apex. Thorax opaque and aluta- 

 ceous above, densely covered with short fuscous pubescence, the median segment more 

 closely and with a longer golden pubescence at the base ; the pleura? and apex of the 

 median segment more shining, impunctate ; the basal part of the middle furrow on the 

 median segment narrow, and interrupted before reaching the wide and deeper oblique
