CLADURA. 187 



Gen. XXVI. CLADVRA. 



Two submarginal cells (compare above, p. 34, tlie wing of C. indichd) ; 

 Jive posterior cells, the second petiolate ; discal cell closed ; prsefan^a arcu- 

 ated at its origin, which is very little anterior to the middle of the length 

 of the wing, but a considerable distance anterior to the tip of the auxiliary 

 vein (this distance being more than the breadth of the wing) ; subcostal 

 cross-vein a short distance from the tip of the auxiliarj vein ; seventh 

 longitudinal vein straight. Wings glabrous, except a short pubescence 

 along the veins in the apical portion of the wiug. Antennae 16-jointed. 

 Feet very long, pubescent : tibite without spurs at the tip ; tarsi with dis- 

 tinct empodia ; ungues smooth on the under side. The upper side of the 

 last abdominal segment is horny, convex, having a rounded excision 

 between two projecting points on its posterior margin (Tab. IV, fig. 2/, 

 forceps of C. Jlavoferrucjinea ; a, horny convexity ; b, excision) ; the forceps, 

 inserted under the convexity, is large, and consists of a long, cylindiical 

 basal joint and a horny branch upon it. Ovipositor with flattened, rather 

 broad valves. 



Rostrum and palpi short ; last joint of the latter stout ; front 

 moderately broad, very convex above the eyes ; the latter p-la- 

 brous, almost contiguous on the under side of the head. The 

 antennEe, if bent backwards, would reach the root of the wing's ; 

 joints of the flagellum subcylindrical, slightly incrassated at the 

 base ; verticils of moderate length. The wings are rather long 

 and comparatively narrow ; the veins, on their apical portion, 

 show a short, but distinct pubescence. The tip of the auxiliary 

 vein is somewhat beyond the inner end of the first submarginal 

 cell ; the latter is shorter than the second submarginal ; its petiole 

 is about equal in length to the interval between the subcostal and 

 marginal cross-veins ; the marginal cross-vein is in the middle 

 of the distance between the subcostal cross-vein and the tip of 

 the first longitudinal vein ; the prtefurca is strongly arcuated ; the 

 second submarginal and first posterior cells are of nearly equal 

 length ; in G. flavofen-uginea the second submarginal cell is 

 divided in two parts by a cross-vein in its middle ; this is not the 

 case with the other species, G. indivisa ; there are five posterior 

 cells, the petiole of the second posterior cell is much shorter than 

 this cell ; the pentagonal shape of the discal cell plainly shows 

 that it is the forking of the posterior branch of the fourth vein 

 which forms one of its sides; the great cross-vein is posterior to 

 the inner end of the discal cell ; the fifth, sixth, and seventh 

 longitudinal veins are almost straight. The presence of five
