1 1 6. Copiocera formosa sp. nov. 



This is a very beautiful species, having the general appearance of 

 lepida, prasina, and boUviana, but differs from all of them in several 

 respects other than in coloration. 



Moderately slender and longer-winged than usual. Head, pro- 

 notum, pleura, outer face of the hind femora and most of the inter- 

 mediate portion and the apex of the anterior femora, together with 

 the front tibise bright olive-green; inner face and lower sulcus of the 

 hind femora bright blood-red. Greater portion of the dorsal sclerites 

 of the abdomen likewise of this color, the extreme edges alone nar- 

 rowly bordered with black. Venter flavous, tinged lightly with rose. 

 Anterior and lower margins of the pronotum, together with the carinas 

 bordering the insertion of the legs, narrowly white, or pale citron- 

 yellow; the anterior edge of the pronotum of the same color, followed 

 by a wider band or collar of deep black. Hind tibiae bright red, some- 

 what darkened exteriorly, the spines black. Antennae black, without 

 the usual pallid apical joints. Apex of the hind femora having the 

 genicular area mostly black, varied above with a rather large triangu- 

 lar, and at the sides a small rounded patch of yellow, also with a 

 pregenicular annulus of the same color. Coxae of all the legs and basal 

 half of the anterior pair strongly tinged with reddish purple. 



Vertex between the eyes a little wider than the diameter of the 

 basal antennal joint, the fastigium of the vertex a little elongate, 

 rather widely and deeply sulcate, this sulcation somewhat continuous 

 with that of the frontal costa; the latter broadly, rather deeply and 

 roundly, sulcate from its start to the transverse facial depression, 

 beyond which it quickly fades away; the lateral walls sharp; pro- 

 notum short, its surface coarsely and closely punctulate, the trans- 

 verse sulci straight, fairly deeply impressed; anterior and posterior 

 margins of the disc rounded, the median carina only present on the 

 posterior lobe. Tegmina of normal width, rather elongate and with 

 the veinlets few; this last mentioned feature is especially noticeable 

 on the dorsal and costal fields, but is also apparent even on the disc, 

 where there is a well-defined intercalary vein. Anterior and middle 

 legs small and very slender, the femora scarcely at all enlarged or 

 inflated; the posterior femora also very slender; hind tibiae few- 

 spined externally, on one leg two- and on the other three-spined, and 

 the spines located apically; internally provided with the normal nine 

 spines. Apex of the male abdomen of the usual form, the cerci long.
