of the pronotum and in having the disk of wings ochre-yellow instead 

 of deep orange-red. The fenestrate area of the wings in the present 

 species is a little more regularly veined than in miniatus. 



Vertex between the eyes rounded, longitudinally carinate, the 

 fastigium aboul as long as wide, the antero-lateral carina? straight, 

 meeting in front at an acute angle; lateral foveolae triangular, small, 

 basal, barely visible from above. Fronted costa prominent above, 

 viewed in profile roundly produced between the antenna-, the sides a 

 little narrowed between the ocellus and antenna-, but evenly divergent 

 below that point, reaching the base of the clypeus, sulcate throughout; 

 facial or lateral carina- broadly arcuate, their lower ends a little farther 

 apart than the upper. Occiput and vertex gently ascending. Eyes 

 fairly prominent, their length equal to the anterior margin of the 

 cheeks. Pronotum only gently rugulose, with well-defined lateral 

 carina-, which are more widely separated on the hind than on theanterior 

 lobe; and with the lobes subequal in length. Tegmina and wings 

 completely developed, about reaching the apex of the hind femora, 

 the former coriaceous, moderately broad, and with the costal field 

 well developed, broadly rounded and supplied on the basal one-fourih 

 with a small lobe, the apex obliquely truncate. Wings with a regularly 

 fenestrate costal held. Hind femora rather robust, much coarser 

 than in the same sex of miniatus; tibiae also heavier than in the allied 

 species. 



General color of insect above brunneo-ferruginous; face uniformly 

 pale greenish yellow; venter, except pale median line, pectus, and 

 lower margin of middle and hind femora together with the coxae black, 

 tibiae also black. Wings on disk and basally dull chrome-yellow, t he- 

 apex and a narrow r border towards hind angle infuscated. Antenna-, 

 except the apex which is black, brunneo-testaceous. 



Length of body, o 71 , 22.5 mm., of pronotum, 5.25 mm., of tegmina, 

 18 mm., of hind femora, 16 mm.
