sprinkled with black, becoming almost unicolorous black, on sides 

 of face the black sprinkliugs coalesce into larger 

 spots ; a large black spot on each side of meso- 

 notum ; tegmina greenish-browu, veins brown to 

 black, cells in places tilled up with reddish- 

 brown, the costal membrane hyaline, traversed 

 by simple or in places forked veins, which as well 

 as the costal margin itself are set with erect 

 gTeenish hairs, similar erect bristles are also 

 FitJ. 190. visible on the head ; wings black, thickly irregu- 



Fterygoma namta. larly reticulate ; legs spotted and striped with

" Luteous, spotted with black ; head transA'erse, anteriorly tri- 

 spinose, one obtuse point in front of each eye and one forming a 

 prolongation of the vertex ; tegmina anteriorly dilated, luteous or 

 ochraceous-yellow, with some small tubercles and short transverse 

 streaks black ; wings bruuneous ; body beneatii yellow variegated 

 with black ; legs flavescent ; the anterior margin of the tegmina 

 is spinose, it comprises a limbus outside the radius as broad as the 

 external flap of the wing, about half a line, transparent, vitriform, 

 or like an exceedingly fine plate of talc, furnished throughout w ith 

 oblique veins (parallel to each other) contrasting in colour and 

 substance with that of the limbus itself ; these veins when the 

 limbus is injured stand out like the teeth of a comb and give a 

 peculiar appearance to the insect ; the face is ascendiug, and is 

 divided from the base to the upper margin into three facettes 

 which form between them obtuse angles ; the median increases 

 from below upwards and reaches the vertex, and is divided by a 

 longitudinal ridge which descends from above and loses itself 

 towards the middle of the face ; the two interior facettes rise a 

 little higher than the median, but without converging above it, 

 they bend outwards and in an acute and prominent point above 

 the eyes ; vertex broader than long, concave, margins gently 

 raised, anterior bisinuate, posterior weakly emarginate ; median 

 lobe of pronotum broad, I'ounded." {8j)inoln.)
