Lcdra (part) Walker 1851 List. 809-30. 



Stenocotis Stal. 1854 O. V. A. F. Xl, 254; and 185(3. op. c, 

 XIII, 67, (type siibvittata Stal.) 



Head short, flat, horizontal, anterior margin obtuse-angularl} 

 produced, acute, carinate, the keel forking on each side of the 

 middle and reuniting nearer the eyes, thus enclosing a short, nar- 

 row, suboval area in the middle of each anterolateral margin, in 

 which the ocelli are placed. Posterior margin angularly emar- 

 ginate, the middle of the pronotum anteriorly much anterior to 

 the apical margin of the eyes. Eyes oblique, reniform, longer 

 than wide, extending laterally farther than the pronotum. Ver- 

 tex longitudinally striate, pronotum transversely so, but anter- 

 iorly sublongitudinall)'. Scutellum transversely striate. Frons 

 slightly convex, antennal ridges not deep, lorae and clypeus elon- 

 gate. Pronotum about as long as wide, much longer than the 

 vertex medianly, flat in front, raised posteriorly, lateral margins 

 straight, subparallel, posterior margin obtusely emarginate. 

 Tegmina extending farther posteriorly than the abdomen in the 

 male, not so far in the female ; clavus with the usual veins and 

 also with some transverse veins connecting axillary with commis- 

 sure and one connecting anal with the suture near the apex, in 

 the corium, the medioradial forks near the base, the median be- 

 ing joined almost immediately to the cubital by a transverse vein. 

 There are 5 discoidals of which two are subbasal and 3 subapical. 

 There are a number (at least 10?) of apical cells, all much longer 

 than wide, in some species many of them forked and many divid- 

 ed transversely. Tibiae dilated. 



A number of species have been described by Stal and Walker, 

 but there are probably several synonyms among them, as the 

 sexes are apparently dissimilar. The specimens collected by 

 Koebele and Perkins seem to belong to S. plaiiiiiscitla Stal.

Nymph: In my own collection. I have 3 examples, from Vic- 

 toria, of nymphs that I doubtfully refer to the same species ; they 

 at least belong to this genus. The whole insect is very flat, the 

 head is enormously arched, the anterior margin of the vertex be- 

 ing roundly angular. Just above the eye, it is deeply emarginate,
