ORMENIS. — 55. 
ORMENIS. 
Ormenis, Stal, Bidrag till Rio Janeiro-Traktens Hem.-Fauna, ii. p. 68 (1858); Hemipt. Afr. iv. 
p. 236 (1866); Kongl. Svensk. Vet.-Ak. Hand]. Band 8, no. 1 (Hem. Fabr.), p. 109 (1869). 
The chief characteristics of this genus appear to be as follows :— Corium with two 
more or less distinct and regular rows of transverse venules towards the apex; ocelli 
distinct ; posterior tibie bispinose before the apex.” It seems to be very closely 
allied to Petrusa, Stal, from which it is said chiefly to differ in having the posterior 
tibie furnished with two spines before the apex, those in Petrusa being unispinose ; 
the latter character is not, I believe, always a reliable one, but as all our specimens, 
with one doubtful exception, appear to belong to Ormenis, we need not here discuss 
the matter further. 
The species differ very much in size; some of them are conspicuous insects, while 
others are very small and insignificant. 
1. Ormenis pulverulenta, (Tab. VII. figg. 18, 18 a.) 
Peciloptera pulverulenia, Guér. Icon. Régne Anim., Ins. p. 361°. 
Ormenis pulverulenta, Stal, Stett. ent. Zeit. 1864, p. 547. 
Hab. Mexico? (Mus. Vind. Ces.), Rinconada (Schaus), Vera Cruz (Mus. Vind. Cas.), 
‘Teapa in Tabasco (H. H. Smith), Bay of Campeachy !. 
This species looks very different when denuded of the violet or whitish-violet, waxy, 
scale-like covering which is usually present on the tegmina; the reticulation seems as 
if it might form a character, but this is found to vary in different specimens; the size, 
too, is very variable, the expanse of the wings ranging from 23-38 millim. 
Walker, List of Homopt. Ins. ii. p. 468, gives “‘ Ceylon” as the locality for P. pulve- 
rulenta, but he adds a query as to the species. 
A specimen from Rinconada is figured. 
2. Ormenis nigrolimbata, sp. n. (Tab. VII. figg. 19, 19 a.) 
Albida, tegminibus macul4é communi parva post medium nigra, et limbo perangusto ante hanc maculam 
deficiente fuscato; capite perbrevi, sat lato, truncato, oculis prominentibus, pronoto vertice fere longiort ; 
scutello szquilongo ac lato; tegminibus apicem versus paullo latioribus, apice fere recto late truncato ; 
alis lacteis ; corpore virescente. 
Entirely white above, with a distinct black common round spot on the tegmina; from this towards the apex 
proceeds a very narrow fuscous border, which is continued completely round the outer edge, though not so 
distinctly at the costal apical angle; the suture in front of the spot is not bordered ; head very short, with 
the eyes, which are prominent, as broad as the pronotum and about the same length; scutellum about as 
long as broad; tegmina with the sides nearly straight, wider at the apex, the apex broadly truncate; 
body greenish ; legs light, probably greenish in life. 
Long. 93 millim.; lat. ad hum, 23 millim. 
Hab. Panama, Bugaba (Champion). 
This is one of the most distinct of the smaller members of the genus.
