Ormenis quadripunctata (l*abr.). 
There are six specimens from Porto Rico which agree with 
the descriptions of this species. There is no subapical transverse 
line. 
Ormenis infuscata (Stal). 
There are two specimens from Vega Baja, P. R. (R. T. 
Cotton, 8, 4, 16, Acc. No. 518-16), which the writer considers 
to be this species, judging by descriptions. The subapical trans- 
verse line could be considered as present, as it is fairly well 
developed, the cross-veins being fairly regular. If we consider 
this as a line, then it would be an undescribed genus near to 
Acrophaea Mel. The frons is wider than long, and there are two 
spines on the hind tibiae. 
Ormenis marginata (Brunnich). 
This is made by Melichar into a monotypic genus Petrusina 
in which there are two transverse lines in apical area, but in 
the specimens from Porto Rico the cross-veins are somewhat 
irregular and obscure. 
Ormenis pseudomarginata sp. n. Plate XII, Figs. 7, a, b, c. 
Male. Length, 2.7 mm.; tegmen, 4 mm. 
Frons broader than long (1.3 to 1), median carina distinct on basal 
half, absent from apical half, lateral carinae only indicated at base, lat- 
eral margins carinate; no carinae on elypeus; vertex very short, mostly 
covered by pronotum; width of head equal to, or wider than, width of 
thorax, no carinae on mesonotum or only a slight indication at the base 
of median carina. Hind tibia with only one spine. Costal area distinet 
with transverse veins, and slightly granulate. Se very strong, simple to 
apex; R arising from M near its base and forking about one-third from 
base of tegmen; Mf level with Rf, Cuf slightly basad of former two; 
granulations over the base of R and M obscure their junction. Nodal line 
slightly arcuate and formed by some irregular cross-veins and a slight de- 
pressed line across tegmen from node to apex of clavus; apical line fairly 
even and distinct; claval vein forking near apex, clavus strongly granulate. 
Pronotum and mesonotum black or very dark fuscous brown, frons 
lighter brown, shading out to nearly yellow on sides, elypeus light fuscous; 
genae, antennae and eyes yellow; front and middle legs yellow, hind legs 
light brown, yellowish over apical half of tibiae and tarsi. Abdomen, 
pygofer and styles dark brown. Tegmina black or very dark fuscous 
brown, a white line along costal margin, narrowest at base where it onlv
