with a thin row of long hairs; hind legs (males) with trochanter 
unarmed; femur moderately swollen, armed beneath with two long 
rows of short blunt spines, the front row with the spines more numer- 
ous, more closely set, and usually with one or two larger ones near 
apical third of segment; tibia with two rows of short dark teeth, with 
an angulate apical spur; tarsal segment IT slightly longer than ITT, 
hind femur of female not as thick as male, spines not as numerous 
and unarmed on basal fourth; tibia with two rows of closely set teeth. 
MacroprEerous ForRM: Pronotum more convex and median carina 
a little more developed than in brachypterous form; backward pro- 
jection of pronotum, shieldlike; hemelytron dark fuscous, membrane 
brownish fuscous; veins of corium prominent, dark, with short dark 
hairs interspersed with short silvery hairs; mesothoracic wings clouded 
with fuscous; female slightly more robust than male. 
Holotype male and allotype female, both apterous, and 16 para- 
types: Compostela, Nayarit, Mexico, Aug. 26, 1959, Arnold Menke; 
50 additional paratypes: Compostela, Nayarit, Mexico, Dec. 30, 1958, 
A. 5S. Menke and L. A. Stange. The following metatypes have been 
seen: 1 specimen, Bagaces, Guanacaste, Costa Rica, July 13, 1957, 
D. R. Lauck; 1 specimen, 18 miles northwest of El Camaron, Oaxaca, 
Mexico, Aug. 20, 1959, A. Menke. The holotype and allotype will 
be returned to the Los Angeles County Museum along with some 
paratypes. Additional paratypes are in the private collections of the 
authors, the U.S. National Museum, and the California Academy of 
Sciences. 
This species resembles V. pueblana Drake, but is readily distin- 
guished from it by the vertical furrows on abdominal pleurities IT and 
III only and by the differently shaped male parameres (pl. 3,c). These 
same characters and the concolorous antennal segments separate it 
from V. cinctipes Champion. 
The large series from Compostela was collected from the under- 
surface of a rock which projected over the water from the bank of a 
small stream. The undersurface of the rock was approximately 2 to 
3 inches above the water surface, and the bugs were netted after 
splashing water at the underside of the rock.
