MEMBRA CIDjE.

The chief differences consist in U. clavata having its pronotum less elevated, 
and the absence of all the characteristic yellow markings. 
Size, 16 x 10 mm. 
B.M. Collection. 
UMBONIA ATALIBA, Fairm. 
(Plate XVII. figs. 5, 5a.) 
Fairm. l.c. p. 278, t. G, fig. 1. Fowler, l.c. p. 35, t. 3, figs. 14, 14a. Walker, Umbonia lativitta, 
l.c. ii. p. 520. 
Fairmaire gives the description—yellow, with a medial and two red bands, one 
on each side ; pronotal horn set rather behind the shoulders, the processes black ; 
tegmina subhyaline “ enfumees a l’extremite.” 
Two examples are in the Hope Collection, one of which I figure. They recall 
U. spinosa, which, however, is usually a much larger insect, and has the red streaks 
less marked. 
Size, 15 x 10 mm. 
Habitat .—North America, South and Central America. 
UMBONIA GLADIUS, Fairm. 
(Plate XVII. fig. G.) 
Fairm. plate vi. figs. 4 and 5, p. 275. Fowler, B.C.A. Tab. III. fig. 13, p. 38. 
Pronotum with an erect, thin, flat and perpendicular dorsal horn ; colour ochreous, 
with coarse punctures ; the males show a red streak on each side of this horn, which 
is nearly obsolete in the females; this process is carinated and tipped with black ; 
legs short and hirsute. The females appear to be more plentiful than the other sex, 
but examples are not common. 
The species recalls Platycotis or Enchenotype of Stal; but with reference to the 
former genus the horn is not directed forwards, and the space between the shoulders 
is wider. 
Size, 11x8 mm. 
Habitat. —Valladolid, Yucatan, Campeachy. 
UMBONIA ARTICULARIA, n.s. 
(Plate XVII. figs. 7-8.) 
Colour dark ochreous, with a rosy tint, shining and finely punctured ; pronotal 
horn erect, sharp, and compressed; immaculate ; tegmina hyaline, with yellow 
neuration, rather fuscous ; legs short, stout “ gouty legged ” ; females stouter than 
the males.
