This fine insect does not seem to be common in Central America. 
Colour fine ochreous yellow, punctured, with one or more pronounced red streaks 
from the top of the dorsal horn to the proceplialon; the base of this sharp thornlike 
pronotal horn extends beyond the tips of the tegmina. Though the abdomen of the 
female is robust, it is covered by the pronotum ; the tegmina are subhyaline, with 
a fine neuration dividing the membranes into elongated cellules; supra-humerals are 
more conspicuous from the dorsal than from the frontal aspect; legs stout; hind tarsi 
short; tibiae often with a red longitudinal streak. There is much variation in the 
intensity of the red streaks. 
In the National Collection there is a specimen with dark tips to the wings, 
Expanse, 33 mm. 
Size, 15 x 12 mm. 
Habitat. —Erom Guatemala to Brazil. 
UMBONIA JAVANENSIS, n.s. 
(Plate XVII. fig. 1.) 
This insect at first sight might be thought to be a large example of (J. spinosa. 
but apart from its greater size, it has several other differences. 
The pronotum is deeply punctured, and also striated all over its surface ; its 
colour is more rufous and glaucous, with the point of the dorsal recurved process 
black; the tegmina are shining and much darker than in U. spinosa; the abdomen 
is large, and slaty grey. As in other species of this genus, the hind tarsi are very short; 
the first and second pairs of legs are the longest. 
U. orozimbo also is different, and is an American species. 
Size, 17 x 11 mm. 
Habitat. —Java.
