GONIOLCIUM.—LIBURNIA. 133 
appearing as a mere thickening (as is sometimes the case in species of Oliarus); second joint of the 
antenne ringed ; keels of the pronotum and scutellum very distinct, whitish ; tegmina transparent, with 
two irregular bands across them (when closed), and sometimes other markings, and with the apical 
portion more or less distinctly dark internally, the veins with large dark granulations throughout; legs 
whitish, very neatly and regularly ringed with black. 
Male with the anal tube moderately large, produced behind into a strong, sharp, curved hook; styles long, 
robust, almost straight, gradually dilated towards the apex, with the apices truncate. 
Female with the anal tube rather long and the anal style distinct, and with a very long and strongly curved 
ovipositor. 
Long. cum tegm. 4-43 millim.; lat. ad hum. 1-14 millim. (6 9.) 
Hab. Mexico, Orizaba (F. D. Godman and H. H. Smith), Omilteme, Amula, and 
Chilpancingo in Guerrero, Fortin in Vera Cruz (H. H. Smith); Guatemata, San 
Gerdnimo, San Joaquin, and Chiacam in Vera Paz, San Isidro (Champion). | 
We have also a female specimen from Juarez, N. Mexico (Cockerell), which closely 
resembles this species, but.the keels of the pronotum are not so strongly angled ; it is, 
however, in poor condition. ‘The example figured with the wings extended is from 
Amuia. 
2. Goniolcium testaceum, sp.n. (Tab. XIII. figg. 9, 9a.) 
Precedente major, carine frontalis bifurcatione magis distincté, et colore uniformi testaceo, carinisque late- 
ralibus scutelli rectioribus distinguendus. 
Mas minor, tuba anali magna, processu longo acuto; stylis robustis, carinatis, antice subtruncatis utrinque 
plus minusve distincte productis. 
Of a uniform testaceous colour, with the frontal keels lighter; the forehead is rather longer than in the 
preceding species, and the bifurcation of the central keel more distinct; the keels are not so strong, 
and those on the scutellum are straighter; the granulations of the tegmina are strong, but are less 
evident than in the preceding species, because of their light colour. . 
Male smaller, with the anal tube large, and with a sharp process behind; styles robust, keeled on the outer 
edge, and with the apex truncate, the truncate part being produced on each side, and on the inner side 
terminating in a small hook. 
Long. cum tegm. 5-6 millim.; lat. ad hum. 13-2 millim. (<¢.) 
Hab. Guatemata, Senahu in Vera Paz, Cerro Zunil (Champion). 
One male and three females. The last segment of the single male obtained is not 
perfect, and one style is wanting, but the shape of the other is quite plain under a 
compound microscope, although the parts are somewhat confused.

there are a very considerable number.
