known from the former by the extra discoidal area of the tegmina and the very 
prominent eyes, and from the latter by the extra discoidal area of the wings and the 
shape of the pronotal process. 
1. Centruchoides laticornis, sp. n. (Tab. X. figg. 6, 6a.) 
Fuscus vel fusco-brunneus, pronoto sparsim breviter pubescenti, subrugoso, lineé centrali elevata, remotius 
punctato, punctis magnis haud profundis; scutelli apice utrinque plerumque dilutiori ; tegminibus opacis, 
maculis quibusdam parvis flavo-albescentibus interdum instructis; abdomine cereo vel cereo-tomentoso ; 
pedibus ferrugineis, plus minusve infuscatis. 
Of a fuscous or fuscous-brown colour, but variable, the lighter specimens having the head, the front of the 
pronotum, and the base of the tegmina more or less testaceous, the darker specimens being almost 
unicolorous ; pronotum with a very distinct central line, rugose at the sides, set with large and not very 
closely placed punctures; scutellum usually lighter at its apical points; tegmina brown, with the veins 
unicolorous, nearly always with a small dirty-whitish spot of pubescence just in the middle, and sometimes 
with others towards the apex; these appear, however, to be very fugitive; abdomen covered with a 
whitish or yellowish waxy-looking substance, the front parts pubescent; legs ferruginous, more or less 
infuscate. 
Long. cum tegm. 7-9 millim.; lat. int. corn. 4-5 millim. 
Hab. Panama, Bugaba, Volcan de Chiriqui 2000 to 3000 feet (Champion). 
The variation in the form of the horns of this species is probably not a sexual 
character, as at first I thought might be the case: in one small specimen they are 
notched in such a way as to be quite curved and pointed at the apex. The waxy 
secretion on the abdomen appears to have as its foundation a whitish tomentose 
pubescence. | 
In facies this species strongly resembles Centruchus fuscipennis, Stal (= Centrotus 
Suscipennis, Germ.), a South-African species. 
SMERDALEA, gen. nov. 
Robusta, scabra, fronte lata, angusté, ineequali, ad latera bilobaté, antennarum setis e lobis procedentibus, 
ocellis inter se quam ab oculis minus distantibus, oculis valde prominulis; humeris a fronte visis breviter 
sed acute prominulis ; pronoto pube recumbenti vestito, aspero, cornibus duobus anticis permagnis, latis, 
serratulis, mucronibus quibusdam majoribus instructis, ante basin in processum magnum extenso; basi 
pronoti truncata; processu elongato ad basin dilatato deinde tenuiori, et ad apicem iterum expanso, 
fortiter trispinoso ; scutello prelongo, triangulari, ad basin elevato, et protuberantié lata posticé, apicem 
dilatatum processus pronoti attingenti, instructo; tegminibus amplis, intectis, corio areis apicalibus 
quinque, discoidali una, suturé clavati perdistincta ; alis areis apicalibus quatuor, secunda haud stylata ; 
pedibus teretibus, tibiis posticis extus utrinque minute serratulis. 
A stout and rugged-looking species, the general form, if viewed from directly above, being that of an elongate 
reversed isosceles triangle ; head produced in front, forehead broad and narrow, with the ocelli distinct, 
situated nearer to one another than to the eyes ; above the ocelli are two or three small depressed shining 
callosities, which in some lights resemble extra ocelli; eyes very strongly prominent, almost petiolate; 
pronotum with the shoulders slightly but sharply prominent, with two very large and broad antlered horns 
in front, which are rough and serrate; behind these and just before the base of the pronotum, which is 
distinct and truncate, there is a long posterior process, which is considerably elevated above the scutellum, 
dilated at the base, then narrowed, and strongly dilated and trispinose behind in the form of a reversed 
bird’s-foot, the hinder spine being the longest; scutellum long, triangular, pointed at the apex, raised at
