PTERYGIA.—HYPSOPRORA. 25 
from the apex of the metopidium to the apex of the pronotum, and the upper surface is more or less 
spinose in parts, and strongly though remotely punctured; tegmina opaque, fuscous, variegated with 
brown or brownish testaceous ; legs fuscous. 
Long. 6 millim.; lat. 5? millim. 
Hab. Guatemata, Teleman, Panima, and Panzos in Vera Paz (Champion) ; PANAMA, 
Bugaba and Caldera in Chiriqui (Champton). 
Five specimens; one from Teleman is figured. 
HYPSOPRORA. 
Hypsoprora, Stal, Ofv. Kongl. Vet.-Ak. Férh. xxvi. p. 277 (1869). 
Achmophora, Stal, loc. cit. p. 278 (ex parte). ; 
The type-forms of Stal’s subgenus Achmophora (4. elephas and 4. recticornis) must 
be referred to Walker's genus Philya; but Achmophora coronata, Fabr. (= Pterygia 
varia, Walker), seems to be closely related to certain forms of Hypsoprora, and I have 
therefore placed it under that genus, together with the other species of Pterygia which 
have no horns at the side of the pronotum above the shoulders. In all these forms the 
pronotum is more or less extended in front into an erect process, which in some cases is 
broadly rounded and very obtuse, and in others very much elongated; this process is 
wanting in the species of Pterygia proper. 
1. Hypsoprora trituberculata, (Tab. II. fig. 15, 15a, 153.) 
Pterygia (Hypsoprora) trituberculata, Stal, Ofv. Kongl. Vet.-Ak. Forh. xxvi. p- 278°. 
Hab. Mexico (Sallé; Mus. Holm.!); Panama, Bugaba (Champion).. 
The specimen from Bugaba may belong to a:distinct species, as it is smaller, with the 
pronotum narrower, and differs somewhat in the relative size of the dorsal protuber- 
ances ; without further material, however, it can hardly be regarded as separate. A 
Mexican example is figured. 
2. Hypsoprora nigerrima, sp.n. (Tab. II. figg. 14, 14a.) 
Tota nigra; capite levi, distincte punctato; metopidio tuberculato; pronoto scabro, fortiter punctato, rugoso, 
parte antic4, intermedia et postica plus minusve elevata, dorso sinuato, apice obtuso, protuberantia posticd 
lat&é latera pronoti excedente, postice dilataté ; tegminibus nigris, opacis, ad basin punctatis; pedibus 
nigris, tibiis tarsisque interdum dilutioribus. 
Of a deep black, moderately shining, with the metopidium and other portions of the pronotum more or less 
tuberculate ; pronotum rugose and coarsely punctured, with the dorsum more or less strongly sinuate, and 
divided into three elevations, which appear o vary in size and elevation in different specimens, the hinder 
one being the broadest and least elevated, and, if viewed from above, dilated strongly behind ; tegmina 
black, opaque, together with the apex of the prothorax occasionally indistinctly irrorated with minute 
yellowish or whitish spots; legs black, tarsi sometimes lighter. 
Long. 33-4 millim. ; lat. 1? millim. 
Hab. Mexico, Atoyac in Vera Cruz (Schumann); GuaTEMALA (Mus. Brit.), EL Tum-— 
bador 2500 feet (Champion).
