CATHORAMA. 
Catorama, Guérin, Rev. Zool. 1850, p. 431. 
Tricorynus, Waterh. Trans. Ent. Soc. Lond. v. p. 68 (1849). 
Six species of this genus have been described, with one exception from the West- 
India Islands, the other one being from the United States of North America. The 
club of the antenne is simply formed ; that is to say, the three terminal joints are nearly 
equal in length ; but they are ten-jointed.

2. Cathorama herbarium. 
Catorama herbarium (Chev. coll. Sallé). 
Breviter oblongum, piceum, sericeum ; elytris subtilissime punctato-striatis, punctis gemellatis, stria submarginali 
duplici, antice obsoleta; subtus, cum antennis, palpis et ore, dilutius rufo-piceum. Long. 3-3; millim. 
_ Hab. Muxico, Cordova (Sal/é); Nicaragua, Chontales (Janson) ; Panama, Volcan de 
Chiriqui (Champion). 
This species is very closely allied to C. palmarum, but is considerably smaller and 
usually of a lighter pitchy colour; and in addition to these differences the elytra are 
distinctly gemellate-punctate in series. The punctures are very small, faintly impressed, 
and irregular in places, obliterated near the base. The stria nearest the margin starts 
from an elongate fossa beneath the callus, the one above it from near the callus itself ; 
they are very faintly punctured. In the Chontales specimens this sculpture is confused 
near the shoulder ; the specimens from there are also smaller on the average than the 
Mexican ones. 
3. Cathorama seminulum. (Tab. X. fig. 13.) | 
Breviter oblongum, nigro-piceum, subtiliter sericeum, elytris vix punctato-striatis, striolis duabus antice abbre- 
viatis submarginalibus ; antennis, palpis pedibusque rufo-piceis. Long. 2-23 millim. 
Hab. GuaTEMAta, near the city (Salvin), Capetillo, Duefas, Zapote, Guatemala city, 
Cerro Zunil, Aceituno, San Joaquin, Purula (Champion); Nicaracua, Chontales (Janson). 
There is in’ our collection a very considerable series of specimens, which, though 
_ varying a little in size and colour, we are disposed to unite under one specific name. 
These are generally darker in colour than C. herbariwm and smaller; but the characters
