OLIBRUS. 251 
tures, still more abbreviated both at the base and apex. Two specimens only in 
bad condition have been received from Guatemala. 
The small series of Mexican examples has been forwarded to me since the above 
description was made; none of these specimens have the sculpture so well developed 
as the typical examples from Guatemala. 
8. Olibrus porrectus, sp. n. 
Rotundato-ovalis, sat convexus, sat nitidus, testaceus, supra fusco-piceus; elytris stria suturali impressa. 
Long. 13-2 millim. 
Hab. Mexico, Atoyac, Teapa (H. H. Smith), Orizaba (H. H. Smith & F. D. Godman) ; 
British Honpuras, R. Hondo, Belize (Blancaneauax) ; GuaTEMALA, near the city, Duefhas, 
Calderas, Senahu, Tamahu, San Juan in Vera Paz (Champion); Nicaragua, Chontales. 
(Janson); Panama, Bugaba, Volcan de Chiriqui (Champion). 
Antenne yellow, with slender elongate club. Thorax not margined at the base in 
the middle. Elytra with a sutural stria extending about halfway to the base, almost 
destitute of traces of striation or punctuation. 
I have great doubts whether this obscure little insect should be placed in Olibrus, 
the metasternum being more prominent than usual, and the basal joint of the hind 
foot very short; but it is perhaps better not to separate it on these characters at present. 
O. porrectus bears a very great resemblance to 0. mexicanus, but is a good deal smaller, 
and has the thorax more obsoletely margined at the base in the middle. Isee no other 
characters by which the two can be distinguished when the upper surface is looked at; 
but beneath the metasternum is a little different, and the spurs of the hind tibie are 
quite minute in O. porrectus, and larger in O. meaxicanus. 
This unattractive insect is probably the commonest, as it is also apparently the most 
generally distributed, of the Phalacride of our region. It varies greatly in size and 
also in the depth of coloration of the upper surface, but I can find no satisfactory signs 
of there being more than one species; the specific characters are, however, so slight in 
this family of beetles that it may prove otherwise when better series of examples are 
obtained. The larger number of our specimens were procured in British Honduras, 
- and amongst these all the varieties in size are illustrated. 
9. Olibrus submaculatus, sp. n. 
Rotundato-ovalis, sat convexus, rufo-testaceus, supra piceo-rufus, antennis, pedibus elytrorumque maculis 
magnis vagis quatuor, testaceis. 
Long. 2 millim. 
Hab. Mexico, Jalapa, Acapulco (Hége), Teapa (H. H. Smith); Brivis Honpvras, 
R. Hondo (Blancaneaur); GuaTeMaLa, Rio Maria Linda (Champion); Nicaragua, 
Chontales (Janson).
