as shown in Dr. Horn’s figure, are, it is true, slightly different 
from those of A. dubius, but no reliance can be placed on 
this character. 
COLYDITDAE. 
PSEUDAULONIUM. 
Pseudaulonium, Reitter, Stett. ent. Zeit. 1877, p. 334. 
This genus was based upon two species, P. regale, from 
Colombia, and P. ferrugineum, from Brazil. There are 
numerous specimens of the latter, from Rio Janeiro and 
Parana, in the Fry collection at the British Museum. 
Two others are now added. These were placed amongst 
the “‘ genera incertae sedis’? when our collections were 
sorted, and were thus not seen by Dr. Sharp when he 
enumerated the Central American Colydiidae. The tarsi 
are 4-, and the antennae 11-jointed, the terminal three joints 
of the latter being dilated into a large club. 
*Pseudaulonium discolor, n. sp. (Plate ITI, figs. 5, 5a, 3.) 
Elongate-oval, rather convex, densely alutaceous, dull; ferru- 
ginous, with the dise of the thorax and a large, common, elongate 
or oblong patch on the elytra fuscous or black, the dark markings 
sometimes obliterated and sometimes black and sharply defined, 
the head (except in front) and the two basal joints of the antennal 
club infuscate in one example. Head minutely punctate, bifoveate, 
the eyes large; antennae with the joints preceding the club about 
as broad as long. Thorax convex, slightly broader than long, the 
explanate margins somewhat rounded and crenulate, the base 
distinctly margined, the anterior angles not prominent, the hind 
angles acute; densely, minutely punctate, the raised submarginal 
line on each side rather prominent. LElytra a little wider than the 
thorax, the humeri angular; minutely seriato-punctulate, the 
interstices flat and densely alutaceous. Beneath alutaceous, dull, 
sparsely, minutely, the thorax more coarsely, punctate. Prosternal 
process rather broad, abruptly declivous behind. 
Length 24-34 mm. (J 9.) 
Hab. Panama, Volcan de Chiriqui, Bugaba (Champion) ; 
Brazit, Rio Janeiro, Bahia, Parana (coll. Fry). 
Nine specimens, all but two from Brazil, varying greatly 
in the development of the dark markings on the upper 
surface. Smaller than, and perhaps an extreme form of,
