BRYAXIS. 31 
brevibus ; capite brevi, fronte transversim lineariter depresso, vertice bifoveolato; prothorace anterius 
profundissime transversim depresso, basi in media minutissime foveolata ; elytris intra humeros depressis, 
stria suturali integra, discoidali nulla ; abdomine subtiliter marginato, segmento basali haud elongato. 
Long. 1} millim. 
Hab. Guatemata, San Juan in Vera Paz (Champion). 
Antenne short, with a stout club; joints 3-8 minute, the eighth being exceedingly 
short, the ninth joint small, transverse, the tenth much broader and also transverse, the 
terminal joint stout, acuminate. Palpi rather long, with slender terminal joint. Head 
small, with two large fovez on the vertex, the extreme summit slightly notched in the 
middle, the front margin thickened and with a linear depression behind the incrassation. 
Thorax small, much narrowed in front and behind ; with an extremely deep transverse 
depression extending all across it in front, and an exceedingly minute punctiform fovea 
in front of the base. Elytra elongate, convex; the extreme base internal to the shoulder 
depressed. First dorsal ring not much longer than the second. 
Of this Bythinoid insect only a single example was secured. 
17. Bryaxis vulnerata. (Tab. I. fig. 15.) 
Castanea, subtiliter pubescens; antennis brevibus; prothorace transverso, medio profunde irregulariterque 
depresso, basi in media minutissime foveolata; elytris intra humeros depressis, stria suturali integra, 
discoidali nulla; abdomine subtiliter marginato, segmento basali haud elongato. 
Long. 13 millim. 
Hab. Panama, Tolé (Champion). 
Antenne short and slender, with rather large club; joints 4-8 minute, subequal, the 
terminal three gradually forming a club. Head short, moderately broad, the front of 
the clypeus a little raised and with a slight antennary tubercle; bifoveolate between 
the eyes, the extreme vertex in the middle slightly notched or depressed. Thorax broad 
and short, much narrowed behind ; with a very large and deep depression formed as it 
were of three depressions united, the larger on the disc, the smaller one a little nearer 
the front on each side. Elytra with a distinct sutural stria and a well-marked intra- 
humeral depression. 
Allied to B. impressicollis, though with a differently formed thorax ; also unique.

Castanea, nitida, levigata ; antennis tenuibus, clava uni-articulata; capite utrinque foveolato, tuberculis anten- 
nariis discretis; prothorace basi in media minute foveolato; elytris stria suturali integra; abdomine 
brevissimo, segmento basali parum elongato, ceteris deflexis. 
Long. 1} millim. 
Hab. Guatemata, Paraiso (Champion). 
Antenne slender; joints 3-10 minute, similar ; the terminal joint forming a rather 
large club, acuminate. Head small. Thorax rather elongate, the base produced in 
front of the scutellum ; with a very minute fovea in the middle close to the base.
