between the sutural and discoidal striz, as well as a puncture at the base of each of 
these strie. 
Seven examples; these were found on the sandy banks of streams.

This species is said to be nearly or quite without lateral foveze on the thorax, and to 
be scarcely 1 millim. long.

The thorax of this insect is stated to have a very fine crest in front of the scutellum ; 
the lateral fovese absent, or rather replaced by a fine linear impression composed of 
confluent punctures ; the head to be only depressed between the antenne (as in B. celata) ; 
the length 14 millim. 
15. Bryaxis bythinoides. 
Castanea, subtiliter pubescens ; antennis tenuibus, distantibus ; capite brevi, lato, bifoveolato; prothorace trans- 
verso, basi in media minutissime foveolata, lateribus haud foveolatis ; elytris intra humeros foveolatis, 
stria suturali integra, stria discoidali nulla; abdominis segmento basali parum elongato, lateribus haud 
alte marginatis. 
Long. vix 13 millim. 
Hab. Panama, Volcan de Chiriqui 4000 to 6000 feet, Pefia Blanca 3000 to 4000 feet 
(Champion). 
Antenne with small third joint which, however, is longer than the fourth, joints 4-8 
each quite small and slender, the ninth slightly larger, the tenth transverse, the terminal 
joint acuminate and longer than the preceding two together. Head broad and short, 
the vertex with two large but indefinite fovee, the front depressed but not foveolate. 
Thorax short, strongly narrowed behind. Elytra of a rather darker castaneous colour 
than the head and thorax; with a rather large fovea at the shoulders, and a very deep 
sutural stria. Legs slender and rather short. In the male the intermediate ventral 
rings are so abbreviated as to be almost invisible, and the apex is occupied by a deep 
transverse fissure. 
One example from each locality.

Nigro-picea, convexa, parce subtiliter pubescens, nitida; antennis, palpis pedibusque sordide testaceis, illis.
