B. parviceps still more closely resembles Decarthron cochlearifer, but has the antenne 
more slender, and with eleven joints instead of ten, and a less elongate first segment to 
the hind body. The male is distinguished by an elongation of the fifth and sixth joints 
of the antenne, and a slight asymmetry of the seventh and eighth joints. 
I have seen four examples from Mexico, these being mixed in Sallé’s collection with 
Decarthron cochlearifer, two from Guatemala, and one from the State of Panama. 
3. Bryaxis crassipalpis. 
Piceo-rufa, nitida, elytris sanguineis, antennis pedibusque rufis, subtiliter pubescens; capite angusto, utrinque 
supra antennas fortiter elevato, vertice bifoveolato ; prothorace transverso, basi in media foveola parva, 
utrinque foveola multo majore; elytris stria discoidali ultra medium abbreviata; abdominis segmento 
basali elongato, quam secundum plus duplo longiore. 
Long. 2 millim.

This species is readily distinguished by the strong elevation over each antenna, and 
the surface being foveolate between the excavations ; it also has the palpi thicker than 
ordinary, and more like what exists in Decarthron, from which genus-it is in fact solely 
distinguished by the eleven-jointed antenne. These last-named organs are slender, 
with quite short basal joint, the fourth joint slightly, the fifth distinctly, elongate, the 
three following joints small, and the three terminal joints forming a slender club. 
The unique example is probably a female. The pubescence in B. crassipalpis is fine 
but somewhat elongate, and not so extremely minute as in B. sall@i and its allies. 
4. Bryaxis pubescens. | 
Bryaxis pubescens, Schauf. Sechzig neue Pselaph. p. 16°. 
Hab. Mexico }. 
This insect is stated to have the head trifoveolate, the foveee adorned with white sete, 
and to be 12 millim. long; these characters would bring the species near 2. rubecula, 
but the sixth joint of the antenne is stated to be as long as the preceding two together, 
whereas in B. rubecula this joint is shorter than the fifth alone. 
5. Bryaxis nominata. 
Fem. Rufo-testacea, nitida, convexa, subtilissime pubescens; antennarum articulo quinto precedentibus duobus 
quali; capite elongato, nitido, impunctato, anterius plano, vertice bifoveolato ; prothorace basi in media 
minute foveolato, utrinque foveola majore ; elytris stria suturali aliaque discoidali ante apicem abbreviata 
impressis ; abdominis segmento basali sat elongato, quam secundum haud duplo longiore. 
Long. 2 millim. 
Hab. GuateMALA, Duefias (Champion). 
We have received only females of this species, but it is clearly quite different from 
any other noticed here; in its bright colour it resembles B. celata and B. parviceps, 
but the head is quite flat in front, and the eyes are not placed so near to the vertex; the
