28 PSELAPHID. 
8. Bryaxis intacta. 
Picea, elytris piceo-rufis, convexa, subtilissime pubescens ; antennis maris articulo quinto valde inflato; capite 
nitido, trifoveolato, foveola frontali magna; prothorace basi in media foveola punctiformi, utrinque foveola 
majore ; elytris stria discoidali apicem haud attingente, stria suturali integra ; abdominis segmento basali 
sat elongato, quam secundum fere duplo longiore. 
Long. 2 millim. 
Hab. GuateMata, Cahabon 1000 feet (Champion). 
The male of this species has the fifth joint of the antenne greatly enlarged and 
foveolate-impressed in front, all the other joints being normal, the sixth, seventh, and 
eighth small, slender, and subequal, the terminal three joints forming an elongate very 
slender club; it also has a conspicuous mucro directed inwards on the middle tibia just 
above the apex. 
The male of B. tntacta is readily distinguished from the same sex of B. salla@i by the 
structure of the antenne ; the female is unknown. Unique. 
9. Bryaxis diversicornis. 
Picea, elytris piceo-rufis, convexa, subtilissime pubescens; antennis maris articulis quinto sextoque incrassatis ; 
capite brevi trifoveolato, foveola frontali magna; prothorace basi in media foveola punctiformi, utrinque 
foveola multo majore ; elytris stria discoidali omnino obsoleta ; abdominis segmento basali sat elongato, 
quam secundum haud duplo longiore. 
Long. 2-23 millim. 
Hab. GuateMaa, Sabo in Vera Paz (Champion). 
This insect is very closely allied to B. sall@i, but has the discoidal stria of the elytra 
quite obsolete, and the antenne of the male more peculiarly formed; in this sex the 
fifth antennal joint forms an irregular triangle, and is curvate and hollow in front, and 
the sixth joint is transverse; in the female the fifth and sixth joints are not dilated, 
but the fifth is as long as the preceding two together, and the sixth intermediate in 
length between the fifth and seventh; the male has the metasternum angularly promi- 
nent on either side, subexcavate between the prominences. There is a very slight 
intrahumeral depression on the wing-case, but no discoidal stria, the sutural stria being 
present as usual. 
Only three examples were obtained. 
10. Bryaxis rubecula. 
Fem. Rufo-testacea, convexa, nitida, subtiliter pubescens; antennis tenuibus, articulo quinto vix elongato, 
tertio equali; capite argute trifoveolato, foveolis omnibus pubescentibus ; prothorace subgloboso, basi in 
media foveola punctiformi, utrinque foveola majore; elytris stria discoidali omnino obsoleta; abdominis 
segmento basali sat elongato, quam secundum vix duplo longiore. 
Long. 2 millim. 
Hab. Panama, Volcan de Chiriqui 2500 to 4000 feet, Los Remedios (Champion). 
Although we have received only females this is clearly a distinct species, and the 
absence of a definite discoidal stria induces me to place it next B. diversicornis ; it is
