BRYAXIS. 25 
far from agreeing énter se, except in the negative character of wanting the lateral thoracic 
fovee, and as no sufficient material has been obtained for the investigation of these 
minute forms, I am obliged to leave them in Bryaxis at present. 
§1. Thorax with a well-marked lateral fovea on each side; elytra usually with a 
dorsal stria. 
1. Bryaxis celata. 
Rufo-testacea, nitida, subtiliter pubescens; antennis tenuibus; prothorace basi in media foveola punctiformi, 
utrinque foveola multo majore; abdominis segmento basali haud elongato, quam secundum dimidio 
longiore, 
Long. 13 millim. 
Hab. Mexico, Jalapa (Hége); GuatTeMaLa, near the city (Champion); Nicaragua, 
Managua (Sa//é). 
Antenne quite slender ; joints 3-8 similar to one another, small, the fifth joint only 
slightly longer than those adjoining it, the ninth small, though slightly larger than the 
preceding one, the tenth larger than the ninth, as long as broad, the terminal joint still 
larger. Head without fovea in front, but slightly depressed between the antenne, the 
vertex with two large fovee. Thorax broader than long. Elytra with an entire sutural 
stria, and with a fine discoidal stria extending more than half the length. First abdo- 
minal segment with a short plica on each side. The male is distinguished by the 
existence of a long depression at the apex of the hind body beneath. 
This species is extremely similar to the female of B. reichei, but the tenth joint of 
the antenne is smaller; the head is more elongate, and somewhat depressed between 
the insertion of the antenne, and has no fovea there; the lateral fovea of the thorax 
is larger, and the pubescence though very fine is not so extremely minute. Only one 
example has been received from Mexico; Mr. Champion, however, met with a small 
series in Guatemala, and M. Sallé a single specimen in Nicaragua. 
2. Bryaxis parviceps. 
Rufo-testacea, nitida, subtiliter pubescens; antennis tenuibus, modice elongatis; capite brevi trifoveolato, 
foveola frontali magna; prothorace basi in media foveola punctiformi, utrinque foveola majore ; elytris 
stria discoidali valde abbreviata; abdominis segmento basali sat elongato, quam secundum duplo longiore. 
Long. vix 13 millim. 
Hab. Mexico, Cordova (Sallé); Guaremata, Paso Antonio (Champion); Panama, 
near the city (Champion). 
Though very similar to B. celata, this species is distinguished by the smaller head, 
with large frontal fovea; the smaller lateral fovea of the thorax; the more abbreviated 
discoidal stria of the elytra; the longer basal segment of the hind body; and the hind 
margin of the wing-cases pubescent in the middle. This latter character is wanting in 
the female of B. reichei, which also has only a minute fovea on the front of the head.
