This distinct little insect is unique. 
20. Huconnus mutandus. (Tab. II. fig. 9.) 
Gracilis, castaneus, elytris rufo-castaneis, pube sat elongata suberecta sat dense vestitus; antennis basi gracili,

Long. 2 millim. 
Hab. Panama, Volcan de Chiriqui between 2500 and 4000 feet (Champion). 
Antenne with the basal joint short, the second joint rather long, the third joint small, 
the fourth, fifth, and sixth joints each slightly longer; the seventh much longer, but 
scarcely broader ; the eighth not longer than the seventh, but much broader, subquadrate ; 
the ninth a little broader, evidently transverse; the tenth larger, subquadrate; the 
terminal joint short, a little longer than the tenth. Head slender, much narrowed 
behind, with elevated pubescent vertex; the eyes more convex and more convexly 
faceted than usual in this genus. Thorax rather long and slender, the transverse 
impression near the base delicate. Hlytra with rather scanty pubescence, and a slight 
humeral plica. Legs slender. | 
B. Thorax with a minute carinule at the base on each side. 
21. Euconnus guatemalenus. (Tab. II. fig. 10.) 
Rufescens, capite prothoraceque picescentibus, pube elongata sparsim vestitus; antennis sat elongatis, clava 
laxissime articulata ; capite subtransverso; prothorace suboblongo, basi utrinque tantum minute foveolato ; 
elytrorum humeris parum elevatis. 
Long. 1? millim. 
Hab. GuateMatA, El Tumbador 2500 feet, Capetillo (Champion); Panama, Volcan 
de Chiriqui (Champion). 
Antenne red; joints 3-6 small, equal, the seventh joint distinctly longer but only very 
slightly broader; club not broader towards the extremity, very loosely articuiated, the 
eighth joint rather longer than broad, the tenth hardly so long. Head short, rather 
abruptly narrowed behind, with only scanty pubescence. Thorax slender, oblong, only 
a little narrowed in front, bearing a scanty long pubescence, and with the basal fovea 
minute and close to the side. Elytra rather broad, much curvate at the sides; with 
moderately long, rather scanty, pubescence. Legs rather long and slender. 
Four examples. The Panama exponent is very mutilated and decayed, and has 
entirely lost its antenne, and may not be really conspecific.
