OXYTELUS. 691 
9. Oxytelus fragilis. 
Minutus, opacus, niger; pedibus testaceis; densissime subtilissime strigosulus ; prothorace fere equali. 
Long. 13 millim. 
Hab. Guatemata, El Tumbador, San Joaquin, San Juan in Vera Paz (Champion) ; 
Panama, Volcan de Chiriqui (Champion). 
Extremely similar to the European O. depressus ; resembling also the North-American 
O. nanus, Er., but readily distinguished by the absence of the slightly polished lines 
which mark the limits of the thoracic grooves in that species. The antenne are 
entirely black; joints 3 and 4 very small, 5-10 transverse. Head very minutely 
strigose, quite dull, without depression on the vertex, the front margin of the clypeus 
feebly shining. Thorax strongly transverse, the grooves just perceptible and rather 
broad, the whole surface quite dull. Elytra longer than the thorax, and almost as 
finely strigose. Hind body very feebly, scarcely perceptibly, punctured. 
The small series (nine examples) obtained of this obscure species does not exhibit, so 
far as I can see, any conspicuous sexual differences; but the specimens are in very 
decayed condition, so that I cannot examine them thoroughly. 
10. Oxytelus emeritus. 
Minutus, nigricans, omnino subtilissime strigosulus, subnitidus ; pedibus testaceis; prothorace trisulcato. 
Long. 2 millim. 
Hab. Guatemara, San Joaquin, San Gerénimo (Champion). 
Head shining, the clypeus polished, the vertex with a definite fovea in front. Thorax 
strigose; the grooves present, the spaces separating them polished and rather broad. 
Elytra longer than the thorax, dull, excessively minutely strigose. 
Only two examples of this minute Oxytelus were obtained : I believe they represent 
the sexes though I see nothing very conspicuous to indicate it. 
§2. Thorax with a large and very deep impression on each side near the lateral margin. 
11. Oxytelus spinifrons. (Tab. XVIII. fig. 11, ¢.) 
Niger; mandibulis, antennarum basi, pedibus elytrisque testaceis, his brevibus, strigoso-punctatis ; prothorace 
profunde trisulcato. 
Mas clypei medio triangulariter subspinoso-producto. 
Long. 33-4 millim. 
Hab. Nicaragua, Chontales (Janson). 
Antenne with the four basal joints yellow or red, the others dark; terminal joint 
elongate, acuminate. Head much larger in the male than in the female; vertex 
punctate-strigose, and with three depressions, these depressions as well as the sculp- 
ture much more largely developed in the male than in the female; the anterior
