describes the thorax as “ subtiliter rugulosus, obsoletissime punctatus,” so that Murray’s 
determination of his C’. niger must be considered as very doubtful; and it is also far 
from certain that our Chontales example is truly referable even to Murray’s species. 
Our insect may be identified by its great resemblance to C. rufipes, by the existence of 
- coarser punctures on the thorax, and by the ventral surface of the last segment in the 
male being deplanate, indeed feebly but broadly longitudinally depressed, along the 
middle, and by the large size of the pencils of erect hairs at its extremity. 
5. Conotelus nigricornis, sp.n. (Tab. IX. fig. 8, 2 .) 
Nigerrimus, opacus ; capite, prothorace elytrisque densissime obsolete punctatis ; tibiis piceis, tarsis rufis. 
Long. 4 millim. 
Hab. Muxico, Cordova (Hége) ; Panama, Boquete in Chiriqui 3500 feet (Champion). 
Very closely allied to C. rufipes, and similar thereto in size, form, and punctuation, 
but distinguished by the black antenne and dark legs; the thorax is slightly more 
narrowed in front, so that the anterior angles are rather more obtuse. 
We have received only three specimens, but both sexes are represented ; the slight 
sexual distinctions appear to be the same as in C. rufipes. 
§ 38. Hind body with depressed lateral margins ; thorax with coarse definite punctures ; 
elytra with definite punctures arranged serially. 
6. Conotelus hondurensis, sp. n. 
Niger, subopacus, antennis pedibusque sordide rufis, illis basi picea ; prothorace coriaceo et sparsim punctato ; 
elytris omnino opacis, seriatim subtiliter punctatis. 
Long. 3 millim. 
Hiab. British Honpuras, Belize (Blancaneauz). 
Head distinctly, moderately closely punctured. Thorax at the sides with the 
punctuation quite confused and indefinite, but on the disc with a more definite 
sculpture, consisting of a few not very large punctures scattered on the opaque, 
minutely sculptured surface. Elytra quite dull, with regular series of fine punctures. 
Hind body rather more shining than the other parts, finely and sparingly sculptured. 
Two examples of the male sex, with broad feet. 
7. Conotelus chiriquensis, sp. n. (Tab. IX. fig. 9.) 
Nigerrimus, subnitidus, tarsis rufis; prothorace crebrius sat fortiter punctato; elytris striato-punctatis, striis 
ad latera et ad apicem obsoletis. 
Long. 23 millim. 
Hab. Panama, Bugaba, Volcan de Chiriqui (Champion). 
Var. Angustior, fortius punctatus. 
Hab. Nicaragua, Chontales (Janson).
