3. Thinobius curtellus. 
Fuscus, abdomine nigricante, antennis, pedibus elytrorumque apice testaceis; antennis minus elongatis ; 
omnino subtilissime punctulatus. 
Long. 1 millim. 
Hab. Guaremata, near the city, San Gerénimo (Champion). 
Antenne clear yellow, rather stout; fifth joint considerably longer than broad, longer 
than either of those adjacent to it; ninth and tenth joints scarcely transverse ; terminal 
joint moderately long. Head subcircular. Thorax rather strongly transverse, much 
rounded at the sides. Elytra nearly twice as long as the thorax. Hind body distinctly 
punctulate and pubescent. Nine examples. 
4, Thinobius nigricans. 
Niger, pedibus sordide testaceis; angustus, subtilissime punctulatus, opacus; capite parvo; antennis haud 
elongatis, crassiusculis. 
Long. 13 millim. 
Hab. Guatemata, San Gerénimo (Champion). 
Antenne evidently thicker externally, dark fuscous, the penultimate joints a little trans- 
verse. Head rather short and broad, slightly broader from behind the eyes, and rather 
abruptly narrowed at the neck. Thorax rather strongly transverse. Hlytra one and a 
half times as long as the thorax. Unique. 
5. Thinobius agilis. 
Minutissimus, angustus, niger; antennis pedibusque testaceis, illis minus elongatis, crassiusculis ; obsolete: 
punctulatus.

Long. 2? millim. 
Hab. Guatemata, near the city, San Gerénimo (Champion). 
Antenne short and stout; third joint not longer than broad, the fourth strongly trans- 
verse, the fifth rather longer, the sixth similar to the fourth, the four following joints 
rather broader, differing little from one another, transverse, the terminal joint quite twice 
as long as the tenth. Head elongate. Thorax with the sides and base much rounded, 
nearly twice as broad as long. Elytra much longer than the thorax. Hind body rather 
narrower at the base than near the apex. 
This is one of the most minute species of Coleoptera, nevertheless Mr. Champion 
secured and preserved a dozen examples. 
THINOPHILUS. 
Thinophilus, Rey, Hist. Nat. Col. Fr. Oxyteliens, p. 822 (1879) *. 
This genus has recently been established to receive a portion of the European species 
* This generic name has long been preoccupied in Diptera (Wahlb. 1844) and cannot be retained in. 
Coleoptera ; for the purposes of this work, however, I have not thought it necessary to change it.
