224 STAPHYLINID. 
at some distance from the suture; and the sixth dorsal plate of the hind body has a 
carina on the middle behind. os 
This is a very Homalotoid species in appearance, but not in structure; the ligula is 
elongate and linear; and the mesosternal process is comparatively little prolonged 
between the middle coxe. 
10. Hoplandria debilis. 
Nigra, nitidula, pedibus testaceis, antennarum basi sordide testacea ; abdomine nitidulo, segmentis 2°-5™ summa 
basi fortiter punctata, preeterea levigato. 
Long. 33 millim. 
Mas elytris singulis ad medium apicis tuberculo elongato, acuminato, recurvato ; abdominis segmento 6° dorsali 
carinula elevata. 
Hab. GuateMata, Guatemala city, San Gerénimo, Paraiso 300 feet (Champion). 
Antenne slender at the base, gradually thickened from the fourth to the tenth joint ; 
third joint rather shorter than second, fourth slender, tenth distinctly transverse ; 
eleventh rather large, the apex more or less distinctly paler in colour. Head rather 
broad, indistinctly punctured. Thorax strongly transverse, the base rounded, the hind 
angles very indistinct, but present, the surface indistinctly punctate, but the pubescence 
rather conspicuous. Elytra not broad, moderately distinctly punctate, very distinctly 
pubescent. Hind body very shining, but with a band of dense rugose sculpture at the 
base of each of the anterior segments. Legs pale yellow. 
The individuals of this species have much the appearance of some of the European 
Homalote, such as H. fungi. The dense and deep punctuation at the base of each of 
the anterior abdominal segments, in strong contrast to the very smooth posterior portion of 
the plate, is almost peculiar to the species; but this punctuation can only be seen when 
the hind body is extended to its natural length. 
Five individuals have been found, only one of which (an immature example from 
San Gerdnimo) is a male. 
CHAROXUS. 
Tibize anteriores, dense fortiterque spinulose, intermedi et posteriores mutice. Mandibule elongate, mutice. 
Caput elongatum, antennis fere in marginem anteriorem insertis. Prothoracis margo lateralis ad angulos 
posteriores angustus, in medio et anterius nullus. 
The position of the anomalous little insect for which I propose this generic name is 
at present a question of some doubt, as the middle tarsi have apparently only four 
joints, which would indicate that the insect must be placed in the Bolitocharates; I 
believe, however, that there is a very short basal joint present in addition to the four 
that are conspicuous. ‘The insertion of the antenne almost at the front margin of the 
head would suggest that the insect is a member of the subfamily Staphylinini rather 
than of the Aleocharini; but, notwithstanding these facts, I think that the genus Porus
