174 STAPHYLINIDA. 
In this species the middle coxe are by no means contiguous, the metasternum is a — 
good deal produced between the middle cox, and the mesosternum is also prolonged 
to about a similar length; the apices of the two processes are not, however, contiguous, 
but are separated by a rather elongate, narrow intercoxal isthmus. ‘The insect may 
prove entitled to generic rank on account of its more than usually prolonged meta- 
sternal process and the rather less approximate coxe; and by these characters, as well 
as somewhat by the form and sculpture, an affinity with Zachyusa is suggested: the 
hind tarsi, however, are rather stout and only of moderate length, the basal joint 
slightly longer than the following one. ‘The middle tarsi are undoubtedly five-jointed. 
Only a single individual has been found; it is in a bad state of preservation, and 
apparently a female. 
4. Homalota centralis. 
Nigra, capite thoraceque vix subsnescentibus, antennis pedibusque fusco-testaceis, elytris fuscis; antennis 
gracilibus, articulis penultimis haud transversis; prothorace subquadrato, sparsim punctato; elytris hoc 
longioribus, parce punctatis ; abdomine segmentis 2°-4™ parcius punctatis, 5° et 6° fere levigatis. 
Long. 43 millim. 
Hab. GUATEMALA, Totonicapam 8000 to 10,500 feet (Champion). 
Antenne slender, strongly setose ; third joint a little longer than second; fifth to ninth 
each very slightly broader than its predecessor, the ninth longer than broad (terminal 
joints broken off). Thorax rather narrower than the elytra, a little broader than long, 
nearly straight at the sides, but a good deal narrowed and rounded near the front 
angles, the hind angles obtuse, the surface sparingly punctured. | 
This species is of rather narrower form than H. alticola, and has joints five to nine 
of the antenne more slender and elongate, and the thorax less transverse. It was 
apparently found by Mr. Champion in the same locality as H. alticola, and was supposed 
by him to be the same species. But it is undoubtedly distinct; for, in addition to the 
differences above indicated, the middle coxe are a little more approximate, so that the 
mesosternal process is rather narrower. A single mutilated individual, in bad condition, 
is all that has been found. 
5. Homalota alticola. 
Nigra, subnitida, capite thoraceque vix subsnescentibus, elytris fuscis; antennis subgracilibus, apieem versus 
paulo latioribus, articulis penultimis leviter transversis; prothorace transversim’ subquadrato, crebre 
punctulato; elytris prothorace longioribus, crebrius punctatis; abdomine segmentis 2°-4™ sparsim, 5° et 6° 
adhuc sparsius punctatis; pedibus sordide testaceis. 
Long. 43 millim. 
Hab. Guarrmata, Totonicapam 8500 to 10,500 feet (Champion). 
Antenne black, conspicuously setose, third joint a little longer than second, fourth 
a good deal longer than broad, tenth slightly transverse. Head rather broad and short, 
sparingly punctate, but little shining. Thorax broad, but a good deal narrower than
