FALAGRIA. 253 
that these corneous plates are not the thoracic side pieces, but a transformation of the 
portion of the prosternum that remains membranous in other Staphylinide. 
I propose also to separate from Falagria those species in which the antecoxal portion 
of the prosternum is very large, the prothorax being elongate and its front margin 
greatly rounded, the legs very elongate, with the hind tarsi very long and slender, the 
basal joint being especially long. This genus, Stenagria, will comprise, besides the 
species here described, F. fawveli, Solsky, F. fovea and F. currar, Sharp. F. curti- 
pennis, Sharp, will have to form a distinct genus from any of the above, as it has the 
hind margin of the mesosternum free, and the postcoxal portion of the prosternum 
entirely membranous. On the other hand, Cardiola, Rey, must be united with 
Falagria, as the characters are not of sufficient importance to justify its separation 
at present. 
Falagria, as thus limited, will still have a very wide distribution in the eastern 
hemisphere, but in the New World is, so far as my collection goes, not existent in 
South America. 
1. Falagria infima. 
Parvula, fusca, parum punctata, sat nitida, pedibus testaceis; antennis haud crassis, articulis penultimis 
transversis ; capite subquadrato; prothorace nitidulo, perparum punctato, posterius leviter angustato, 
dorso profunde canaliculato; scutello obsolete canaliculato ; elytris quadratis, quam prothorax paulo longi- 
oribus, parum punctatis; abdomine crebre subtiliter punctato. 
Long. 2-2} millim. 
Hab. GuaTemMaLa, Guatemala city, San Gerdénimo, Champerico, Zapote, Rio Naranjo 
450 feet, El Reposo 800 feet, Capetillo (Champion).—AntILLES, St. Thomas (ége). 
Antenne rather feeble; third joint distinctly shorter than the second; the four penul- 
timate joints distinctly shorter than broad, the last joint more or less conspicuously 
paler in colour than those preceding. Head shining and impunctate, about as broad 
as the thorax, truncate behind. Thorax small, strongly but not abruptly narrowed 
behind, almost impunctate, with a conspicuous longitudinal channel. Scutellum 
closely punctate, but only obsoletely channelled. Elytra only distantly and indistinctly 
punctate. Basal segments of hind body not crenate at base. 
A single specimen of this obscure insect, from the Island of St. Thomas, was labelled 
in Hége’s collection as /. infima, Fauvel ; and I have adopted this name for the species. 
2. Falagria nitidula. 
Elongata, nitidula, parcissime pubescens, nigra, pedibus antennisque fusco-testaceis, harum articulo basali 
tarsisque testaceis ; prothorace elongato-cordato, profunde canaliculato ; scutello ecanaliculato ; elytris basi 
crebre punctatis ; abdomine perparum punctato. 
Long. 33 millim. 
Hab. Guatemata, El Tumbador 2500 feet (Champion). 
Antenne stout and elongate; the penultimate joints not transverse. Head broad and
