330 STAPHYLINIDA. 
Head orbicular; antenne with the three basal joints yellow, the others dark, the 
penultimate joints slightly transverse; palpi fuscous. Thorax broader than long. 
Flytra a little longer than the thorax, of a pale brownish colour, broadly dark about 
the suture, finely and rather closely punctate; scutellum closely punctate. Hind body 
rather sparingly punctate; the hind margin of the penultimate segment rather broadly 
red, the following segment red with a black patch on the middle; terminal styles red, 
fuscous towards the extremity. 
Four individuals have been found; the one figured is from San Gerénimo. 
4. Quedius illatus. 
Parvus, niger; antennarum basi pedibusque testaceis, elytris rufo-brunneis; abdomine versicolore, segmentis 
apicalibus margine posteriore rufescente, crebrius punctato. 
Long. 6 millim. 
Hab. Mexico (Flohr), Jalapa (Hoge); Guaremata, Sinanja in Vera Paz; Panama, 
Volcan de Chiriqui up to 4000 feet (Champion). 
Antenne scarcely thicker externally; the three basal joints red, the others darker ; 
tenth joint as long as broad. Head orbicular. Thorax short, much broader than long, 
much narrowed in front, like the head shining black. Scutellum densely punctate ; 
elytra of a dark red colour, closely and finely punctate. Hind body strongly metallic, 
with purplish or iridescent reflections, closely punctured, and with much black pubes- 
cence; the hind margin of the penultimate segment lurid red or yellow, the terminal 
segment with this colour more extensive on the hind margin; terminal styles red, with 
long, dense, black pubescence. 
Although widely distributed, this is apparently not a common species, as I have seen 
altogether only ten individuals. The specimens from Mexico and Guatemala have the 
legs nearly black, but do not apparently differ in other respects. 
§ 3. Gene with a raised margin; elytra polished, with only a few setigerous punctures, 
which are arranged in a serial manner, and in addition with a very regular series 
of conspicuous punctures contiguous with the epipleural margin. 
5. Quedius basiventris. (Tab. VIII. fig. 5.) 
Rufo-testaceus, politus, nitidissimus ; capite abdominisque segmentis duobus basalibus nigris ; elytris sublevi- 
gatis punctis nonnullis setigeris subobsoletis impressis, abdomine parce punctato. 
Long. 7-8 millim, 
Hab. GuatemMALa, Volcan de Atitlan about 3000 feet, Mirandilla 1700 feet, Las 
Mercedes, Pantaleon, San Isidro (Champion); Panama, Volcan de Chiriqui between 
2500 and 4000 feet (Champion). 
Antenne yellow, a little thicker towards the extremity, the three or four penultimate 
joints a little subserrate internally. Head orbiculate, but a good deal narrower than
