200 STAPHYLINIDZ. 
I have seen, besides those sent me by M. Fauvel, is an individual found by Hoge; it 
agrees exactly with the North-American examples. 
2. Myrmedonia flavicornis. (Tab. V. fig. 17.) 
Myrmedonia flavicornis, Solsky, Bull. Mosc. xli. p. 258°. 
Hab. Muxico!, Jalapa (Flohr and Hoge), Cordova (Sallé); GuaTreMaLa, Guatemala 
city and San Gerénimo, El Reposo 800 feet (Champion); Nicaragua, Chontales 
(Janson). 
This species varies a good deal in colour, the head and thorax being sometimes 
fuscous, sometimes nearly red; the yellow marks on the hind body vary greatly in 
extent. The species is very closely allied to I. fawveli, and the pale individuals are 
extremely similar to that species; but MW. flavicornis is rather larger, and has the 
antenne rather stouter towards the apex, so that the penultimate joint is a little 
transverse ; and the middle and hind femora are always broadly infuscate towards the 
extremity. 
Although the species is rather widely distributed, the individuals that have been 
found are but few in number. 
3. Myrmedonia confinis. 
Gracilis, fusca, nitidula, antennis extrorsum, pedibus, elytrorum humero et margine apicali abdominisque 
segmentis basalibus postice testaceis; capite, thorace elytrisque parce subtilius punctulatis, abdomine 
leevigato. 
Long. 34 millim. 
Hab. Guatremaua, Paso Antonio 400 feet (Champion). 
Antenne dark at the base, becoming yellow towards the extremity, a good deal 
thickened outwardly, the penultimate three joints very decidedly transverse. 
This species is very closely allied to WZ. flavicornis; but the colour is more obscure, 
and the base of the antenne is dark, and the terminal joints of the antennz are less 
elongate. ‘The punctuation of the head, thorax, and elytra is rather less indistinct. 
I have seen four individuals, in very decayed condition. 
4. Myrmedonia setigera. 
Testacea, nitidula, parcius subtilissime punctulata, setulis erectis nigris minus parce munita, elytris fuscis 
humeris margineque apicali testaceis ; abdomine fusco, segmentis basalibus testaceo marginatis. 
Long. 37 millim. 
Hab. GuaTEMALA, Zapote (Champion). 
Antenne elongate, compact, third joint conspicuously longer than second, penul- 
timate about as long as broad. Head. very short and transverse. Thorax rather 
strongly transverse, not much narrowed behind. Elytra but little longer than the 
thorax.
