MYRMEDONIA. 203 
this may be the result of decay, or of a different condition of maturity, it leaves some 
doubt whether the two individuals are certainly one species. 
9. Myrmedonia plebeia. 
Pallide fusca, antennis nigris, harum basi, pedibus, elytrorum humeris abdomineque basi testaceis, femoribus 
posterioribus extrorsum fuscis; prothorace fortiter transverso, parce subtiliter punctato ; elytris quam 
hic paulo longioribus, vix erebrius punctatis, abdomine supra levigato. 
Long. vix 3 millim. 
Hab. Guatemana, San Joaquin in Vera Paz (Champion). 
Quite similar to MW. laxicornis, but smaller, and with the thorax still more strongly 
transverse, and the antenne a little shorter, so that the penultimate joint is distinctly 
transverse. 
In the male the dorsal plate of the terminal segment is truncate and obscurely 
crenulate, and the outer angles are very slightly more prominent. 
Six individuals of this species have been found. They are apparently all rather 
immature; and the femora vary a little in colour, probably in consequence of this. 
10. Myrmedonia filicornis. 
Fusca, antennis pedibusque testaceis, abdomine nigro ; sat crebre subtiliter punctulata, ad latera setis exsertis 
conspicuis, abdomine supra levigato. 
Long. circiter 34 millim. 
Hab. Guatemaua, Aceituno (Champion). 
Antenne elongate and slender, very little thickened towards the extremity, entirely 
yellow; third joint slightly longer than second, tenth longer than broad; terminal 
joint very elongate, quite as long as the two preceding together. Head short and 
broad, rather convex, feebly punctulate, shining. ‘Thorax strongly transverse, but 
little narrowed behind, the hind angles rounded, the surface rather convex, finely 
punctulate, towards the sides with conspicuous erect black sete. Elytra longer than 
the thorax, fuscous, with an indistinct yellow spot at the shoulder, very finely and 
rather closely punctulate, with conspicuous lateral sete. Hind body black, shining, 
impunctate. Legs very slender, yellow. 
This species, of which I have only a single badly preserved individual for exami- 
nation, is remarkable by the elongate slender antenne, which also become but little 
thickened outwardly. The metasternal process is much produced between the middle 
legs, but is rather ill-defined, owing to its raised margin being extremely fine; the 
intercoxal isthmus is slightly longer than it isin J. laxicornis. The aspect of the 
species is different from the other Myrmedonie here described, and approximates to 
that of the group of Homalote containing H. fungi. 
11. Myrmedonia homalotoides. 
Antennis laxe articulatis, nigris, basi fusco-testacea ; capite thoraceque nigro-subenescentibus, hoe fortiter
