MYRMEDONIA. 205 
I had examined its structural characters I anticipated it would prove very closely allied 
thereto; but the structure of the sternal pieces and the hind tarsi require that it 
should at present be located in the genus Myrmedonia. Four individuals have been 
found. 
13. Myrmedonia docilis. 
Testacea, capite, elytris abdomineque fuscis, hoc basi elytrisque marginibus basalibus et apicalibus testaceis ; 
capite, thorace elytrisque dense subtilissime punctulatis, abdomine levigato; antennis articulis 7°-10™ 
transversis. 
Long. 3 millim. 
Hab. GuatemMata, Guatemala city (Champion). 
Antenne rather short and stout, with inconspicuous exserted sete, yellow, but rather 
darker in the middle, so as to be there rather red, second and third joints about equal 
in length, sixth about as long as broad, the following decidedly transverse, the tenth 
being nearly twice as broad as long; terminal joint large, three times as long as the 
tenth. Head short and broad, closely and excessively finely punctate and pubescent. 
Thorax nearly as broad as the elytra, strongly transverse, being about twice as broad as 
long, very slightly narrowed behind, the hind angles very obtuse and indistinct, the 
surface closely and extremely finely punctate. Elytra short, but distinctly longer than 
the thorax, fuscous, with the hind margin and a broad humeral spot yellow. Hind 
body with the basal segments yellow, the rest dark, shining, and impunctate. Legs 
clear yellow. 
Three specimens have been found: the structure of the mesosternum and pieces 
round the middle coxe is that characteristic of the genus Myrmedonia; and the hind 
tarsi are very slender, with elongate basal joint, the articulations between the joints 
being, however, very obscure. ‘The facies is suggestive to me of Homalota hospita and 
its allies, for which Rey has established the genus Thamiarea. 
14. Myrmedonia pusilla. 
Nitidula, subtilissime pubescens et punctata, capite abdomineque nigris, hoc basi rufo-testaceo, thorace elytris- 
que fuscis, his humeris dilutioribus; antennis fuscis, basi apiceque sordide testaceis ; pedibus testaceis : 
prothorace valde transverso, fere elytrorum latitudine. 
Long. 3 millim. 
Hab. Panama, Volcan de Chiriqui 2000 to 3000 feet (Champion). 
A small species, bearing a considerable resemblance to the European Homatota fungi. 
Antenne rather short and slender, but little thicker outwardly, third joint longer than 
second, penultimate joints transverse ; terminal joint very long in proportion to the 
others, nearly as long as the three preceding together. Head broad and very short, 
very shining, impunctate, black. Thorax very strongly transverse, twice as broad as 
long, the hind angles very indistinct, the surface shining, with almost invisible punc-
