sparingly punctate, the punctures coarser on the middle than at the sides, the colour 
castaneous yellow, black along the middle. Elytra longer than the thorax, rather 
closely and moderately finely punctate, broadly black at the outer angle; hind margin 
scarcely sinuate. Hind body flat, shining, regularly moderately closely punctate, the 
two or three apical segments more or less marked with black on the middle. Legs 
stout, yellow, the tibie more obscure in colour than the femora, and the tarsi still 
darker, so as to be piceous. 
Three individuals have been found; they all have the dorsal plates of the sixth 
- and seventh segments granulate, and the rather narrow hind margin of the seventh 
truncate ; I think they are females. 
MYLLABSNA. 
Myllena, Erichson, Kaf. Mark Brand. i. p. 382. 
About twenty-five species are at present comprised in this genus, which, like so 
many others of those at present accepted in the Staphylinide, has a very wide distribu- 
tion, species occurring even in the Sandwich Islands. It is one of the most difficult of 
all the genera of the family to deal with, owing to the great resemblance of the species 
and the absence of any important sexual or structural characters to distinguish them. 
The habits of these creatures, which run swiftly in muddy places or live amongst 
damp moss, render it certain they are not artificially distributed. 
1. Myllzna mollis. 
Densissime subtilissimeque punctulata, brevissimeque sericeo-pubescens, subopaca, fusca, prothorace dilutiore, 
pedibus palpisque dilute testaceis; antennis articulis basali et apicali testaceis, gracilibus sed parum 
elongatis. 
Long. circiter 2} millim. 
Hab. GuatTema.a, near the city (Champion). 
Antenne longer than head and thorax; first joint very short, half as long as the 
second ; third rather more slender and shorter than second ; fifth to tenth differing but 
little from one another, each very distinctly longer than broad; tenth paler than those 
preceding it. Thorax evidently paler in colour than the elytra, the base truncate, just 
perceptibly sinuate on each side near the hind angles. Elytra scarcely longer than the 
thorax. Hind body more or less distinctly testaceous behind. Legs stout, clear 
yellow. 
_ _This species is very similar to the European I. intermedia, and the individuals of 
the two species are of about the same size; J. mollis is, however, rather the more 
fragile and is paler in colour, its antenne are evidently shorter, as are also the legs. 
Two typical individuals have been found ; a third, from the same locality, of rather 
more slender form and darker colour, also probably pertains to the same species. An
