which is similar to that of the elytra, and by the sparingly punctate hind body; the 
thorax, too, is not only obsoletely but also sparingly punctate, and the punctuation 
of the head is less dense than in the preceding species; the sides of the wing-cases have 
a slightly raised margin proceeding forwards from the hind angle to near the shoulder ; 
but this may possibly be peculiar to the male sex, the only one known to me. 
The example figured is that from Sallé’s collection. The individual sent by My. Flohr 
was probably found at Jalapa. 
4. Misantlius discedens. 
Niger; antennis, palpis tarsisque fusco-rufis ; capite suborbiculari, dense punctato, disco parcius punctato, nitido ; 
prothorace posterius angustato, dense omnium obsoletissime punctulato, pube subtilissima vestito ; elytris 
abdomineque dense subtilissime punctatis. 
Long. 13 millim. 
Hab. Mzxtco, Yolotepec (Salié). 
Antenne elongate and slender, the three basal joints black, the others infuscate- 
yellow ; from joint five to ten each is shorter than the predecessor, the tenth being 
considerably longer than broad, the fifth at least twice as long as broad. Head very 
densely and finely punctured, the punctures becoming rather less fine on the middle 
and also less dense, so as to make a small space shining, the rest of the surface very 
finely pubescent. Thorax narrowed behind, with a very indistinct punctuation and a 
very fine pubescence, the latter so dense as to make the surface dull, which without it 
is shining. Elytra elongate, closely and finely punctate. Hind body slender, also 
densely and finely punctured. 
The male has the front tarsi moderately dilated and a small emargination on the last 
ventral plate. The female is unknown. 
Only a single fragmentary example is known. Though not very similar in appearance 
to the other species of Misantlius it is clear to me that it is really allied to them, though 
it will probably prove distinct enough for a separate genus; but the condition of the 
specimen will not allow a detailed examination. 
PHILONTHUS. 
Philonthus, Curtis, Brit. Ent. t. 610 (1825) ; Er. Gen. et Spec. Staph. p. 426. 
This is a very extensive genus, comprising at present four or five hundred species, and 
is very widely distributed; certain of the species being disseminated by maritime 
commerce are found in various parts of the globe. The European species are numerous, 
and have recently been studied by C. J. Thomson and Cl. Rey, as well as by Fauvel, and 
the result of their studies has been that no European species in which the longer lateral 
seta of the prothorax is distant from the lateral margin remains in the genus. This 
character is certainly one of great importance, for the seta, remaining as a fixed point
