620 STAPHYLINIDA. 
5. Teonodema filiforme. 
Angustius, elongatum, nigrum ; antennarum basi palpisque testaceis ; capite, prothorace elytrisque minus lete 
viridescentibus, densissime fortissimeque punctatis, his punctatura apicem versus parcius ibidemque 
nitidis. 
Long. 9 millim. 
Hab. Panama, Bugaba (Champion). 
Antenne rather slender, very little thicker externally; the five basal joints red, the 
others dark. Head coarsely, very densely punctate. ‘Thorax very slightly longer than 
broad, slightly narrowed behind, remarkable on account of the very dense coarse punc- 
tuation. Elytra elongate and slender, one and a half times as long as thorax, also very 
coarsely punctate, and with a distinct grey pubescence, the interstices slightly shining, 
the punctures on the apical portion much more distant and finer, and the surface there 
more shining. Hind body very slender, the basal segments coarsely punctate, but 
smooth towards the hind margins. 
Unique. I know no species closely allied to this, except the following. 
6. Tenodema tibiale. (Tab. XVI. fig. 12.) 
Angustius, elongatum, nigrum; antennis, palpis tibiisque quatuor anterioribus testaceis, antennis extrorsum 
fuscescentibus ; capite, prothorace elytrisque opacis, minus lete metallescentibus, densissime fortissimeque 
punctatis, his punctatura versus apicem parcius ibidemque nitidis. 
Long. 10 millim. 
Hab. Nicaragua, Chontales (Janson). 
Although very closely allied to 7. filiforme, this insect is readily distinguished by the 
colour of the tibiz; it has also a more convex thorax, with the punctuation rather 
denser and coarser. The sculpture of the elytra is, however, considerably less dense, 
and their pubescence much less conspicuous. 
One example. 
PINOPHILUS. 
Pinophilus, Gravenhorst, Micr. p. 201 (1801) ; Erichson, Gen. et Spec. Staph. p. 669. 
Pityophilus, Brullé, Hist. Nat. Ins. iii. p. 75. 
This genus has a wide distribution even after the subtraction from it of the forms I 
separate under Lathropinus, and occurs in the Old World as well as in the tropical and 
temperate regions of the New World. The species are usually rare, and the number 
extant in collections is probably only sixty or seventy. The genus Arwocerus, Nordm., 
is ascribed to Pinophilus as a synonym by Erichson and others; but this is a mistake, 
as Areocerus is well distinguished by the edentate mandibles; it will probably be 
discovered in our region, as it occurs in South America, and the North-American 
LP. picipes (which has been found near our borders) belongs to it. The Pinophili of 
our region form two very distinct groups, which will ultimately have generic im-
