242 STAPHYLINIDA. 
constricted at the vertex. Thorax transversely subquadrate, very densely and finely 
punctulate. Hind body parallel, closely punctate. 
The form of the head readily distinguishes this very minute insect from H. minuta. 
Only two specimens have been found. 
5. Epipeda brevicornis. 
Angustula, dense subtilissime punctulata, opaca, abdomine ad apicem nitido, fusco-rufa; antennarum basi, 
elytris pedibusque testaceis ; antennis brevibus ; capite sat elongato, pone oculos subangustato. 
Long. 1% millim. 
Hab. Guatemaa, Zapote (Champion). 
Antenne short, rather stout; third joint small, much shorter than the second ; fourth 
quite small, transverse; fifth to tenth similar to one another, each rather strongly trans- 
verse; terminal joint small. Head rather elongate and narrow, flat, slightly narrowed 
behind the rather large and prominent eyes, very densely punctate, dull. Thorax nearly 
as long as broad, a little narrowed behind, but with the hind angles distinct, a little 
depressed longitudinally along the middle, excessively densely and finely punctate, quite 
dull. Elytra densely and finely punctate, longer than the thorax. Hind body elongate 
and narrow, the basal segments densely punctate, the apical ones impunctate. 
Of this very minute insect only a single example has been found; it has three 
elevated granules near the hind margin of the sixth dorsal plate, and is probably a 
male; the seventh segment cannot be seen. The number of joints in the tarsi has not 
been ascertained ; the middle coxe are nearly but not quite contiguous. 
6. Epipeda delicatula. 
Angustula, sat elongata, parum depressa, omnino dense subtilissimeque punctulata, peropaca, fusca; antennis 
fusco-testaceis ; pedibus testaceis ; capite minore, subrotundato. 
Long. 13 millim. 
Hab. GuatemMaa, Zapote (Champion). 
Antenne not elongate, and only moderately stout; third joint small, much shorter 
than second ; fourth small, not so long as broad ; fifth to tenth transverse; terminal 
joint short, stout and obtuse. Head rather narrower than the thorax: this latter 
transversely subquadrate, straight at the sides, with the hind angles distinct ; the sur- 
face even, without depressions, rather convex, like the head excessively densely and 
finely punctate, quite dull. Elytra elongate, longer than the thorax, very densely and 
finely punctate, quite dull. Hind body narrow and elongate, very densely and evenly 
punctate, dull. . 
This extremely minute insect has a very Trogophloeoid appearance ; the middle cox 
are rather widely separated ; and, so far as I can judge, it is really congeneric with 
E. rufa. Only one specimen has been found. "
