DESCRIPTION OF A NEW STAPHYLINID BEETLE FROM MACQUARIE 
ISLAND. 
By A. M. Lea, F.E.S., South Australian Museum, Adelaide. 
HOMALIUM VARIIPENNE, 1.Sp. 
Piceous-brown; six basal joints of antenne, palpi, and legs more or less flavous; 
elytra varying from entirely dark to almost entirely flavous. Head, prothorax, and 
elytra with a few short, erect sete, upper surface of abdomen with short and not very 
dense, ashen pubescence, almost absent along middle; under surface more sparsely 
clothed, the sterna more sparsely than the abdomen. 
Head (excluding neck) sub-triangular; with two small deep fovez between eyes, 
and a shallow depression near each antenne; surface finely shagreened and minutely 
punctate. Antenne passing middle coxex; first joint rather stout, as long as second 
and third combined, second and fourth sub-equal in length, and distinctly shorter than 
third, sixth—tenth equal, distinctly wider than the four preceding ones, eleventh about 
once and one-half the length of tenth. Prothorax rather strongly transverse, widest 
near apex, sides rounded in front, oblique to base; with a conspicuous but shallow 
longitudinal depression on each side of the middle, the depressions more opaque than the 
adjacent surface; two small foves at apex immediately behind those on head; surface 
finely shagreened, and with numerous small punctures. Elytra almost as long as head 
and prothorax combined, base much wider than base of prothorax, hind angles widely 
rounded off; with small, dense, sharply defined punctures. Abdomen elongate, 
shagreened and with small dense punctures; margins slightly wider than scuttellum. 
Legs moderately long, length to apex of elytra 23, of abdomen, 4} mm. 
Halitat.—Macquarie Island. 
The sete on the upper surface, although erect, are so short and sparse that they 
could easily escape notice; in some lights, the abdominal pubescence has an almost 
golden gloss. Of the five specimens before me, two have a large flavous spot on each 
shoulder; each spot on the outside extends to the margin, on the inside about half-way 
to the suture, and posteriorly to about one-third from the apex; on a third specimen, 
the spots are similar in size, but vaguely indicated; on a fourth, the elytra are flavous, 
except for a narrow infuscation of the suture, and for a rather narrow apical border
