the middle, slightly arcuate, reaching the margin, but never touching the suture; the 
second is a large angular spot with its apex near the suture, and variously clothed with 
the shining silky hairs, but always with a bright spot so covered on the margin. The 
abdomen is pale, the breast pitchy-red. This is the largest species of Epiphleus yet 
described. Mr. Champion captured it in abundance running actively on the bark 
of an immense fallen tree in a clearing of the virgin forest of the low country, and 
in company with very many other interesting Coleoptera; he also observed that it flew 
‘in the hottest sun very actively. Mr. H. W. Bates observed species of this genus in 
the same way on the Amazons, at Ega, running on the bark of felled trees in a curious 
sidelong way, with small Coleoptera in their mouths (Trans. Ent. Soc. 1877, p. 246 ; 
sub Epiphleus chevrolati). . 
Mr. Champion sent home a large series of this species in beautiful condition. 
Epiphleus marginipes (p. 166). 
To the Panama localities given, add:—San Lorenzo, Tolé (Champion). 
I do not think we have sufficient evidence for dividing this species at present ; but 
the examples from the State of Panama certainly at first sight appear very different 
from those from Mexico and other localities in Central and South America with the 
first club-joint of the antenne pale. The species also varies extremely in size: some 
specimens from San Lorenzo being barely four, while others from Tolé are six and a half, 
millimetres long. Neither does the punctuation afford a constant diagnostic. The 
type of EL. terzonatus has the club fuscous, and on closely comparing and re-examining 
it with specimens from Tolé the first club-joint of the antenne appears longer, being as 
long as the funiculus. The problem can only be solved by observation of the living 
insects. Mr. Champion observed them to frequent powdery fungoid growth on the bark 
of fallen forest trees in the “ tierra caliente.”

Plocamocera sericella (p. 168). 
To the localities given, add :—Panama, Bugaba (Champion). 
Mr. Champion met with this species in considerable numbers, running on bark of 
fallen timber in clearings of the forests of the low country, in the hot sun.
