ICHNEA.—APOLOPHA. 181 
b. Antenne apparently ten-jointed. 
7. Ichnea aterrima. 
Ichnea aterrima, Klug, Gemm. & Har. Cat. Col. p. 1751"; Sallé coll.

Hab. Muxico1?, Guanajuato (Dugeés, coll. Sallé). 
The species thus labelled in Sallé’s collection has very much the appearance of an 
Epiclines such as E. basalis, but in the structure of the antenne shows a clear affinity to 
Ichnea. The palpi are cylindric and truncate, as in that genus; but the prothorax 
exhibits a marked distinction in having sharply defined lateral margins and certain 
ill-defined longitudinal ridges and sulci. The elytra are opaque dull black, very finely 
punctured, and coriaceous. ; 
I think it will be eventually separated with the species which follows, which is closely 
allied to it, to form a new genus. 
8. Ichnea dugesi. _ 
Atra, opaca, subtilissime punctata, prothorace subquadrato, lateribus et infra saturate rufis; elytris modice 
dilatatis, sutura paullulum elevata. Long. 7-8 millim. 
Hab. Mexico, Guanajuato (Dugés, coll. Sailé). 
Very closely allied to the preceding species, and hardly to be distinguished from it 
except by the colour of the thorax. The head is rough and opaque, the antenne and 
palpi black: of the antenne the intermediate joints (that is, the third to seventh) are 
obconic, hairy on their inner edge, but quite distinct; the eighth and ninth expanded, 
and nearly as long as the part of the antenne preceding them; the tenth elongate, 
sinuate on its inner margin, nearly as long as the two before it. The thorax is as wide 
as long, with the sides a little expanded, but without any trace of tubercle; each side 
of the disk is impressed with a broad shallow depression ; the edge is sharply margined, 
the margin extending round the base ; constricted lines are not present. The underside 
is shining black. ‘There are five specimens in Sallé’s collection. 
APOLOPHA. 
Apolopha, Spinola, Mon. i. p. 881; Lac. Gen. des Col. iv. p. 482.. 
The association of the three species here given with Spinola’s genus is doubtful ; for 
there is a discrepancy between his description of the number of joints in the antenne 
and the number shown in the plate (t. 36. f. 1). Hight is the number he names, and 
that is the number I count in my species ; but, owing to the intermediate joints being 
hairy on the inner side and reduced in length, it is probable that the rudiments of one 
or two more are present. There is an obvious affinity to Jchnea in the structure of 
these organs.
