_ and two oblique, rather curved stripes formed of dense white hairs: the 
elytra have several rows of punctures, with the interstices minutely granu- 
lated ; each elytrum has a discoidal white dot a little below the middle, 
and, in several specimens, there is also an indistinct one between it and 
the apex : on each side of the abdomen underneath, as in Z. arcticus, are 
four yellowish round spots formed of hairs. In some specimens the 
pubescence has a tawny hue, in others the indistinct spot is obliterated.

body 714 lines. A single specimen taken in Lat. 65°. 
Body very black, covered more or less with decumbent white hairs, 
and also with minute tubercles. Rostrum as in Z. Colon: prothorax 
ridged, confluently tuberculated, minutely punctured between the tuber- 
cles, marked on each side with an oblique stripe composed of white hairs: 
elytra confluently tuberculated, with five pairs of longitudinal streaks, 
converging towards the apex: the first and fifth including the rest.

Several specimens taken in the Expedition. a 
Body narrow, black, covered with decumbent hoary pile. Head 
thickly covered with hairs, but on each side from the eye to the insertion 
of the antennae, the hairs are less dense, which gives the appearance of 
a blackish stripe ; rostrum thick, shorter than the prothorax, obsoletely 
ridged, punctured: prothorax obsoletely ridged, punctured with rather 
large scattered punctures, often concealed by the hairs, with three blackish 
stripes, produced as in the head by the hairs being thinner: the elytra 
also have three similar stripes, and are punctured in rows: the abdomen 
underneath appears as if dotted with black from the same cause. 
ZOOLOGICAL PARALLELISM. 
BY PROF. JAMES T. BELL, BELLEVILLE. 
In making a general survey of the Animal Kingdom, it is impossible 
to avoid being struck by the remarkable parallelism which exists between 
the several orders and families, and even genera and species, that com- 
pose the respective classes into which it is divided, and which reveals 
itself in the representative types that abound throughout its whole extent.
