XXXIV. CERCERIS. 237 
on each side of the second, third, and fourth segments (some- 
times wanting); the intermediate carinz of the anal segment 
parallel, and the surface between them punctured and opaque ¢. 
The ¢ differs in having the lateral lobes of the clypeus with a 
rigid fringe of golden sete, and the central one obsoletely 
trifid; all the joints of the antenne ferruginous beneath, ex- 
cepting the scape, which is yellow, and the apical joints entirely 
ferruginous; the face below the antennz yellow, as well as on 
each side at the inner orbits of the eyes extending half-way to the 
vertex; the clypeus entirely yellow; the yellow spot behind 
the eyes, and the spot on each side of the metathorax, wanting ; 
the tegulz yellow; the coxe with yellow markings, and the base 
of the posterior femora not black, but with black spots towards 
the apex within; the abdomen with a narrow band on each of 
the segments, excepting the first, which has a small yellow spot 
on each side, the bands of the rest much attenuated in the 
middle, and the penultimate ventral segment with a strong denti- 
form process on each side.

44+ Never having been fortunate enough to fall in with 
this species, I do not possess a specimen, much less a series, 
by which alone it is possible to determine any insect’s 
range of variation. It is extremely like the following, the 
$ especially; and this sex appears to want a sufficient 
character to separate it from the same sex of the follow- 
ing, which I have no doubt would present itself. The ¢ 
seems to be distinguishable from the following, solely by 
the superior elevation of the central lobe of the clypeus, 
which is entirely raised up and holds only by its base. It 
is also generally larger than the largest I have ever met 
with of the following species. I cannot ascertain its dis- 
tinct locality.
