ESSOLITHNA PLUVIATA, Pasc. 
2 
All the species I have under examination are much smaller 
than the size ascribed to this species (4 lines), the largest 
being less than З lines. | 
ESSOLITHNA кһомвоѕ, Pasc. 
Four specimens under examination possibly belong to this 
species; they differ from Mr. Pascoe's description in having 
punctate granules and the elytral interstices convex. They 
are from Champion Bay, and vary in length from 1% to 24 
lines. The species differs from seriata (which it much re- 
sembles) in being smaller, with a shorter scape, basal joints 
of funicle differently proportioned and elytral suture thick- 
enéd posteriorly. 
PEPHRICUS ECHIMYS, Pasc. 
I have three specimens under examination, which I believe 
belong to this species. The base of the rostrum, however, is 
distinctly transversely impressed: a character not mentioned 
by Mr. Pascoe. The species must be very close to Poly- 
phrades cinereus, but the elytral suture of that species is de- 
scribed as subcarinate towards apex; from P. murinus and 
perignarus it may be distinguished by the long elytral sete. 
PEPHRICUS NANUS, Blackb. 
Three specimens (from Swan River) probably belong to 
this species. They vary in length from 1} to 14 lines. One 
of them is without pale markings; two of them have a mode- 
rately distinct spot on each side at base of elytra (as men- 
tioned by Mr. Blackburn); and one has in addition a dis- 
tinct lateral stripe on the prothorax. The vostrum is as 
described.
