nearly straight and apparently excavate anteriorly. Elytra not less 
than two and one half times the prothoracic length, apices broken, 
surface finely striate, the striae with distinctly elongate, well-im- 
pressed punctures which are separated in each row by approximately 
their own long diameters, interstitial spaces flat, broad, apparently 
punctate. Abdominal dorsal sculpture, on the portion exposed by 
the spreading of the elytra, obscure. Length, from front of head to 
abdominal apex, 6.70 mm.; of portion of elytron as preserved, 3.60 
mm. 
Described from one specimen.

Since the general preservation of this beetle is poor, I should not 
have ventured to describe it, had not the coxal plate been well shown 
on one side. Taken into account with the form of the prosternal 
sutures, the sculpture and the coloration, this seems to indicate a 
probable affinity with Agriotes. 
LIMONIUS ABORIGINALIS, sp. nov. 
Plate 5, fig. 1-4. 
Form stout for the genus. Head practically smooth. Antennae 
just about reaching the hind prothoracic angles, moderately serrate, 
second and third joints subequal, their united length about the same 
as that of the fourth which, however, is broader and begins the serra- 
tion. Eyes normal. Prothorax about one fourth broader than long, 
not visibly sculptured above, apex scarcely emarginate, narrower than 
the base, sides arcuately broadening to about the middle thence 
slightly sinuately narrowing posteriorly, hind angles well defined, 
acute but not divergent. Scutellum oblong oval. Elytra with sides 
less parallel than in most modern species of Limonius, apices con- 
jointly rounded, surface rather finely but quite distinctly and regu- 
larly striate, strial punctures becoming less distinct posteriorly. 
rounded or slightly oblong, separated by about their own diameters, 
Interstitial areas with signs of fine pubescence. Underside almost 
smooth, only a few small, scattering punctures being visible. Legs not 
displayed. Length, from front of head to elytral apex, 6.65 mm. 
Described from one specimen, with counterpart.
