of netu genera and species of Tenebrionidce. 349 
long as wide, a little narrower, and more thickly mar- 
gined at apex than at base ; apex strongly emarginate, 
the angles prominent, acute, directed forwards ; sides feebly 
rounded ; hind angles acute, directed behind, and reposing 
on the shoulders of the elytra ; base emarginate, slightly 
sinuously sloping at each side from the middle of the 
margin to the hind angles ; lateral margins reflexed, 
thickened, rather strongly crenate in the middle, broadly 
channelled within ; scutellum strongly transverse : elytra 
obovate, middle of base emarginate, this — with the emar- 
gination of the base of prothorax — leaves exposed the 
scutum of the mesothorax ; lateral margins very narrow, 
slightly reflexed, a little sinuous behind the shoulders and 
near the apex : epipleural fold narrower than in Nycto- 
zoilus, entire : prosternum convex, longer than in Nycto- 
zoilus ; its process robust, subhorizontal, broadly margined 
at each side, prominent and narrowly rounded behind: 
riieso sternum subvertical, and deeply concave, in front, its 
epimera posterior: metasternum — between the coxje — as 
long as the 2nd ventral segment : intercoxal process wide, 
broadly rounded infr^ont: 1st and 2nd ventral segments 
slightly emarginate — and narrowly coriaceous — in the 
middle behind, the 3rd and 4th sinuously emarginate, and 
broadly coriaceous behind : legs rather long, slender ; 
femora feebly claviform ; tihi<s sublinear, feebly spurred, 
the intermediate very slightly bowed, the posterior with a 
fine tomentose line down the apical half within : tarsi 
elongate, slender, pilose and channelled beneath, the joints 
of the anterior not imbricated ; the first of the posterior 
nearly as long as the 3 following united. Body very 
elongate-ovate, convex; elytra strongly, and somewhat 
reticulately, costate. 
I may be wrong in placing this genus near to Nycto- 
zoilus, the likeness to that genus not being at all striking. 
I think, however, that the form of head, the thickened 
edges, and expanded — or broadly guttered — sides of pro- 
thorax, the strongly transverse scutellum, the very convex 
prosternum, and the broad intercoxal process, warrant me 
in so doing. I have but little doubt that the species is 
the same as that described by Macleay (Trans. Ent. Soc. 
N. S. Wales, 1872, p. 284) under the name of Nyctozoilus 
elongatulus. To avoid confusion (and as one can never 
be quite certain in these matters without absolute com- 
parison of specimens), I shall give my species the same 
specific title.
