tiliter transversim rugatis; prosterno medio fortius vix 
crebre punctulato, hoc ad latera sulcato, suturis prosternali- 
bus rectis, pronoti margine in prosternum deflexo ; tarsorum 
lamella angusta. 
Maris antennis prothoracis basin vix superantibus ; prothorace 
a basi ad apicem sinuatim angustato. 
Femine antennis prothoracis basin haud attingentibus; prothorace 
ad medium quam trans basin parum angustiori. Long,, 
5—54 1.; lat., 121. 
This species belongs to the third of the groups that I have 
suggested above as convenient subdivisions of Monocrepidius. It 
is remarkable for the extremely close puncturation of its pro- 
thorax. It may be noted that the piece of the prosternum in- 
cluded between the prosternal suture and the margin of the 
pronotum is (not as in some species acuminate, but) obliquely 
truncate in front. In Dr. Candéze’s tabulation of Monocrepidius 
(Mon. II. pp. 191, &c.) the present species would stand beside 
M. fictus, Cand., from which inter alia its considerably larger 
size will distinguish it.

APHILEUS. 
A. ferox, sp. nov. Sat latus ; sat depressus ; fusco-piceus, palpis 
antennis pedibusque testaceis vel piceo-testaceis ; breviter 
cinereo-setulosus ; mandibulis elongatis, quam caput (labro 
excluso) sat longioribus, curvatis, ad apicem acutis (haud 
bidentatis), pone medium intus dente valde elongato arma- 
tis; capite sat nitido inter oculos concavo, sat crebre punc- 
tulato ; prothorace sat nitido, quam longiori tribus partibus 
latiori, obsolete canaliculato, sat crebre (ad latera fere ut 
caput, in medio paullo minus crebre) punctulato, trans basin 
quam trans marginem anticum plus quam dimidia parte 
latiori, subquadrato (sed lateribus versus apicem summum 
fortiter convergentibus, versus basin summam fortiter diver- 
gentibus), lateribus distincte explanatis sed vix manifeste 
marginatis, angulis posticis divergentibus ; elytris striatis, 
striis subtilius punctulatis, interstitiis parum convexis obso- 
lete rugulosis, apice suturali breviter spiniformi. Long. 
(mands. incl.), 18 1; lat., 54 1. 
Larger than A. lucanoides and less widely shaped; differs from 
that species also inter alia by its very distinct mandibles and its 
more nitid prothorax with much closer puncturation. In the 
example before me there is a very conspicuous tubercle on the 
disc of the prothorax a little to the left of the central line, but 
in all probability this is an individual aberration.
