excavation in front of the thorax smaller and more circum- 
scribed than in Dejean% rugosely and finely punctate along its 
median line, and surmounted by a transverse ridge which scarcely 
shows any protuberances ; the rugose furrow near the side deeply 
marked and quite one-third the length of the thorax ; the 
scutellum transverse, depressed, and punctate in the middle ; 
the sculpture of the elytra much as usual in the genus, but 
certainly smoother and more distinctly striate than in the female, 
and more rugose at the apex ; the pygidium less pointed and 
more finely punctate thaA in the female, and not hirsute.'^ 
[Long. 13, lat. 7 lines. 
The following is a description of the female taken from a 
specimen in my own collection ; — 
Reddish-pitchy, the head and prothorax darker, the underside 
clothed as in D, Dejeani ; form extremely robust, moderately 
dilated hindward j clypeus broadly rounded with a strong nearly 
erect reflexed margin ; the head evenly and rather closely 
rugulose, with the clypeal suture very little indicated except at 
its middle, which is marked by a small well-defined tubercle. 
The pro thorax is again as wide as its length down the middle, 
and its base is decidedly more than twice as wide as its front ; 
the anterior angles are rather strongly produced and somewhat 
sharp, the hind angles quite rounded olf, the sides diverging some- 
what straighbly from the front to near the middle, and then gently 
arched (without any sinuation) to the base, which is rather 
strongly lobed in the middle, is finely margined except in its 
middle half, and has an obscure foveate emargination on either 
side ; its surface is finely ^nd thinlv (most finely and thinly in 
the middle of the disc) punctulate ; the furrow within the lateral 
margins deep, wide, and rugose, that within the front margin fine 
and nearly parallel with the front almost to the middle where it 
is suddenly produced backward, so that the space in front of it 
appears as a narrow strip abruptly and triangularly produced back- 
ward at its middle (the apex of the triangular process being 
* I suspect this absence of hairs may be due to abrasion. T.B.
