388 Mr. C. O. Waterhouse on new Lucanotd Coleoptera. 
ornatis; tibiis anticis extus quinquedenticulatis, posticis iner- 
mibus ; corpore subtus sat nitido, rufo-piceo variegato. 
Long. 13 mill., lat. 5, mandib. long. 3. 
The mandibles are a little longer than the head, very 
slightly turned up at the apex ; there is a carina which com- 
mences in the middle of the base, and turning along the outer 
edge terminates in an obtuse scarcely raised tooth a little way 
from the apex; another carina commences at the base near 
the other, and runs along the centre of the mandible to about 
the middle ; the space on the inside of the mandible is thickly 
punctured; there are three or four small obtuse teeth at the 
base. The ocular canthus only encroaches a very little way 
on the eye. There is a slight tumour behind the eyes. The 
sides of the thorax are somewhat parallel, with a very gentle 
sinuosity before the posterior emargination ; the commence- 
ment of the emargination is marked by a distinet slightly 
prominent angle. The anterior and posterior margins are 
impressed ; the disk is moderately thickly and very finely 
punctured. The pale sandy scales, which are generally scat- 
tered over the suiface of the insect, are on the elytra crowded 
together and form a patch below the shoulder, a band rather 
behind the middle (somewhat in the form of a W), and a 
patch at the apex. ‘The underside of the head, the base of 
the femora, and the metasternum are pitchy red, the latter 
shining ; the abdomen is black, rather thickly and moderately 
strongly punctured. 
Hab. Peru, Chanchamayo (Tham). Brit. Mus. 
Scortizus cucullatus, Blanch. 
This species, described originally as a Lucanus, is placed 
by Solier and Burmeister in the genus Sclerostomus, and I see 
no serious objection to its being so placed. The slightly pro- 
duced prosternal process and concave mesosternum agree with 
that genus. Scortizus, on the other hand, has the prosternal 
process more prominent, and the mesosternum is also conically 
produced in front. 
The species appears as a Scortizus apparently first in Major 
Parry’s “Catalogue of Lucanide” (Trans. Ent. Soe. 3rd ser. i. . 
p- 94).
