138. BOLBOCERi^.S INGENS, n.sp. 
Of a chestnut colour, nearly black on the head and thorax, rather 
nitid. Head densely and rugosely punctate, rising into a broad 
strong projecting and slightly recurved horn at the apex of the 
clypeus, and vertical and slightly retuse on the forehead. 
Thorax three times wider than long, deeply emarginate at the 
apex, enclosing the head to the middle of the eyes, much 
ampliated and rounded to the base, which is broadly rounded, the 
sides densely ciliated and crenulate, the anterior portion of the disk 
vertically retuse showing three excavated and smooth surfaces — the 
middle one of crescentic form, with a prominent protuberance on 
each side, the others more profoundly excavated, the rest of the disk 
largely and coarsely punctate. Elytra not so wide as the thorax 
and much wider than long, emarginate at the base, rounded on the 
the sides and apex, and 14 punctate-striate. Beneath very hairy; 
anterior tibiai 5-dentate. One male specimen.

139. Bolboceras cornutum, n.sp. 
Piceous-red, nitid. Head small, densely punctate, the vertex 
raised into a long straight rather obtusely pointed horn, with the 
ti'ansverse raised line Vjetween the eyes truncate in the middle. 
Thorax about twice as wide as long, the sides moderately ciliated, 
not serrated, and much bulged out towards the posterior angles ; 
the base broadly rounded, a large transversely rounded smooth 
hollowed-out space occupying the middle of the disk, with a 
strong compressed tubercle on each side of it, and a large patch 
of rough large punctures between the hollowed-out space and the 
sides, the rest of the disk smooth. Elytra much narrower and 
little longer than the thorax, finely striate-punctate. The female 
has, instead of the horn, a small bifid tubercle on the forehead and 
no tubercle on the thorax. 
Long. 8, lat. 5 lines.
