200 MADEIRAN COLEOPTERA. 
the females; longitudinally strigulose (especially in the male sex) 
on either side behind; and with its anterior angles (beneath which 
the antenne are inserted) much raised, and rufo-piceous. Prothorax 
and elytra rather deeply punctured, and substrigulose in parts: 
the former rufo-piceous, rounded posteriorly, deeply trisuleated 
down the disk (the outer grooves being but very slightly arcuate, 
and the central one narrowed behind), and widely impressed 
towards either side. Hlytra diluted-testaceous. Mouth rufo- 
piceous. Abdomen almost simple in both sexes. Antenne with their 
four basal joints testaceous. Legs pale testaceous. 
Male, with the head immensely enlarged; its clypeus sinuated in 
front, and triangularly acuminated in the centre; and with the 
mandibles enormously elongated, and acute. 
Female, with the head smaller (and consequently much less deve- 
loped behind the eyes); its clypeus simply rounded anteriorly ; 
and with the mandibles as small as in the ordinary Owyteli. 
Of the present addition to our Catalogue I have had an old speci- 
men long in my possession, given to me by the Rey. R. T. Lowe, and 
taken by the late Dr. Heineken (whose ticket, bearing the manu- 
script name of mandibulatus, is still attached to it); and it was 
through an oversight that it was not included in the Insecta Made- 
rensia, in 1854. It was not however until my visit to the island in 
1855 that I myself succeeded in observing the species in situ,—which 
appears to be tolerably common in and around Funchal, where it 
occurs principally in the dung of cattle, and may be often captured 
on the wing. Like many other insects, it may possibly be an im- 
portation into the Madeiras since the period of their colonization ; 
for, singularly enough, it is recorded, both by Erichson and Manner- 
heim, as a native of America,—having been taken in Columbia and 
Brazil: it has been brought however, likewise, from the island of 
St. Thomas, off the western coast of tropical Africa. 
It may be at once known from the other Oxyteli here enumerated 
by its diluted-testaceous elytra, piceous and posteriorly rounded pro- 
thorax, and by the largely developed head and mandibles (and cen- 
trally acuminated clypeus) of its males.

Inhabits Madeira and Porto Santo; abounding in the former 
island at nearly all altitudes, but being rarer in the latter. In the 
vicinity of the Funchal beach it generally teems.
