This is a very distinct species, and may be hereafter con- 
sidered to be generically distinct from P. sex-notata.

This little species belongs to my fourth section of the 
genus (Longic. Malayana, p. 174), characterized by the basal 
crests and by the gradually declivous posterior portion of the 
elytra; but it differs from every other species of the section 
in the presence of two well-marked tubercles on the prothorax. 
In so large a genus, where the coloration is confined to various 
shades of brown with obscure or indefinite spots or markings 
ot greyish or whitish (and even in individuals of the same 
species there is sometimes a considerable modification caused 
by the predominance of one or the other of these colours), it 
becomes very difficult to give an accurate idea of the characters 
in these respects: in the specimen before me there are two 
or three concentric black and white lines on the posterior half 
of the elytra, the innermost black line at its commencement 
anteriorly marking the position of the postmedian crest (or 
tubercle). I owe my examples to the well-known polyglot 
president of the Entomological Society of Stettin, after whom 
T have named it *.

* Dr. Gerstacker (‘Die Gliederthier-Fauna des Sansibar-Gebietes,’ 
p. 261) enumerates P. melanura, a Malayan species, among the insects 
of Zanzibar. His Phoryctus mucoreus is evidently Enaretta Castelnaudi, 
Thoms. ; and his Rhopalizus sansabaricus is a Callichroma.
