is, 6 Funkhouser: Philippine Membracidse 681 
gins of mesothorax and metathorax extended to form rough 
toothlike projections. 
Legs moderately foliaceous and flattened; finely pilose and 
closely spined; lighter in color than the rest of the body; tarsi 
ferruginous and finely pilose; claws flavous. 
Undersurface of body very dark brown with white tomentose 
hairs on undersurface of abdomen. 
Length to tips of tegmina, 8 millimeters; width between 
humeral angles, 2.6; maximum width of anterior process, 6.8; 
height of anterior process above head, 5.5. 
Type, a male, in Professor Baker’s collection.

In sending me this specimen, Professor Baker writes: 
I am sending a single unique specimen of the most remarkable of Philip- 
pine Membracidae. It is very strange that it should have taken eight 
years of collecting to produce this one specimen. It only indicates that 
of the great fauna of the high forests we yet know but little. 
It is certainly a remarkable insect and the specific name was 
naturally suggested. 
Genus MESOCENTRUS novum 
Near Cryptaspidia Stal but differing in having four apical 
cells in the hind wing and in having a high central elevation of 
the pronotum, suggesting the genus Telamona of the subfamily 
Smiliinse. 
Tibise simple; hind trochanters unarmed; hind wings with 
four apical areas; tegmina with five apical and three discoidal 
areas; scutellum present but entirely concealed by the prono- 
tum; suprahumeral horns absent; dorsal crest simple, erect, 
without branches or extensions of any kind; posterior process 
heavy, curved, the tip bearing a sharp, narrow, carinate pro- 
jection on the undersurface; head subquadrate; clypeus simple. 
I have never seen a specimen of Melichar’s genus Monocen- 
trus 1 to which this genus is apparently closely related, but ac- 
cording to the description the insects belonging to Monocentrus 
have the pronotal crest branched and the posterior process an- 
gular as in Anchon Buckton. 
Mesocentrus pyramidatus sp. nov. Plate 1, figs. 3 and 4. 
Very dark brown with golden pubescence; pronotal crest 
arising in a pyramid above the humeral angles, this pyramid flat-
