Long. 16 mm., lat. 6. 
LUZON, Mount Banahao (8399). 
Elytra with characteristic greenish scale markings as follows: 
Two spots on suture, one in the middle, the other on apex; a 
twice-interrupted subsutural stripe connected behind with a sim- 
ilar marginal stripe; disk with two oblong spots, one before, the 
other behind the middle; submarginal stripe abbreviated on base 
and at apex. In other respects it is very similar to P. psittacinus, 
from which it differs in having the dorsal impression on rostrum 
well defined, transverse oval, unscaled, and head and prothorax 
almost imperceptibly remotely punctate. In my single specimen 
of P. psittacinus the triangular, laterally and posteriorly shal- 
low, dorsal impression on rostrum shows the front margin on 
both sides slightly emarginate and, therefore, the apical part of 
rostrum feebly bilobed dorsally. 
Pachyrrhynchus modestior Behrens var. transversatus var. nov., ¢. 
A specie typica differt: vittis pallide chloro-squamosis in tho- 
race fascia antemediana, in elytris fascia submediana, ad suturam 
vix interrupta, conjunctis. :

Like P. inclytus Pasc. this remarkable form, with a crossband 
before the middle of thorax and another very near the middle of 
elytra, represents only a variety, hardly a local race, of P. modes- 
tior Behrens. I have not seen it from any other locality than 
Imugan. 
Pachyrrhynchus rugicollis Waterh. var. aurinius var. nov. 
A specie typica differt: squamulis rosaceo-margaritaceis in 
loco malchiticis ornatus. , 
LUZON, Zambales Province, Iba. 
As I have enumerated P. rugicollis Waterh. in my key of 
-Pachyrrhynchug species ** as a green-scaled, mountain species, 
attention may be drawn to this variety with scales of a rose 
pearl-shell luster, 
Macrocyrtus pseudopolitus sp. nov., ¢. 
Nigro-nitidissimus, M. negrito Heller subsimilis sed minor, 
elytris ante apicem, corpore subter macularum viridi-squamos- 
arum rudimentis; rostro impressione sulcoque mediano dorsal- 
ibus; prothorace latitudine longiore, lateribus perpaulo rotun- 
datis, subparallelis, vix perspicue vageque punctato; elytris
