NEW PHYTOPHAGOUS COLEOPTERA 53 
¢. Antennae with the third, fourth and fifth joints triangu- 
larly dilated. — 
2. Antennae normal. 
Length 3-4 lines. 
o. Head impunctate with a strongly raised tubercle near the 
inner margin of the eyes; labrum and jaws testaceous; antennae 
entirely fulvous, the second joint very small, the 3. following 
of nearly equal length and especially the 3.%, 4.” and 5." joints 
strongly triangularly dilated, the rest elongate, slender and of 
equal length; thorax with a few scarcely visible punctures, the 
transverse groove moderately deep, the sides rounded in front 
of the middle; scutellum fulvous; elytra extremely finely and 
not very closely punctured, the transverse fulvous band gene- 
rally extending to the lateral margin and slightly widened near 
the suture, of variable length, the extreme apex of each elytron 
sometimes with another small fulvous spot; underside fulvous, 
the tibiae and tarsi generally darker, sometimes the posterior 
legs black; pygidium testaceous. 
Hab. New Guinea, Fly River, Katau (L. M. D'Albertis) Ramoi 
(Beccari). | 
At first sight this species may be confounded with A. dorsalis 
or A. affinis but the entirely fulvous head, similarly coloured 
antennae and the structure of the latter in the male insect 
together with the testaceous pygidium will prevent the species 
to be mistaken for any other; the eight specimens before me 
I am perfectly able to separate from their allies, as the characters 
pointed out seem to be constant in these several closely allied 
forms. 
20. Aulacophora austrocaledonica, Montr. 
Specimens obtained at the Fly River, in the Aru Islands 
and at Buru agree very nearly with the description given by 
the author, but differ in the black breast and often in the de- 
sign of the elytra in which the black portion predominates and 
is divided by a narrow testaceous transverse band at the middle,
