full-grown larva. It is quite devoid of hairs, cilia, spines, or 
roughened or chitinized areas of any kind. Its skin is micro- 
scopically shagreened. 
ADULT 
The description of the adult is translated from Kerremans’s 
original. 
Endelns bakeri sp. nov. 
Of the group of E. weyersi Rits. and modiglianii Kerrem. related on 
account of the head and prolongation of the ocular tubes [cones] to E. dia- 
bolicus Kerrem., but differing from that species by the elytral impressions 
and by the general coloration. 
Short, pentagonal, entirely more or less bright bronze above; beneath 
almost black. 
Head wide, deeply excavated; eyes protruding very much ectad, emerging 
from short truncated tubes [cones] ; the surface almost glossy and very 
lustrous. Pronotum very much wider than long, short and stout, truncated 
cephalad with the anterior angles sharp and projecting, the sides widely 
arched cephalad and sinuous caudad with the posterior angles obtuse; the 
middle of the disc with two wide transverse carinae. Scutellum small, 
triangular. Elytra short, stout, protruding at the shoulders, sinuous along 
their sides, attenuated caudad, individually widely rounded at their apices 
and minutely denticulated; the surface wavy and unequal, with wide 
lateral and discal impressions which are rounded, except those along the 
suture, on each side of the apex, which are elongated. Beneath smoother 
and more shiny than the elytra. 
Length 3.5-4; width 1.25-1.5 mm. 
Luzon, Los Banos. 
These beautiful little purplish bronze beetles are especially 
noticeable by reason of the prominent, almost stalked eyes and 
the consequent excavation of the front of the head. The elytral 
undulations add to the brilliancy of the metallic color of which 
the legs, especially the femora, partake in a marked degree 
(Plate II, figs. 1, 5, 7, 10). 
They remain for a certain period within the pupal skin after 
having apparently acquired all adult characters, including 
hardening and brilliancy of the integument, and for a some- 
what shorter period in the mine. They fly rapidly, alighting 
after brief flights and running quickly over the leaf. Their 
copulation has not been observed nor has the egg-laying process 
been noted. 
MINES 
The eggshell can always be found at the beginning of the 
mine, v/hich for a distance of 12 to 15 millimeters is narrow, 
usually not over 2 millimeters in width, and follows the leaf 
veins. It may then turn at an obtuse angle, continue for 15
