ART. 8. BUPRESTID BEETLES OF MEXICO—FISHER. 45 
uneven and without lateral carina, sparsely and irregularly punc- 
tate, with a very small spot of rather long, recumbent, cinereous 
pubescence at the middle, close to the suture; intervals nearly smooth. 
Abdomen beneath rather flat, sparsely punctate, the punctures large, 
shallow and open on the one side, and from each one arises a short, 
recumbent, cinereous hair; intervals densely and finely granulated; 
last segment broadly rounded at the apex, with the margin cntire. 
Length, 3.75 mm.; width, 2.8 mm. 
Type locahty.— Panama City, Panama. 
Type.—Cat. No. 25110, U.S.N.M. 
Described from a unique female reared from larvae mining in the 
leaves of an unknown plant, the leaves of which are similar to that 
of the rubber plant ( Ficus elastica), and collected by August Busck. 
This species is distinguished from nearly all the other species of 
this genus by being much depressed, nearly glabrous, and the elytra 
without lateral carina. 
The eggs are laid on the upper surface of the leaves, and as many 
as 12 eggs having been layed on a single leaf. The eggs are brown 
in color, strongly flattened, and oval, measuring 2.2 by 1.75 miili- 
meters. The larva on hatching bores directly into the leaf from 
the underside of the egg, and mines under the upper epidermis 
of the leaf. The mines are usually elongate, very irregular, and 
measuring about 12 centimeters in length. At first the mines are 
only 2 millimeters wide, but are gradually broadened until they are 
about 15 millimeters in width. The larva on reaching maturity 
pupates in the leaf without making any cell.

pp. 134-135, pl. 7, fig. 14. 
This species was described from San Geronimo, Guatemala, and 
the type, which is in the British Museum, has not been examined. 
It is the only species known from Mexico and Central America, with 
the exception of fulgidus Fisher, which has no lateral carina on the 
elytra. 
BRACHYS DIMIDIATUS Waterhouse. 
Brachys dimidiatus WaTERHOUSE, Biol. Centr.-Amer. Coleopt., vol. 3, pt. 1, 1889, 
p. 134. 
The type locality of this species is Cerro Zunil, Guatemala, at an 
elevation of 4,000 feet. The type is in the British Museum and has 
not been examined. This is the only known species from the region 
covered by this paper which has the lateral carina interrupted at 
the middle, and is intermediate between the species which have the 
lateral carina on the elytra entire and those without any trace of a 
carina. No specimens have been examined of this species and it is 
placed in the key upon the characters given in the original description.
