Agbalus viridis, sp. nov. . 
Medium sized. Below, rather dark, blackish green; above, 
shining, neous green metallic; thorax narrow in front, minutely 
~punctured; elytra elongate, closely punctate in regular striae; ¢ 
with a thorn-like prolongation near the apex of the hind femora. 
Type, 3 g, 2, Costa Rica (Biolley). , 
Length, 5 mm. 
Head with a few fine punctures, and with the ordinary 
transverse and longitudinal grooves; labrum fulvous; antenna 
with four or five basal joints fulvous, remainder dark; thorax 
strongly narrowed in front, sides feebly rounded and narrowly 
margined (like chiriquensis, Jac.); surface finely punctured ; 
elytra elongate, with shallow transverse depression, closely and 
strongly striate punctate, coarser at the base and sides; legs with 
tibia and tarsi more or less rufescent. 
This form is nearly related to chiriquensis, Jac., and of the 
same narrow elongate shape, and forms the northern represen- 
tative of the group composed of subcostatus, Jac., and bolivianus, 
Jac. This last species is described by Mr. Jacoby, as above, 
metallic greenish, and with fulvous legs. Forms occur with legs 
nearly dark, and also with the upper surface blue or purple, all 
from the same locality; I regard them all as varieties of 
bolivianus. 
Alethaxius carinipennis, sp. Nov. 2 
Size large, elongate, parallel. 2 broadened; in ¢ dark, shining, 
metallic eneous green; head coarsely, aciculate punctate, sparse at 
the vertex ; thorax rather sparsely punctured, with large and small 
punctures mixed; elytra strongly, almost regularly seriate punctate, _ 
the humeral interval in the ¢ developing into a strong carina, 
extending from almost the middle nearly to the apex; Q has this 
carina replaced by a more or less double row of strong rugosities, 
which begin with the shoulder and extend to the apical third; legs 
rufous, more or less cyaneous. ; 
Type, 3 ¢,2 9, Equateur. 
Length, 5°5-7 mm. 
The head has a deep triangular fovea on the front, between 
the eyes; apex pointing backwards, the sides forming a fairly 
well-defined carina, running to the base of the antenne ; the 
labrum is rufouscyaneous. Antenne extend to the middle of the 
elytra, dark, with the lower joints more or less rufous, scarcely 
thickened at the end; thorax wide, strongly margined, and 
bisinuate at the middle; the punctuation is rather sparser and
