antenne, has four or five longitudinal coste at the sides of the elytra. Specimens of 
the two sexes were captured in about equal numbers. 
AGBALUS (p. 123). 
The type of this genus (A. sericeus) has short, robust antenne and legs, but several 
of the species placed in it by Lefévre (including A. chalybeus) possess long, filiform 
antennee and slender legs. |

Many examples of A. chalybeus were obtained by Mr. Champion; it is evidently a 
very variable insect. The typical form, specimens of which from Panama M. Lefévre 
has kindly examined, is of a dark blue colour above; the punctuation of the thorax is 
fine, and that of the elytra strong and arranged in close rows. Other specimens, also 
from the State of Panama, are much more finely punctured, and have the thorax more 
rounded at the sides, and the antenne pale; some of these have dark fulvous legs. 
Besides these varieties, two others are before me, one of them of a greenish-eneous or 
bronze colour, the other metallic cupreous, the legs being either neous or fulvous. I 
am unable to satisfactorily separate these forms, although they differ a little in shape 
and punctuation, as well as in size and colour. The males of all of them have the usual 
characteristic long spine to the posterior tibie. 
4, Agbalus puncticollis. 
Broadly ovate, black; above dark violaceous; the basal joints of the antenne fulvous; thorax closely and 
evenly punctured, the punctures elongate in shape; elytra irregularly and closely punetate-striate. 
Length 13 line. 
Head very sparingly punctured, the labrum and mandibles black ; antenn two-thirds the length of the body, 
black, the lower four joints fulvous, the terminal five joints thickened; thorax transversely convex, twice 
as broad as long, the anterior portion deflexed, the anterior angles produced, the surface closely impressed 
with very evenly distributed, deep, elongate punctures; elytra convex, rather short, closely and compara- 
tively strongly punctate-striate, the shoulders prominent ; prosternum slightly narrowed at the middle. 
Hab. Mexico, Chilpancingo in Guerrero (H. H. Smith). 
A single specimen. A. puncticollis seems to possess the structural characters of 
Agbalus, although the tibie in the (apparently male) specimen obtained are unarmed; 
the crowded and elongate punctures of the thorax will help to distinguish the 
species.
