forms in the rugose posterior lobe of the pronotum. The male has the two spines at 
the apex of the terminal genital segment moderately long, divergent, upwardly curved, 
and very widely separated, the apical margin of the segment being broadly truncate 
between them. The Signoret specimen is figured.

Apparently a common insect in Chiriqui, whence we have obtained a large number 
of specimens, chiefly from the savanas of the “tierra caliente.” It is a rather small, 
robust species, with stout, closely setose legs, and the intermediate and hind femora 
considerably swollen before the apex. The colour is very variable: the pronotum and 
corium (except at the tip), and the anterior legs in part, are flavo-testaceous in light- 
coloured specimens, the darkest individuals being almost entirely black. A. emargi- 
natus differs from all the other Central-American forms in the laterally emarginate base 
of the pronotum, as well as in the very peculiar armature of the terminal genital 
segment in the male. In this sex the apex of the terminal segment is somewhat 
broadly produced in the centre and armed with two very long, upwardly curved, slightly 
divergent spines; the claspers are very long and sinuous, angularly dilated and closely 
ciliate on the inner side about the middle, and strongly curved beyond, the apical 
portion bearing a few very long sete on the outer edge; at the base of these claspers 
on the inner side a second short curved pair is visible.

Sent to us from Western Mexico only. ‘These specimens are extremely like some 
of the varieties of A. pictipes, and they are only separable therefrom by the very 
different form of the external genital armature of the males. They have the venter 
entirely black, or, rarely, with traces of transverse dirty yellowish lines at the sides; 
the connexivum in some of them is entirely black, or has the outer margin very 
narrowly pale; the pronotum rufous, with two broad transverse black fascia, which are
