from those of H. purpureo-micans: in H. terebrans they are formed as above described ; 
in H. purpureo-micans as in all the allied species examined, ¢. g. the sheath simple and 
pointed at the apex. In many of the male examples of H. terebrans before me the 
inner bilobed sheath (enclosing the simple central tube) is extruded and plainly visible. 
The dissection of a good many species of Tenebrionide has not yet revealed to me any 
structure of the male organs similar to what is to be found in H. terebrans; in the cedeagus 
of Pedinus I have found a long and stout spine-like process on each side of, but not 
attached to, the inner tube, the latter being enclosed in a sheath of the ordinary simple 
character. In Z. terebrans there appear to be two horny sheaths *, the outer one short and 
capable of expansion when the long bilobed inner one is extruded; I can find nothing 
analogous to this in the other species of the genus dissected, all appear to have the 
outer sheath simple at the apex (and apparently not capable of expansion) and without 
trace of an inner one. Dissection of other allied forms may probably reveal a similar 
structure. We thus have two apparently very closely allied species furnished with very 
dissimilar male sexual organs. 
In this species the elytra constantly exhibit traces of the metallic stripes, which are 
not entirely obliterated in any of the examples before me. We figure a male example 
from the Volcan de Chiriqui; also the male (fig. 26 a) and female (fig. 26 6) secondary 
sexual organs.

Generally distributed in our country. The long series of examples connect the 
numerous varieties of this insect. The elytra in some examples have one dorsal 
brownish stripe, in others two black stripes; rarely the elytra are entirely testaceous. 
The variety with one stripe (sometimes obsolete) often has the disc of the thorax more 
or less marked with black anteriorly: this form I have only seen from Cordova, where 
also the two-striped variety is found. 
Examples from Guatemala southwards have smoother elytra, and the punctures not 
sO closely placed. Jalapa specimens are comparatively narrow and have the rows of 
punctures on the elytra deeply impressed. H. boucardi, like the other species of the’
