notum, veins distinct. Wing-lobes rudimentary, concealed by 
the elytra. Hind femora with six pairs of small spines. Hind 
tibize with four to six external and six to eight internal spines, 
all black at the apex. Femora near apex, and all the tibie and 
tarsi, hirsute, like Z. tigrinus (omitted to state in monograph). 
Ovipositor very slender and long, nearly straight, acute, apex 
black.

The two specimens obtained differ principally from #. tigrinus 
(independently of color and size) in the black, toothed apex of 
the mandibles, almost concolorous pronotum, much longer elytra, 
different arrangement and size of spines, and the more slender 
ovipositor; from Z. atrofrons and EL. fumatus in much larger 
size, pale head, and number, &c., of spines. 
The ova were extracted from both the specimens, and proved 
to be nearly mature, in the one more so than in the other. One 
yielded 47, the other 24, a small proportion were only about 
half-grown. The mature ones were brown, elongate elliptical, 
5-5-5 mm. in length, somewhat thicker on one end than the 
other, each terminating with a circular, smooth, shining, darker 
lid, the intermediate portion being ornamented with crowded 
microscopical papilla, arranged in regular diagonals. The small, 
immature (or male ?) ova are almost cylindrical.

Two specimens were secured, viz., a nearly mature male 
nymph (the first example of this sex for the genus) and a female 
larva. As the species was originally established from a singie 
female, these not only confirm its validity, but the former supple- 
ments the generic description, hence a full description becomes 
necessary. 
Male (nymph) similar to female, but considerably smaller. 
Abdominal segments 8 and 9 almost concolorous ; hindmargin 
of the latter straight, angles lobe-like produced. Supra-anal 
lamina transverse, divided by four furrows into five unequal 
parts, the central sulcus produced posteriorly as a dilated rotund- 
ate lobe, and longer than the basal part. Cerci very short, apex 
blackish. Subgenital lamina small, subquadrangular, rather 
longer than wide, simple. Styles minute.
