The anterior tibi® are flattened at the apex and produced into an acute angle on the outer margin^ the
inner angle being destitute of a spur. The four hind tibi® are furnished with a short spur at the inner apex.
The lower parts of the mouth seem to approach nearest to those of Tcleas, as figured by Curtis.

Closely allied to II. Gray'u (Westw. Mon. Phasm. pi. XXX. fig. 3), but much larger, though with the
spines much smaller; the tegmina and wings extend to the extremity of the second dorsal segment of the
abdomen. The two anterior discoidal spines of the prothoras are smaller than the four posterior ones forming
the posterior row, which are much more numerous and still smaller in II. Grayii. The mesothorax has the
square central dorsal part armed with three marginal spines on each side, three pairs of distant spines on its
disc, and only two approximatory spines in the place of the posterior coronet of spines in S. Grayii-, the tegmina
are comparatively larger, and extend to the extremity of the second abdominal segment.
The sides of the body and the femora are much less strongly spined than in H. Grayii, but the tibial spines
are very robust.
The exposed portion of tbe dorsal piece of the ovipositor (fig. \ a , g ) is elongate-lanceolate, narrow, gradually
pointed to the tip, where it is slightly furcate, and is half as long again as the terminal dorsal segment (*).
Fig. 1 a represents the four terminal segments of the body of the female lying on its back, with the parts of
the oidpositor raised and separated, and fig. I h the ventral surface of the ovipositor, the lettering of the different
parts being' the same in both figures ; the * representing the ninth or terminal segment of the abdomen.
a represents the large boat-shaped piece arising at the base of the seventh segment, and shutting in the
other parts when at rest; i, a pair of curved horny blades, each arising from a broad basal piece, c; cl, two
shorter horny bifid plates, which unite with I to form a concave bed for the reception of the larger eggs; e, the
under lining of the basal part of the last segment; J\ a pair of straight horny conical appendages, at the base
of each of which is seen a minute conical style; g, the under side of the upper portion of the sheath of the
ovipositor, and t the entrance of the anus.
I had named the specimen of this species, figured in plate XXXI I , in memory of the late Rev. F. W. Hope,
the munificent founder of the Chair of Zoology in the University of Oxford, to whom these curious insects were
especial objects of interest, haying never seen the original type of K. dilaiata, the Hopeian specimen being in
spirits and discoloured. The Saundersian Collection, however, now added to tbe Hopeian Museum by the
liberality of Mrs. Hope, contains a dried s])ecimen, and has enabled me to identify the species.
