334 MR. HENRY WALTER BATES ON PHASMIDA. 
Closely allied to Z. Praon and L. pseudoporus (Westw.), but differing greatly in the — 
shape and proportions of the terminal segments of the abdomen. A large number of © 
specimens arrived in the same collection from Ceylon, with a number of females of 
LL. cyllabacus (Westw.), unaccompanied by examples that could be taken without doubt « 
as the opposite sexes of the two species; so that it is possible, notwithstanding the total | 
want of resemblance in the armature of the legs, that L. flavicornis may be the male of M 
L. cyllabacus. 
The body is slender, cylindrical and shining; it is finely sculptured through. | 
out, however, with transverse striæ visible with a lens of small magnifying power; and - 
the thorax is sparingly granulated. The antennæ in all the examples before me (four) | 
have the apical halves of a pale yellow colour. The seventh segment of the abdomen is - 
very little shorter or broader than the sixth; the eighth is of nearly the same dimensions | 
as the seventh; the ninth or terminal segment is almost as long as the two preceding - 
taken together, and is narrowed behind, with the apex cleft to less than half the length | 
of the segment ; the two lobes formed by the fissure, however, are not straight, buf ` 
curved, forceps-like, and finely denticulated on their inner side. The legs are unarmed | 
and slender. v. 
Hab. Ceylon (Niefner). There are four examples, precisely agreeing, in Mr. Saunders’s collection. |

Allied to L. Stilpnus (Westw.) and L. nematodes (De Haan), with which species 1 
L. grallator agrees in the short, filiform antenne. Tt differs, however, from L. Stilpnus M 
in the unarmed condition of its legs, and from Z. nematodes in the oblong form of its 
head. 
The body and limbs are entirely smooth and unarmed. The antennæ are quite thread- 
shaped, or of equal and moderate thickness throughout. The seventh and eighth abdominal 
segments are a little wider than the rest of the abdomen, and are no longer, taken 
together, than the sixth. The terminal segment is much elongated and attenuated 
behind; it is cleft nearly to the base; the two lobes are quite straight, and have each à 
series of denticulations on their inner side; but their basal parts are deflexed, and meet 
on the underside, protecting the slender ànal styles, which are far from reaching the 
apex of the abdomen. The apical ventral segment is conically inflated. The legs 4 
very slender, and wholly unarmed. In the dead specimen they are of a yellow colout, 
with the knees and tips of the tibiæ black. The tarsi are greatly elongated and filiform.
