350 MR. HENRY WALTER BATES ON PHASMIDÆ. 
three penultimate segments elevated in the middle. The three basal joints of the poste. 
rior tarsi are produced at their apex (on one side) into a lobe. 
Hab. Santarem, on the Amazons. Taken by myself. 
The following is an extract from my notebook referring to this insect :—“ The com. - 
monest species in these woods, and, I think, generally distributed. It moves-slowly over 
the branches and leaves of low trees, and flies readily, but heavily, when disturbed. | 
When seized with the hand, a dark liquor oozes from the mouth and other parts of the 
body, emitting a most peculiar and disagreeable odour. ‚In copulation the male mounts 
on the back of the female, his head reaching only as far as the elytra of his partner, and 
grasps her body strongly with his anterior legs, the flexible apex of the abdomen being 
curled round to the genital organs of the female underneath the tip of her abdomen." 
Hab. There is a male specimen also in Mr. Saunders’s Collection, labelled as from Peru. 
PHASMA QUADRATUM. Mas. Cylindricum, tenue, viride, olivaceo-fusco variegatum ; capite 
subquadrato, supra plano, ocellis patentibus; tegminibus oblongo-quadratis, apice 
recte subtruncatis, carina ante medium in spinam validam acutam exeunte ; alarum 
area costali olivaceo-viridi plagiata, membrana pallide fusca diaphana; abdomine - 
elongato ; stylis analibus brevibus, eylindrieis ; segmento ventrali 8vo profunde emar- | 
ginato; pedibus brevibus.—Long. corp. 1” 10"; anten. 1” 10’; mesothor. 2"; 
abdom. 11""--3"—1" 2”; tegmin. 3”; ale 1”. 
Allied to Phasma maculatum (Gray and Westw.), but distinguished by the elongate, 
oblong, and obtusely but straightly truneated tegmina. The raised part of the carina, 
im consequence of the prolongation of the apical part of the tegmina, is much nearer the | 
i base than the apex, and is, moreover, surmounted by a rather long and sharp spine, | 
inclined towards the apex of the tegmen. The colour of the tegmina, like that of the 
body, antenne, legs, and costal area of the wings, is obscure-olivaceous, relieved by 
indistinct marks of a clearer green. The membrane of the wings is light brown, without 
trace of deeper shade towards the margins. The legs are extremely short (as in many 
allied species of Phasma, especially from the same country), the hind legs, when | 
extended, being much shorter than the abdomen (103 lines). 
Hab. Forests of the Tapajos, near Santarem. One example (2).
