being sinuated. The anal styles are small, and wholly concealed under the apical seg. M 
ments. The apical ventral segments are elongated, and only moderately convex beneath, « 
the tip reaching to the base of the terminal dorsal segment. The legs are all greatly ; 
elongated and simple, the intermediate pair being very little shorter than the front and — 
hind pair. The basal joint of the tarsi is excessively elongated, being about double the « 
length of the remaining joints taken together. 
Hab. One example, from Brazil. 
BACTERIA SAKAI, n.sp. B. cylindrica, fusco-grisea, capite pedibusque inermibus, cor- 
pore albo minute granulato, thoracis lateribus sparse denticulatis, mesonoto spinis -

EO y métath. 1" 1^ ;:abdom. 3:62 (PL XLIV. f. 1) 
Head oval, scarcely convex, unarmed; mesonotum furnished with short scattered 
spines, a few of those on the middle portion being larger than the rest and stouter, but 
sharply pointed ; mesonotum unarmed above, having only a few short denticulations on 
the sides. Abdomen cylindrical to the apex, the fourth dorsal segment having in the 
middle of its apical margin a small tubercle; the apical segment is rather longer than. | 
the preceding, and is sinuated on its front margin, with the lateral angles very obtuse. - 
Anal styles inconspicuous. Sixth ventral segment narrowed and bifid at the tip. Va- - 
ginal opereulum surpassing (by a length of about two lines) the tip of the abdomen, | 
scarcely convex, obtuse at its apex; sides of the penultimate ventral segment visible, the M 
hind angles being greatly elongated and deflexed. Legs moderately stout, basal joint of | 
the tarsi scarcely longer than the three following united, compressed and erested. The 
whole body is covered with very small whitish granulations, most conspicuous on the 
underside of the thorax ; its colour is dingy-greenish or brownish-grey. 
Hab. Two examples, taken at Ega, Upper Amazons. The male of this species would be closely allied to . 
B. muricata (Burm.). I have given to the insect the name which it bears amongst the Indians | 
namely Sakai, a twig or stem.

This species resembles much Z. Wallacei (Acanthoderus id., Westw.), diffe 
in the presence of two spines on the head, and in the short and horizontal form
