OTTEISSA. 
Caput elongatum, antice productum, collo distincto. Oculi subangusti, 
leviter emarginati. Palpi cylindrici, obtusi. Antenne graciles, corpore 
breviores, scapo modice elongato, articulis tertio ad sextum equalibus, 
ceeteris gradatim decrescentibus. Prothorax antice constrictus, lateraliter 
inermis, disco utroque nodosus. Elytra oblonga, apice integra. Pedes 
modice elongati. Mesosternum declivum. 
Most of the characters of this genus are also those of Vowotus ; but 
it differs essentially in the antenne, the fourth joint being of the 
normal length, the unarmed prothorax, and the sloping mesoster- 
num. ‘This is the only one of the Lepturine that I have seen from 
South Africa, although M. Thomson has two genera from the Cape, 
both of which are unknown to me: one of these, from the description, 
(Pachyticon) would seem to be an aberrant form, as its antenne are 
three times as long as the body. In the other (Aristogitus) the males 
have elongated antenne, with flattened and dilated joints ; the female 
resembles Rhagium. 
Otteissa sericea. 
O. pube sericea murina tecta; corpore infra et femoribus basi rufescenti- 
bus; abdomine nigro. 
Hab. Natal. 
Head, prothorax, and elytra covered with a short silky pubescence of 
a pale greyish-smoky or mouse colour, without any evident punctu- 
ation; node on the prothorax on each side rather large, and having a 
transverse impression in front; pectus and femora at the base reddish 
testaceous; abdomen black or very dark brown, with a thin greyish 
pile; legs dark brown, antennee paler. Length 6 lines. 
Phyllocnema mirifica, (Pl. XIII. fig. 4.) 
P. cyaneus; elytris chalybeatis; antennis pedibusque, tibiis posticis ex- 
ceptis, luteis. 
Hab, Nata. 
Head and prothorax deep indigo-blue, both very closely and coarsely 
punctured, each puncture at the base azure blue; scutellum and elytra 
dark chalybeate blue, the latter finely and closely punctured with a 
slightly raised line on each; antennz, lip, mandibles, and legs luteous 
yellow, except the dilated portion of the posterior tibiee, which is of a 
rich dark blue; body beneath black. Length 7 lines. 
In this remarkable species the posterior femora and their tibie, 
taken together, are about thrice the length of the elytra, and the
