beyond the middle. Body beneath and legs pale testaceous ; 
thighs with a large dusky spot ; base and apex of tibise and tips 
of tarsi also dusky. 
Ega. The position of the lateral thoracic spines is almost the 
same as in Lophopceum bituherculatum ; the species would there- 
fore seem to belong to the last genus rather than to the present 
one ; but in the general shape of the body it agrees better with 
the species placed in the group Ozineus, the distance of the 
thoracic spines from the hind angles being probably due to the 
general elongation of the thorax and the rest of the body. 
2. Ozineus mysticus, n. sp. 
O. subelongatus, depressus, cinereo-fuscus, lineis angulatis canis 
ornatus : thoracis spinis lateralibus ab angulis posticis paulo di- 
stantibus : elytris postice modice atteiiuatis, apice peroblique 
sinuato-truncatis, angulis externis productis, carina centrobasali 
paulo elevata, elongata, pilis nigris cristata. Long. 3 lin. 
Head ashy brown; eyes distant above. Antennae greatly 
elongated and hair-like, rusty brown ; tips of joints (from the 
third) blackish. Thorax with the lateral spines placed at a short 
distance from the hind angles ; surface rusty brown, with several 
curved ashy lines. Elytra depressed, curvilinearly narrowed to 
the apex; sides with an obtuse carina; tips very obliquely 
sinuate-truncate, with the outer angles produced; the centro- 
basal ridge is elongated, very slightly raised, but fringed with 
black hairs ; the surface is moderately punctured in some parts, 
and is of an ashy-brown hue, with whitish ashy markings, which 
are in the form of lines near the base, but united in a very 
oblique angulated belt near the middle, two curved letters re- 
maining close to the suture near the apex. Body beneath and 
legs pallid ; thighs and tibise dusky near their apices.

3. Ozineus doctus, n. sp.

Head sooty black. Antennse the same, with the bases of the 
joints (from the third) pallid. Thorax with the lateral spines 
placed near the hind angles, sooty brown, with a few whitish 
specks. Elytra oblong, curvilinearly narrowed to the apex, 
which is very obliquely truncated, both angles pointed; sides 
with an obtuse lateral carina ; centro-basal ridges slightly raised, 
fringed with black hairs ; the surface thickly punctured nearly 
to the apex, sooty brown, with a number of ashy- white letter-
