1 . Ozineus elongatus, n. sp. 



O. angustatus, elongatus, postice parum attenuatus, carneo-cinereus, 

 ferrugineo-fusco maoulatus : thoracis spinis lateralibus pone me- 

 dium positis. Long. 3^ lin. 



Head dusky : eyes large, nearly touching above ; labrum yel- 

 low. Antennse much elongated, capilliform, rusty brown, base 

 of joints pallid. Thorax rather elongated, the lateral spines 

 placed behind the middle, but leaving a considerable space be- 

 tween them and the hind angles ; surface punctured, pinkish 

 ashy, with dark-brown spots. Elytra narrow and elongate, 

 tapering posteriorly to the apex, which is briefly truncate, the 

 angles not produced; sides and disk without raised lines, the 

 centro-basal ridges rising in the form of small tubercles crested 

 with hairs ; the surface (except the apical part) is punctured, 

 and is of a pinkish-ashy hue, with numerous darker-coloured 

 spots, some of which are collected into a transverse belt a little 

 beyond the middle. Body beneath and legs pale testaceous ; 

 thighs with a large dusky spot; base and apex of tibiae 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 postieis paulo di- 

 stantibus : elytris postice modice attenuatis, apice peroblique 

 sinuato-truncatis, angulis externis productis, carina centrobasali 

 paulo elevata, elongata, pilis nigris cristata. Long. 3 lin. 



Head ashy brown; eyes distant above. Antennse 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-
