Sternacanthus piclicornis. 

 S. niger nitidus ; elytiis rubris, fasciis tribus nigris ornatis ; 

 antennis nigris, articulis 3-tiis, 4-tis, 5-tis flavis ; segmento 

 ultimo abdominis flavo. Para. 

 Closely resembles the Prionus undatus of Olivier, but is larger, 

 proportionably broader and more depressed, and has the lateral 

 abdominal segment of a dull yellow colour ; the bands on the 

 elytra are much narrower, and tlie black spot on the shoulder is 

 absent. I have only seen the specimen in my own collection, 

 which appears to be a female. 

 Length 1 1 lines. 



NoSERIUS. 



Head rather produced behind, but broad between the eyes ; 

 palpi equal, the maxillary thicker ; antennae moderate, the third 

 joint longest, the rest nearly equal ; thorax broader than long, 

 slightly depressed, tubercled laterally ; elytra long, rounded at 

 the apex ; legs moderate, slender ; thighs simple. 



Stromatium appears to be the nearest ally of this genus, from 

 which it differs in habit and the absence of the thoracic " plate." 



Noserius tibialh. (PI. XXIII. fig. 4.) 

 N. pallide-testaceus, pubescens ; antennis tibiisque piceis ; 



oculis apicibusque mandibularum nigris. Borneo. 

 Pale testaceous and delicately pubescent ; antennae, except the 

 first joint, blackish-brown; the eyes and tips of the mandibles 

 black; tibiae, the apices of the thighs and part of the first tarsal 

 joint pitchy black; prothorax with a minute tubercle at the sides; 

 elytra faintly striated ; scutellum minute. 

 Length 7 lines. 



Stromatium alienum. 



S. pallide-testaceum, pubescens ; prothorace mamillis duabus 

 posticis ; elytris parallelis tricostatis, punctis elevalis sparsis 

 aspersis. Espiritu Santo (Brasili;i). 



Pale testaceous, finely pubescent ; prothorax at each posterior 

 angle with a round mamillated protuberance ; elytra with three or 

 four rows of elevated points and three ribs, the inner or sutural 

 one being very short and almost obsolete, the two others gradually 

 increasing in length and distinctness, while at the apex there 

 appears another, formed, however, by the deflection of the 

 elytron. 



Length 6 lines.
