This is probably the most remarkable genus of the Hispidae, wholly 

 distinct in habit from any other known species, although most nearly 

 related to Eurispa. The prolongation of the head behind the eyes, 

 the size and figure of the anterior femora, the two formidable teeth 

 on the protibia) (as is also the case in some Cephalodontae), and trigo- 

 nate outline of the elytra terminating in two thick spines, combine to 

 produce a form that, taken in conjunction with the congeners of its 

 own family, renders it one of the most striking of the Australian 

 Coleoptera. The parts of the mouth can only be described as they 

 are seen in situ, and these are the more difficult to distinguish as 

 they are placed in a deep cavity formed by the mandibles in front, 

 and by the jugular plate, bent down at a right angle, behind ; it may 

 be also noticed that the angle itself is bordered by an elevated, narrow 

 ridge. I am indebted to Mr. Baly, who is so well known for his 

 Monograph of this family and for his knowledge of the Phytophagous 

 groups in general, for his assistance in this examination; he is satisfied 

 of the existence of a small square mentum which is attached to the 

 anterior edge of the reflected portion of the jugular plate, and that 

 the last two joints of the maxillary palpi are together of a globose 

 form, and those of the labial oblong-ovate. 



Aproida Bahji. (PI. II. fig. 8.) 



A. flavescens, vitta fusco-purpurea ab oculis ad apicem elytrorum ornata ; 

 antennis fusco-purpureis, articulis duobus ultimis albis. 



JIab. Queensland. 



Fulvous, on the elytra inclining to lemon-yellow, a dark-pui*ple line 

 extending from the eye to the apex of the latter ; head coarsely punc- 

 tured, elongate behind, the front vertical, with a tubercle before each 

 eye, bearing the antennae ; eyes ovate, prominent ; antenna) about half 

 the length of the body, dark chestnut-brown, the last two joints pale 

 straw-yellow, the basal joint short, incrassate, the second about the 

 same length as the first, the remainder longer, cylindrical, the last 

 terminated by a small hooked appendage ; prothorax quadrilateral,
