Genera and Species of Coleoptera. 55 
Aprorpa [ Hispidee ]. 
Caput pone oculos subelongatum ; fronte brevi, verticali; clypeo bilobato, 
labrum occultante. Oculi ovati. Palpi macillares articulis ultimis duobus 
globosis. Palpi labiales articulis ultimis oblongo-ovatis. Mentwm qua- 
dratum. Antenne filiformes, super tuberculis inter oculos inserte, arti- 
culis duobus basalibus brevibus, primo incrassato, czeteris brevioribus, 
ultimo paullo longiore apice appendiculato. Prothorax quadrilateralis, 
postice latior. /ytra deplanata, subtrigona, thorace latiora, apice cau- 
data. Pedes breves; femoribus anticis incrassatis, dentatis ; cibiis ejusdem 
curvatis, introrsum bispinosis. Corpus subplanatum. 
This is probably the most remarkable genus of the Hispidee, wholly 
distinct in habit from any other known species, although most nearly 
related to Hurispa. The prolongation of the head behind the eyes, 
the size and figure of the anterior femora, the two formidable teeth 
on the protibie (as is also the case in some Cephalodontz), 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 im 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 Balyi. (Pl. II. fig. 8.) 
A, flavescens, vitta fusco-purpurea ab oculis ad apicem elytrorum ornata ; 
antennis fusco-purpureis, articulis duobus ultimis albis. 
Tab. Queensland. 
Fulvous, on the elytra inclining to lemon-yellow, a dark-purple 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 antenn ; eyes ovate, prominent ; antenne 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,
