MR. J. S. BALT ON SOME GENERA 
fails in the present group for the following reason. In many 
species of Monolepta (including the typical one) the elytral 
epipleura gradually narrows towards the apex and extends back- 
wards for nearly the whole length of the outer margin of the 
elytron ; in others, the epipleura apparently ends at or about the 
middle of the margin ; on examination, however, it will be seen 
that it does not terminate at that point, but although much 
narrowed extends to a greater or less extent along the hinder 
margin. The point at which the contraction takes place also 
varies greatly, so that I have thought it well to place all the 
species here described in Monolepta. 
1. Monolepta h^emorrhoidalis, Fabr. Syst. El. i. p. 490; Oliv. 
Ent. vi. p. 629, t. 3. fig. 33. — Auguste ovata, postice paullo 
ampliata, convexa, flava aut rufo-flava, nitida, antennarum articulis 
intermediis et apicalibus nigris aut nigro-piceis ; thorace quam longo 
distincte latiore, eonvexo, laevi ; elytris convexis, nigris, apice plus 
minusve sanguineis. Long. 2|-3 lin. 
Mas. Elytro utroque ante medium fovea magna subrotundata, margine 
incrassata munito. 
Hab. Australia ; New Guinea, Mysol, Sulu Islands. 
Antennae filiform, the third joint about one half longer than 
the second ; the three lower joints flavous, the eighth, ninth, and 
tenth, together with the basal portion of the eleventh, flavous ; the 
upper portion of this last, together with the fourth to the seventh, 
black, or nigro-piceous. Thorax about one fourth broader than 
long ; sides rounded, nearly straight and slightly diverging be- 
hind the middle, anterior angle armed with an obtuse tubercle ; 
disk convex, smooth. Elytra oval, convex, slightly excavated 
below the basilar space in the $ , minutely punctured ; black, 
the apical portion to a greater or less extent bright sanguineous ; 
each elytron in the J 1 is impressed with a large rotunda-te-ovate 
fovea placed on the anterior disk about halfway between the outer 
margin and the suture, and extending downwards to a little below 
the median line. Elytral epipleurae extending below the middle. 
Anterior acetabula closed. 
I possess two specimens of this species (both males) from 
Australia, the original locality given by Eabricius and Olivier, 
one, if not both, having formed part of the collection made during 
the voyage ol the ‘ Coquille.’ In these specimens the sanguiueous 
coloration of the elytra is confined to the extreme apex, but in 
those from the Malay Archipelago, collected by Mr. Wallace,
