fails in the present group for the following reason. In many 

 species of Monolepta (including the typical one) the eljtral 

 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^morrhoidalis, Fahr. Syst. El. i. p. 490; Oliv. 

 Ent. vi. p. 629, t. 3. fig. 3'3. — Anguste ovata, postice paullo 

 ampliata, convexa, flava aut rufo-flava, nitida, antennarum articulis 

 intermediis et apicalibus nigris aut nigro-piceis ; thorace quara longo 

 distincte latiore, convexo, laevi ; elytris convexis, nigris, apice plus 

 minusve sanguineis. Long. 2|-3 hn. 



Mas. Elytro utroque ante medium fovea magna subrotundata, margine 

 inerassata munito. 



Sah. 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 2 , minutely punctured ; black, 

 the apical portion to a greater or less extent briglit sanguineous ; 

 each elytron in the J is impressed with a large rotundate-ovate 

 fovea placed on the anterior disk about halfway between the ouler 

 margin and tbe suture, and extending downwards to a little below 

 the median line. Elytral epipleurse extending below the middle. 

 Anterior acetabula closed. 



I possess two specimens of this sj^ecies (both males) from 

 Australia, the original locality given by Fabricius and Olivier, 

 one, if not both, having formed part of the collection made during 

 the voyage ol the ' Coquille.' In these specimens the sanguineous 

 coloration of the elytra is confined to the extreme apex, but in 

 those from the Malay Archipelago, collected by Mr. Wallace,
