accompanied by an obsolete longiturlinal (lci>ression ; sciitelliiiii fulvous, its apex 

 broadlv rounded; el3'tra widened at the middle, closely and finely Init distinctly 

 pnnctured, the apex with a short transverse fulvous band, legs robust, fulvous 

 as well as the abdomeji, breast nearly black ; the last abdominal segment of tlie 

 imde with a very short incision at each side, the median lobe much broader 

 than long. 



Hah. Andai (New (iuinea). A single specimen. 



Easily distinguished by the colour of the antennae, their length and the 

 fulvous apex of the elytra, from any of its congeners. 



Ochralea imitaus sp. nov. 



Fulvous, the antennae, the breast, and the tibiae and tarsi black, the head and 

 thorax rufous, the latter rugosely punctured, elytra very closely punctured, pale 

 fulvous, naiTowly margined with black. 



Length 2i to 3 lines. 



Elongate, convex, the head nearly impunetate, the frontal elevations narrowly 

 transverse, eves large, antennae slender, black (the basal joints sometimes fulvous), 

 second and third joints short, nearly equal, fourth and following joints very elongate; 

 thorax twice as liroad as long, the anterior margin straight, the posterior one and 

 the .sides slightly rounded, the disc with an obsolete transverse depression at the 

 sides, rugosely punctured, the anterior half rufous, the basal portion jjaler ; scutellum 

 black ; elytra convex, slightly widened posteriorly, very closely and strongly punc- 

 tured, all the margins narrowly black. 



Hah. Perak. 



0. imitans closely resembles (). marginata .Tac, but differs in its smaller size, 

 the black antennae, tibiae and tarsi, and the closely rugose thorax. 



Candezea bimaculata .lac. 



r?. Head with two conical tuliercles on the vertex, antennae, with tlie third joint 

 but slightly longer than the second, elytral costae absent. 



Var. The elytral basal band entire, without enclosing a fulvous spot, or trifurcate. 



Hah. Humboldt Bay and Andai (Xew (iuinea). 



The type of this species, deserilied liy me in the Genoa Annals of 1886, from 

 female specimens, is very different from the other six obtained by Mr. Doherty, on 

 account of the tuberculate vertex of the head, which is quite an exceptional striicture 

 amongst the numerous (ialerucidae. In regard to colour the present si>ecies seems 

 also suliject to great variation ; in some specimens the basal black band of the elytra 

 is divided into three short stripes, while in others it is entire. Typical si)ecimens 

 with a fulvous spot placed witliin tlie elytral Viand were not obtained; in some the 

 four posterior femora are only black at the base, and the abdomen is also spotted 

 more or less at the middle with the same colour. T have, however, not much doubt 

 that all are varieties of my species, as structural differences seem not to lie present ; 

 thefeviales have the elytra costate as in tlie type, while in the vudes they are nearly 

 smooth. In one or two instances the elytral band only occupies the basal margin, 

 as in Monolepfa basimarginata Boisd. ; but in that species the elytra are finely and 

 closely (lunctured, of a very pale testaceous, and the general size of the insect is 

 smaller and less robust.
