are often sharply denned, but are mostly rugose, some of them 

 are so shallow as to be scarcely traceable, especially about 

 the tips. The antennae are not subpectinate, so regarding 

 the species as belonging to GG of my table it would be asso- 

 ciated with 0. atricapillis, from which it differs in most 

 details of shape; if it were referred to Helcogaster, it would 

 be associated with H. punctipennis, with which it has also 

 few details in common. 



Neocarphurus costipennis, n. sp. 



9- Black; antennae, except some of the apical joints, 

 and extreme base of prothorax flavous. A few. dark hairs 

 scattered about. 



Head opaque and with rather dense punctures, a shallow 

 depression each side in front, and a shallow median line. 

 Antennae .moderately long, none of the joints transverse. 

 Prothorax slightly longer than greatest width, which is at 

 apex, sides rounded and strongly narrowed to near base, and 

 then almost parallel to base, which is feebly bilobed, a deep, 

 transverse, open depression near base. Elytra almost twice 

 the length of prothorax, and twice as wide as its base, opaque 

 and shagreened except about base, a fine costa extending 

 obliquely inwards from each shoulder. Length, 2"5-2'75 mm. 



Rab. — Northern Queensland (Blackburn's collection), 

 Cairns (Dr. E. W. Ferguson). Type, I. 10948. 



The opacity of the elytra appears to be due principally 

 to very minute pubescence, but the species may be readily 

 known from N . pilosipetiTiis, N. angustibasis, and all others 

 of the genus, by the costa running inwards from each shoulder 

 for about one-third the length of the elytron. On the type 

 the three apical joints of the antennae, and the upper-surface 

 of the first, are infuscated ; on a second specimen only the 

 two apical joints are infuscated. 



Neocarphurus semiflavus, n. sp. 



Flavous ; metasternum and abdomen black ; apical three- 

 fifths of elytra, parts of hind legs, of middle and of front 

 tibiae and tarsi, and two apical joints of antennae, more or 

 less deeply infuscated. With a few straggling hairs. 



Head with a wide depression between eyes, and a large, 

 obtuse, inter-antennary tubercle. Antennae moderatelv long, 

 second to sixth joints transverse, eleventh longer than tenth. 

 Prothorax longer than wide, sides rounded and strongly nar- 

 rowed to near base, and then subparallel to base, which is 

 feebly bilobed and about half the width of apex. Elytra 

 about once and one-half the length of prothorax, and much
