many of the smaller Dynastides. The pygidium, although 

 itself glabrous, is fringed with long hairs, these being much 

 more conspicuous on the propygidium than is usual in the 

 genus. On the male the rami of the club are about once and 

 one-half the length of those of the female. 



Haplonycha dilatata, n. sp. 



Piceous-brown (almost black) ; prothorax and scutellum 

 of a dingy-red, antennae paler. Sterna and legs with rather 

 dense, whitish hairs, lateral gutters of pronotum with a few 

 long hairs ; elytra with membranous fringe very short ; 

 pygidium very sparsely clothed. 



Head with dense punctures of moderate size ; clypeus not 

 specially convex at middle of base, front face of clypeus with 

 rather dense punctures, but the setiferous ones across middle 

 confined to a single row. Antennae with third and fourth 

 joints rather short and subequal, seventh-ninth forming a 

 club. Maxillary palpi with apical and antepenultimate joints 

 rather long and equal, and distinctly longer than the 

 penultimate. Prothorax not thrice as wide as long, sides 

 strongly rounded, front angles produced and acute, hind ones 

 rounded off ; punctures numerous and rather small. Elytra 

 rather strongly dilated to beyond the middle; geminate- 

 striae distinct, the space between each pair rather narrow, 

 convex, and impunctate, but with numerous punctures 

 between pair and pair; suture unarmed. Pygidium with 

 small, crowded punctures almost throughout; with a distinct 

 elongate tubercle (or subcarinate swelling) in middle. Basal 

 joint of hind tarsi distinctly shorter than second. Length, 

 11-12J mm.

In Blackburn's table of Group 6, would be associated 

 with jjectoralis and pygmaea,^ and its elytral punctures 

 are intermediate in character between those of the two species 

 named, but in general appearance it is not very close to them; 

 it is smaller than pygmaea, the elytra more dilated posteriorly 

 and the pygidium very different. Four other specimens from 

 Cairns appear to belong to this species, but differ in being 

 entirely pale-castaneous, the antennal rami shorter, the elytra 

 even more dilated posteriorly, and the tubercular swelling of 

 the pygidium less evident, they are probably females, and the 

 others are probably males.
