tubercle at the anterior angles. In the absence of long 

 series, it can only be said that there are no present 

 reasons for doubting the substantial identity of all these 

 forms ; the differences in the shape of the prothorax 

 appear to be sexual, the trapezoidal shape existing in the 

 female, although the New Guinea example, apparently a 

 male, as its front is impressed, offers some difficulty 

 towards the acceptance of this supposition. 



Phloeosinus cribratus, sp. n. 



Fem. (?) Oblongo-obovata, picea, antennis pedibusque ruf escen- 

 tibus ; prothorace semielliptico, subglabro, subnitido, fortiter 

 punctato, linea media subelevata Itevi ; elytris crenato-striatis, 

 interstitiis transverse rugosis, in declivitate, 2° , i^exceptis, seriato- 

 tuberculatis et brevissime setosis. Long. 2 mm. 



Female. (?). Oblong-obovate. Head pitchy-black, the front 

 shining, rather strongly but not rugosely punctured, above convex, 

 with a median tubercle, impressed below and smoother, scantily 

 and shortly hairy, the mouth with a very short yellowish fringe ; 

 eyes bipartite, the emargination just reaching the posterior border 

 of the eye ; antenna yellow-testaceous, normal, the club finely 

 and closely pubescent. Prothorax as long as broad, narrowed from 

 the base, the sides and apex rounded in a conjoint ellipse, the basal 

 border bisinuate, forming an obtuse angle in the middle ; surface 

 reddish piceous, shining, subglabrous, strongly but not rugosely 

 punctate, the median line smooth, subelevated. Elytra a httle 

 wider than the prothorax, and three-fourths longer, their basal 

 margins oblique, narrowly elevated and crenate, the sides sinuate 

 and subampliated behind, the apex broadly rounded ; surface 

 piceous, reddish posteriorly, crenate-striate, the striae deep but not 

 wide, siibequal throughout, interstices subconvex, more strongly on 

 the declivity, closely and transversely rugulose, with very short uni- 

 seriate squamiform bristles (probably from base to apex in fresh 

 examples), and behmd the middle with small uniseriate tubercles, 

 absent towards the apex of the 2nd and 4th interstices, the bristles 

 irregularly biseriate on the apex of the other interstices. Under- 

 side and legs rufescent ; 3rd tarsal joint simple. 



Hah. Sumatra, from tobacco (Grouvelle). 



The neai^est ally of this species appears to be P. detersus, 

 Chap., from Ceylon, which is very much larger, with 

 the prothorax more finely and remotely punctate, the
