from the latter it is distinguished by its much larger size, 

 different shape and colour, etc. ; from the former by the 

 much less distances between the coxae. But, regarding the 

 granules as normally more or less obscured, then, as the 

 front coxae are not widely although very distinctly separated, 

 it would be associated with subglaber, cellaris, and spurcus, 

 from all of which it is readily distinguished by the abdomen. 

 In size and outlines it approaches piliventris, but that species 

 has the coxae more distant from each other, abdomen of male 

 less excavated and prothoracic granules smaller. 



At the base of the elytra on one specimen there are two 

 obscurely whitish spots of scales, so it is probable that on 

 well-preserved specimens the clothing would be variegated. 



Mandalotus bicarinatus, n. sp. 



(5 . Black ; antennae and tarsi more or less red, femora 

 and tibiae in parts obscurely diluted with red. Densely clothed 

 with muddy-grey scales, feebly variegated in places with 

 dingy- white. With rather short, semi-decumbent setae. 



Head wide, punctures normally concealed. Rostrum 

 short and stout ; scrobes extending backwards almost to eyos ■ 

 carina vaguely traceable through clothing. Antennae moder- 

 ately long; first joint of funicle stouter and slightly longer 

 than second. Prothorax moderately transverse, sides 

 strongly and evenly rounded ; with dense, round, flattened, 

 and normally partially-concealed granules. Elytra rather 

 short, at base as wide as widest part of prothorax, sides feebly 

 dilated to beyond the middle, and then coarctate to apex ; 

 with regular rows of rather large, but more or less concealed 

 punctures ; alternate interstices very feebly raised. M eta- 

 sternum flat across middle. Abdomen with basal segment 

 very feebly depressed in middle, a feebly-curved and shining 

 carina occupying one-third of its apex, a second but smaller 

 carina at apex of second segment. Legs rather short; front 

 coxae moderately separated. Length, 3-3i mm. 



9 • Differs in being wider, elytra subcordate, abdomen 

 without carinae, the basal segment gently convex, and the 

 legs and antennae somewhat shorter. 



Hab. — Tasmania: Hobart, under logs (A. M. Lea). 



In general appearance like very small specimens of 

 hlackburni, but abdomen with two carinae; the second one is 

 certainly less distinct than the first, but, as it is traceable on 

 the three males before me, I presume it is constant. In size, 

 and to a certain extent in appearance, it is fairly close to 

 bryophagus, but, apart from the carinae, it differs in having 

 the apex of the first abdominal segment incurved to the 

 middle, and the front coxae not touching.
