9 . Differs in having the prothorax smaller, elytra 

 larger and wider, mesosternum simjole, abdomen flat at base, 

 and legs shorter. 



Hal).— New Sonth Wales: Blue Mountains (E. W. Fer- 

 guson). 



Readily distinguished from all other species of the genus 

 (many of which it strongly resembles) by the intercoxal pro- 

 cess of mesosternum of male, this being produced and notched 

 at apex, instead of laminated as in A of my table, or conical 

 a,s in AA. 



Mandalotus mesosternalis, n. sp. 

 d . Black ; antennae dull-red, scape darker, tarsi red- 

 •dish-castaneous. Densely clothed with stout muddy or sooty- 

 brown scales, more or less variegated with paler scales. With 

 stout slightly-curved setae, similar in colour to the scales 

 amongst which they are placed. 



Itosfruni with a narrow carina, visible throughout. Scape 

 moderately short and stout. Froth or ax truncate in front, 

 rounded at base and sides ; with numerous strong, transverse, 

 or oblique carinse, interrupted in middle, and quite distinct 

 before abrasion. Eh/tra conjointly arcuate at base ; with a 

 moderately strong subhumeral tubercle ; disc even ; with 

 rows of large, normally almost concealed punctures ; alter- 

 nate interstices slightly raised. Under surface with dense 

 punctures and sparse minute granules, both normally con- 

 cealed. Mesosternum with a strong, conical, intercoxal pro- 

 cess. Basal segment of abdomen somewhat depressed in 

 middle. Front coxee lightly but distinctly separated; four 

 hind tibice strongly notched near apex. Length, 3^-5 mm. 



9 . Differs in having the elytra larger and wider, meso- 

 sternum simple, basal segment of abdomen convex in middle, 

 and legs shorter, with thinner femora and simple tibiae. 



Hah. — New South Wales: National Park (H. J. Car- 

 ter), Sydney (E. W. Ferguson). 



In my table would be placed in A A, from all of which 

 it is distinguished by the much longer mesosternal process (in 

 length this is about equal to each of the front coxEe), and 

 by transverse carinae replacing the usual prothoracic granules. 



One specimen has all the legs obscurely diluted with red. 

 The paler scales appear to be variable ; on one female they 

 form very feeble stripes on the prothorax, clothe each 

 shoulder, form a small spot on the third interstice at base, 

 and a fairly distinct curved fascia at summit of posterior 

 declivity. On another female they clothe the sides almost 

 regularly from apex of prothorax to apex of elytra ; on this 

 specimen also most of the elytral scales are brownish. On 

 .a male the only scales that are variegated are some on the
