9 • Differs in being more robust, abdomen more convex., 

 and without a semicircular glabrous space, and the tibiae less 

 curved. 



Hab. — Queensland : Mount Tambourine, in rotting leaves 

 (A. M. Lea). Type, I. 2716. 



In general appearance strikingly like latens, and 

 obtained from the same lot of rotting leaves. I had, in fact, 

 the two species mounted together, but in floating them off and 

 examining the abdomen the males were seen to belong to two 

 different sections of the genus. The present species has no 

 tubercles on the basal segment of abdomen, but has an 

 abruptly terminated semicircular shining space, not encroach- 

 ing on the second segment (as in ventrcdis) nor terminated by 

 a carina, as in so many species of the genus, but bent down 

 at the tip; it is, in fact, much as in jmnctiventris, which, 

 however, differs in many other features. Before abrasion 

 the prothoracic granules are so indistinct that it is difficult 

 to see how they are disposed, but on abrasion they are seen 

 to be large and in the form of short transverse or oblique 

 ridges. Consequently in the present table the species should 

 be placed with arcuatus. But as the transverse arrangement 

 is less conspicuous than in other species and is not at all 

 traceable before abrasion, I originally placed it in the table 

 immediately after avenaceus ; from all the species following 

 that one, up to and inclusive of riifimanus, it is readily dis- 

 tinguished by the abdomen. 



The females of this species and of latens are indistinguish- 

 able before abrasion, but when the scales have been removed 

 the prothoracic granules are distinctive. 



Mandalotus angustus, n. sp. 



o" (?). Black, antennas and tarsi reddish. Densely 

 clothed with light-greyish, feebly variegated scales, inter- 

 spersed with suberect setae; ciliation of tibiae inconspicuous. 



Rostrum but feebly dilated near apex, median carina 

 distinct throughout. Prothorax not much wider than long, 

 sides rather lightly rounded ; with numerous partially con- 

 cealed granules; with a vague median line. Elytra compara- 

 tively long, base conjointly arcuate and closely applied to 

 prothorax; with rows of large punctrfres, appearing very small 

 through clothing; interstices regularly convex. Basal segment 

 of abdomen almost flat in middle. Front coxa? moderately 

 separated, the dividing line between them less than half the 

 width of a coxa ; front tibiae lightly curved at apex. Length, 

 4-4 \ mm.
