elytra having fewer tubercles, prothoracic sculpture less ver- 

 miculate, and scape stouter. The expression "tuberculis sub- 

 obsoletis" and "the alternate elytra! interstices are 

 obscurely knobby rather than distinctly tuberculate," would 

 be deceiving if applied to the co-type (although, no doubt, 

 correct for the type), as from it tubercles (except those on 

 and about the apical slojoe) and knobs are entirely absent, the 

 alternate interstices being feebly waved only. 



Leptops sculptus, Blackb. 



A single specimen from the North-west of South Aus- 

 tralia (H. Basedow) probably belongs to this species; it 

 differs, however, in being much smaller than the type (9 as 

 against 14 lines), v 18) but in all other respects it agrees with 

 the description. 



Leptops nitidivextris, n. sp. 

 PL 'xxxv., figs. 79 to 86. 



cS . Black. Densely clothed on legs and on depressed 

 parts with small round whitish or greyish scales, closely 

 applied to derm ; antennae and legs with numerous setae. 



Rostrum with intermediate carinae strongly elevated, 

 dilated at base, and suddenly terminated there, median 

 carina rather feeble and short; sublateral sulci narrow and 

 deep in front, dilated to near base, and then narrowed; 

 scrobes wide and deep at base, suddenly curved upwards so 

 as to margin the eyes. Antennae not very long; first joint 

 of funicle slightly longer than second, none of the others 

 transverse. Prothorax rather long, and roughly sculptured. 

 Scuteilum very small. Elytra long, at widest not twice the 

 width of prothorax ; with subgeminate rows of large punc- 

 tures, more or less interrupted by elevations; third, fifth, and 

 seventh interstices with conspicuous rows of tubercles, com- 

 mencing as obtuse elevations near the base and becoming 

 larger and conical posteriorly. Presternum with a conspicu- 

 ous tubercle in front of each coxa, and a semi-double one in 

 middle of base. Abdomen highly polished except at sides. 

 Legs long; tibia'e not denticulate. Length, excluding rostrum 

 (S , 9), 25-35 mm. 



9 . Differs in being larger, with much wider elytra 

 (especially posteriorly), longitudinal elevations of prothorax 

 less abrupt, tubercles more numerous and obtuse, and append- 

 ages shorter. 



(18) Much less than the range of variation of the allied 

 (contrarius.
