to tenth joints more or less acutely serrated. Prothorax

 distinct. Elytra slightly wider tliau prothorax, sides and 

 suture (except on basal t'ourthj thickened ; with dense and 

 fairly large punctures, smaller about base and apex than 

 elsewhere. Legs long ; front trochanters subtriangnlarly 

 produced ; front femora semicircularly notched near apex, 

 front tibiae rather strongly curved at base, and but little 

 more tlian half the length of hind pair ; second and third 

 joints of tarsi very short.

In general appearance fairly close to dispar and violaceiis, 

 but front legs, antennae, and punctures very ditfereut. The 

 front legs are somewhat as in. pulcherrimus and dentipes, but 

 the elytra are very differently coloured. In my table of the 

 genus * it would be associated witb mirabUis, whose elytra 

 are pale at the base as well as at the a])ex. Scarcely more 

 than the thickened apical margins are pale.

Mr. Bryant has sent two specimens (sexes) from Baan Baa 

 (New South Wales) that appear to represent a variet}'^ of 

 this species. They diH'er from the typical forms in being 

 slightly larger, rather hairier, the markings more purplish, 

 the front tibiae black on their basal external edge, and the 

 prothorax with an irregular dark triangle extending from 

 the base to near the middle.
