147. Abdomen dark, elytral intervals nearly flat — victoriensis, 



Blackb. ; sensitiva, Kerr. 



148. Abdomen yellow, elytral alternate intervals subcostate — 



costipennis, Saund. 

 149-154. Elytra with marginal and 6 discal spots yellow, abdomen 



dark. 

 150-152. Prothorax concolorous. 



151. Pronotum with medial sulcus — mansueta. Kerr. 



152. Pronotum without medial sulcus, prothorax globose — 



laenii. Thorns. ; var. electa, Kerr. 



153. Prothorax and elytra with red margins, elytra with 



humeral and 2 basal spots and 2 fasciae yellow - 

 rufolimbata, n. sp. 



154. Prothorax purple with bright-green margins, elytra 



with 4 marginal and 6 discal spots yellow — versicolor, 



C. and G. ; decemguttata, Gory; parva, Saund. 

 155-166. Head with yellow spot, prothorax with yellow or red 



margins, underside mostly yellow. 

 156-165. Apices of elytra trispinose, posterior margins entire. 

 157-161. Elytra with epipleural and 8 discal spots yellow. 

 158. Form ovate and obese — octospilota, C. and G. ; femorato. 



C. and G. ; adelaidae, Hope; (var.) r-ufipes, Macl. 

 159-164. Form parallel. 



160. Basal spots more or less round — decemmaculata, Kirov ; 



inaequalis, Kerr. 



161. Basal spots elongate linear — picta, C. and G. ; purpurea, 



Hope ; var. laetabilis, Kerr. 

 162-166. Elytra with epipleural and 6 discal spots yellow or red, 

 underside yellow. 



163. Apex and margins of elytra red, apices bluntly tridentate 



— pallidiventris, C. and G. ; var. cincta, Blackb. ; 

 rubrocinctd, Kerr. 



Note. — The only distinctions I can find between 

 cincta and pallidiventris are the larger size and the 

 antemedial dark fascia continuous to the sides in the 

 former . 



164. Apex of elytra dark, apices acutely trispinose — elderi, 



Blackb.; (margins of elytra sometimes reddish) 

 rustica, Kerr; diversa, Kerr. 



165. Form oblong-attenuate, elytra with large basal and 



apical -spots and postmedial fascia brick-red, femora 

 red — argillacca, n. sp. 



166. Apices of elytra bispinose, posterior margins serrated — 



serratipennis, n. sp. 



Note. — Octospilota, elongatula* crocicolor, and 

 others of this group have a tendency to longitudinal 

 confluence of the elytral yellow markings. Of octo- 

 spilota there is a common variety from Perth, Wes- 

 tern Australia, in which the basal and medial spots 

 coalesce, also the postmedial and subapical, leaving 

 the margins, suture, and one fascia dark. JRufipes, 

 Macl., is a well-marked Queensland variety, with red 

 femora and distinctions in the pattern. The name 

 should be kept. 



T have a specimen of elongutula. from Sydney, in 



. which all the spots on each elytron have thus 



coalesced, so that the dark markings consist only of 



a marginal and a sutural vitta. thus approaching 



<but distinguished from) vittata, Saund.
