375. Elytra and prothoracic margins yellow (llx3'5 mm.) — 



signata, Kerr. 



Note. — I have identified signata as a species taken 

 lately by Mr. J. Dixon, of Melbourne, in the north- 

 west district of Victoria. The description is merely 

 confined to colour and size. If I am correct, the 

 species often has the anterior fascia broken up into 

 spots, while the yellow colour so much predominates 

 over the green that it can scarcely be said to be 

 "vert obscur, avec de." The same species has been 

 determined by Blackburn for a specimen in the South 

 Australian Museum as disti nr/uenda . Saund., of 

 which it may be a variety. 



37(5-398. Anterior fascia often (or always) broken up into 3 spots. 



377-389. Apical mark covering apex of elytra. 



378-388. Prothorax concolorous, abdomen dark. 



379. Apices clearly bispinose, spines equal, elytra red with 



green fasciae — delectabilis, Hope. 

 380-387. Apices acuminate, with narrow oblique excision. 

 381. Base of prothorax with pronounced medial lobe — 



obscura, Saund. ; var. transversipicta, Thorns. 

 382-387. Base of prothorax nearly straight, form cylindric. 

 383. Elytra orange-red, pronotum bronze — recta, Saund. 



384-388. Elvtra testaceous. 

 385-387. Elytral intervals flat, 



380. Pronotum and fasciae blue-black, anterior spots not in a 



horizontal line (11 mm. long) — atricollis, Saund- 



387. Pronotum and fasciae bright-blue, anterior spots in a 



horizontal line (8-9 mm. long) — deserti, Blackb. 



388. Elytral intervals convex, apices more widely excised — 



suavis, Kerr. 



389. Abdomen yellow, size large (16-19 mm. long) — alexandri, 



n. sp. 

 390-398. Subapical mark not at the apex of elytra. 

 391-393. Margins of elytra sanguineous. 



392. Intervals flat, suture partly dark, markings blue — 



rubrocincta, Gehin. 



393. Alternate intervals subcostate, suture dark throughout, 



markings bright-green- -altemecosta, Thorns. ; alacris, 



Kerr.; quadrinotata, Blackb. 

 394-398. Margins of elytra not sanguineous. 

 395-397. Pronotum bronze. 



396. Posterior half of suture dark — piliventris, Saund. 



"397. Whole suture dark — crux, Saund. 



Note. — I have not been able to identify this species, 



which must be very close to several of its neighbours, 



and possibly a variety of piliventris. 

 398. Pronotum green or blue, whole suture dark — scalaris, 



Boisd. ; cyanicollis, Boisd. ; siibtrifasciata, C. and G. ; 



media, Hope; crucigera, C. and G. ; prvdens, Kerr. 

 399-420. Anterior fascia bifurcate laterally, leaving lateral spot 



yellow or red. 

 400-409. Yellow or red postbasal marks continuous with lateral 



spot. 



401. Form elongate, flat, elytra red, apices simple (19-23 mm. 



long) — insvlaris, Blackb. 



402. Form subcylindric, elytra yellow, apices bispinose (15-16 



mm. long) — bwwni, n. sp.
