L. tinctus also has an infuscation on the elytra, of which there is 

 no mention in the description of amabilis. 



It seems desirable, in view of the additions that have been 

 made to the genus Litocriis since 1895, to furnish a revised 

 tabulation of the characters of the Australian species (omitting 

 amabilis^ Guilleb.), — as follows, — 



A. The lateral stria of the pronotum reaches the froat margin and there 

 ends. Basal joint of hind tarsi about three times length of second 

 joint. 

 B. Elytra without transverse sculpture. 

 C. Colour entirely testaceous 

 CC. Elytra dark, with well - defined light 

 markings 

 BB. Elytra with close transverse very fine 

 scratch-like sculpture ... 

 AA. Not combining the characters attributed to 

 'A." 

 B. Joint 8 of the antennoe notably larger than in 

 the species under " BB," and not transverse. 

 C. Joint 9 of the antennae scarcely wider than 

 long. Puncturation of elytral interstices 

 strong 

 CC. Joint 9 of antennae quite strongly trans- 

 verse. Puncturation of elytral interstices 

 very fine 

 BB. Joint 8 of antennse quite small, transverse. 

 C. Elytra with the second stria as strong as 

 the subsutural one, and quite different 

 from the others 

 CC. Elytra not as in frigidus. 

 D. Elytra without dorsal strife (though 

 usually with rows of punctures). 

 E. Alternate interstices of elytra (espe- 

 cially the first and seventh) with 

 rows of distant punctures). 

 F. The non-seriate puncturation of inter- 

 stices comparatively strong. 

 G. This puncturation very sparse and 

 irregular. Colour of elytra wholly 

 black 

 GG. This puncturation closer and 

 even. Elytra with large well- 

 defined pale markings 

 FF, The non-seriate puncturation on the 

 elytra much finer. 

 G. Under surface testaceous - red. 

 Elytra not uniformly black. 

 H. Joint 9 of antennse strongly 

 transverse, wide at base. 

 Form obtuse behind... 

 HH. Joint 9 of antenna less trans- 

 verse and much narrowed at 

 base. Form more narrowed 

 behind. 

 I. Upper surface non-iridescent ; 

 elytra dark, with a large 

 common red spot ... ... maculatus, Biackb.
