punctures smaller ; the fourtli abdominal segment is narrow across 

 middle ; fovea almost without traces of lateral extensions. 

 Length 5^ — 6;^ mm.

The scutellum varies from entirely (extreme base 

 excepted) red to entirely black, the elytral markings have 

 a greenish or bluish gloss. In the only male before me 

 the base of the head and an irregular median prothoracic 

 vitta are black, in one female these parts are also dark, but 

 in six others both head and prothorax are of uniform 

 colour. In several of the females only the third tarsal 

 joint is black. 



I have referred this and the following species to Crypto- 

 cephalus, although the apex of the prosternum is not 

 bilobed, as they are typical-looking species of that genus. 

 In build they much resemble rubimindus, n. sp. The 

 markings of the present species are somewhat as in Id. 

 hynoci, Saund., but the punctures, antennae, scutellar 

 notch, etc., are different and the body is rather more 

 elongate. One specimen is marked as from the Western 

 Interior of S. Australia. 



Cryptocephalus minusculus, n. sp. 

 (Plate XXIII, figs. 70, 77, 78, 79, 80.) 



1^. Testaceous-red ; base of head, scutellum and metasternum 

 black ; elytra black with red markings, or red with black markings ; 

 apical portions of antenniB, abdomen (except at apex), tarsi, posterior 

 femora and apex of tibipe infuscate. 



Length 3(9 3|) mm. 



Much the build of the preceding species but the sexes always 

 smaller, the punctures smaller and (especially on elytra) more 

 numerous, the subhumeral lobes larger, the scutellum less transverse 

 with the base considerably wider than the apex.

This is a decidedly variable species. The head is 

 entirely red in the female and sometimes in the male also, 

 sometimes but two or three joints of the antennae, at 

 others all beyond the fourth are infuscate, sometimes all 

 the femora are red whilst in others the hind or the four 

 hind are infuscate, the scutellum is usually red but occa- 

 sionally black, in some specimens the abdomen is entirely 

 red. In some specimens the elytral markings (except that
