Cryptocephalus confinis, n. sp. 



9 . Head, antennfe, scutellum, metasternum, middle of base of 

 first abdominal segment and legs, black ; elytra metallic blue ; 

 elsewhere red. 



Head densely and coarsely punctate, especially at sides, an 

 impunctate (or feebly punctate) line down middle. Antennae thin, 

 slightly shorter than body, second joint less than half the length of 

 third, third and fifth very slightly longer than fourth, the others 

 gradually decreasing in length. Prothorax more than twice as wide 

 as long ; with rather large irregularly distributed punctures ; oblique 

 impressions rathA deep and wide ; margins narrow. Scutellum 

 almost equilateral! y triangular ; impunctate ; base rather deeply 

 notched. Elytra with subhumeral lobes of moderate size ; basal 

 two thirds with large punctures and with transverse rugulosities, 

 apical third with much smaller punctures subseriately arranged. 

 Apex of prosternum obtusely bilobed. Fourth segment of abdomen 

 curved at apex but not interrupted by fovea ; the latter with feeble 

 lateral extensions. 



Length 4| mm. 



Hah. N. S. Wales : Jenolan {J. C. Wiburd). 



A second specimen differs in having the lower half of 

 the face, the whole of the under-surface, and the coxjb 

 and trochanters reddish. 



The species differs from Cr. cyanipennis, Saund., and its 

 varieties in having the prothorax with much denser 

 punctures, the antennae much thinner and the elytral 

 punctures different. This and the four following species 

 belong to one of the most difficult sections of the genus. 



Cryptocephalus mediocris, n. sp. 

 (Plate XXV, fig. 167.) 



9 . Briefly oblong. Black, head (base excepted), antennae (fifth 

 and sixth joints infuscate, the seventh to eleventh blackish) ; pro- 

 thorax (extreme base black), under-surface and legs (tarsi more or 

 less infuscate) reddish. Pygidium and parts of under-surface with 

 short sparse golden pubescence. 



Head with rather small scattered punctures, but densely strigose 

 at sides of and behind eyes. Antenna? thin, not extending to 

 apex, second joint about half the length of third, third sliglitly 

 shorter than fifth. Prothorax rather more than twice as wide as 

 long ; with rather large irregularly distributed punctures ; oblique 

 impressions rather shallow ; margins narrow. Sciitellnm transverse,
