406 Mr. A. M. Lea's Notes on 



Cryptocephalus stenocerus, n. sp. 



$ . Pale reddish-testaceous, elytra flavons ; extreme base of head, 

 junction of prothorax with scutelluni and elytra, suture and shoulders 

 black ; elytral punctures deeply stained with black ; antennte feebly, 

 the tarsi and apex of tibise moderately infuscate. 



Head densely and moderately coarsely punctate, punctures more 

 or less confluent towards base ; with a distinct median line. Antennae 

 long and thin considerably passing apex of body, second joint sub- 

 globular, less than one-third the length of third, third distinctly 

 shorter than fifth, eleventh slightly shorter than tenth. Prothorax 

 more than twice as wide as long, regularly convex ; with compara- 

 tively small and not dense punctures, and with minute scattered 

 punctures ; oblique impressions very feeble ; margins very narrow 

 and entire, ticutellum, strongly transverse, apex not much narrower 

 than base, base almost entire. Elytra with small subhumeral lobes ; 

 with rather small and not very dense punctures, becoming smaller 

 and seriate in arrangement posteriorly, basal portion almost without 

 transverse rugulosities. Apex oiprosternum wide and just perceptibly 

 bilobed. Abdomen with intermediate segments strongly incurved 

 to but continuous across middle, fifth large, with a fairly wide, 

 shallow, simple depression. 



Length 5 mm. 



§ . Diff'ers in having the elytral punctures stained with chocolate 

 brown, the antennae just passing apex of body, abdomen with almost 

 straight sutures to the second and third segments and the fourth 

 traceable across middle ; fovea with shallow lateral extensions. 



Length 6 mm. 



Hob. Queensland: Rockhampton (types in Macleay 

 Museum). 



In both specimens there is a narrow infuscate facial 

 streak, but it is scarcely traceable in the female ; on the 

 prothorax of the female the punctures are moderately 

 stained, whilst in the male but very few of them are even 

 slightly stained. The punctures of the elytra being much 

 darker than those of the prothorax (instead of vice versa) 

 should readily distinguish this species from its close allies. 

 Seen from behind the elytra appear to be supplied with 

 regular black lines. 



Can be readily distinguished from Or. jjceciloderinus, 

 Chp,, and the preceding species, by the abdomen of the 

 male having the fourth segment distinct (although narrow) 

 across the middle and the fifth with the depression much 

 smaller and narrower ; the antennae also are different.
