Australian and Tasmanian Gryi^toccphalides. 407 



From larinus, n. sp., the female differs in being smaller, 

 with the fourth abdominal segment smaller, the shoulders 

 black and the under-surface entirely pallid. From Cadmus 

 sculptilis, Chp. (which is certainly congeneric), it differs in 

 its legs and the apical impression of the male ; in that 

 species the impression is fairly large transverse and 

 very highly polished. 



Cryptocephalus sobrinus, n. sp. 



^ . Testaceous ; junction of pro thorax with scutelhim and elytra, 

 a narrow facial streak and punctures of upper surface more or less 

 stained with brown ; the punctures at base of elytra and on pro- 

 thorax darker than elsewhere. 



Head rather densely and coarsely punctate, the piinctures more 

 or less confluent posteriorly ; median line feebly impressed. An- 

 tennae thin, second joint about one-third the length of third, third 

 shorter than fifth. Prothorax regularly convex, with almost 

 regularly distributed and moderately large punctures, smaller on 

 disc and base than elsewhere, and with rather numerous minute 

 scattered punctures ; oblique impressions feeble ; margins narrow. 

 Scutellum transverse, apex not much narrower than base, base feebly 

 notched. Elytra oblong, subhumeral lobes feeble ; with round, 

 moderately large, more or less regular punctures, becoming smaller 

 and subseriate in arrangement posteriorly. Apex of prosternvAn 

 very wide and very feebly bilobed. Intermediate segments of 

 abdomen strongly incurved to but continuous across middle, fifth 

 large, middle of apex deeply and almost semicircularly excised. 



Length 5 mm. 



$ . Differs in being larger, second and third segments of abdomen 

 rather large and with straight sutures, fourth just traceable across 

 middle ; fovea without lateral extensions. 



Length 6| mm. 



Hah. Queensland (types in Aug. Simson's collection). 



The scutellum in the male is impunctate but in the 

 female is impressed with a few scattered punctures. The 

 antennae in both specimens are broken, but in the male 

 eight joints remain and these are uniformly pallid. 



The decidedly emarginate apical segment of abdomen in 

 the male readily distinguishes this from Or. pmcilodcrmus, 

 Chp., Cad. sadptilis, Chp., and from any of the preceding 

 species.
