rounded, its puiicturation sparse on the disc but becoming close 

 and coarser towards the sides. The antennae are thinly clothed 

 with long fine hairs. 



Port Lincoln ; under stones. 



N.B. — Some smaller specimens (long, li lines, vix), with 

 puncturation slightly coarser throughout, and antennae and palpi 

 scarcely infuscate towards the apex are probably to be regarded as 

 a mere variation, — or possibly pertain to the other sex. 



Rhinobgltjs, gen.nov. 



Corpus oblongum ; supra glabrum ; subtus pilis adpressis parce 

 vestitum. Caput verticale, usque ad oculos thoraci insertum, 

 antice sat cylindricum subrostriforme. Oculi sat magni, rotun- 

 dati, sat convexi, minus fortiter granulati. Antennae corporis 

 dimidio pauUo longiores, medio graciles, apicem versus minus 

 incrassatae. Prothorax sat convexus, antice medio fortiter pro- 

 minens, lateribus integris. Scutellum transversum, sat parvum. 

 Presternum inter coxas sat latum, postice truncatum dilatatum, 

 episternis antice baud convexis. Femora inermia, medio minus 

 dilatata. Tibiae simplices, modice robustae, apice externo minus 

 dentate. Tarsi S3.t robusti (posticis manifeste longioribus graci- 

 lioribus), articulo 3° profunde bilobo, posticorum articulo primo 

 secundo vix longiori. Unguiculi appendiculati, divaricati. Labrum 

 magnum. Mandibula porrecta. 



This appears to be an extremely anomalous genus and I am 

 quite unable to specify any other as being its near ally. I do not, 

 however, observe any character suggesting a doubt of its belonging 

 to the Eu7nolpid(E (of which it has quite the facies) except that 

 its antennae are not quite so widely separated at the base as is 

 usual in the family. But I believe this to be merely an accidental 

 discrepancy connected with the very peculiar form of the head. 

 This organ is produced into a short wide thick beak, with parallel 

 sides, extending forward beyond the base of the antennae slightly
