several Species of Bolboceras. 83 



emarginatus. Caput quinque-denticulatum, dentibus fere 

 asqualibus. Thorax subretusus, medio ternis tuberculis 

 armatus, interno minori. Elytra striato-punctata, corpus 

 infra flavum et valde tomentosum. 

 From the Swan River. 



Castaneous brown. Clypeus quadridentate. Head punctate 

 in front, smooth behind, with five nearly equal tubercles. Thorax 

 very shining, sparingly punctate, with three horns in the centre, 

 the middle one shortest, the lateral ones recurved, behind there is 

 an oblique glossy space, encircled with an irregular carina. Scu- 

 tellum glossy, punctate. Elytra pitchy brown, punctate-striate. 

 Anterior tibiae with five teeth. 



Mr. Kirby's species, B. Australasice, described in the Trans- 

 actions of the Linnsean Society (Vol. XII.), is a female, and from 

 its pale chesnut colour I should consider it as immature. The 

 male does not appear to be known. 



Note. — M. Gnerin Meneville has published the descriptions 

 of two species of this genus, from Swan River, in the 

 Magasin de Zoologie. (Insectes du Voyage de la 

 Favorite, p. 50, 51.) — Sec. E. S.
