On Scarabasida? in the British Museum. 9 



II. — Scarabandai in the British Museum. — A Sixth 

 Contribution. By Charles O. Waterhouse. 



Onitis inuus, Fabr. 



Fabricius described two species by the name Scarabceus 

 sphinx, and to the earlier of these he afterwards gave the 

 name inuus. Harold, in the Munich Catalogue, has retained 

 the name sphinx, placing inuus as a synonym, and has been 

 followed in this by M. Lansberge, in his u Monograph " (Ann. 

 Soc. Ent. Belg. xviii. p. 89). The types ( <$ ? ) of this earlier 

 species are in the Banksian collection under the name inuus, 

 and from the figures given by Olivier I feel sure that these 

 specimens are those from which the drawings were made. 

 The male is not the species described as sphinx by Lansberge, 

 as there is no trace of the spine behind the anterior femora. 

 It has the uniform bronzy-green colour of 0. shoensis, Reiche. 

 The elytra are moderately strongly crenate-striate, with no 

 crenulation within the marginal carina. Theclypeal ridge is 

 very short and is a trifle nearer to the frontal ridge than to 

 the anterior margin ; the clypeus itself is rather finely punc- 

 tured, and is not granular as in many allied species. The 

 thorax is strongly punctured, but has a smooth median line. 

 The anterior femora have a small tooth (emarginate at its 

 apex) below on the anterior margin beyond the middle. The 

 anterior tibiae are quadridentate, and have five tubercles 

 below. The intermediate femora are unarmed. The poste- 

 rior femora have a strong, triangular, acute-pointed tooth 

 beyond the middle. The metasternum is nearly smooth and 

 is not channelled. 



The only specimen in the Museum collection which agrees 

 well with the type is one from Lake Nyassa ; this differs from 

 the type only in having some slight crenulations within the 

 lateral carina of the elytra near the apex ; but this is much 

 less on one side than on the other, and no doubt is a variable 

 character. 



The type female of 0. inuus is quite a different species, 

 and, as will be seen from Olivier's figure, is pubescent below. 

 This I have determined from Lansberge's Monograph to be 

 0. confusus, Bohem., ?. 



Onthophagus crassus } Sharp. 



Dr. Sharp describes this species from Laos and Cambodia, 

 and throws doubt on the habitat " Java " borne by the De- 

 jeanian example. The British Museum Collection has two 

 specimens of this species from Java.
