154 Mr. G. J. Arrow on the 



broad excavation. The female has two very inconspicuous 

 tubercles behind the middle of the front margin of the pro- 

 thorax. The species has already been described at greater 

 length by Fairmaire. 



The identity of Oryctes ingens, Kolbe, and Dimyxus cram- 

 peli, Fairm., with Oryctes cristatus, Voll., has been pointed 

 out by Messrs. Sternberg and Felsche. It has not been 

 noticed, however, that a still older name exists, viz. Oryctes 

 gigas, Cast. 



Herr Sternberg has rigbtly distinguished Xyloryctes tele- 

 phus, Burm., and ensifer, Bates (which he has renamed 

 X. laevipennis), which were not properly discriminated by 

 Bates, who attributed both to tlie same localities. The 

 examples of X. telephus in our collection are from Jalapa and 

 Oaxaca, while X. ensifer has been brought from Jalapa, 

 Cordova, Chiapas, Omilteme, S. Luis Potosi, and also from 

 Chuipache, Quezaltenango (Guatemala). 



In the ' Fauna of India, Lamellicornia,' lately published, I 

 have referred to Dipelicus the species described as Horonotus 

 and Camelonotus. H. deiphobus, Sharp, forms a connecting- 

 link between the larger well-punctured species represented 

 by D. cantori, Hope, and the smaller smooth forms of the 

 montrouzieri group. The actual habitat of D. deiphobus was 

 unknown to Sharp, but specimens from the Philippine Islands 

 were determined by Waterhouse by comparison with a 

 typical example from Dejean^s collection, and I have lately 

 received it from Sarawak, Borneo. 



D. cantori was described from a female supposed to have 

 come from China, but the type in the British Museum 

 ajDpears to agree sufficiently with that of the Javan species 

 described and figured under that name by Waterhouse. The 

 following is closely related: —
