 occurring in most of the Indo-Malayan islands, and in India,. 

 Burma, and China. 



Phileurus convexus, Arrow, sp.n. 



P. nitidus, angustus, hand depressus ; capite rugose punctato, 

 acuminato, fronte cornu parvo conico armata ; prothorace sub- 

 quadrato parum transverse, angulis posticis fere rectis, antici& 

 parum approximatis, disco leviter punctato, lateribus paulo 

 crebrius, medio antice et postice carinas vestigiis vix apparentibus ; 

 elytris longis, grosse lineato - punctatis, interstitiis minutissime 

 punctatis ; abdomine cum pygidio fere polito, propygidio coriaceo.

Hah. — Flying Fish Cove. 



This new species is formed for the first representative of the 

 important family Dynastidse so far found in the island, a single 

 specimen having been recently discovered by Mr. H. Ross. 



This species is less flattened, and somewhat longer than usual, 

 but does not differ structurally from the larger described forms 

 of Continental Asia, where all its hitherto known allies are found, 

 for the Ceylon insect described by Walker is evidently wrongly 

 placed. M. Fairmaire has referred to a *P. javamis,'' apparently 

 the Heteronychus javanus, Burm., which although allied is hardly 

 congeneric. But the genus Phileurus will probably be eventually 

 restricted to the American insects and new genera formed for the 

 Oriental species. 



The only other insect new to the island is a large moth : Patula 

 macrops (Linn.), (Syst. IS'at., 12th ed., iii, p. 225). Africa^ 

 Madagascar, Ceylon, India, Burmah.
