320 APPENDIX. 



C. impressa is a variable and rather widely distiibuted species, 



occurring in most of the lndo-!Malayan islands, and in India, 

 Burma, and China. 



PMleurus eonvexus, Arrow, sp.n. 



P. nitidus, angustus, hand depi'essus ; capite rugose punctato, 

 ucuminato, fronte cornu parvo conico arraata ; prothorace sub- 

 quadrato parum transverso, angulis posticis fere rectis, anticis 

 parum approximatis, disco leviter punctato, lateribus paulo 

 crebrius, medio antiee et postice carinse vestigiis vix apparentibus ; 

 elytris longis, grosse lineato - punctatis, interstitiis minutissime 

 punctatis ; abdomine cum pygidio fere polito, propygidio coriaceo.

This new species is formed for the first representative of the 

 important family Dynastidoe 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. jacanus,'' apparently 

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

 congeneric. But the genus PMleurus 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. Nat., 12th ed., iii, p. 225). Africa, 

 Madagascar, Ceylon, India, Burmah.
