Classification of the Colmptcroiis family Dynastidx. 323 



groujD consists of smaller species of rather varied form and 

 is apparently confined to Tropical Asia. The type species 

 is Hdcronyelius piceus, F. (= Fhileurus dctradus, Walk.), 

 and I refer to it also //. cribratelhcs, Fairm., H. jjauper, 

 Burm. {= H. simplex, Waterh. and H. inter ruptus, Fairm.) 

 and the following new species : 



AlissonotiLin crassioni, sp. n. 



Robustuni, ovatum, nigrum aut nigro-piceum, capite crebre 

 pimctato-rugoso, fronte sat I'ortiter bituberculato ; prothorace fortiter 

 et crebre punctate, medio loevius, disco antice laavissime impresso et 

 tuberculato ; scutello impunctato ; elytria fortiter striatis, stria prima 

 vix punctata, caeteris grosse irregulariter punctatis, interstitio prime 

 confuse punctato, 3° et 5° partim seriato-punctatis, lateribus minute, 

 apicibus grosse et crebre, punctatis ; propygidio leviter rugoso, postice 

 medio producto ; pygidio parce punctato. 



Long. 19-21 mm. Lat. max. 11 mm.

This is a large, black, oval insect. The head is coarsely 

 rugose and bituberciilate above. The prothorax is closely 

 punctured, the punctures being coarse except along the 

 middle^ where they are fewer and finer. There is a faint 

 impression near the middle of the anterior margin and a 

 minute elevation in front of it. Tlie scutellum is broad and 

 smooth. The elytra are deeply striated, the sutural stria 

 being scarcely punctured and the remainder rather strongly. 

 The first interval is very broad and irregularly punctured 

 and the Srd and 5th have each an incomplete line of 

 punctures. The outer margins are finely, and the extremi- 

 ties coarsely, punctured. The propygidium is produced in 

 the middle and bears two long and finely striated files. 

 The remainder of the surface is finely rugose and pubes- 

 cent. The pygidium is rather finely punctured. The 

 sexes are alike. 



Alissonotum imptressicolle, sp. n. 



Ovatum, nigrum, nitidum, capite crebre rugoso, bituberculato ; 

 prothorace fortiter baud dense punctato, medio subtilius, antice 

 Isevissime impresso et elevato ; scutello impunctato ; elytris fortiter 

 punctato-striatis, striae primas punctis toto confluentibus, interstitio 

 primo irregulariter, 3° et 5° lineare, punctatis, lateribus et apicibus
