and Species of Longicorn Coleoptera, 13 



Amnrygmns, extending from Australia to Java, and even India, 

 tliere were tliree or tour. 



Anthribidce, the most characteristic group of the Indian Archi- 

 pelago, seem to abound in Aru, there being not less than twenty- 

 four species in the collection ; it will be recollected that the 

 Ecelonerus b'ifascialus, Hope, is almost the only species of this 

 family which we obtain from Australia, Brentidce, too, were 

 tolerably numerous ; ten very interesting species being present. 

 The common Australian genus Belus was represented by a single 

 individual, which I believe is new. Among the Curculionidce, bl- 

 ades was the most numerous in species ; Orthorhynchus appeared 

 to be common in Aru as in Australia, although the number of 

 specimens was small ; Mecopus was also frequent. Of the splendid 

 Papuan Eupholi there were only two species, one of which, from 

 Key, was new ; they are probably excessively local. 



The most abundant of the Australian longicorn genera, whetl)er 

 in species or in individuals, Phoracantha, was represented by a 

 single specimen of P. b'igultata, Don, ; another longicorn also 

 common to both countries was Monohammus holotephrus, Bois. 

 Of other hitherto purely Australian genera belonging to this 

 great order (of which there were 109 species in the collection), 

 Penthea and Symphyletes alone were represented — that is, if the 

 Zygocera published by Mr, Thomson be a true species of that 

 genus : on the other hand, there was a considerable accession of 

 species to many Indian forms, e. g. Merioncsda, lolea, Driopea, 

 Cacia, Gyaritus, Phbjarus, Cereopsius, Praonetha, Ropica, &c. Of 

 the Papuan Tmesisternus there was not less than twenty species. 

 Among other described species belonging to this order were 

 Monohammus scabrosus, 01. ; Macrotoma LuzoJiica, F. ; Calli- 

 chroma Dorycus, Bois. ; Clyius gluucimts, Bois, ; C Australis, 

 Bois. ; Cylindnpomus nigro-fasc'iatus, Bois, ; Cada Van'ikorensis, 

 Bois. ; Glenea viridinotata, Bl. ; and several Tmcsisterni,* includ- 

 ing the splendid Sphingnotus mirabilis, Bois. By far, however, 

 the finest insect in the collection was a noble Batocera, which, 

 with its antennae, was not less than ten inches in length ; this has 

 been most worthily dedicated to Mr. Wallace, 



There were five Endomychidce, a family which is not^ as yet, 

 known to occur in Australia. 



* RIy genus Airhenutus {ante, vol, iv. p. 242), proposed on the supposition of 

 Sphingnotus miiahilis being a true Tmeiisternus, the only one with which 1 was 

 then acquainted, being erroneous, Arrhenotus must be cancelled, and its species, 

 WiiUacei, be refeired to Tmeiisleruus.
