affinities of the Dorcadiotihice appear to be cliiefly between the 

 Apomecytiincs and the Lamiints : the genus Blax showing a tendency 

 towards the Tmesislermnce. Several species betray a striking 

 resemblance to genera of the Curcul'wmdcs inhabiting the same 

 countries with themselves. 



The geographical distribution of the Dorcad'ionince is somewhat 

 peculiar, inasmuch as only one species {Taurorcus chabrillacii, 

 Thorns.) has as yet been found in South America, except Chili, 

 where Hoplonotus and Microclepies appear to be common. 

 Mexico and Texas have Moneilema and Echlliistatus, and Cali- 

 fornia has Ipochus, In Europe we have only two genera, Dorca- 

 dion and Parmena. Africa has some very remarkable forms, as, 

 for example, Oricethus, Opsies, Stenoparmena, Auxa, &c. (the last 

 from Madagascar). From Asia we may expect many novelties ; 

 at present we may mention Dorcadida, Morimnps'is, Plectnira and 

 Aconodes* Others in collections are not yet described. 



'J'here appear to be only two AustralTan genera — Microtrogus 

 and At/iemistus,-\ but there is reason to believe that they are both 

 numerous in species. New Zealand, so excessively poor in its 

 specific forms of animal life, is comparatively well represented. 

 Here, and peculiar to those islands, are Cercegidion, Hcxatiiclia, 

 Xijlotoles, and Somatidia, all isolated forms so far as New Zealand 

 is concerned, although the last is closely allied to the European 

 Parmena. Islands, and probably also mountain masses of low 

 elevation, appear to be particularly favourable to the existence of 

 members of this group. Thus from Madeira and the Desertas 

 we have Deucalion^ from the Canaries Lepromoris\; Lord Howe's 

 Island gives us Blax, and New Caledonia Tricondyludes. 



The species collected by Mr. Wallace form two 



Genera. 

 Prothorax toothed on each side anteriorly . Dasyerrus, n. g. 

 Prothorax unarmed ..... Bybe, n. g. 



* This genus is only known from one example (now in the British Museum). 

 It was found in th« Himalayas, near Darjeeling, I believe. There is another 

 form from the Neilgherries. The hill-districts of India have doubtless many 

 more. 



f I believe, however, that ray genus MesoUta will be eventually referred to 

 this sub-family.
