362 INSECTA MADERENSIA. 



sato, sed in specie singula (fortasse huic generi vix referenda) (^'^11. 3 a) gracillimae, scapo sub- 

 recto et ad apiccrn subito clavato (ut in Laparocero) ; fiiniculo 7-articulato, articulis obconicis, 

 priino et sccuiido longiusculis (modo hoc, niodo illo longiore), reliquis longitudine decrescentibus; 

 clava elongato-obovata, distincte tri- (fortasse quadri-) articulata. Pedes (typice) in maribus 

 crassiusculi, in focminis graciliores sed vix brcviores : tibiis omnibus pilosissimis et apice obscure 

 setuloso-ciliatis, in fceminis nee intus crenulatis nee ad apicem uncinatis ; antcrioribus in maribus 

 ad apicem internum in uncum (in anticis plerumque obsoletum, sed in intermcdiis sa;pius 

 distincte observandum, — necnon in omnibus pilis setisquc celatum) inflexum productis ; anticis 

 in utroque sexu (VII. 5 6, 5 b*), sed prsesertim in masculo (VII. 5 b), apice incurvis, necnon 

 in hoc sexu intus plus minusvc obscurissime (interdum, oculo inarmato, vix perspicue) 

 crenulatisj subtus apicem versus plus minusve leviter subconcavo-emarginatis atque ad apicem 

 ipsum \ix subgaleiformibus ; intei-mediis in utroque sexu, sed prsesertim in foemineo, rectis ; 

 posticis in utroque sexu rectis, in foemineo (VII. 5 c) simplicibus, — in speciebus aberrantibus 

 ctiam in masculo simplicibus, sed in typicis (VII. 5*) apice valdc dilatatis et lateraliter 

 introrsum exsecatis, ad apicem internum plus minusve lamellato-productis et oblique trun- 

 catis (calcaneum mox pone apicem ipsum plus minusve exstantem et acutum efficientibus) ; 

 necnon ad externum in angulum ])lcrumque acutum et valdissime exstantem explanatis : iarsis 

 pilosissimis. 



Typus — Atlantis lamelHpes. (T.vn. VII. fig. 5.) 



The somewhat dissimilar si^ecics which I have inchuled under the present genus 

 are insects of extremely difficult location ; and it is probable that at least thi'ee 

 distinct modifications of form are indicated amongst tliem. Being unwilling 

 however to create too many genera in this obscure department of the CurcHlio/iidie, 

 I have been content to distrilnite them into sections, — which, it will be perceived, 

 arc gradually more and more removed, both in size and structure, from the larger 

 Madeiran tj^jio until they are almost merged into Oniias. Seeing therefore that I 

 woidd merely adopt this adjustment as a provisional one, it is scarcely necessary 

 to remark, that I Avould only regard the A. lamellipes, calcatrLv, noctkagans, 

 laiiripotens, australis, vespertimis and lanatits as normal AtlantkJes, believing that 

 they are sufficiently defined to be altogether isolated from the remainder. The 

 A. clavatus indeed, from the peculiar construction of its antenna?, I should rather 

 have referred to Lnparoccrus, but, not having been able hitherto to procui'e a male 

 specimen for comparison, I have thought it safer, since the sexes of that genus are 

 so exceedingly well-defined, to keep it in its present doubtful position, where it is 

 necessarily free for removal to wherever future investigations may render de- 

 su'ablc : at the same time I may add that it seems far from improbable that it Avill 

 be eventually found to constitute another centre of radiation of equal value with 

 Ciiphoscelis and Atlantis propo'. Touching the smaller members of the group, 

 which, for the sake of convenience, and to obviate as far as is consistent the neces- 

 sity for multiplying genera, I have termed aberrant Atlantides, it may be enough 

 to state that they also, in their unpilose elytra, almost equally robust legs in both 

 sexes, and in the undilated and nearly unarmed tibite of their males, would appear 

 to merit I'cmoval from the rest ; nevertheless, for the reasons above assigned, I
