This conclusion is strengthened by the systematic arrangement 

 of these insects as conceived by the more eminent workers of 

 the group and based almost exclusively on adult characters. 



The first, third and fourth tribes of Candeze (1857)* 

 Agrypnides, Hemirhipides, Chalcolepidides, fall naturally under 

 my Pyrophorini. His second tribe, Melanactides, is still unknown 

 in the larval stage and we can expect much light to be thrown 

 upon its phyletic position when the larvae arc described. 

 Candeze states that the tribe serves as a connecting link between 

 the Agrj^pnides and the Hemirhipides. The type genus of 

 the tribe was established by LeConte (1853) for several North 

 American species placed by Eschscholtz in his Liidius and 

 by Germar in Pristilophiis, both genera now usually considered 

 as Corymhites Latr. Whether the larvae of these insects will 

 show a relationship between my tribes Pyrophorini and Lep- 

 turoidini or will reduce the tribe Melanactides to synonomy 

 under one of the other tribes, remains to be discovered. He 

 includes in his seventh tribe, Elatcrides vrais, the Pyrophorina 

 and Monocrcpidina, which I consider should be placed at the 

 end of the tribe Pyrophorini as the transient forms between 

 the two tribes of this subfamily, and not at all closely related 

 to the other subtribes which he places in this tribe. Excluding 

 these two groups of genera, the tribe Elatcrides vrais agrees 

 with the primary division of Schiodte and Henriksen, and may 

 have suggested the high ordinal value that these more recent 

 writers gave to the presence or absence of anal armature. 

 Candeze's division of his two great tribes into subtribes, how- 

 ever, is remarkably illuminating from our view point, in many 

 respects bearing out the conclusions here set forth. His subtribe 

 Ludites includes the tribes vSteatoderini and Agriotini of my 

 subfamily Elaterinae. His Campylites, which he places at the 

 end of his classification and considers very distinct from the 

 other tribes, I place at the end of the tribe Lepturoidini, though 

 undoubtedly many of the genera in the Campylites will be 

 found to belong in other tribes than that of the type genus. 

 In his later workf (1891) Candeze disregarded the two tribes 

 of his Monograph and raised all his subtribes to tribal rank.
