The tribe Elaterini is characterized by the larvae (Fig. 8) 

 having the "nasale" unidentate; the ninth abdominal segment 

 ending in a conspicuous spine; the transverse muscular impres- 

 sions on the abdominal tergites very conspicuous.

The tribe Physorrhini is tentatively maintained to receive 

 Anchastus. This tribe has been recognized by the leading 

 authorities in this group and I have not had opportunity of 

 examining positively determined larvae. A larva tentatively 

 determined as Anchastus bears strong resemblance to the larva 

 of Dolopius.
