ADDENDA 



Page 15, footnote 20. For the entire footnote as it stands read : 

 Tlie .systematic position of this series is uncertain. Its larval form 

 approaches in important characters the larvae of the cucujoid fam- 

 ily Oedemeridae but also appears to converge toward the larval 

 form of the ancient suborder Archostemata. Giving serial rank to 

 the group is in accord with the generally accepted views in regard 

 to its phylogeny but from the larval form it could wdth equal riglits 

 be considered a mere family, Lymexylidae, of the series Gucujoidea. 

 This latter classification can be expressed by altering and somewhat 

 simplifying the parts of the keys relevant to the matter in the fol- 

 lowing way : 



First alteration 



Page 12. For section 10 as it stands read : 



10. Distinct gula or gular structure present or absent ; when 

 absent, with mandibles possessing mola, or lacinia 

 mandibular or retinaculum, or a long brush of hairs 

 posteriorly on the inner margin, or extraordinary 



structures, except a pseudomola 11 



Distinct gula or gular suture always absent, mandible 



either simple or posse.ssing a pseudomola 20 



Second (ilfrration 



Page 14. For section 18 as it stands read : 



18. Ventral mouthparts as a rule retracted ; when pro- 

 tracted^' possessing a mandible with either molar 



part, or retinaculum, or other appendices 19 



Ventral mouthparts always protracted; mandible al- 

 ways simple without molar part, retinaculum or other 

 appendices. (Head-capsule closed posteriorly by a 

 broad, transverse bridge separating the subfacial 



region of head from ventral region of prothorax) 



Ceramhycoideo (p. HO) 

 (except cerambycoid 

 subfamily D i s t e n i- 

 inae, p. 15, line 4 and 

 p. 62.)
