 Boston.) 



Gives an elaborate and detailed description of Ihe fossil named, and then dis- 

 cusses its relations and concludes that Mormolucoides is probably the larva 

 of a Sialidan neuropteron. 



It has special interest from the fact that it is the oldest known insect larva.

While much fuller in the modern orders and families, these pages represent the 

 English text furnished to Dr. Zittel for his Handbuch der Palteontoiogie, 

 where the section forms the closing pages of the second part of the first 

 volume (pp. 7-21-S31), and is accompanied by more than two hundred illus- 

 trations. 



The present bulletin is issued with the concurrence of Dr. Zittel and the pub- 

 lisher of the Handbuch for the convenience of English readers. A French 

 version, under the auspices of M. Barrols, is also in course of simultaneous 

 publication. The present is its origiual form and is the authoritative 

 English edition.
