1916] Williams — Life-History of Methoca Stygia Say 125 



Great opportunities await the biologist who is interested in these 

 singular insects and who has access to their haunts. More com- 

 plete field observations and careful methods of confinement will 

 surely furnish a better knowledge of the habits and early stages 

 of our own rare species. 



I am indebted to Mr. C. W. Johnson of the Boston Society of 

 Natural History, and to Prof. W. M. Wheeler and Prof. C. T. 

 Brues of Harvard Uni^•ersity for the loan of material.
