ocelli separated by nearly twice the distance between anterior and 

 posterior ocelli; orbits narrow, about one-sixth as wide as inter- 

 frontalia; orbital bristles short, 4 in number, hairs weak and sparse; 

 antennae small, third joint rounded in front; arista bare, slightly 

 swollen and pale at base, its length slightly greater than anterior 

 width of frons; cheek one-fourth as high as eye, marginal hairs

 cultural Experiment Station. Pp. 177-445, 44 plates. Ithaca, 

 N.Y., June, 1917. 



in this study Mr. Funkhouser has given us a valuable sum- 

 mary of his work on the Membracid fauna of the Cayuga Lake 

 Basin, together with an excellent introduction to the general study 

 of this attractive family. 



The first part of the paper contains a useful general descrip- 

 tion of the geology, physiography and climatology of the district, 

 and its characteristics as a faunal and floral area, followed by an 

 account of the local Membracid fauna, the distribution of which
