Two examples of Mononychus viilpeculus taken May 31, 1885, 

 upon the flowers of Iris versicolor, had fed upon the pollen of 

 that plant, and also upon leaf tissue, — the latter recognizable by 

 the abundance of spiral vessels. 



Two examples of Rhinonctis })yrrhopiiS obtained at Normal in 

 September of 1880, had nothing in the crop, but there was a con- 

 siderable quantity of food in the intestine, — unquestionably leaf 

 tissue, as shown by the numerous bundles of minute spiral vessels 

 distributed through the fragments. 



One of the nut weevils, Balaninus uniformis, a small sf)ecies 

 with a long and slender snout, contained but little food, and that 

 the mycelium of one of the black, incrusting fungi belonging to 

 the Sphfereacei, — probably Fumago. 



Ten other specimens, four of which were sent me by Dr. Kiley 

 and the remainder by Mr. O. S. Westcott, contained no traces of 

 food in the alimentary canal, and I consequently think it proba- 

 ble that these long- snouted beetles may be found to take fluid food 

 most commonly. The dissection of fresh beetles will be necessary 

 to determine this point.
