to the manner in which the pollen-baskets of the workers are 

 loaded, the structures concerned, and the supposed use of the 

 "wax-shears" are largely false. The marvelous modifications 

 of the worker's legs, apparently so well adapted to her various 

 functions, remain as marvelous as before, but they are em- 

 ployed in quite other ways than those in which they have been 

 believed to act. 



If such a revolution in the interpretation of the functions of 

 an insect so well known as the hive bee can take place in this 

 day and generation, how many other supposed facts may be 

 overturned as the commoner insects are more and more inten- 

 sively studied. This concrete case of the honey bee, as exem- 

 plified by Dr. Casteel's results, ought surely to be a warning to 

 those who hold that, because one investigator is engaged on a 

 certain piece of research, it is useless and a waste of time foi 

 another student to devote his time and energies to the same 

 subject.

The Harlequin Cabbage Bug in Iowa. (Hemip.). 



Being unable to find a record of the occurrence of Murgantva histri- 

 cnica Hahn, in Iowa, the following note may be of interest. 



In October, 1911, a male and a nymph of this species, the latter about 

 half grown, were found along a small creek near Iowa City by O. W. 

 Rosewall. There were several truck patches in the vicinity, in some of 

 which cabbage and other cruci ferae were grown, but no damage from 

 these bugs has yet been reported in this locality. 



Chittenden (Circular No. 103, U. S. Department of Agriculture, 

 Bureau of Entomology) says: "This species has obviously become dif- 

 fused from a central point of dispersal, Mexico, chiefly in the follow- 

 ing three directions: (i) From Texas eastward through the Gulf 

 States and northward along the Atlantic seaboard to Long Island; 

 (2) from Texas northward through the Mississippi Valley and thence 

 through the Ohio River region into Ohio; (3) from Mexico into the 

 neighboring States and Territories, and from Lower California into 

 Southern California and Nevada." 



This is, I believe, the first Iowa record of the pest and shows that, 

 although it is not common here, the range is gradually being extended 

 through the Mississippi Valley. DAYTON STONER, State University of
