I was, of course, delighted at the sight ; but it is exceptional and in- 

 dicates a noteworthy reform. It is not to be supposed that every 

 institution can follow it. because it means practically the entire 

 time of at least one man. 



I do not suggest that it is practicable to put all the collections in 

 order everywhere; the thing is manifestly out of the question. I 

 venture to propose, instead, two things : 



(1) That all types and cotypes of groups not yet perfectly ar- 

 ranged shall be kejDt apart themselves in perfect order, pending the 

 classification of the whole series to which they belong. In this way 

 it would be possible to examine them, both for purposes of study and 

 to see that they were not being injured. 



(2) That all institutions receiving types and cotypes should pub- 

 lish annually lists of them, so that students might know what was 

 available. These lists should include types based upon specimens 

 already in the collection. Such lists would be far more valuable for 

 practical purposes than the usual accession catalogues of museums, 

 which remind one of the inventory of some old-fashioned curiosity 

 shop. They would also amount to the public acknowledgment of the 

 types received, with the accompanying recognition of responsibility. 

 As a model of such a list as I propose, I can not do better than refer 

 to the list of type fossils now being issued by the United States Na- 

 tional Museum. 



Those who describe new insects often have long series of cotypes 

 which they would gladly distribute for the benefit of students if they 

 could feel more certain that they would be properly cared for and 

 made readily accessible.

NOTES UPON A LITTLE-KNOWN INSECT ENEMY OF COTTON 



AND CORN/' 



By Wilmox Newell, Shreveport, La. 



The cotton crop probably numbers among its insect enemies as many 

 different species as any other crop of equal importance, and the litera- 

 ture treating of cotton insects has now become voluminous. With the 

 study and attention that has been given cotton insects during the past 

 few years one would not expect to encounter a species, seriously 

 injurious to the cotton plant, concerning the habits of which little 

 or nothing has been written.

 April [141. 1906. At the time Mr. Newell's paper was presented this insect was 

 considered as a variety of Cicada nigriventris Walker. — Ed.
