CiLstodian.] 18 [May G, 



Messrs. E. Bicknell, N. H. Bishop, W. T. Brigham and P. 

 R. Hunt, have made small donations during the year. 



The meetings of the Section of Entomology have been 

 remarkably sustained, often proving as full of interest as the 

 general meetings of the Society; almost every month several 

 papers have been read. By the construction of a working- 

 room, the insect cabinets, formerly scattered through various 

 parts of the building, have been brought together ; during 

 their storage in inaccessible places, some injury resulted from 

 the ravages of Anthreni, and, although these pests have 

 been carefully eradicated, only constant vigilance, which the 

 centralization of the collection will now permit, can ensure 

 its safety. Over forty trays have been arranged and placed 

 on exhibition. The collection of Guatemalan insects, pur- 

 chased of Dr. Van Patten, is very rich in duplicates, and 

 enables us not only to effect exchanges with museums 

 and individuals, but affords an opportunity, seldom enjoyed, 

 of studying the variation of tropical species. With the 

 assistance proffered by Mr. P. S. Sprague, about one thou- 

 sand Coleojjtera have been selected from this collection, set 

 and arranged, while Mr. Sanborn has spread and displayed 

 half as many Guatemalan Lej^idoptera. The following per- 

 sons have }>resented specunens to the department : Miss Lucy 

 Brewer, Rev. I. F. Holton, Drs. G. H. Brown, S. Knee- 

 land, I. T. Talbot, and C. E. Ware, Capt. Lewis, Messrs. E. 

 N. Abbott, F. W. Brewer, W. S. Brewer, W. T. Brigham, 

 J. W. Brooks, E. Burgess, E. C. Cabot, R. C. Greenleaf, C. 

 Q. Hill, S. Hubbard, D. M. King, A. A. Kingman, T. Lyman, 

 J. C. Merrill, Jr., A. Reynolds, S. H. Scudder and L. Weth- 

 erell. 



The Lower Articulates remain in the condition reported 

 a year ago ; a few purchases have been made, and donations 

 received from Drs. G. H. Brown, and J. B. S. Jackson, and 

 Messrs. N. H. Bislion and W. T. Brigham.
