The work of my department was delayed by my voyage to 

 Europe from the month of May till October. Nevertheless, I 

 am very happy to state that the portion of the collection stored 

 in the new pattern of boxes has passed through those most dan- 

 gerous months for an entomological collection without injury. 

 After a general revision by myself in the first days of May, Mr. 

 P. B. Mann had the kindness to examine the whole collection 

 twice in my absence. After my return, in a general revision, 

 the collection was found to be in a perfectly good condition. 

 The same may be said of the alcoholic collection. It is true, 

 and worth repeating, that the more expensive way of putting up 

 entomological collections, viz., in good and costly cases or 

 boxes, is in the end the safest and cheapest mode, saving time 

 as well as specimens. Even some old collections of exotic in- 

 sects, formerly much infested, are now nearly safe, through 

 reiterated care and observation. Of course a certain time must 

 always elapse before new additions can be entered in the collec- 

 tion. For examination they are placed in provisional boxes, 

 and are watched for about three months, before being finally 

 arranged in the collection. If they are still found to be in any 

 ■way infested or in doubtful condition, this care is continued 

 for a still longer time. 



Concerning the work in the arrangement of the Articulates, 

 the beautiful and very important donation of Baron d'Osten-
