1918] Proceedings of Pittsburgh Meeting 105 



This interpretation of the rule may be questioned and is here pre- 

 sented for the purpose of stimulating discussion. 



(3) A type locality should be cited whenever possible. It can do no 

 harm and may be of material service in establishing the identity of a 

 species. 



The advisability of using a single type in taxonomic work was 

 referred to this Committee at the last meeting with instructions to 

 report. 



(4) The designation of a holotype is recommended whenever practical 

 and it is advised that the specimen be selected with considerable care 

 in an effort to secure a form typical of the species.. 



The holotype should, when possible, be accompanied by a series of 

 specimens showing the range of variation and the entire lot might well 

 be designated as a type series. 



There are small delicate insects where the designation of a holotype 

 is not customary, such as balsam preparations of Aphididae, Coccidse and 

 Itonididae, especially where it is necessary to examine several specimens 

 in order to ascertain structural details. These are certainly type series 

 and should be so designated on the labels, but it is desirable to mark 

 one specimen (as by a ring on the glass) as a type.

Committee. 



The Committee on Entomology in the National Museum 

 made a report, giving a brief summary of progress and sug- 

 gesting the continuation of the committee. 



On motion of Herbert Osborn, the only member of the 

 committee present, the report was referred back to the com- 

 mittee for further consideration. 



The Committee on Resolutions made the following report: 



The Entomological Society of America greatly appreciate the courtesies 

 shown to us by the local Committee of Arrangements, and particularly b}^ our 

 friend, Dr. W. J. Holland, Director of the Carnegie Museum. 



We also appreciate and commend the efforts made to enlarge our membership, 

 resulting in sixty- three additions this year; we should continue this effort, and in 

 these times of stress and hardship, when all our energies are bent upon winning the 

 war, we should look forward more than ever to these annual meetings as times 

 when we get the inspiration to go ahead with renewed zeal, knowing that we are 

 building the foundations of a structure that makes for conservation.
