The Hoiiioptcra have several working on thcni : Messrs. 

 Giffard, Muir, Timberlake, Swezey, Bridwell and Crawford. 



The lleteropteya are not being actively dealt with jnst at 

 present, nor are the other Orders: Orflwptera, Odonata, Neu- 

 roptera, etc., thongh nuich material is at hand for working, 

 especially in the Heteroptera. 



In fact the entomologists of ITonolnln, members of the 

 Hawaiian Entomological Society, or those engaged officially in 

 entomological work of one kind or another chiefly with refer- 

 ence to economic or practical work with insect pests at one or 

 another of the different institntions, are interested in many of 

 tlie lines of research above indicated, and have spent mnch 

 time on some of them, and are continuing to do so as time 

 and opportunity presents. Bnt in this way progress mnst 

 needs be slow as compared with a research worker ])ntting his 

 whole time and attention on a special subject, without other 

 duties to continually interrupt or interfere with his progress. 



2. CoI]ecfi)ig. 



For most of the lines above mentioned, much collecting is 

 necesssary, not only in general throughout the Islands, l)ut in 

 special places where no collecting has been done, particularly 

 in localities where the native forests are rapidly <in the de- 

 cline and are disappearing, and this can best l)e done by 

 persons trained in the special methods of insect collecting in 

 these Islands, to obtain results, and capable of taking the de- 

 sired notes and data as to host, hx-ation, other conditions, etc. 



3. Systematic Entomology. 

 This line of work must go hand in hand with biological 

 researches. It involves : descriptions of new s])e(ues ; revisions 

 of groups; production of synoptic tables, etc. Many of the 

 members of the Entomological Society are having a share in 

 this already. 



4. Bearing on Factors of Evolution. 

 Many of the biological problems are of great importance on
