Tlicsc iKitcs arc based ii]>(iii an cxamiuatiou of tlic larii'o col- 

 k'Ctioii of bees l)(.'I(mi>in,i>' to Mr. W. M. (JifPard, wbo, as is wcl] 

 known, has been an in(l('fatiiial)lc collector of insects for vears. 

 ])avinu' s])ccial attention in bis collecting;- to the Aculeate IIv- 

 nieno])tcra. Of the <!(> dcsci'ibed species and varielies of native 

 bees, 4!) are rc»])r(>sented in the colbn'tion, most of llieni by fine 

 series. Oahn forms are compk'te. onlv two are missini: ont of 

 the lariic number found an the island of Hawaii, with Maui 

 and Kauai not so well re])resentcd. The ])rincipal result of 

 this examination has been the accnmnlation of data on distribu- 

 tion and variability which ti'iids to weaken the value of certain 

 species in <>ronj)s of closely related forms. Owinii- to the con- 

 tradictory nature of some of the evidence, however, it is con- 

 sidered inadvisable to go further than to point ont certain wcdl 

 marked du])lications. An attempt has also been made, with 

 some snccess, to match u]) forms repvcscnited by but one sex. 

 Xovelties, at this date, were hardly expected, but a few have 

 turned np, notably the nuich-song'ht male of ritf/ulosd. Alto- 

 gether, it is believed considerable is added to our knowledge (»f 

 the bees. Acknowledgment is gratefidly made of hel]) received 

 from Dr. E. C. L. Perkins.
