CONCLUDING REMARKS. 



A scope 111" the external features hr<)(iL;lit forth in the foregoing,' descriptions, 

 amont;' wliich the hrowii culor of llie mouth-parts, the distinct bandintj on the 

 dorsal plates of the ahdoiiit-n, the ])ale \-ellowish colorin;^ of its ventral surface, 

 the iieeuliai- ni;uKin!_;s and ihe tibial jiroje'ction of the drone leys as well as 

 the criterion of tile winy-vcnatioii are to bo enumerated, are so characteriostic 

 to the- Japanese bci- that it can not be classified with, but is put against A- 

 iiiLlliJua. A new fact that the tonK;nt bands which are m:idc out in tiie 

 present in\estii,r,Uion to be exlended into the 6'.h ab-domin.'l sei/n;ent, enforces 

 finthernuire us ti) assume this \ie\v. 



What is the anatomical details concerneil, there arc a series of new facts 

 of prime importance which ha\e been added b\' the present investij^ation ; in 

 particular the)' are made out in the male copulatory organ. Striking is the 

 conslrictioii which marks off the pro.ximal [)ortion of the penis from its distal 

 part. The sini])lc thickenings of the penis wall is seen in.stead of the hard 

 chitinous plates of the dorsal wall in .-/. mcllificn ; not unfrequently they are 

 e\'en neaily lost. The conspicuous structure is seen, in the pneumoph\'ses 

 Avhich are not only leprcsented by the principal horns prolonged, but consists 

 also of the 3 well tleveloped accessor^' conical tubes of unequal length. The 

 deep groo\'es separating the cross-ridges from one another as well as the 

 characteristic spining on them antl on the \'entra! quadrangular region stand back 

 b>' no means to the new facts just montioned. The palinated structure of 

 the so-calleil doubl\' pirinate-lobed projection with the well- developed dorsal 

 triangular region must be added to tliese important facts. 



In the biological habitude of life there is a series of sharp contrast in 

 ■v\]iich the Japanese bees stand to A. »lellifica. First of all our bees are so 

 coward and helpless that they arc defeated, without intending a defence, by 

 formidable offence turned by A. luellifica upon. The latter are in their turn 

 offentled and damiged by dreadful attack of wild wasps which are, however, 

 p.iwerless on the Ja])anese bees, because at the offence these shy creatures
