From the abo\"c figures we see that the ciione cells surpass slightly the worker 

 cells of mcllifica in tlimeasions. 



Queen cells resemble in form those in lucUifica; in one case I measured 'it 

 is 18.7 mm in depth and is 9.8 mm in the maximum inside diameter. 



It is well known in this counti}" that wax dealers a()prccialc the Japanese 

 beeswax owing to its superior qualitj'. The chemical and physical properties 

 are seen in the study by Shibasaki (1900). 



3. On the Peculiar Pore of the Drone Cocoon. 



As the characteristic of the drone cocoon comes next in consideration a 

 fine circular pore which I have made out at the ele\'ated out tip of it ; it comes 

 into \iew, when the nurse bees take off ; he \\ax_\- cap sealing each cell which 

 co\-ers the cocoon (Fig. 9). This pore is not detected in iiieUifica at all (Fig. 

 12), but in our bees it rudiment is alread)- obvious in the cocoon just formed; 

 it is inconspicuous at fir.st, but is recognized at ease by artificial exposition of the 

 tip of the cocoon. 



The N'oung drones cotr.c out, cutting round the outer cocoon wall circularly, 

 so that it falls in circular disc (Fig. 10, li). Seen on median transxerse section 

 through its jjore (Fig. I 3), the disc consists of about IO la\x-rs of silky substance 

 \\hich are diminishetl in number towards the peripher}-, so as to decrease the 

 disc in thickness, until its .sharp edge is brought about. A dark brown sub.stance 

 of unknown matter is deposited along the inner surface of the layered .structure 

 ju.st described: it is thicker near the passage of the pore and is thinned out to- 

 wards the periphery, p(;netrating probabl}- between Ihe layers of the disc. 



The pore is nothing other than the outer o[5ening of the passage communicat- 

 ing the interior of the cocoon with exterior. The passage is a straight canal, 

 but becomes con.stricted at the neck \\hich is surrounded by the dark brown 

 body, so as to be transformed into the funnel-sha])ed jja.ssagc which is 0.4 mm 

 in length, 0.4 to O.G mm in diameter at outer and 0.25 min at the inner opening. 



Instead of thin and loose .structure of the cocoon v\'all in incllifica, it is of a 

 considerable thickness in our bees : the reason why the pore of the cocoon is 

 confined to the latter consists, as I dare to ask^ume, in this thickness of cocoon
