On the third and first legs group 7 occurs three out of nine 

 times and on the second legs four out of nine times. In number 

 of pores it varies from 6 to 16, with about 12 as an average. 



Groups 8 and 9 are either totally absent or when present they 

 consist of only a few pores which are widely scattered. When 

 present the pores of the two groups combined vary from 2 to 19, 



Groups 10 and 11 are both always present on the third legs, 

 their number of pores varying from 9 to 19. On the second 

 leg one of these groups is absent in four instances and their 

 pores vary in number from 1 to 13. On the first legs one group 

 is missing twice, their pores here vlarying from 5 to 13. 



Groups 12 to 15 are more scattered than in the workers, and 

 the pories are fewer in number. Only occasionally are groups 

 12 and 13 more or less definite, while in the workers they are 

 quite definite. The total number of pores for all four groups 

 varies from 2 to 41. 



On the third leg either group 16 or 17 is always absent, and 

 in one case both groups are missing. Their total number of 

 pores varies from to 9. On the second leg both groups are 

 usually present, with their pores varying in number from 4 to 

 20. On the first leg one and occasionally both groups are ab- 

 sent, their number of pores varying from to 12. 



Group 18 was never discernible in the queens. 



Among the nine sets of legs of queens examined the pores for 

 the outer side vary in number from 90 to 150 and for the inner 

 side from 55 to 117, giving a variation in number from 172 to 

 262, with an average of 225 pores for both sides of three legs. 



Stings of queens. An examination of the pores on both sides 

 of nine queen stings showed that their disposition is similar to 

 that of the worker stings. The combined number of pores for 

 both sides of these stings varies from 83 to 111, with 100 as an 

 average. 



From a count of the pores on the four wings, six legs, and 

 sting an average queen, therefore, is found to possess 1860 of 

 these organs. 



Wings of drones. On the wings of drones group 1 varies in 

 number from 310 to 325, with 316 as an average; group 2, from
