certain flowers over others, but very brilliantly coloured flowers are less 
attractive than those of more subdued colours. The results of a long 
series of experiments are summed up with the conclusion that blue or 
violet are the most attractive colours, and bright yellow the least so.

The writer asserts that the structure of the genital organs is too little 
known, and too variable a character to be taken into consideration, and 
disputes Morawitz’s revision of the Bombi, as being chiefly based upon 
it ; the species being discussed in detail. A table of the females and 
workers is appended.

After a brief introduction, the author describes the five different 
systems of so-called salivary glands, one of which is found in the so- 
called tongue, three in the head, and one in the thorax. These glands 
differ very much, both in different species and in the sexes of bees, and 
evidently perform very various functions. System iii. is formed within 
the substance of the first part of the spinning glands of the larva ; 
systems ii. and v. are formed from the excretory channels of system iii. 
Systems i. and iv. are entirely new formations, produced by invagination 
of the epidermis. The organ of smell has not yet been positively iden- 
tified, but evidently resides in the antennae, the appendages and structure 
of which are minutely described.
