118 MISS STAVELEY ON THE FORM OF THE [Mar. 25, 
6. Nores on THE Form oF THE Coms (PECTEN) IN DIFFERENT 
ANDRENID& AND APID&, AND ON THE ALAR HOOKS OF THE 
Sprecies or SpHecopEes AND Hatnicrus. By Miss E. F. 
STAVELEY *. 
T have made a few notes in the hope of saving your time and eyes; 
but I fear they are of very little value; and, as you are aware, I know 
so little of what has been already written on the subject, that my 
notes, even if correct, may not be new. JBesides this, my examina- 
tion of the parts of the mouth has as yet been confined to about 
twenty-six Bees of various species and the three sexes. 
There are some peculiarities in the maxillee of the Bees which I 
think might serve as generic or specific characters, and which I 
believe have not yet been used for that purpose. 
One is the presence of a row of strong, flat hairs or teeth, forming 
a sort of comb, varying much in form and situation. 
In all the Andrenide where I have found it, it forms a wavy line, 
commencing near the base of the upper joint of the maxilla about 
midway between the two margins, as in Andrena cingulata, 2 
(figs:.1,.2). 
* Communicated by Dr. J. E. Gray with the following letter :— 
“I beg of you to lay the following observations, which Miss Staveley has 
sent to me, before the Society. They indicate some characters which appear to 
have hitherto been overlooked.
