NOTES ON THE CAPTURE OF RARE SPECIES IN 1858. 117 



the rounded form on the female side, with two patches of 

 white pubescence above, the male side being much less 

 rounded, or lanceolate ; this would belong to the division of 

 perfect hermaphrodites, according to Burmeister, that is, the 

 external form is perfect male on one side and female on the 

 other. 



The above is the fourth instance which has come to my 

 knowledge of hermaphroditism in the Aculeate Hymenoptera ; 

 the first being the remarkable example figured in my Mo- 

 nograph of the British Bees, and also in the third volume of 

 the Zoologist ; Mr. Walcott has also an hermaphrodite of the 

 same bee, Anthophora acervorum. The third specimen is 

 of a species of Nomada, N. Baccata, and the fourth the 

 Andrena figured on the frontispiece of this volume (Fig. 7). 



As the foregoing list will probably induce others to visit 

 Lowestoft, the pleasure of their capture will be much en- 

 hanced by the knowledge that they are exploring ground 

 which the greatest English Hymenopterist traversed in the 

 year 1806. In the life of the Rev. William Kirby it is re- 

 lated, in a letter to Mr. Spence, " between walking and 

 riding I managed to get as far as Lowestoft, from whence at 

 the end of the first week I started." I felt assured from this 

 that the very ground I was hunting over had been previously 

 visited by Kirby, and this conviction, I need scarcely add, 

 not only rendered the spot doubly interesting, but imparted 

 an additional pleasure to my successful investigations. 



Note. — The captures at Lowestoft and in its neighbourhood 

 were made during the two last weeks of July and 

 the two first of August.
