4078 Inscets. 



the beach to a height of thirty feet: here some short slopes and broken 

 ground will be met with. Look about carefully, for this is the locality 

 where the elegant Dasypoda hirtipes is to be found. Of this bee I 

 captured some fine examples : the best time to take them is about 9 

 o'clock in the morning, on their first coming out, and before they are 

 laden with pollen, which it is difficult to remove from the plumose 

 scopa of their posterior tibiae. About this spot I also met with Cilissa 

 tricincta and Andrena pilipes. Along the hedge-rows of the fields to 

 the left of the slopes I found the male of Bombus Latreillellus, usually 

 a rather scarce insect : Bombus lapidarius, however, was the most 

 abundant of the genus, in fact occurring in greater profusion than I 

 ever recollect to have observed any one species in a given locality. 

 Apathus rupestris also abounded. 



Having searched the spots alluded to, the best way, I believe, is to 

 follow the path-way on the top of the slopes, carefully examining the 

 foot-path and bank on the left; here, towards the further end, I picked 

 up several specimens of Mutilla ephippium, which is not uncommon, 

 as I captured ten specimens of the female, the other sex I was too late 

 to meet with. In the hard trodden path-way will be found many bur- 

 rowing Hymenoptera, and amongst others Cerceris ornata. 



But I must proceed to enumerate the species in the order in which 

 they are arranged in the Essay, just premising that at the extremity 

 of the slopes you arrive at an open, barren, unpromising-looking piece 

 of waste land, called Southchurch Common, the farther extremity of 

 which is a rabbit-warren ; this is the field of my campaign ! Imme- 

 diately on reaching the end of the slopes commences a raised mound, 

 or wall of sand, which rims parallel with the foot-path to the end of 

 the field which it bounds ; on the south side of this bank most of my 

 captures were made, others upon the flowers and bare spaces on the 

 adjoining common. Tiphia femorata was found here, but I was too 

 late to judge in what abundance it occurs. Of the genus Pompilus I 

 captured the following: — P. plumbeus, niger, rufipes, fuscus, gibbus, 

 pectinipes, sepicola, affinis, and exaltatus. P. rufipes 1 was glad to 

 meet with, it being so very local, and having only once before cap- 

 tured it, in Sandown Bay, Isle of Wight: of this species I took eleven 

 specimens. 



Aporus bicolor: This was the first time I had taken the species. 

 On examining this insect, I was at first led to believe that I had cap- 

 tured a new species, having, as I supposed, met with Aporus at Wey- 

 bridge, and possessing four examples. After a careful investigation 

 of the subject, I arrive at the following conclusions : — All the speci-
