else the caterpillar is very liable to be crushed. The mode of ascertaining whether 

 anything be in the grass, is by noticing whether the centre leaf be discoloured, not 

 mined. Of course, if the larva has just taken possession of its new home, the dis- 

 colouration may not be discernible, and it is therefore necessary to examine all the 

 plants. If, on opening any of them, there should be a pale buff larva, slightly 

 attenuated at each end, and with a minute spot on the anterior edge of each segment 

 just above the spiracles, you have the object of your search. It grows to about half- 

 an-inch in length, and changes about the middle of May : the perfect insect coming 

 forth in the beginning of July. The chrysalis is pale brown, enclosed in a snow-white 

 cocoon. — John Scott; Ferry Road, Renfrew, February 28, 1854. 



Note on Colletes Daviesana. — When in Cumberland last July, I found some 

 cocoons protruding from a bank, and quite exposed to the vicissitudes of the weather, 

 from the sandy soil having been excavated beneath. These I brought home with me, 

 and in August following, bred from them three females and one male of Colletes 

 Daviesana, Kirby. A host of small parasitical Hymenoptera made their appearance 

 a few days earlier than the Colletes, but I am quite ignorant of their generic or spe- 

 cific uames. The cocoons were brownish, rather thick, of a firm texture, and enclosed, 

 end to end, in an outer envelope, of a dirty white colour, somewhat resembling fine 

 tissue paper. — Thomas John Bold; Angas Court, Bigg Market, Newcastle-on-Tyne,

Capture of Andrena analis in Cumberland and Northumberland. — I found a 

 colony of Andrena analis, Panz., in a sandy hedge-row, partially covered by heath, 

 near Naworth Castle, Cumberland, and another in a similar locality, a little below 

 Featherstone Castle, Northumberland, in July last. The females were most abundant, 

 and were captured as they entered their burrows, whilst the males were enjoying 

 themselves on the flowers of Hieracium near by. The first colony had a western, and 

 the last an eastern exposure. I took a few specimens of Nomada flavoguttata, enter- 

 ing the burrows of the Andrena ; perhaps it is parasitical upon the species. — Id. 



Capture of Andrena coitana (Kirby), in Cumberland. — This species, like A. analis, 

 is a dweller in upland regions, where it is found in warm sheltered nooks near the 

 water ; A. analis, on the contrary, preferring high unsheltered situations. The males 

 begin to appear towards the end of June, and the females a week or two later. I found 

 both sexes on the banks of the river Irthing, a little below the Wall-holme. The 

 females frequent the flowers of Hieracium and brambles, preferring the latter ; the 

 males are sometimes found with their partners, but are to be taken in most abundance 

 by examining the flowers of Campanula? towards evening, and early in the morning, 

 where they will be found asleep, coiled about the pistil. Although the sexes were in 

 plenty, I was unable to trace them to their nidi, which I fancy are not far from the 

 water; for although I sometimes got males upon the hill-sides, yet T never found 

 females but in the hollows. One female has a Stylops protruding from its abdomen. 

 — Id. 



Capture of Andrena <estiva (Smith), in Cumberland. — I took in July about half- 

 a-dozen males in the same locality as A. coitana ; they frequented the same flowers, 

 and, like the male of that species, often sleep in the smaller Campanulas. The speci- 

 mens were in such good order, that I think the females had not appeared. This spe- 

 cies, like A. analis, emits a very pungent odour, resembling garlic, when laid hold of.
