and mining the leaves of the honeysuckle, the larvae of L. emherizapen- 

 nelle and trifasciella may be found to about the middle of the month. 



In rough places such as old disused brick-fields, that have been 

 'die for years, the water plantain (Alisma plantago) will be found grow- 

 ing at the sides of the shallow ponds and pools that are always to be 

 found in this sort of broken ground, the flower stems are at this time 

 quite bare, the whorled branches alone are the only character now to 

 enote what they are, by cutting the stems close to the root and split- 

 ing some of them open we shall probably find the whitish larva of 

 . iidana, which when full grown pupate within the stems, we must 

 ake a good supply of these stems, selecting only those that have small 

 oles here and there in the sides, for it is these only that contain larvae, 

 ie them in a bundle, and keep them out in all weathers during the 

 inter and to near the time of emergence, when they must be put into 

 cage, in due time a fine series is almost sure to be bred. While tak- 

 ng these stems, a search should be made of the common thistles grow- 

 ng so plentifully in these places, for the whitish cases of Col. therinclla 

 ill now be found firmly fixed to the stems, the cases must not be 

 isturbed, the thistle stems must be cut and taken with them. 



On chalky slopes the carline thistle ( Carliiia vulgaris ) will be found 

 rowing pretty commonly in some places, the heads of which must 

 now be examined, for some of them contain the larva of P. carlinella, 

 which will be found at the bottom of the seed head, eating through the 

 seeds, and on the same slopes the vipers bugloss (Echiiim vulgaris J is 

 almost sure to be found ; tlie dead stems must be cut open, when some 

 of them will be found to contain numbers of very small larvae making 

 long galleries up and down the dry flower stems, these would be the 

 larvae of D. ocnerostomella ; a few stems only need be taken, for dozens 

 of moths will emerge from tliem. The larvae of P. lapella is still to be 

 found in the seed heads of Burdock, and in the stems of wild parsnip 

 (Pastinaca sylvestris) the larva of C. dilncidana will be found near the 

 joints; the larva also of C. fraiicillaiia may be taken this month 

 feeding in the stems of the wild carrot, and the larva of A . Lephyvana 

 near the crown of the roots; and in the stems of tall Scotch and other 

 thistles, growing in sandy soils, by the side of ditches, or in waste 

 places, the larva of M. cvibella may easily be found, the heaps of light 

 sawdust looking stuff exuding from holes in the sides of the stems tells 

 us the larvae are at work within.
