114 THE ENTOMOLOGIST. 



covered with seed these cocoons are not very obvious in the 

 sample, but if submitted to a fine sieve the loose seed will 

 readily pass through, and the cocoons with their destructive 

 tenants will remain in the sieve. They can then be thrown 

 into a basin of" boiling water, and thus quickly destroyed. 

 I hope my correspondent will endeavour to rear some of the 

 perfect moths, and address them to a competent entomologist 

 to obtain the scientific name. I shall have much pleasure in 

 doing this if he knows no one more competent. If a sample 

 of the seed be kept in a gallipot and covered with a piece of 

 glass the moth will be sure soon to emerge, and will be seen 

 resting on the under surface of the glass. The larvae are not 

 likely to prove destructive to wood ; but confine themselves 

 to the seed-diet which they have spontaneously selected. —

IV. N. Nicholson d Son. — Julus sahulosus. — The enclosed 

 worms have been sent to us by a client in the west of Ireland 

 to ask if we can identify them, and suggest any remedy for 

 the ravages they are committing on sandy soils. Mr. Hadfield, 

 of this town, has recommended us to send them to you, as 

 being the most skilled naturalist that he knows in England; 

 and we should esteem it a great favour if you could furnish 

 us with the desired information. 



[The creatures you enclose are Julus sabulosus, of various 

 sizes and ages. They are very abundant in sandy soils, 

 feeding on any vegetable substance they can meet with. It 

 would be particularly interesting if you had described the 

 nature of the ravages they are committing; what plants are 

 attacked ; and how they are attacked. I'he species of Julus 

 seem to be generally vegetable-feeders ; they frequent fruit- 

 trees on walls, entering the fruit by little holes that wasps 

 have bitten in the skin, and excavating the interior, in which 

 they coil up, always lying on one side. There is a good 

 paper on them in the eleventh volume of the Transactions of 

 the Linnean Society, in which all the species inhabiting this 

 country are described. As to a remedy for this, or any similar 

 insect-plague, there is none; on the contrary, great injury is 

 done to our gardens by placing confidence in chemists' 

 nostrums. — Edward Newman.']
