THE ENTOMOLOGIST. 39 



Beetle damaging Silk Ribbon. — Mr. A Shavland, of 39, 

 Bishopsgate Street Within, has shown me some ribbon per- 

 forated through and through with small circular holes, 

 resembling shot-holes. He also brought the roller on which 

 the ribbon had been wound, together with the beetle in its 

 various stages. It proves to be Anobium striatum : it had 

 evidently been feeding on the wood when in the larva state, 

 leaving a number of longitudinal galleries, as in the previously- 

 mentioned case of the Callidiuui and the lead. Its injurious 

 effect on the silk arose solely from the instinctive desire to 

 escape when mature. No remedy can be applied, because 

 the insect cannot be discovered until the mischief is com- 

 pleted ; but more care should be exercised in the choice of 

 wood for these rollers, for if perfectly sound wood is 

 employed in the manufacture, the insect is not very 

 likely to introduce itself afterwards. By burning those that 

 are infected, you may prevent, in some measure, the increase 

 of the injury. 



Doritis Apollo at Epping. — I see, at the end of your 

 volume on the butterflies, that you have not seen au 

 authenticated specimen of Doritis Apollo caught in this 

 country. You will be pleased to learn that I have one in my 

 possession, which was taken by my late son at Epping, about 

 the year 1847 or 1848, at the time he was a pupil at Dr. 

 Usmar's school, which was previously that of Isaac Payne, 

 where I was also a scholar for six years, and part of the lime 

 with Henry and Edward Doubleday. It is possible Henry 

 Doubleday may have attempted to stock the neighbourhood 

 with some of the rarer butterflies and moths. I think I 

 have heard my son say so, but am not quite certain. — Geo. 

 Bax Hohnes ; Alton, February 6, 1872. 



On receipt of this letter I immediately forwarded it to my 

 friend Henry Doubleday, who thinks there must be a mistake 

 in the supposition that the specimen was taken at Epping. I 

 have already expressed my opinion, as alluded to by my 

 correspondent, that there is no authenticated British speci- 

 men of Apollo. 



The Processionist Caterpillar. — I shall feel much obliged 

 if you can give me a little information about a caterpillar 

 very common here. 1 have now a nest of these in my room 

 here, and which I am watching with very great interest. The
