THE ENTOMOLOGIST. 186 



brown plate behind its head. One has just now changed its 

 skin, so I send it you. — Sydney Klein ; The Rock, Reigaie, 

 Surrey, August 27, 1870. 



[It is doubtless the larva of Gortyna flavago. — E. iV.] 



Spider or Mouse. — I have been keeping a large spider in 

 a closed glass case, feeding him on uioths and butterflies, 

 and I find the wings are thrown out in the same manner and 

 condition as they were found and described in the long- 

 continued "spider or mouse" controversy, and thus proving 

 that my opinion, of the spider feeding on both these insects, 

 is correct, and that they may have been the source of the 

 deposit of wings at Filey and other places. — Stephen 

 Clogg. 



The Tea Grub. — Thank you for investigating the tea grub 

 so pertinaciously. I am inclined, however, to take exception to 

 your remark that " it must remain for a time doubtful whether 

 the insect gained access to the tea in China or in London," 

 since the chests are lined with lead, which is hermetically 

 soldered down. The gentleman who brought me the sample 

 of tea has written to me as follows : — " The grubs were found 

 immediately the chests were opened upon arrival. The package 

 consists of a wooden exterior, inside of which is a leaden 

 case, in which the tea is put and soldered down, and at the 

 top of the tea, w^here the lead is soldered there is some paper. 

 When the lead was cut open the grubs were found adhering 

 to the paper and in the tea. Some hundreds of chests were 

 found infested with the grub." — W. Thomson; City of London 

 Club, Old Broad Street, E.G., September 9, 1870. 



Gorrection of an Error: Pachytylus cinerascens a British 

 Insect. — The locust that was forwarded last year from Aber- 

 deenshire was erroneously stated by me to be P. migratorius : 

 it is P. cinerascens, and is the only British specimen that 

 I have seen of that species, which is the Locusta Christii of 

 Curtis, ' British Entomology,' xiii. 608. — Francis Walker. 



[Mr. Curtis's specimen has left the country with the rest of 

 his collection, and is now in Australia. It is the first recorded 

 British example of the species : the Aberdeen specimen is 

 the second. — E. Newman.^ 



The Wheat Midge. — The accompanying envelope con- 

 tains portions of three ears of wheat, eaten by a small 

 caterpillar, of which you will perceive many. They seem to
