THE ENTOMOLOGIST. 245 



with the brisk flight of Philanthiformis : both these species 

 seemed partial to the neighbourhood of the cliffs : I never 

 saw them fly except in bright sunshine, and tbey seemed 

 most common in the forenoon. Mr. Curaming found a full- 

 grown larva of Deilephila lineata feeding on dock, but it 

 unfortunately perished in the act of turning to the pupa. We 

 also took Stellatarum (abundant), Complana, Complanula, 

 B. Trifolii (larva), Apiciaria, Pullata, Cytisaria, Vernaria, 

 Immutaria, Alchemillata, Linariata, Galiata. We did not 

 sugar, but the following Noctuae came to light — Glandifera, 

 Alsines, Lunigera and Serena; and Mr. Gumming took one 

 specimen of Absinthii the day we left. Purpuralis, Cespitalis, 

 Cingulalis and Punctalis were all abundant. Also Cerussellus 

 (abundant), Inquinatellus, Perlellus, Sinuella and Nimbella 

 (common). Marmorella (a few), Microdactylus, Tetradactylus 

 (abundant), Phseodactylus (abundant in one cove by the sea). 

 Considering the short time we spent at the Lizard, and that 

 collecting was not our principal object, I think this list shows 

 that the locality is well worth working. — TV. C. Marshall. 



Mr. FetherstonliaugK s Crotchets^ and Mr. Newma7i's 

 replies the7'eto, — As to Crotchet No. 1, I quite agree with 

 Mr. Newman. It seems to me impossible to devise a 

 cheaper, simpler, or more effectual method of killing an 

 insect than the stupifyiug it, in the first instance, with laurel- 

 leaves, and afterwards piercing it with a quill or steel pen 

 dipped in a saturated solution of oxalic acid. Herfe, unhap- 

 pily, our agreement ends. Mr. F. objects to camphor, as 

 having a disagreeable odour : " De gustibus," &c. To me 

 the odour of camphor is delightful, and, at any rate, preferable 

 to that detestable preparation called benzole. But Mr. N. 

 objects to its use on very different grounds. " Camphor and 

 grease," he remarks, "are inseparable — cause and effect; 

 you cannot use camphor without having grease." J am not 

 prepared to deny this ; but ] wish to ask Mr. N. whether he 

 insists upon the converse of this proposition, i. e. that if 

 there be no camphor there will be no grease ? Scarcely, I 

 think. He states that Mr. Doubleday uses a weak solution 

 of bichloride of mercury dissolved in alcohol to the underside 

 of the insect, and that this process effectually prevents grease, 

 mites, or mould. 1 must demur strongly to this assertion, so 

 far as grease is concerned. Take, for example, the genus
