THE ENTOMOLOGIST. 69 



there has been no account of the method of using it ; and 

 from the communications of some of my correspondents, I 

 am inclined to believe that it is not generally understood by 

 country Entomologists. A brief direction may therefore be 

 of service, and be the means of making many captures during 

 the ensuing summer. The strongest brown sugar, known as 

 " Jamaica foots," is mixed with hot water to the consistence 

 of treacle, or somewhat thinner, and a small portion of rum 

 added and stirred in ; the composition is then laid on the 

 trunks of trees, in favourable situations, with a painter's 

 brush. I have found that it is better to make long and nar- 

 row streaks than broad patches.' " — Extracted from Mr. 

 Greene's admirable ' Insect Hunter''s Companion,^ tvhich I

5. Larvce reimbihing ejected Fluid. — I can confirm the 

 statement of Mr. Peers, in last month's 'Entomologist' (En- 

 tom. 55), that the larvae of lepidopterous insects frequently 

 reimbibe the fluid ejected from the mouth when the insect is 

 alarmed. I have observed this habit not only in the Toitrices, 

 but also in the Bombyces and GeometrtB ; but I think it is 

 confined to cases where the fluid has not been projected, but 

 has remained attached to the head. Many of your readers 

 will have observed with what avidity most larvae, reared in 

 confinement, take in a globule of pure water placed in their 

 way, action of the jaws, as in eating, accompanying the ope- 

 ration : the same action takes place when the ejected fluid is 

 reimbibed, but it is slow and deliberate; why the difference 

 I cannot say ; perhaps the fluid has to be carefully re- 

 stowed ; if so, ai'e we to conclude that it is supplied in such 

 limited quantities that waste has to be avoided ? or is it that, 

 remaining attached to the jaws, the larva has no other means 

 of disposing of it ? I can positively state that the fluid is not 

 always of ihe same colour as the larva ejecting it. That 

 emitted by Endromis versicolor, Notodonta palpina, Nyssia 

 zonaiia and Ciostera anachoreta is in each case dark green; 

 the larvae of the two first-named are green of varying shades, 

 while the two latter have no green about them. — George

6. Cgmatophora ocularis. — I have had the good fortune 

 to take one specimen of Cymatophora ocularis near Cam- 

 bridge. — R. Whyatt ; 16, Newnham, Cambridge, June 29.
