occasionally; the former insect, forty years ago, was very 

 abundant in this locality. — Joseph S. Baly ; The Butts,

Is L. Bubricollis Double-brooded ? — This question was 

 asked in No. 92 of the 'Entomologist.' In the following 

 number I gave an opinion that it was not double-brooded. I 

 should perhaps have said, regularly double-brooded. Recent 

 experience seems to show that it is not so. I took it this year 

 in our locality freely, throughout June and the greater part of 

 July, but did not observe a single specimen in August. This 

 month (November), while pupa-digging in the same locality, 

 I have taken several pupae of Rubricollis, and also ob- 

 served several half-fed larvee hybernatiug in the crevices of 

 the bark and among the lichens, with which the trees are 

 covered. The larvae are in all stages, from half-fed to those 

 descending the trunks to undergo pupation. Some larvae 

 were in their cocoons, if they may be called so, unchanged. 

 I thought at first that this might be a different method of 

 hybernatiug; but I find they are changing one after another. 

 The pupae may be found on the surface of the ground under- 

 neath leaves, or among the fragments of lichen that have been 

 washed down by the rain, the favourite place being where the 

 earth lies high against the smooth part of the trunk, and not 

 under the arches of the roots. The cocoon is a very flimsy 

 affair, and partakes more of the nature of a web, spun by the 

 united exertions of three or more ; each pupa, however, being 

 separated frou) its neighbour : I have taken up as many as 

 five, hanging in this way together. I expected to have found 

 the pupa spun up behind the lichens, but have not found an 

 instance of it yet. I hope this may throw some light upon the 

 seemingl}' vexed question : " Is Kubricollis double-brooded ? " 

 The various stages from the larva to the pupa, now, will 

 account for the succession of imagos during June and July. 

 This insect seems to be exceedingly local ; it is plentiful 

 about a few particular trees, while others in the same avenue, 

 seemingly as suitable, are entirely neglected. I have taken 

 Rubricollis in some half-dozen woods round Alton, and I 

 know just which trees to go to for them. In these woods I 

 have taken them plentifully in June, and generally during a 

 part of July, but never in August. — [Rev.] A. C. Hervey ;
