hot and calm, without which the insect does not fly ; when the weather is favourahle, 

 I take in half an hour four or five specimens of Bolbocerus mohilicornis, but more 

 females than males. I have remarked that those taken at the end of May are the yel- 

 low and brown varieties, which are only insects incompletely developed, those which I 

 have taken in June and July are all black on the upper surface. 



" I do not know any method of capturing the Bolbocerus in the day-time ; there 

 ought to be one, for the insect is then in the ground, as I have observed that living in- 

 sects which I had brought home, and which remained all day buried in the earth at 

 the bottom of a pot containing about four inches of it, every night came out, but in 

 the morning I found they had gone in again ; each day making fresh holes. JVf . le 

 Major d'Aumont has told me he has often taken Bolbocerus mobilicornis near Lyon, 

 on the banks of the Rhone, by digging into the holes made by these insects ; he has 

 also taken Bolbocerus Gallicus, near Marseilles, in the same manner. For my part, 

 I have not noticed the holes of Bolbocerus mobilicornis in the locality where I take 

 the insect, probably because the soil is not sufficiently damp and clayey to preserve 

 their form ; I have not observed any such holes as those made by them in captivity, 

 but I think that with a little patience I might discover them." 



Mr. Curtis remarked that many years ago he saw a number of these beetles flying 

 at dusk over a heath near Norwich. 



Mr. Stevens said he once caught one flying in a room at the Bull Inn, Birch Wood, 

 attracted, he thought, by a light burning therein.

New Species of Saccophora, fyc. 



" Description of a New Species of Saccophora, found in the valley of the Amazon 

 by Mr. Bates, and proposed to be named in honour of him, Saccophora Batesii." 

 By Edward Newman, Esq., F.L.S., &c, President. This paper contained a re- 

 ference to the only other known species of the genus described by Dr. Harris, under 

 the name of Melsheimeri, and critical observations on both species, the larvae of which, 

 in their sack-like coverings and general habit, so much resemble the Psychidae, while 

 in their perfect state they appear to belong to the true Bombycidae. 



Mr. Westwood thought that these insects well showed that because the larvae of 

 different species resembled each other in form and habit, the perfect insects were not 

 necessarily of the same genus or family ; for here was an insect whose larva was a 

 case-bearer, like the Psychidae, and yet the imago, especially the female, and this sex 

 wai always more normal than the male, was winged in both sexes, and was allied to 

 Odonestis ; and further, he considered that M. Bruand and other French entomolo- 

 gists were in error, in associating Talaeporia and such case-bearing Tineae with 

 the Psychidae.
