34 ENTOMOLOGICAL NEWS. [July, 'o8 



MR. PHILIP LAURENT is working as hard as usual. He always was an 

 ardent collector. Now that he has retired from business he has 

 more time to devote to entomology. 



SLEEPING HABIT OF A BEE. Some years ago I published a short 

 article on the sleeping habits of some Hymenoptera, and since then 

 have made various observations on the same and other species. A 

 few years ago I found a little black bee sleeping on the daisies near 

 my place; at the time I could not get it named, but recently through 

 the kindness of Prof. Cockerell I learn that it is Panurginus illinoi- 

 ensis Robt. Only males have been found asleep ; they rest with the 

 wings folded close to the body upon the yellow centre of the daisy. 

 The first are found asleep about 6.30 P. M., and by 7 o'clock there are 

 plenty of them. I notice the first specimens in the last few days of 

 May, and they are found up to the middle of June. So soundly are 

 they asleep, even before 7 o'clock, that one can frequently pick the 

 flower and carry it about without disturbing the tired little slum- 

 berer. NATHAN BANKS.

SAMIA RUBRA. In the May number of the ENT. NEWS for 1907, 

 page 214, I published a query as to the probability of the food plant 

 influencing the color of this species and asked for help in the investi- 

 gation. I was not successful in breeding this moth during 1907, and 

 no one else has yet sent me any data respecting it. 



There is undoubtedly a local race of this species to be found in 

 the interior of British Columbia, the general color of which is purple- 

 brown above on all wings, whilst the underside is always grayish. 



Specimens from Los Angeles show ground color of a burnt sienna 

 brown, which is reproduced in a darker shade on the underside. The 

 markings of both forms are very variable, the only difference being
