mark. The Aphides of that region must have a long continuance of the 
egg state; in England this state varies from one month to eight months, 
according to the species, and according to the weather. The length and 
season of the egg state in the Aphides of hot countries has not yet been 
observed, and is an interesting subject for enquiry.—/rancs Walker, in

MONOHAMMUS MARMORATOR, Azrby.—l was so fortunate as to 
recelve a specimen of this rare insect from a friend last summer. It was 
taken in Richmond Square, Montreal, on the 27th of July, 1871. Length 
of body one inch. ‘The markings agree perfectly with Kirby’s description, 
but as the antennae of his specimen were broken off, I will describe. 
those of mine. Antennae a little longer than the body, first joint 
chocolate brown at the base, remainder grey, through which the brown 
appears in spots and streaks ; second joint the same; third joint grey at 
the base, deepening into warm brown at the end; fourth, fifth, sixth, 
seventh and eighth redder brown, grey only showing a little at the base ; 
remaining joints deep red. This is the only specimen I have got. There 
is another in the collection of the Natural History Society of Montreal, 
and Mr. Couper informs me that it was mcluded in his Quebec List. 
Preris Rap.—This destructive butterfly was very abundant about 
Montreal in 1870, and ruined the cabbage gardens around the city. Last 
summer they were not nearly so plentiful, and this coming season I hope 
to see their ranks still thinner, as a good many of the chrysalids that I 
examined this spring contained parasites in the pupa state.—F. B. CauL-
