extreme margin of the clypeus, the labrum, palpi, and the point 
of the collar. With the exception of the first, all the segments 
of the abdomen are red at the sides and on the ventral surface, 
this colour increasing in extent towards the apex. The legs are 
brownish yellow, the coxe and apophyses being black; the four 
anterior femora are black at the bases ; the two posterior legs, the 
bases of the femora, and the apex of the tibie are fuscous, and the 
margins of the tarsal joints brown. ‘The wings have the anterior 
margin transparent white, not yellow as in the other sex, and ~ 
the margins of the stigma brown; the nervures are brown or 
bright yellow. Lophyrus virens has been observed in this | 
country (the Netherlands) by M. Six near Utrecht, by M. Brants 
near Borculo, and by the writer near Breda, and, if I remember 
rightly, near Brummen also. This species is very scarce with us, 
and seems to be so in other countries likewise, so that it cannot 
be considered as one of the insects injurious to the pine.

NOTES ON CERTAIN SILK-PRODUCING BOMBYCES.

SILK-PRODUCING BoMBYCES WITH OPEN Cocoons. 
Or these, four species will be mentioned, which have been 
bred in England, France, and Germany. 
Attacus Cynthia; Attacus Promethea; Attacus Cecropia; 
Attacus Atlas.—These four species in America go under the 
generic name of Samia. Cecropia and Promethea also go under 
the generic name of Hyalophora in America. The larve of these 
four species all have the same form and appearance, and the 
imagines the same designs on the wings. The moths can all be 
taken with the hand and will readily hold to anything—while 
those of the three species first mentioned, especially Yama-Mai 
cannot be held in the hand; the least touch causes them to drop 
heavily down, and make half a dozen somersaults before they 
keep quiet. Pernyi, however, is not so wild as Yama-Mai. 
Attacus Mylitta (from India), also has the same habits as 
Yama-Mai. Selene (from India).—-Although belonging to another
