and linden, on the underside of leaning lindens and in open- 

 ings of hollow trees. 



The first unijuga was taken on September 5th. Quite all 

 the species mentioned in this article were abundant from the 

 I3th to the 1 5th of September. The supposed hermia was 

 taken on the i6th of September and at the same time the woods 

 were full of amatrix. The supposed pura were taken not 

 later than August 2d. The last parta was seen on the 3d of 

 October. 



The egg of Catocala cerogama is small, almost black and 

 smooth looking to the eye. Depressed spherical. Meridian 

 plications small, low, smooth looking. But little flattened on 

 the attachment surface. No well-outlined polar zone, a mere 

 smooth surface without plications. The lateral plications or 

 ridges bifurcate about the equatorial region, but there is no 

 distinct zone there. In the sunlight the color seems to be a 

 dark reddish black. The dark smooth look is the chief char- 

 acteristic. 



The egg of Catocala relicta of medium size, dark green, 

 with a dark brown narrow equatorial zone. It is a slightly 

 flattened sphere. There are about eighteen meridian striations 

 that fork just above the equatorial zone. Polar region with- 

 our plications and with two slightly ridge-like concentric cir- 

 cumferences. Very fine cross lines or parallels. Slightly flat- 

 tened at attached pole. The egg of Catocala concumbens is of 

 medium size, dark lead color. Eighteen strong meridian plica- 

 tions that bifurcate at the equatorial zone and with further im- 

 planted plications, giving many more than in the eggs 

 of relicta. Depressed spherical. A little concave on 

 attached side. Plications toward the pole strong and with deep 

 depressions between. Free polar zone without ridge-like par- 

 allels or rims. The chief characteristics are the numerous pli- 

 cations in the equatorial zone. 



The egg of cara is small, dark brown, with almost white 

 hemispherical, faintly red-brown. Eighteen to twenty-two 

 rather strong meridian striations, bifurcating at the narrow 

 equatorial zone. The free polar region is a depression about a 

 slight polar elevation. Flat on the attached surface.
