14 ENTOMOLOGICAL NEWS. [Jan., 'OO,. 



Tubercles light at end but dark at base. The two tubercles 

 on top of the 8th abdominal segment raised into a slight ridge. 

 The hump over the 5th abdominal segment is gray instead of 

 yellow, as in cara. The lateral row of setae of short but dis- 

 tinct bristles. A yellowish shade covers most of the ventral 

 surface. The ventral spots are intensely black. On the side 

 of the 6th abdominal segment, the lateral dark band of lunules 

 is darkest. Head very small. The full grown larva is unusu- 

 ally broad or flat. The spiracles are almost black. The body 

 bristles are few and very short. In the small, flat head, with 

 its upper short, horn-like projections, the elliptical cross, hump 

 over the 8th and Qth abdominal segments, parta, cara and 

 amatri.v agree, barring the color. The larva found on willow 

 began spinning its cocoon on the 21 st of July and pupated on 

 the 26th. The chrysalis gave an imago of C. amatri.v rar. 

 nurus'on the I5th of August, lacking one day of having been 

 a chrysalis, three weeks. 



The imago from the larva taken on the 2/th of July was a 

 fine, large nurus and emerged on the 25th of August. 



Catocala concumbciis is not unusual in the middle part of 

 summer at Vinton, but its larva has thus far escaped us, though 

 willow, its reputed food plant, has been closely searched. A 

 rarer moth, C. ccrogama, and somewhat earlier, has also es- 

 caped us in larval form, despite the fact that linden has been 

 under close observation. 



Among the rarer forms at Vinton is a Catocala somewhat 

 like pura, but a shade too dark and a species not unlike hcr- 

 mia. If there were enough variation in Catocala nnijiic/a both 

 of these forms might be considered varieties of that species, but 

 unijuga itself is rare at Vinton. 



To be seen in its beauty, Catocala concumbciis, the daintiest 

 of all the American species, must be bred, since even appar- 

 ently fresh specimens are usually torn or rubbed. Its habits 

 must be somewhat like those of epione, a species so dimcult to 

 get in a perfect condition. 



We imagine the larva of concumbens is of the cara type, 

 that is if it is a willow feeder.
