LAPARA," Walker (1856). 



Type : Lapara bombycoides, Walker. 



7 A critical comparison between specimens of EUema Harrisii and a figure of Lapara bomby- 

 coides, executed in England, convinces me tliat tlie two species, if distinct, cannot be separated by 

 any uncomparative description. The fore wings in the drawing of L. bombycoides seem narrower, 

 with the external margin quite oblique, the apices more produced. So also the external 

 prominent dentatedly lunulate transverse band is more oblique, and its representation in the 

 picture gives it a more even general course ; whereas in Ellema Harrisii it is a little outwardly 

 bent opposite the cell, and there is a depression at submedian interspace. The hind wings appear 

 a little more rounded and the head more sunken in the drawing. But in every detail of size, 

 color and characteristic marking, there is so great a correspondence between the two that I am 

 inclined to believe that the drawing represents an individual of E. Harrisii, and I hope an occa- 

 sion will be soon offered for sending specimens of Ellema Harrisii to Loudon for verification. 



Hyloicus and Ellema appear to me to recall, sufiBciently strongly as to be noticed, certain 

 European Bombjxidae, such as Dendrolimus pini, which are considered by some authors as 

 typical of the latter family, but which have apparently no American representatives.
