This form may be at once distinguished from the preceding by the 
fact that its fore-wings are twice as broad in comparison to their length, 
are perfectly clear, and have no very long cilia on their anterior mar- 
gin. It is a somewhat larger species and lighter in color. 
(3) COCCOPHAGUS LUNULATUS n. sp. 
In November, 1892, Mr. Coquillett sent to the Division some orange 
leaves thickly covered with the Eed Scale for use in the collections 
which were then being prepared for the Chicago Exposition. These 
leaves were carefully mounted, but as it would be some little time before 
they would be needed for the boxes, they were placed in a glass jar to 
ascertain whether they were parasitised. A week later a single para-

site issued which proved to be a typical Coccophagus (not an aberrant 
one like the preceding species), but belonging to an undescribed species. 
It is a very handsome form and is readily distinguished by its colora- 
tion no less than by its structural features from any of the other Eed 
Scale parasites.
