tinctive characteristics and relationships of this species are 

 discussed in connection with my proposal of the synonymous 

 name, canadensis. 



Alveotingis grossocerata O. & D. 



Osborn and Drake described this remarkable species from 

 a brachypterous example 5 and later 6 I published an account 

 of the macropterous form, although the specimen lacked the 

 characteristic antennae, except for the basal segments. It 

 is, therefore, a pleasure to record another example of this 

 long-winged phase, which still retains its antennae, shaped 

 just as in the brachypterous form, and which agrees in every 

 particular with the mutilated specimen formerly described. 

 This individual, labeled probably by Uhler with the MS 

 name "Rhombodia areolata Uhl.," was collected by Mrs. 

 Slosson at Franconia, N. H., and is preserved in her collec- 

 tion. 



Melanorhopala clavata Stal. 



During the summer of 1919 I met with numerous specimens 

 of this species, the sexes occurring together and in approxi- 

 mately equal numbers. In every case the male individuals 

 exhibited the characters on which I based M. obscura, and 

 thus the synonymy proposed in a recent paper 7 of mine is 

 corroborated. No material variation tending to obliterate 

 this unusual sexual dimorphism has been observed. 



Melanorhopala infuscata Parshley. 



Gibson has recently sent me for determination an example 

 of this species, which merits notice since it is the only known 

 specimen beside the type series. It was taken by R. C. 

 Shannon near Plummer's Island, Maryland, August 5, 1914, 

 at "tulip poplar sap." The scant evidence at hand indi- 

 cates that this species, unlike most Tingids, lives on the bark 

 of Liriodendron, subsisting, perhaps, on sap from the trunk 

 rather than from the leaves.
