of Membracids in the Cornell University collection for the loan 

 of which I am indebted to Professors MacGillivray and Bradley. 

 Mr. W. T. Davis of New Brighton, Staten Island, has sent me 

 for study a remarkably fine series of Membracids taken by him 

 in the vicinity of New York City. Interesting material has also 

 been received from Mrs. Annie Trumbull Slosson, Dr. E. D. 

 Ball, Dr. E. P. Felt, Prof. Franklin Sherman Jr. and others. 



The following synoptical table of the subfamilies of the 

 Membracidae is copied largely from that given by Canon Fowler 

 in the Biologia, which in turn was founded on that of Stal. 



Scutellum wanting or entirely concealed by the pronotum, i. 

 Scutellum distinct and more or less uncovered, with its apex 

 nearly always excavated or broadly sinuated and furn- 

 ished on each side with acute angles, 



6, Centrotida Stal. 



Tarsi of equal length or the posterior pair longest, 2. 



Posterior tarsi much shorter than the . anterior and inter- 

 mediate, 4, Hoplophorida Stal. 



Tibiae, at least the anterior and intermediate, dilated or 

 foliaceous, 5. Membracida Stal. 



Tibiae simple or very slightly dilated, never foliaceous, 3. 



Third apical or terminal areole of the corium elongated, 

 never petiolate, 3, Darnida Stal. 



Third apical or terminal areole of the corium petiolate, the 

 adjacent areoles contiguous before it, 4. 



Elytra externally broadly coriaceous and opaque, with the 

 veins of the coriaceous portion scarcely distinguishable 

 and the free margins broad. 1, Tragopida Stal. 



Elytra entirely membranous with the veins distinct, or 

 coriaceous and punctured at the base only. 



2, Smiliida Stal 



Subfamily Tragopida Stal. 



This subfamily is distinctively South American in its 

 distribution. But three species extend their range so far north 

 as Panama. Goding in his catalogue credits Tragopa dimidiata 

 Fairm. to the West States, quoting Riley, but this is almost 

 certainly an error of determination and I prefer to omit it 

 entirely from our fauna.
