Genus Monellia Oest. 



Monellia costalis (Fitch). (1855, p. 165.) Taken on hickory leaves? 

 New Haven, Conn., June 27, 1910, by W. E. Britton. Conn. No- 

 1-16/70. 



In order to determine positively whether or not the specimens 

 collected are this species the writer examined the Fitch collection 

 and located the type specimen still bearing the original number men- 

 tioned in Fitch's note book. Since there was only one specimen in 

 Fitch's collection and one specimen only referred to in his notes, 

 there can be positively no doubt about this specunen being the type. 

 Descriptive notes follow: 



Alate Viviparous Female: Antennal segments as follows: III, 0.352 mm.; 

 IV, 0.256 mm.; V, 0.256 mm.; VI (0.16 mm. + 0.176 mm.). Segment III with five 

 or six oval sensoria on the swollen 0.128 mm. of the segment. Abdomen with three 

 rather large rounded gibbous tubercles on each side of abdomen. Length of forewing 

 1.144 mm. Length from vertex to tip of abdomen 1.76 mm.

Key to the American Species of Monellia 

 (Alate viviparous females) 



1. Costal margin of wing with a broad brown band extending beyond the stigma, 



tibise yeUow, antenna annulated with brown costalis (Fitch) 



Costal margin of wing without such broad band though in some cases with 

 the costal vein brown 2 



2. Tibise, antennae and costal vein dark brown to black calif ornica Essig

3. Abdomen with rows of dark brown spots; the unguis of Segment VI of antennae 



longer than or equal to the base carya- (Mon.)
