Inasmuch as my specimens were collected in a natural forest 

 some distance from artificial plantings, and further that the 

 Monell specimens were also collected, in a natural timber, the 

 indications are that it is a native of the United States. 



This species is especially interesting because it is closely re- 

 lated to Drepanaphis Del Guercio* and Callipterus Koch, and 

 is apparently the connecting link between the two genera. The 

 size and general appearance of the insect places it in the genus 

 Callipctrus, while the antennal tubercles, antennae and legs are 

 those of Drepanaphis. The style and wings and its habits are 

 characteristic of both genera, while the cornicles are inter- 

 mediate. 



Winged vipiparous female Head (PI. VIII, fig. i), and the thorax 

 brownish (nearly black in old individuals), abdomen pale yellowish with 

 a slight greenish tint. Eyes red. Ocelli conspicuous. Antennae with 

 the two basal segments concolorous with the head, and the remaining 

 segments whitish ; set on rather conspicuous tubercles ; very long and 

 thread-like, being fully three times the length of the body ; segment I 

 stout and robust, more than twice as long and one-half broader than 

 II ; filament VI is extremely long and thread-like, and easily broken, 

 about two and one-half times as long as III and nearly fourteen times 

 the length of base VI; III nearly one-half longer than IV; IV and V 

 subequal, V being invariably slightly the longer; two (occasionally one 

 or three) comparatively large circular sensoria near the base of III, 

 the usual one at apex of V and several at apex of base VI ; the tran- 

 sition between base and filament of VI gradual. (PI. VIII, fig. 2). Beak 

 not reaching the coxae of the second pair of legs. Wings callipterous- 

 like, hyaline, and with pale brown veins ; the first and second discoidal 

 branching at a distance varying from one-third to nearly one-half (more 

 often the former) the distance from where the third branches to the 

 tip of the wing ; stigmal vein curved at the base, then runs straight to 

 the margin of the wing. (PI. VIII, fig. 3). Legs frail and entirely whit- 



*Drepanaplns n. g. was described by Dr. G. Del Guercio in the "Re- 

 vista di Patologia Vegetalc," Anno IV, no. 4, August, 1909, from speci- 

 mens of the so-called Drephanosiphum acerifolii Thos., sent him by 

 the writer. Phynwtosiphnni n. g. was proposed by the writer for the 

 same genus in the Annals of the Entomological Society of America, 

 September, 1909, not knowing of Del Guercio's description the month 

 previous.
