Hosts 



I'vfds on till- leaves of Populus trrm- I'eeds on the l>ark of Willow (Salix 



uloides. larvigata Bebb. ), and is a subterranean 



form, or nearly so. 



Williams' description of the sjieeific clinraeters incliidin); the len^fths of the 

 antennal articles is deficient and a more extensive comparison is impossible. Tnn- 

 that in many ways the descriptions agree very well, but from the differenees given 

 above and esjiecially its habits, it seems to bi- a new species. 



FULLAWAYA n. sen. 

 Type F. saliciradicis n. sp. 



finrti/ - Robust forms, the body of the winged female narrow at head, but 

 mesothor.-ix, metathorax and aMomen nearly the same width. The l>ody of tin- 

 apterous fi-male widest at the middle and tapering to a point posteriorly and to a 

 rather broad front anteriorly. Coven-d with short fine hair and may or may not 

 lie slightly pruinosc. Large species. 



Ilrad — Considerably narrower than tli(- thorax, slightly |)oint<'d or straight 

 across the front, with very indistinct frontal tubercles, especially so in the apter- 

 ous fornvs. Covered with fine hairs. Nearly quadrangular in shape with the 

 anti-nna' arising from the sides near the front. 



Ei/rs — Large, with terete tubercles on the back margin. 



Antennae — In the winged form a little over half the length of the body, not 

 half so long as the body in the a|)lerous form: not reaching beyond the third 

 abdominal segment. .-Vrising from the front sides of the head on very indistinct 

 tubercles, or no tubercles at all. Covered with long hairs, each on a large tubercle. 

 Slightly imbricated and rough because of the hair tubercles. .-Xrticle I usually 

 shorter than IL never longer than II, though they may be coequal, I always 

 wider. III much longer than either IV or V, though not nearly so long as the 

 two together, not so long as \\. but longer than the spur, IV and V nearly sub- 

 equal, the former usually a little shorter; VI the longest article, the spur nearly 

 twice as long as the base and nearly coequal with articles IV and V, but usually 

 a little shorter that either. The transition from the base of VI to the spur is not 

 ,so great as in most a]>hids, the spur is nearly as wide as the base. 



Rostrum — Reaching nearly to the tip of the abdomen, to the tip or even 

 beyond the tip (in the wingc-d and young forms the rostrum may project beyond 

 the tip of the abdomen), but in the robust apterous forms it does not quite ri-ac-h 

 to the tip. Hairy along margins of the last joint. 



Prothnra.r — Wider than the head, nearly rectangular in shape, with l;irge, 

 semi-globular, lateral tubercles near the middle. 



Abdomen — With lateral smaller semi-globular and rather pointed tubercles 

 on each side. Practically all semi-globular in the apterous forms and two semi- 

 globular ones near the middle on each side of the winged forms, the remainder 

 rather pointed. Smooth, covered with fine hair, shiny or |)ruinose. 



Cornicles — Entirely wanting.
