bright rufo-ferruginoHS. Antennae rufous beneath. Wings hyaline (but not clear), 

 strongly iridescent; venation pale brown, base of stigma and costa pallid to pale yel- 

 lowish. 



Male. — In general the male agrees with the female. The ocellar basin is indi- 

 cated by a shallow depression around the anterior ocellus. There is also a depression 

 between the lateral ocelli. The apical antennal joint is shorter than the preceding 

 one. The hypopygium is long, extending beyond the apex of the abdomen and is 

 rather sharp at the apex. The antennas are largely rufo-ferruginous. The stigma is 

 paler brown than in the female. 



Habitat. — \\\., N. Y. (Norton) ; Canada (Jarvis). 



The above description was drawn up from a ^ and 9 received 

 from the U. S. National Museum. 



" The gall is found on S. longifolia. A mere gradual enlargement 

 of the twig, from one fourth more than its normal diameter up to twice 

 its normal diameter, almost always without any roughness on the exter- 

 nal bark ; general color that of the twig. 



'■^ Larva. — August 23 the larva is 20-footed. Color pale green- 

 ish-white, with the mouth dark and the usual eye spots. Length 

 al)0ut 0.15 inch" (4 mm.). [Walsh through Norton.] 



The bright livery of this species should help in its determination. 



9. Cryptocampus macgillivrayi, new species. 



Enura salicis-nodus Weldon, Can. Ent., xxxix, Sept., 1907, p. 286. 



Female. — Length 6 mm. ; length of anterior wing 6 mm. Head seen from 

 the side narrowed toward occiput. Clypeus shallowly, circularly emarginate ; lobes 

 broad, obtusely rounded. Antennal foveae large below the antenna;, middle fovea 

 elongate, deep, open at the top. Ocellar basin shallow, large, walls sharply raised. 

 A line-like furrow from lower ocellus to frontal crest. Frontal crest rather strong, 

 slightly broken in the middle. Interocellar furrow wanting ; lateral ocellar furrow 

 indicated by a broad, elongate fovea. Third antennal joint slightly longer than the 

 fourth, apical joint tapering, a little longer than the preceding joint. Ocellar area 

 finely granular. Middle lobe of mesonotum finely denticulate, middle furrow strong 

 for anterior half. Mesopleura; highly polished. Claws deeply cleft, inner tooth much 

 shorter than outer so as to give the appearance of having a large inner tooth. Vena- 

 tion normal or the lower discal cell of hind wings is large and extends beyond the 

 upper. Stigma elongate, rounded on the lower margin, tapering usually to an acute 

 tip, although it is sometimes very slightly truncated. Sheath not very broad, trun- 

 cated at apex, sides subparallel. Cerci as long as or longer than the sheath. Bright 

 rufo-ferruginous : basal two thirds of the antennae, small spot about ocelli, spot on 

 middle lobe of mesonotum, spot on lateral lobes of mesonotum sometimes, apex of scu- 

 tellum, metanotum, margins of basal plates and apex of the sheath, black. Wings 

 hyaline, iridescent ; venation pale brown, costa and basal two thirds of stigma 

 white. 



Male. — Length 5.5 mm.; length of anterior wing 5.5 mm. Head seen from 

 above quadrate, seen from the side not narrowed toward occiput. Clypeus rather
