176 THE CANADIAN ENTOMOLOGIST. 



Euura bracJiycarpce, n. sp. — ^ . Length about 5 mm. Head with 

 a few fine punctures on vertex. Clypeus shallowly emarginate, lobes 

 broad, rounded, antennal foveae large and deep ; middle fovea (antennal 

 fovea of Marl. Rev. Nematinse of N. Am.) elongate, well defined, ocellar 

 basin shallow, better defined by the lower wall ; a slight depression around 

 each lateral ocellus; 2nd, 3rd, 4th, 5th joints of antennae subequal ; 

 thorax smooth, shining; tarsal claws cleft, rays subequal ; intercostal vein 

 its own length before basal ; discal cells of hind wings equal on the outer 

 margin, the lovver one is much broader than the upper; sheath broad, 

 rounded on lower apical margin ; cerci long and slender ; apex of 

 abdomen and sheath with long white hairs. Colour shining black ; 

 mandibles, except apex, which is piceous, labrum, edge of clypeus, teguloe, 

 small spot on angle of pronotum ; legs, except bases of coxae and a line 

 on femora, beneath clear reddish-yellow ; apex of venter is sometimes 

 piceous; wings hyaline; nervures brown; costa and base of stigma 

 pallid. 



The ^ does not differ much from the $ ; the apical joints of the 

 antennae are rufous, the costa is darker, the femora are usually darker, the 

 posterior are sometimes piceous, and the posterior tarsi are usually 

 infuscate. 



One % has the posterior and upper orbits ferruginous, and the 

 superclypeal area and whole of clypeus reddish-yellow. The upper orbits 

 in a good many specimens are rufous. 



Hab. — Florissant, Colo., between June 16 and July 24, 1907, but 

 mostly on July 7, '07, when the type was collected. "On Salix brachy- 

 carp(z''' (S. A. Rohwer). An Euura gall, common on this Salix at Floris- 

 sant, and the only one I found there is much like Euicra saiicis-ovufn, and 

 I think it must be the gall of Euura bachycarpce^ although no adults were 

 raised. 



This species is most nearly related to E. albirida, Cress., but may be 

 known from that species by being larger, having no testaceous spot 

 between eyes, the posterior angle of pronotum being reddish-yellow, and 

 the black of the femora in the V being a line beneath. 



Euura parva, n. sp. — $ . Length about 3^ mm. Head with small, 

 rather dense punctures, vertex rounded ; clypeus circularly emarginate, 

 lobes broad, rather pointed ; antennal foveas rather deep, longer below 

 antennae ; middle fovea elongate open at the top ; ocellar basin very 

 shallow at the top, but fairly distinct nearer the antennae ; 3rd and 4th
