BRUES : NEW PHYTOPHAGOUS HYMENOPTEKA. 



263 



Scolioneura vexabilis, sp. nov. 



Length 9 mm. Broad and stout, dark colored or black with paler markings. 

 Abdomen ferruginous except at the base and apex. Dorsum of thorax indistinctly 

 pale around the edges. Antennae preserved only near the base, black; the joints 

 toward the base about five or six times as long as wide. Thorax as wide as 

 long, and not quite so wide as the oval abdomen, which is twice as long as 

 wide. Wings indistinctly infuscated towards the base, the veins brown. Anal 

 cell lanceolate, petiolate, as wide at its broadest part as three-fourths of the length

of the transverse median nervure. Marginal cell long and narrow, pointed at 

 apex ; apparently not divided by a nervure. First submarginal cell small, more or 

 less rounded at its base ; second and third long, each receiving a recurrent nervure ; 

 basal vein and first recurrent nervure widely divergent behind. 



Type. — No. 2039, Mus. Comp. Zool. , Florissant, Col. (No. 1520, S. H. Scudder 

 Coll.). 



This species might perhaps be excluded from Scolioneura, as I cannot make out 

 any cross-vein in the marginal cell. I can find no other suitable place, however, 

 and think that it may best be left here. The hind wings are not well enough pre- 

 served to show their venation, but the front ones are in good condition, with the 

 exception of a part of the apical portion. 



Selandria Leach. 



Brischke ('86) mentions the occurrence of a single specimen belonging to 

 Selandria in Baltic amber. Curtis ('29) compares a form from the lower Oligo- 

 cene at Aix with Selandria fuliginosa, but the latter is evidently the Tenthredo 

 fuliginosa now placed in Tomostethus Konow. 



Eriocampa Hartig. 



Cockerell ( : 06) has described Eriocampa wheeleri from Florissant, and there is 

 a second species to be added from the Scudder collection. The two may be 

 separated as follows : 



Second submarginal cell on the radius more than twice as long as the first 

 submarginal on the cubital side ; cross-vein in marginal cell strongly 

 oblique ; wings infuscated scudderi, sp. nov. 



Second submarginal cell on the radial side no longer than the first sub- 

 marginal on the cubital side. Wings hyaline wheeleri Ckll.
