2. Areolet present, median and submcdian cells of equal length. 



L. stygialis, sp. nov. 

 Areolet wanting, submedian cell longer than the median. 



L. tenebrosa, sp. nov. 



Lampronota pristina, sp. nov. 



Female. Length about 9 mm. Ovipositor 10 mm. Head and thorax 

 blackish, probably rufo-piceous; abdomen lighter, probably dark ferruginous 

 or pale rufous. Head not preserved; antennae long and slender; basal flagel- 

 lar joint about twice as long as thick; apical ones distinctly longer than thick. 

 Thorax smooth and shining; metathorax regularly, but not completely areo- 

 lated; with two transverse carinae, a median one between these, and a lateral 

 one from the second transverse to the apex. Abdomen slender, smooth and 

 shining. Ovipositor very long, equal to or somewhat greater than the length 

 of the body. Legs rather stout, brownish. Wings subhyaline, veins and 

 stigma fusco-piceous, the latter subovate. Areolet present, triangular and 

 subsessile above; recurrent nervure received midway between the first and 

 second transverse cubitus; discocubital vein curved, more sharply so at the 

 middle, but not broken. Median and submedian cells of equal length. 



Type.— No. 2131, M. C. Z., Florissant, Col. (No. 16,369, S. H. 

 Scudder Coll.). 



There is another specimen received later from Professor Cockerell 

 which appears to be the same collected at Station 14. However the 

 ovipositor of the latter is apparently very distinctly shorter and it may 

 represent a different species. 



Lampronota stygialis, sp. nov. (Fig. 33.) 



Female. Length 5 mm. Ovipositor 1.6 mm. (or more?). Head and 

 thorax black, abdomen except base ferruginous. Antennae very slender and 

 rather long; basal joints 

 very long, the first flagel- 

 lar joint about five times 

 as long as thick; thence 

 growing smaller, the sixth 

 a little more than twice as 

 long as thick and the ones 

 toward the apex only one- 

 half or one-third longer 

 than wide. Thorax 



smooth and shining; the metanotum very incompletely areolated, but it is 

 so crushed in the specimen that one cannot make out the position of the one
