seta, basal joint of hind tarsi much longer than the three fol- 

 lowing joints together. Abdominal pedicel in lateral view of 

 equal height throughout. Length about 1 mm. 



TTab. ]\rexico, collected amongst grass in cane-fields. (Koe- 

 bele). 



Polynema eucharis sp. nov. 



Yellowish brown or testaceous, transverse frontal ridge black, 

 abdomen darker than the thorax and darker on the more apical 

 segments than on the basal ones, the fonner being rather dark 

 brown. Legs yellow, tarsi more or less infuscate above. An- 

 tennae with the first three joints yellow, the two following less 

 clearly yellow and each with a minute basal black dot, three 

 following dark fuscous or blackish, the large club joint on its 

 wide surface, yellow. 



The head and pronotum are sculptured or punctate and bear 

 a white pubescence ; the pronotum is long; the rest of the thorax 

 very smooth and shining, impunctate or nearly, the parap- 

 sidal furrows distinct. Abdominal pedicel very elongate, fully 

 as long or a trifle longer than the hind femora and concolorons 

 with these, rather narrower near the apex than at the middle, 

 many times as long as wide, the rest of the abdomen smooth 

 and shining, nan-ow, elongate-ovate. Ovopisitor slightly ex- 

 serted (in dry specimen). 



Front wings rather more than three times as long as the 

 greatest width, very slender on more than the basal third, so 

 that the width at the base of the submedian fascia is not one- 

 third the greatest width of the wing, the apical margin blunt 

 and wide, their color white, the marginal vein nearly black, 

 and with a slight infuscation l)eneath it, a very conspicuous 

 dark fuscous, wide, submedian, transverse fascia, an equally 

 conspicuous but narrower anteapical one, the basal margin of 

 which is angulately indented aWmt the middle and the apical 

 side is angulately produced opposite the indentation; on the 

 dorsal side the fascia is bilobed, so as to include a large white 

 spot. Longest marginal cilia (near apex of dorsal margin) 

 about one-third as long as the wing-width. Clothing of dark 

 hairs regular over the wing surface and continued basally to
