 and only half as long as fourth, 5-7 equal and 3.5 times as long as 

 broad, 8-12 gradually shorter, last equal to fourth. Pronotum 

 truncate, truncation 0.4 width of head and emarginate above, usual 

 notches below with pubescent patches on front margin on sides. 

 Mesoscutum as long as broad, smooth, polished. Scutellum 0.72 

 length of mesoscutum, cup large, circular, reaching back 0.85 of its 

 length, depressed in front into septum between the two smooth deep 

 pits; cup with a thin whitish rim, a shallow circular depression on 

 top in which is a transverse pit near hind margin and a few punctures; 

 disk areolate, crenate behind and margined, overhanging meta- 

 thorax. Propodeum face perpendicular, carinae angled. Meso- 

 pleura smooth, separated from sternum by a carina and crossed 

 obliquely by a longitudinal ridge. Hind tibia equal to tarsus, claws 

 simple. Front wing hyaline, veins brownish, radial cell closed, 2.G 

 times as long as broad, cell to wing ratio 1 :4, first abscissa of radius 

 about half of second, areolet wanting, cubitus not reaching basal, 

 surface pubescent, margin ciliate, reaching beyond tip of abdomen. 

 Abdomen polished, normally compressed, longer than broad, second 

 tergite occupying entire length, with ring of hairs at base.

Kieffer, Das Tierreich, Lief. 24, p. 240. 



Genotype.— Tropideucoila rujipes Ashmead. Monobasic. 



Robust. Head not broader than thorax, cheeks margined, malar 

 space less than half eye and with groove, antennae arising above 

 middle of eyes, stout, submoniliform, third not distinctly longer 

 than fourth, 5-12 long oval, not twice as long as broad. Meso- 

 scutum with five longitudinal carinae which do not converge and 

 meet before reaching scutellum but remain distinct and parallel and 

 well separated clear to base of scutellum, the four broad grooves 

 between them shallow and polished, short grooves over fore wings. 

 Scutellum with two pits at base, cup large;, half width of disk, 

 longer than broad; disk sculptured and truncate. Mesopleura 

 separated from sternum by carina. Wing with open radial cell, 

 pubescent and ciliate. Abdomen with (not without, as stated by 

 Ashmead) a narrow circle of hairs at base, normally compressed. 



Related to Trisseucoela Kieffer, from which it is separated by 

 the ring of hairs at base of abdomen.
