March in breeding cage) to crawl down to base of same sprouts and 

 lay eggs to produce this radicola gall in the spring. This cycle is not 

 proven, and it remains for others to work out the details of the life 

 history. Brodie was the first to suggest a connection between the 

 fig gall and a root gall when in Annals of Report of Clerk Board 

 Forestry, Ontario, 1896 (pp. 114-116), he says forticormis burrows 

 into ground finding rootlets a few inches down in which they oviposit 

 and in which are formed subterranean galls, but he does not describe 

 them further. Radicola is not on "rootlets, " but at base of tree. 



In the forest insect collection at the United States National Mu- 

 seum are three males and three females of what seem to be this 

 species reared in March, 1897, at Shovel Mount, Texas, by F. G. 

 Schaupp "on roots of post oak." 



9. TRIGONASPIS FUMOSA, new species. 



Female. — Dark brown, front legs and thorax lighter. Head 

 broader than thorax, ver} x finely rugose, pubescent on face, clypeus 

 truncate and reflexed, interocular space measured at top less than 

 1.1 times as broad as high, malar space .43 eye and with malar groove, 

 antennocular space equal to ocellocular, palpi 5- and 3- segmented, 

 mandibles with two sharp teeth, antennae 14-segmented, third longest, 

 last not one and one-half times preceding, distal third not thinner. 

 Pronotum smooth. Mesoscutum smooth and polished with two 

 percurrent parapsides, no trace of lateral or anterior lines and no 

 median although so transparent that the dark space between two 

 underlying muscles might be mistaken for one. Scutellum finely 

 and evenly rugose except for a small polished area on disk, with a few 

 scattered punctures, six-tenths width of head, transverse arcuate 

 furrow at base with faint median ridge, not margined behind, with 

 two impressed areas on sides. Propodeum with two outwardly bent 

 ridges inclosing an area smooth in center nine-tenths as broad as 

 high, narrowed at top to two-thirds its widest width. Spiracular 

 areas rugose, punctate, spiracles elliptical. Mesopleura smooth and 

 polished except for finely striate area above, sparsely pubescent 

 below. Legs pubescent except for bare areas on coxae, hind tarsi 

 shorter than tibiae with second longer than fifth and claws with tooth 

 Wings clear with distinct brown veins, areolet present, surface 

 pubescent except at base, margin ciliate. Abdomen smooth and 

 polished, second segment with scattered pubescence on sides. Ven- 

 tral spine tapering and in balsam slightly spindle-shaped. Ovi- 

 positor when dissected out not three-tenths length of antenna, ova- 

 rian eggs well developed. Using width of head as base, the length 

 of mesonotum ratio is 1.46; antenna, 3.6; ovipositor, 1.3; wing, 4.7. 



Male. — Thorax and legs darker than in female. Antennae with 

 third segment strongly bent, broken but probably 15-segmented.
