FEMALE. — Head enlarged behind the eyes; antennae with 14 or 15 

 segments; mesonotum never wholly smooth, often puncto-rugose, hairy; 

 fovese present; tarsal claws simple; anterior margins of wings not 

 ciliate; radial area open. HEAD: About as wide as the thorax, con- 

 siderably enlarged behind the eyes in the agamic female, usually by a 

 distance equalling the width of the eyes; slightly enlarged behind the 

 eyes in the bisexual form; malar space about one third the length of 

 the compound eyes in the agamic female, less in the bisexual forms, 

 especially the males; face without aciculations ; no malar furrow; more 

 or less finely puncto-rugose, largely hairy, most hairy and rugose on 

 the face; rufus to black, the tips of the mandibles piceous. Antennae 

 golden rufous to black, often the seven or eight terminal segments 

 darker; only finely pubescent, usually rather long, usually not much 

 enlarged terminally; with 14 or 15 (or rarely 16) segments, the second 

 the shortest segment but distinctly elongate, the third only somewhat 

 longer than the fourth, the last hardly longer than the preceding, some- 

 times longer and with another division. THORAX: Mesonotum mostly 

 finely punctate, puncto-shagreened to puncto-rugose, never roughly 

 rugose, naked or more usually largely hairy; parapsidal grooves often 

 fine, shallow, often discontinuous, indistinct, or faintest anteriorly, gradu- 

 ally converging posteriorly; median groove more or less faint or re- 

 duced, or lacking; anterior parallel lines lacking or in part indistinct or 

 distinct; lateral lines smooth; scutellum longer than wide, moderately 

 rounded posteriorly, coriaceous to rugose, hairy; foveae always present, 

 more or less distinctly separated ; pronotum laterally striate rugose ; 

 mesopleurae in part smooth, shining, and naked, in part punctate, puncLo- 

 rugose or rugose aciculate, often hairy. ABDOMEN: Mostly smooth 

 and naked, sometimes sparsely hairy, sometimes finely punctate or reticu- 

 late, somewhat shorter to slightly longer than high, not produced dor- 

 sally, the second segment covering less than a half to two-thirds of the 

 area, its edge more or less slightly oblique and much rounded ventrally; 

 ventral spine not long, slender; ventral valves toward the vertical. 

 LEGS: Brownish rufous, in part darker especially on the hind tibiae, 

 entirely golden yellow in the bisexual forms; tarsal claws rather fine, 

 simple. WINGS : Entirely clear, pubescent, the anterior margins not 

 ciliate or short ciliate; veins brown, only the subcosta and cross veins 

 ever heavy; areolet very small to very large; cubitus continuous or dis- 

 continuous; radial cell open, rather long, the second abscissa of the 

 radius moderately curved ; the first abscissa distinctly, sometimes sharply, 

 angulate, with or without, usually without a projection, sometimes very 

 limitedly infuscated. LENGTH: 1.2-3.5 mm. 



GALL. — A more or less gradual, woody swelling, on stems, leaves, 

 or flowers. Polythalamous, varying from a very few to a great many 

 'cells in a gall. The swelling usually elongate, less often globose, usually 

 arising gradually, surrounding and involving the affected parts; covered 

 with normal epidermis mostly of normal color and texture. Internally 

 woody, the tissue increased but not otherwise greatly modified, the larval 

 cells with only a more or less distinct lining, in some cases solidly im- 

 bedded, sometimes with the cells in a more or less continuous cavity in 

 the wood, each cell distinct, adjoining the next, but inseparable; some-
