 E. querci, new species. 



Female. — Length 2.5 mm., expanse of wings 4 mm., greatest width of fore-

A male specimen with corresponding characters, although from a 

 different lot (Lot 509, s. 20 ex fuzzy gall of Callirhytis lasia Ashm.

DECATOMA Spinola. 

 D. kelloggi, new species. 



Female. — Length 2.75-3 mm., expanse of wings 4.35 mm., greatest width of 

 fore-wing .92 mm. Head and thorax (including petiole) umbilicately punctate, 

 thickly clothed with whitish pubescence, which is lengthened on the meso- 

 sternum, mesopleura below and anteriorly on metathorax into a silvery fringe. 

 The sculpture of the face, cheeks and petiole is rather shallow, mesopleura 

 aciculate, abdomen smooth and shining with a few sparse hairs. Head slightly 

 wider than the thorax, transverse and fairly thick anterior-posteriorly, eyes 

 small, face broad, cheeks emarginate, front wide between the eyes, ocelli 

 arranged in an obtuse triangle, antennae inserted on level with lower margin of 

 eyes, rather broad and deep antennal groove on face almost reaching lower 

 ocellus, antennae 9-jointed (one ring-joint and an undivided club). Thorax 

 convex, almost tuberculate, pronotum as long as the mesonotum, parapsidal 

 grooves present but indistinct, scutellum rounded posteriorly and very convex, 

 metanotum sloping abruptly, with a shallow fovea at the base smooth and shin- 

 ing. Abdomen compressed, elliptical from above, triangular from the side, 

 petiole fairly long and broad, only five segments visible, 3d the widest, ventral 

 valves evident but not protruding. Legs pubescent, hind tibiae very thickly 

 clothed with stiff white hairs, hind coxae and femora very much swollen, a few 

 long hairs on the former.

 two lateral and two transverse stripes on the pronotum, mesonotum largely,
