ART. 19. GAUL-FLIES OF THE FAMILY CYNIPIDAE WELD. 29 



and closest to halanoides. As the tarsal claws seem to be simple, the 

 species is here transferred to CalUrhytis. 



Genus ANDRICUS Hartig. 



ANDRICUS FIMBRIATUS. new species. 



Plate 1, fig. 3, and plate 3, fig. 11. 



Agamic female. — Black, flagelliim and legs brownish. Head as 

 broad as thorax, frons coriaceous, face smooth with setigerous punc 

 tures, pubescence white, seen from in front widest above antennae, 

 facial line .74 transfacial, intercular area 1.36 times as broad as high 

 antennocular less than ocellocular, malar .5 eye and without groove 

 seen from above widened behind eyes, thickness .43 width with occi 

 put only slightly concave, mandibles 2-toothed, palpi 5- and 3-seg- 

 mented, antennae 13-segmented, third longest, 4-6 subequal and 

 three-fourths third, decreasing to 12, last twice as long as preceding. 

 Thorax with white pubescence but not hiding sculpture. Meso- 

 scutum broader than long, shining, finely coriaceous in balsam with 

 setigerous punctures, parapsidal grooves deep, smooth, narrower 

 and vanishing in front, their separation behind equal to that at 

 hind end of the smooth anterior lines, median not reaching to an- 

 terior lines. Lateral lines bare. Scutellum becoming rugose be- 

 hind, pits at base smooth, deep triangular impressions on sides. 

 Carinae on propodeum slightly bent out and inclosing a smooth area 

 narrowed a little above. Mesopleura with large bare polished area- 

 Hind tarsus equal to hind tibia, second shorter than fifth, claws with 

 tooth. Wings hyaline, veins brownish, first abscissa of radius curved, 

 radial cell ratio (length divided bj^ width) 3.4, areolet reaching one- 

 fifth and cubitus three-fourths way to basal, surface pubescent, mar- 

 gin ciliate. Abdomen longer than broad, slightly compressed, 

 sm.ooth and shining, second tergite occupying about four-fifths and 

 the third the rest, second with narrow pubescent patches at base, 

 the hind margin making an angle of 45 degrees, ventral spine hori- 

 zontal, in balsam 3.75 times as long as broad, ovipositor when dis- 

 sected out one and one-half times antenna, ovarian eggs well de- 

 veloped. Using width of head as a base the length of mesonotum 

 ratio is 1.38, antenna 2.0, ovipositor 3.1, wing 3.89. 



Length of 13 pinned specimens 2.75-3.5 mm. Average 3.2 mm. 



Runs in the Tierreich key to pj'uiriostis Bassett, from which it is 

 distinguished by its larger size, darker veins, larger areolet, and 

 longer cubitus. 



Type.— Cat. No. 23225, U.S.N.M. Seven cotypes. 



Host. — Quercus hicolor Willdenow.
