 Labelled Placerville, California; March 30, 1920: Kinsey collector. 



Adults were emerging from these galls at Placerville on 

 March 30, 1920. 



Andricus spectabilis variety ukiahensis, new variety 



FEMALE. — Differs from the females of other varieties of the 

 species as follows: Parapsidal and median grooves not especially broad- 

 ened at the scutellum; median groove distinct, but usually shorter than 

 in variety spectabilis; anterior parallel lines very fine, basal foveas of 

 the scutellum very largely rugose, more so than in variety spectabilis ; 

 mesopleurse entirely smooth beneath the tegulae, coarsely coriaceous, even 

 somewhat aciculate centrally. 



GALL. — Does not differ from the galls of the other varieties. 



RANGE. — California: Ukiah. Probably confined to a small region 

 of the north Coast Range country. 



TYPES. — 13 females, 8 galls. Holotype female, paratype galls at 

 The American Museum of Natural History; paratype females and galls 

 at Stanford University, the tJ.S. National Museum, and with the author. 

 Labelled Ukiah, California; March 17, 1020; Kinsey collector. 



The insects did not emerge until some time after collecting 

 at Ukiah on March 17, 1920. 



The very distinct nature of the anterior parallel lines 

 would separate this variety even if other characters were 

 lacking. 



Compsodryoxenus brunneus Ashmead 



FEMALE. — Head wider than thorax; antennae with 13 segments; 

 mesonotum rather transversely rugose. HEAD : Wider than the thorax, 

 distinctly enlarged behind the eyes; brownish rufous, finely coriaceous, 

 finely rugose toward the mouth, naked except near the mouth. Antennae 

 brown, the first four or five segments golden yellow; with 13 segments, 

 the second short but more elongate than globose, the third not much 

 longer than the fourth, the last half again as long as the preceding. 

 THORAX: Wholly brownish rufous, darker on the scutellum and on 

 the sides; mesonotum finely rugose, rather transversely so, naked; parap- 

 sidal grooves fine, shallow, lost in rugose areas before reaching the 

 pronotum; median groove lacking; anterior parallel lines very fine; not 

 prominent; lateral lines fine, shallow; scutellum decidedly longer than 

 wide, well rounded posteriorly, wholly, rather finely rugose, with two 

 shallow depressions anteriorly indicating small, shallow, rugose foveae; 

 pronotum roughened laterally, hardly rugose; mesopleurae mostly cori- 

 aceous, suggesting an aciculation in places, smooth on the posterior and 

 ventral margins. ABDOMEN: Brownish rufous, lighter basally, much 

 darker posteriorly especially dorsally; entirely smooth and naked; not 

 longer than high, protruding somewhat ventrally, the hypopygium well 

 developed, plow-shaped, the spine not long, fine, and slender; ventral
