grooves distinct, smooth at bottom, not quite as wide as in piignus, prac- 

 tically obsolete for the anterior half of the mesonotum; a short median 

 groove just evident; anterior parallel lines not entirely smooth; meso- 

 pleurae piceous black, mostly smooth and naked beneath the tegulae, 

 medianly finely rugoso-punctate and hairy; foveae rather larger, mostly 

 smooth and shining but very sparingly rugose at bottom; abdomen in 

 part rufous brown, banded rufo-piceous about the edges of the second 

 and third segments, and generally dorsally and ventrally, not as long as 

 high; legs dark rufous or chestnut, the coxae basally, the tibiae, and tarsi 

 brown, the hind tibiae almost black; first abscissa of the radius broadly 

 infuscated at the subcosta; areolet of moderate size or larger, distinctly 

 larger than in j^^^Gf^us; cubitus about continuous; length 2.5-3.5 mm., 

 averaging larger than in jmgnus. 



GALL. — Very similar to the gall of pugnus, irregular, knotted, up 

 to 18. mm. in diameter and 60. mm. long; internally solid, woody, the 

 larval cells closely embedded; on Quercus lobata. 



RANGE. — California: Santa Rosa. Probably confined to a more 

 northern part of the range of Quercus lobata. 



TYPES. — 10 females, 14 galls. Holotype female, paratype female, 

 and galls at The American Museum of Natural History; paratype fe- 

 males and galls at the U.S. National Museum, Stanford University, and 

 with the author. Labelled Santa Rosa, California; March 16, 1920; Q. 

 lobata; Kinsey collector. 



Many of the insects had emerged before collecting on 

 March 16, 1920, at Santa Rosa. 



This variety, in both insect and gall characters, much more 

 closely resembles pugnus than any other variety of the species. 

 Pugnoides is readily distinguished by the darker mesopleurse, 

 the larger areolet, and the distinctly larger size. The range 

 of this variety appears to be intermediate between pugnus 

 and garryanse. Garryanx shows somewhat close relation- 

 ships to pugnoides. 



Plagiotrichus chrysolepidicola variety garryanae, new variety 



FEMALE. — Shows the following characters in addition to those 

 common to all varieties of the species: Color generally chestnut brown, 

 with considerable black; antennae brown, the first tvv'o segments brown- 

 ish rufous, the last eight almost black; parapsidal grooves distinct for 

 half the mesonotal length, barely evident anteriorly; median groove 

 barely indicated for the mesonotal length, but not at all definite; an- 

 terior parallel lines distinct; mesopleurae largely smooth and naked, 

 medianly rugoso-punctate and hairy; foveae rather small, wholly rugose; 

 abdomen for the most part dark rufous brown to black, lighter rufous 

 only latero-basally, not very hairy laterally, not as long as high ; legs 

 including the coxae bright rufous, the tibiae and tarsi brown, the hind 

 tibiae very dark; areolet rather small or distinctly small; cubitus not 

 quite continuous; length 2.2-2.7 mm.
