suggests that inasmuch as the December galls contained larvae 

 as v/ell as pupse emergence may be distributed over two years. 

 Altho Patterson cut into a great many of the galls of 

 melanicus he found no indication there of differences in emer- 

 gence. 



This variety is readily distinguished from melanicus by the 

 lighter color and the distinctly narrower parapsidal grooves ; 

 from the variety on my rti folia it is best distinguished by the 

 anterior parellel lines which diverge posteriorly and the fovese 

 which are much broader and wholly smooth. 



The galls which Weld recorded from Daytona, Florida, 

 occurring on Quercus myrtifolia, and which were also included 

 in the paratypes of ovatus, belong to a distinct variety. 



Andricus ovatus variety melanicus, new variety 



FEMALE. — Shows the following characters in addition to those 

 common to all varieties of the species: Color of head, thorax, and 

 abdomen dark chestnut rufous; antennae almost entirely brown, very 

 dark terminally, the first two segments rich rufous; parapsidal grooves 

 distinctly broader and more rugose at the scutellum than in ovatus, con- 

 verging more closely posteriorly; anterior parallel lines rather close 

 together anteriorly for almost half the length, almost twice as wide 

 apart posteriorly; the scutellum relatively much longer, the foveas large, 

 broad, broader laterally, mostly smooth but irregularly ridged at bottom, 

 separated by a wider rugose area than in ovatus; mesopleurae beneath 

 the tegulae very finely puncto-rugose, front and middle pairs of legs rich 

 rufous, tibiae lighter, hind legs very dark rufo-piceous, sometimes in part 

 black, the tibiae lighter ; areolet of moderate size. 



GALL. — Quite the same as those of the other varieties; more often 

 fused to the very tips; on Quercus Schneckii. 



PvANGE.— Texas: Austin. 



TYPES.— 55 females, 16 galls (in 3 clusters). Holotype female, 

 paratype females, and galls at The American Museum of Natural His- 

 tory; paratype adults and galls with the author; paratype adults at the 

 U.S. National Museum, the Museum of Comparative Zoology, the Phila- 

 delphia Academy, and Stanford University. Labelled Austin, Texas; 

 February 7, 1922; Q. Schneckii; Patterson collection number 156. 



Patterson found adults emerging on February 7, 1922. 



This variety is readily distinguished at a glance by its dark 

 color; it is distinguished from both other varieties by the 

 much broader parapsidal grooves which converge more closely 

 posteriorly; and it is further distinct from the variety on 

 myrtifolia in having very broad, largely smooth fovese.
