" Georgia." A '^ specimen sent me through Mr. v. Meske from 

 Texas (coll. Heiligbrodt) seems to belong to this species. It is less dis- 

 tinctly marked than the figure, else nearly resembles it. 



Carl Cleyer is to be regarded as authority for the species in these 

 fourth and fifth Hundreds, concluding the work. The date of the first 

 Hundred is 1818; of the second, 1823; third, 1825: fourth, 1832; fifth, 

 1837. The total number of figures is 1,000, each example being figured 

 in two positions separately numbered ; each Hundred contains two hun- 

 dred figures.

Galls : Densely hairy hemispherical masses attached by a single small 

 point to the upper or under surface of the leaves of an unknown species 

 of oak found in Arizona. They are from one-half to three-fourths of an 

 inch in diameter. One specimen in my collection is nearly globular, but 

 all the others are hemispherical, the fiat side lying close upon the surface 

 of the leaf The woolly hairs are of a dull russet color and entirely hide 

 the polythalamous gall beneath. Denuded of the hairs the surface of the 

 gall is uneven, and beneath the slight protuberances lie the larval cells. 

 The shell or rind is brittle, and when dry crumbles easily. The inside is 

 nearly filled by the small and extremely thin-walled larval cells. Between 

 these there are a few thin fibrous plates or lamina with open spaces. A 

 gall of average size contained fourteen larval cells. 



Gall-Hies : All females. Head black, vertex finely rugose or punctate. 

 Ocelli rather large : the middle one lies in a smooth shallow groove which 

 extends from the posterior margin of the vertex nearly to the base of the 

 antennae, and is broader behind than before. Face microscopically 

 wrinkled and hairy. Antennae 14-jointed, extremely slender or thread- 

 like : 1st and 2nd joints short and comparatively stout, the 2nd nearly as
