anterior parallel lines fine, raised, distinct, especially posteriorly; scutel- 

 lum rather narrow, median raised area about as in utahensis, or more 

 depressed anteriorly; abdomen of moderate length, the second segment 

 covering one-half to two-thirds of the area ; legs almost uniformly rufous 

 brown; areolet of moderate size or smaller, smaller than in utahensis 

 or plana; first abscissa of the radius slightly heavier than in either 

 utahensis or plana. 



MALE. — Differs from the males of other varieties as follows: 

 Parapsidal grooves hardly more than gradually convergent posteriorly; 

 median groove rather long and continuous posteriorly; areolet of mod- 

 erate size or smaller. 



GALL. — Does not differ particularly from the galls of other va- 

 rieties. 



RANGE. — Washington: Pullman. Probably confined to a small 

 region about the Coeur D'Alene and Moscow Mountains of the Idaho and 

 Washington boundary. 



TYPES. — 6 females, 2 males. Holotype female, paratype females, 

 and males at The American Museum of Natural History; paratype 

 female with the author. From Pullman, Washington; Melander col- 

 lector; parts of American Museum numbers 24633, 24660, 24661. 



The smaller areolet and less convergent parapsidal grooves 

 will distinguish the types of this variety from utahensis, 

 which it closely resembles. But material from the same col- 

 lection appears to include typical utahensis and several grades 

 of intermediates with diver-gens. This variation cannot be 

 dismissed as liable to occur in any locality or between any two 

 localities. I have 4077 insects of utahensis, from two local- 

 ities sixty miles apart. No individual of the lot varies toward 

 the typical divergens from Pullman. Either the Pullman ma- 

 terial represents both varieties, v/ith interbreeding where the 

 ranges meet; or utahensis at Pullman is tending toward the 

 development of another variety not yet completely isolated. 

 In either case the distinct thing should be recognized. More 

 material from the region may illuminate the question. 



Beutenmuller's 1907 description of utahensis fits divergens, 

 and was probably based on this same Melander material. Con- 

 trary to the statement made there, the gall of this or of any 

 other variety is not distinctive, unless in average size. 



Diplolepis variabilis (Bassett) 



FEMALE. — Mesonotum sculptured posteriorly between the parap- 

 sides; scutellum without foveas; second segment of abdomen very large, 

 produced dorsally; radial area heavily shaded, clear centrally. HEAD: 

 Fully as wide as or slightly wider than the thorax, hardly enlarged 

 behind the eyes; blacky the mouth parts brighter; coriaceous to finely
