Kiiisey: Studies of Cyriipidse

The differences between the varieties variabilis and sctdpta 

 are not great, but in all of the nearly six hundred individuals 

 which I have examined only four are not clearly one thing or 

 the other. My variabilis material matches all of the Bassett 

 types which I have seen, but Bassett suggested in his original 

 description that he had two things. I define his variety as I 

 do, not only because of the types I have seen, but also because 

 the following points in the original description apply to this 

 rather than to the other variety: ''Head finely and evenly 

 punctate on the vertex**. Thorax * finely rugose radial 

 area faintly clouded on the second transverse vein in the 

 male Length: body male .10, female .11 inch." As an 

 appendix to this description he states that 'The description 

 of the female does not apply to all the specimens of this sex 

 reared from these galls, as in some the radial area has no 

 cloud, but a simple broadening of the veins bounding it", 

 which might be one way of stating that the cloud in the other 

 variety, sculpta, is as heavy as the veins. 



Diplolepis variabilis variety sculpta, new variety 



FEMALE. — Shows the following characters in addition to those 

 common to all varieties of the species: Head finely puncto-rugose, 

 much more rugose than in variety variabilis; mouthparts rufous, the 

 tips of the mandibles piceous; thorax coarsely, rugosely sculptured pos- 

 teriorly between the parapsidal grooves; parapsidal grooves wider, more 

 rugose than in variety variabilis; scutellum rather more rugose and 

 m.ore depressed anteriorly than in variabilis; abdomen bright rufous, 

 darker rufous posteriorly; legs a peculiar, rich brownish rufous, the 

 coxse darker basally; wing veins dark brown, heavier than in variabilis 

 or nifopicea; areolet rather large; cloud on veins of radial cell dark 

 brown, almost as heavy in places as the veins; length 2.7-3.5 mm., aver- 

 aging distinctly larger than in varmbilis. 



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

 Thorax more rugose, and the parapsidal grooves wider than in vari- 

 abilis; wing veins dark brown, decidedly heavier and more decidedly 

 clouded than in the male of variabilis; areolet rather large; length 2.5- 

 3.5 mm., averaging decidedly larger than the male of vai'iabilis. 



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

 rieties. 



RANGE.— Utah: Provo. 



TYPES.— 150 females, 150 males, 30 galls. Holotype female, para- 

 type adults, and galls at The American Museum of Natural History; 

 paratype adults and galls at Stanford University, the U.S. National 

 Museum, the Museum of Comparative Zoology, the Philadelphia Acad- 

 emy, and with the author. Labelled Provo, Utah; April 18, 1920; Kin- 

 sey collector.
