Remarks. — Holotype, allotype, and 146 paratypes were collected 

 and bred from twigs of Cowania mexicana at Williams, Ariz., by 

 Barber and Schwartz. Sixteen paratypes are from Colorado Springs 

 and Cheyenne Canyon, Colo., bred from Prunus americana or col- 

 lected on wild currant and apple by B. T. Harvey.

 "Length, 1.9 mm.; stout, black, with brown and gray scales; thei 

 front plano-concave, with a strong transversely arcuate impression 

 behind the epistoma, the middle line impressed, clothed with stout 

 pubescence, becoming long, dense and pale on the epistomal margin, 

 with a rather coarse granule behind the impression on each side the i 

 middle line ; the eyes long, narrow, extending upon the ventral surface. 



"The pronotum twice as wide as long; the sides very strongly j 

 rounded behind and very strongly constricted in front ; the front mar- 

 gin broadly emarginate at the middle; very densely subgranulately , 

 punctured, clothed with brown and grey, very stout pubescence, the 

 grey predominating on the sides and behind; the cephalic margin 

 unarmed or nearly so, somewhat elevated, with pale fine pubescence 

 and brown, elongate, elevated scales; with three pairs of elongate 

 recurved rugosities in a longitudinal row on the middle of each side 

 in front, the first pair on the front margin. 



"The elytra as wide as the pronotum, slightly less than one-half 

 longer than wide, the basal margin very strongly elevated, recurved 

 and coarsely serrate in the scutellar region; the sides subparallel on 

 the basal half, broadly rounded behind ; the striae distinctly, rather 

 strongly impressed, the strial punctures rather coarse, not close, deep 

 and distinct, bearing very minute setae ; the interspaces feebly convex, 

 minutely punctured, and with a median row of granules, bearing very 

 small, elongate scales which hardly cover the surface, and a median 

 row of longer, erect, very stout bristles ; the pubescence brown, with 

 numerous scattered white scales, more abundant toward the base and 

 forming a narrow band along the suture; the first two abdominal 

 sternites subequal in length, each longer than the next two united. 



"Salmon Arm, B. C. ; apple trees, in dying bark." 



The above is Swaine's original description quoted verbatim. No 

 specimen of the species has been seen by the writer.
