Elytra distinctly wider than pronotum, nearly twice as long as wide ; sides 

 slightly diverging from humeral angles to apical third, then arcuately converg- 

 ing to tips, which are conjointly broadly rounded ; lateral margins vaguely serrate ; 

 basal depressions small and moderately deep ; humeral depressions not distinct ; 

 disk moderately convex, slightly uneven; surface finely, irregularly punctate, 

 the punctures denser basally, more or less transversely rugose, sparsely, irregu- 

 larly clothed with long, erect, whitish hairs, the intervals obsoletely granulose. 

 Each elytron with three very vague foveae, one in front of middle and two near 

 apical third, but without distinct longitudinal costae. 



Abdomen beneath sparsely, coarsely punctate, sparsely clothed with long, 

 recumbent, whitish hairs, intervals obsoletely granulose ; last visible sternite 

 deeply, arcuately emarginate at apex, without a submarginal ridge, lateral 

 margins finely serrate ; eighth tergite deeply, arcuately emarginate at apex, 

 densely granulose, coarsely, sparsely punctate, but not longitudinally carinate. 

 Presternum densely, coarsely punctate, rather densely clothed with long, fine, 

 semierect, whitish hairs, with a broad, rather long, strongly declivous lobe in 

 front. Anterior femur with a short, obtusely triangular tooth, which is 

 slightly dentate on outer margin. Anterior tibia slightly arcuate, with a rounded 

 dilation near apex ; middle and posterior tibiae straight. 



Length 8 mm., width 3 mm. 



Redescribed from the male type, No. 43175, in the United States 

 National Museum. 



Female. — Differing from the male in having the intermediate segments of the 

 antenna less compact, the last visible sternite vaguely emarginate at apex, the 

 eighth tergite broadly subtruncate at apex, and the anterior tibia unarmed 

 near apex. 



Type locality. — Grand Mound, Wash.

Washington : Grand Mound, March to July, reared ; White Salmon, July 1930, 



reared (W. W. Baker). Easton (A. Koebele). Medical Lake, July 14, 1920

Swan, July 4, 1932 (S. E. Crumb). 



Hosts. — This species has been reared from cultivated strawberry 

 plants {Frag aria sp.) collected at Grand Mound and White Salmon, 

 Wash., by William W. Baker. It has also been recorded from crowns 

 of strawberry plants collected at Coeur d'Alene, Idaho, by H. T. Black. 



The specimens from the type locality are rather constant except in 

 size and in the lateral margins of the last visible abdominal sternite, 

 which are entire or distinctly serrate, but some examples from the 

 other localities vary from the typical form in having the foveae and 

 longitudinal costae on the elytra vaguely indicated, the lateral margins 

 of the last visible abdominal sternite scarcely interrupted, the tips of 

 the elytra separately rounded, the pronotum with a weak median de- 

 pression and the sides regularly rounded, and the head with a vague 

 chevron on the vertex and two vague, smooth spots on the front. 

 The specimens from Idaho have the clypeus more shallowly emargi- 

 nate in front, the eighth tergite of the male slightly emarginate, and 

 the dilation on the anterior tibia of the male more elongate. The 

 specimens from White Swan, Wash., are similar to the ones from 

 Idaho, but are larger, subopaque, and more finely punctured. The 

 length is from 6.4 to 9 mm.
