228 GEO. H. HORN, M. D. 



The last ventral of male is sinuate each side, the middle lobe 

 sliort, semi-circular, the margin reflexed ; surface flat, with a short, 

 deep, longitudinal impression near apex. 



This species closely resembles foliacea, but has the elytra a little 

 more distinctly punctate. The male characters aflbrd the only sure 

 means of separating them. 



Occurs in Missouri, Kansas, Colorado and California. 



17. H. laziilina Lee. — Elongate oval, feebly convex, bright blue or bluish 

 green, sliiniug. Antennae a little longer than half the body, piceous, bluish at 

 base, third and fourth joints equal. Head smooth posteriorly, a few coarse puncv 

 tures near the eyes, a transverse impression above the tubercles, which are small, 

 the carina obtuse. Thorax one half longer than wide, narrower in front, sides 

 arcuate, margin narrow, distinctly thicker at apex, disc convex, ante-basal im- 

 pression fine, feebly impressed, evanescent at the sides, surface alutaceous, dis- 

 tinctly and moderately closely puuctulate, an oblique series of coarse punctures 

 near the front angles. Elytra scarcely wider at base than the thorax, humeri 

 rounded, umbone not di.stinct, surface sparsely finely punctate, smoother at apex. 

 Body beneath as above; abdomen with few punctures. Length .14— .18 inch.; 

 .3.5-4.5 mm. 



Last ventral of male sinuate each side, median lobe not prominent, 

 flat, smooth at middle, an extremely short and shallow impression 

 near apex. 



Closely resembling tlncta, but less distinctly punctured and with 

 different male characters ; punctipenuis and foliacea are less punctate. 



Occurs in Colorado, Montana and Washington Territory. 



18. H. foliacea Lee. — Elongate oval, feebly convex, color variable from 

 bright green to dark blue, shining. Anteunje half as long as the body, slender, 

 piceous, greenish near base, joints three and four equal. Head smooth behind, 

 a group of coarse punctures near the eyes, a feeble transverse impreshiou above 

 the small tubercles, frontal carina obtuse. Thorax more than half wider than 

 Ions?, narrowed in front, the sides feebly arcuate, margin narrow, very slightly 

 thickened at the front angles, disc convex, the ante-basal line almost entirely 

 obliterated, surface alutaceous, distinctly, sparsely puuctulate, a little more 

 coarsely near the front angles. Elytra a little wider at base than the thorax, 

 humeri rounded, umbone not prominent, surface alutaceous, sparsely indistinctly 

 punctate, with a finely scabrous aspect. Body beneath as above; abdomen 

 coarsely, not closely punctate. Length .14— .18 inch. ; 3.5 — 4.5 mm. 



The last ventral of male is slightly sinuate each side, the middle 

 lobe short, the apical margin reflexed, a slight longitudinal impres- 

 !?ion near the apex which is often replaced by a smooth ?i)ace. 



The sexual characters are not very unlike those of lazulina, but 

 that has the entire surface more distinctly punctate. Injures the 

 grai)e vine.
