I20 CASEY 



black; prothorax four- fifths wider than long, the sides feebly converg- 

 ing and straight to about the middle, there gradually rounding and more 

 convergent to the apex, the latter but feebly sinuate ; surface very coarsely 

 punctured, sparsely so medially and sublaterally, more densely and 

 confluently broadly near lateral fourth and near the sides, the median 

 line distinctly impressed and finely, densely punctate; scutellum small, 

 oblong; elytra not evidently wider than the prothorax, less than twice 

 as long as wide, parallel, obliquely subrectiHnear at the sides in fully 

 apical third, the apices broadly rounded, the sutural angles almost 

 obtuse; sculpture as in lauta though somewhat coarser; under surface 

 sparsely pubescent, finely, not closely punctate, the presternum broadly 

 concave, strongly, sparsely punctate, not more pubescent, the concavity 

 anterior becoming obsolescent posteriorly; apices of the ventral seg- 

 ments cupreous-red throughout the width. Length 20. 8 mm.; width 

 8.0 mm. Mexico (Chihuahua), — C. H. T. Townsend. . *fabulosa n. sp. 



Under surface bright cupreous throughout 8 



Under surface pale green, sometimes with faintly senescent reflection toward 

 the median line, or bright bronze throughout 10 



8 — Sides of the elytra posteriorly evenly rounding and converging to the 

 apices. Body elongate-suboval, the elytra frequently feebly inflated 

 subposteriorly, moderately convex, bright pale green to golden-green, 

 sometimes darker greenish-blue, the anterior parts with more or less 

 cupreous lustre, the elytral suture and side-margins bright-cupreous; 

 head densely, confluently punctate, with a more depressed and more 

 finely and densely punctured central spot which is longitudinally divided 

 by a raised median line, subglabrous (9), or very much more finely 

 and densely punctate throughout and conspicuously pubescent (d^); 

 eyes larger and more prominent in the latter; prothorax nearly twice 

 as wide as long, the sides nearly parallel as a rule to about the middle, 

 there rounding and more converging to the apex, sometimes converging 

 throughout; surface well impressed along the middle, moderately and 

 not closely or confluently punctate medially, irregularly, densely so 

 laterally; elytra three-fourths longer than wide, evidently wider than 

 the prothorax, the apices broadly rounded, the sutural angle frequently 

 minutely dentate; surface with the four discal ribs well developed, the 

 intervales evenly and densely cribrate; under surface rather finely but 

 strongly, not closely punctate, sparsely and feebly pubescent (9), or 

 conspicuously so {d), the abdomen more closely punctured in the lat- 

 ter; presternum more or less narrowly and distinctly impressed and 

 punctured along the median line. Length 14. 0-18.0 mm.; width 5.6- 

 7.3 mm. Oregon to British Columbia and Vancouver Island. [=Ancy- 

 locheira lauta Lee] lauta Lee. 



A — Similar to lauta in coloration and sculpture but smaller and narrower 

 in form, the prothorax but little narrower than the elytra, the sides 

 almost evenly converging and arcuate from base to apex; elytra and 

 under surface as in lauta, except that the apices in the former are 

 narrowly truncate; head in the male similarly densely ])unctured
