STUDIES IN THE AMERICAN BUPRESTID.9E 107 



next two combined. Length 14. 8-15. 7 mm.; width 5.2-6.0 mm. 

 Dakota, Wisconsin (Bayfield) and Indiana fulgens n. sp. 



Sides of the prothorax evenly converging and distinctly arcuate from a short 

 and very feeble though abrupt basal swelling to the apex, not evidently 

 incurvate at base; subapical spot of the elytra very much more oblique. 

 Body more elongate in form, brilliant and pure green in color, becom- 

 ing subaeneous beneath, maculate nearly as in fulgens but with the post- 

 median fascia generally fuller and less irregular; head strongly and 

 closely but somewhat irregularly punctate, the eyes moderately promi- 

 nent; antennae piceous-black, with feeble metallic reflection; prothorax 

 almost twice as wide as long to evidently less, more or less feebly im- 

 pressed along the median line, strongly and subequally but not very 

 closely punctate throughout, with a small and feeble sublateral impres- 

 sion at basal third; scutellum rather small, subquadrate but variable as 

 usual; elytra slightly more than twice as long as wide, evidently wider 

 than the prothorax, parallel, the sides gradually rounding and con- 

 verging in apical third, the apices, strife and punctuation nearly as in 

 fulgens; a small ante-median spot sometimes present but frequently 

 wholly obsolete; all the spots, as in fulgens, surrounded by a black 

 clouded border; abdomen punctulate nearly as in ftdgens, the lateral 

 punctures similarly larger and rather dense, only slightly more asperu- 

 late. Length 14. 2-17. 5 mm.; width 5.2-6.4 mm. Pennsylvania, New 

 York and Ontario (Sudbury). [= sextnaculata Hbst., a.nd Ihermin- 

 ieri Chev fasciata Fabr. 



A — Similar but more elongate, bright cupreo-aeneous above and below, 

 with feeble greenish reflection at the sides of the elytra, the latter 

 similarly maculate and sculptured; head nearly similarly sculptured; 

 prothorax less transverse, three-fourths wider than long, equally 

 strongly but much more densely punctured throughout, feebly im- 

 pressed medially toward base; elytra nearly two and one-half times 

 as long as wide the sides more gradually rounding and converging 

 behind and less oblique than \n fasciata, the apices similar; abdomen 

 similarly punctulate, the first segment more strongly impressed along 

 the middle though indefinitely as m fasciata. Length 16.2 mm.; 

 width 5.7 mm. Michigan fortunata n. subsp. 



34 — Elytra each with three large and distinct pale spots, one near basal 

 third and sometimes extending to the base, another behind the middle 

 and the third near the apex, the apices always sinuate and acutely 

 bidentate, the pronotum more or less evidently impressed along the 

 middle 35 



Elytra immaculate or having sporadically a small spot near three-fifths and 

 another still smaller near the apex . . .• 39 



35 — Anterior pale spot extending obliquely to the base and enveloping the 

 humeral callus. Body elongate, brassy-green; head purplish, punctate, 

 the front carinate; prothorax one-half wider than long, punctured, the 

 sides subparallel, the base bisinuate; elytra purplish, the basal pale 

 spot including a dark spot on the humeral callus, the spot at about one-
