New Jersey: Newfoundland, July; Masonville, May (Wenzel). 
Pennsylvania: Baoba, Pike Co., July (Wenzel). 
In some localities both the typical form and the variety occur 
together with intermediate specimens. In other localities, for instance 
at Old Forge and Saranac Lake, N. Y., numerous specimens collected 
there were all typical fulgens; moreover, the bright green or golden-green 
color apparently never occurs in typical suhtilis and I have for these 
reasons restored Leconte's fulgens as a variety of subttlis. 
DoNAciA TUBERCULiFRONS Schacffcr. 
Elongate, moderately depressed; color aeneous, cupreous or rarely 
dark metallic blue; antennae black, the first four or five joints more or 
less metallic; legs concolorous. 
Head densely punctate, punctures coarser and less numerous 
posteriorly; feebly constricted behind the eyes, which are moderately 
large and prominent; median line deeply impressed; posterior tubercles 
generally prominent; antennae reaching to about the middle of the 
elytra and as usual slightly shorter in the females, second and third 
joints short, equal or sub-equal. 
Prothorax about as wide at apex as long; sides scarcely converging 
behind; lateral tubercle more or less distinct; anterior angles distinct; 
anterior impression more or less distinct; posterior impression generally 
faint or absent; median impression generally deep, not extending to 
apex nor base ; surface usually sparsely and moderately coarsely punctate, 
much more densely anteriorly and strigate-rugose laterally. 
Elytra at about apical third less strongly depressed than usual; 
apices truncate, outer angle rounded; anterior impressions distinct; 
posterior impressions faint or absent; serial punctures moderate, finer 
towards apex; intervals transversely strigate, strigation generally sparse 
on the disk but dense at sides and apex, often coarser rugae are also 
present which extend transversely from interval to interval but they 
are rather sparse on the disk. 
Body below densely and finely punctate and rather densely pubescent 
with short white hairs, the last four ventral segments generally less 
densely punctate and rather more sparsely pubescent; pubescent space 
near anterior coxae rather small; intercoxal process variable in the two 
sexes; posterior femora armed below with a moderate tooth in both sexes. 
Length: 6.5-8 mm. 
Male: Posterior femora reaching to apex of third ventral segment 
or slightly below; intercoxal process less than one half the width of the
