86 CASEY 



rounded and thence strongly converging and nearly straight to the 

 apex, the median sulcus wider, less acute at the bottom, the sublateral 

 impression much more feeble and more diffuse; elytra nearly similar 

 in form and sculpture but more densely and rugosely punctate through- 

 out, especially in the areolae, the apices narrowly but more obliquely 

 truncate, the sutural angle prominent and acute; male sexual charac- 

 ters similar; tarsi more metallic green in lustre. Length ( c?) 23.0 mm. ; 

 width 7.2 mm. Pennsylvania serriger n. sp. 



3 — Form oblong, depressed, dark bronze above, feebly shining and sparsely 

 pubescent in patches; head coarsely punctate, deeply, longitudinally 

 grooved; prothorax broader than long, the sides obtusely angulate med- 

 ially, oblique anteriorly, subparallel behind, feebly sinuate before the 

 hind angles, which are moderately prominent; apex feebly emarginate, 

 the base bisinuate; surface with a broad vague channel medially and a 

 moderately deep longitudinal impression sublaterally, coarsely rugulose 

 at the sides, smoother medially; elytra oblong, depressed, parallel, 

 gradually narrowed and moderately serrate at the sides in apical third, 

 the apex obtuse; surface with four vague nervures, the latter with 

 thickened spaces which surround large but very vague fovese [areola?], 

 the nervures feebly shining, the intervals opaque, rugulose, sparsely 

 punctured and with very short pubescence; under surface similar in 

 color to the upper, irregularly and coarsely punctate, with spots of denser 

 and finer punctuation. Length 27.5 mm. Texas. [= Chalcophora 

 fulleri Horn] fuller! Horn 



Form stout, very moderately convex and not very shining, with a pronounced 

 metallic green lustre above, each puncture with an extremely small 

 hair, which is more developed in the male; under surface cupreous and 

 polished along the middle, greenish and duller laterally, the punctures 

 fine and dense laterally, with numerous small smooth patches, the 

 pubescence extremely minute and inconspicuous ( 9 ) or longer, dense 

 and very distinct ( d^) ; head moderate, densely and coarsely punctato- 

 rugose, narrowly excavated along the median line, with a small deep 

 fovea nearly as in campestris; antenna; apparently longer in the female 

 than in the male but not attaining the thoracic base; eyes moderately 

 prominent; prothorax fully two-thirds wider than long, the sides par- 

 allel and evenly bisinuate to well before the middle, there obtusely 

 angulate and thence strongly convergent and straight to the apex; 

 base but feebly impressed at the scutellum; surface finely, sparsely 

 punctate medially, coarsely and rugosely laterally, the median sulcus very 

 broad, deeper and more densely punctulate anteriorly, becoming gradu- 

 ally obsolete basally, with the median line deeper just before the basal 

 margin, the large sublateral impression, just behind the middle, feeble 

 and indefinite; elytra about twice as long as wide, evidently wider than 

 the prothorax, parallel, the sides rapidly converging, arcuate and slightly 

 serrate in apical third, the apices cupreous, narrowly oblique, with the 

 sutural angle produced and acute; surface somewhat finely, closely 

 punctato-rugose throughout and similarly so and equally shining and 

 puberulent in and outside of the areola;, the nervures not as prominent
