Formosa Say. Red cupreous, shining margins, beneath metallic 
blue; head granulate rugose, hairy; thorax broader than long, granu- 
late; the humeral lunule, the middle fascia and the apical lunule broad, 
connected at margin, the middle band is usually only obtusely bent, 
not much deflexed, but it varies in shape. Occurs in Kans,, Tex., 
Col. Length 17—18 mm. 
Var. generosa Dej. Brown neous opaque, beneath green. Resembles 
in every respect formosa, but in this species the middle band is usually 
rectangularly bent. In some specimens the tip of the humeral lunule 
nearly reaches the angulation of the middle band. Occurs in N. Y., 
N.J., Penn., Mo., Ky., Col Length 16.5—18 mm 
Var. venusta Lec. Cupreous opaque, beneath bluish-green shining. 
Differs only by being more slender and convex. Occurs in New Mex. 
Kans., Nebr., Dac. Length 13—15 mm.

Latesignata. Brownish black, beneath green, head granulate 
rugose, hairy; labrum short, three-toothed; broader than long, scarcely 
narrowed behind, little convex, sides hairy; elytra strongly punctured, 
humeral lunule obliquely prolonged, middle band rectangularly bent, 
expanded at margin, connected with humeral lunule, apical lunule 
anteriorly inflected. Many specimens have the markings, very broad 
confluent. Less convex and the elytra more strongly punctured than 
generosa, Occurs in California (San Diego). Length 23 mm. 
Leconte, Ann. Lyc. 1852, V, 172, 
Willistoni Lec. Bronzed brown, beneath metallic green or blue: head 
rugose, smooth; labrum with acute tooth at middle; thorax rugose, 
hairy at the sides, scarcely narrowed behind, elytra strongly punctured 
with a broad lobed white margin and refracted wide band, the descend- 
ing portion of which is long and hooked very near to the terminal 
lunule; humeral lunule not at all oblique, bead of side margin dark 
metallic. Some specimens have bluish or green reflections in the im- 
pressions of the thorax. It seems to bea variety of /wlezda but its 
surface is less smooth and shining and it differs also by the pattern of 
the markings, and is also somewhat broader and less convex. Occurs 
in Wyoming on alkaline mud. JLength 10,5—1r4 mm.
