50 REVISION OF THE CICINDEL@ OF THE UNITED STATES. 
ther of which characters is found in C. cuprascens or macra. The white markings 
are of the same form as in the preceding, but wider, so that the elytra appear white, with 
the suture as far as the middle and four branches dark-coloured: the first and second 
branches are oblique forwards and hooked, the third is small, straight and oblique 
backwards, while the fourth is oblique forwards, thickened at each end, and angulated near 
the suture. 
39. ©. macra, valde elongata, cylindrica fusco-2enea, capite thoraceque albo-pubescentibus, hoc latitudine fere 
longiore lateribus vix rotundatis, elytris confertim punctatis, ad apicem oblique angustatis serrulatis, macula basali, 
margine lobato, ramo subhumerali obliquo hamato, fascia media tortuosa fimbriata lunulaque apicali utrinque in- 
flexa albis; subtus viridi-eenea, dense albo-pubescens, medio glabra, trochanteribus rufis, pedibus longissimis; pal- 
pis sexus utriusque pallidis ad apicem zeneis, labro brevi unidentato. Long. -48—-53. 
Mas elytris subsinuatim oblique angustatis, sutura prominula. 
Femina elytris magis sinuatim oblique angustatis, angulo externo obtuso haud rotundato, sutura haud promi- 
nula.

Wisconsin and Minnesota. More slender than C. cuprascens, and readily known 
by the elytra being more than twice as long as wide, less strongly punctured and not 
shining: the markings are of the same form, but narrower, and the external angle of the 
obliquely sinuate elytra of the female is obtuse, or at most rectangular. 
40. C. sperata, elongata cylindrica, supra fusco-cuprascens haud nitida, capite thoraceque albopubescentibus, hoe 
latitudine fere longiore, lateribus parum rotundatis, elytris confertim punctatis, ad apicem oblique angustatis ser- 
rulatis, spina suturali prominula, margine, ramo subhumerali obliquo hamato, fascia elongata subtortuosa seepe fim- 
briata, lunulaque apicali utrinque inflexa albis; subtus viridi-znea, dense albo-pubescens medio glabra, pleuris cu- 
preis; pedibus longissimis trochanteribus rufis; palpis et labro ut in prioribus. Long. -46—5. 
Mas elytris oblique vix sinuatim angustatis: thorace postice haud ampliato. 
Femina elytris sinuatim oblique angustatis, angulo externo obtuso haud rotundato; thorace postice perparum

Rio Grande, at various places: collected by Messrs. Schott and Clark of the United 
States and Mexican Boundary Commission. Slightly more elongated than C. cuprascens, 
and easily distinguished from that as from the other species of this group by the absence 
of a basal white spot on the elytra. I incorrectly mentioned (Proc. Acad. 6, 439,) this 
species as C. curvata Chevr.; in that species, however, the humeral branch is prolonged 
backwards parallel with the suture, and is not hamate, 
One female specimen varies in having the lateral white margin of the elytra broader, so 
that the lobes of the apical lunule become wider and rounded. 
GROUP XIII. 
A small species with large prominent eyes, densely pubescent head and thorax, and 
pale legs: the elytra are flat, broad and white, with a few sinuous dark lines, the tip is
