NORTH AMERICAN COLEOPTERA. 2G3 



By its indistinctly punctate liead it resembles mnula, which has 

 no basal marginal row of punctures. C. parcepiindafa also closely 

 resembles it, but the head is entirely devoid of punctures, but it is 

 possible that future collections may make it necessary to unite them. 



Specimens have been seen from Pennsylvania, Maryland, North 

 Carolina, Florida and Arizona, and Garland, Colorado. 



13. C allitaeea Crotch. — Oval, rather robust, surface subopaque, olive-green 

 bronze, very distinctly alutaceous. Antennre with basal and five outer joints 

 piceous, the others pale. Head impuuctate. Thorax one-half wider than long, 

 very little narrowed iu front, sides arcuate, ba.se a little coarctate, basal mar- 

 ginal line distinct and entire, surface alutaceous, the punctures coarse, deep and 

 close at the sides, less so at middle. Elytra not wider at base than the thorax, 

 humeri obliquely rounded, umbone not prominent, but smooth ; striae distinctly 

 im]ires.sed, composed of coarse, deep and closely placed punctures, these, however, 

 wider, slightly convex, each with a row of very fine punctures. Body beneath 

 piceous, faintly bronzed. Presternum closely punctate, the side pieces entirely 

 smooth. Abdomen sparsely punctate. Legs entirely piceous. Length .06 — .08 

 inch. ; 1.5 — 2 mm. 



This species is one of the most readily known. Its quite opaque 

 surface, coarse sculpture and entirely piceous legs se])arate it very 

 easily from any other. In consetpience of the thorax being slightly 

 coarctate at base the marginal line of the body is not continuous 

 from the thorax to the elytra. ■ 



Occurs from northern Georgia to Florida. 



14. C'. sul>viri«lis Lee. — Oval, robust, surface shining, bright green bronze 

 or slightly bluish. Antennse with basal joints rufotestaceous, tipped with brown, 

 the outer seven joints piceous. Head finely alutaceous, a punctured fovea near 

 each eye. Thorax fully twice as wide as long, narrower at apex, sides feebly 

 arcuate, basal marginal line fine and entire, surface alutaceous. but not well 

 marked, the punctures coarse, deep and close, a smoother median line near the 

 base. Elytra not wider at base than the thorax, humeri obliquely rounded, um- 

 bone moderately prominent and smooth, strise finely impressed, the punctures 

 relatively free, not coarser than those of the thorax, closely placed, intervals 

 slightly convex, wider than the strise, distinctly punctulate, subbiseriately near 

 the base. Body beneath piceous, with slight blue or greenish tinge. Prosternuni 

 punctate, the side pieces smooth. Abdomen not coarsely, but rather closely 

 l)unctate, except at the middle of the last segment. Femora piceous, bronzed, 

 libifE brown at apex, pale at base, tarsi brown. Length .08 -.14 inch. ; 2—3.5 mm. 



This species is the largest at present known in our fiiuna, and by 

 that and the usuallv britrht t>rpeu surface may be readilv known.
