are rufotestaceous. T\w tliorax has a slight intimation of an oblique 

 truncation in front, but there is no post-apical angulation. C. wneola 

 Lee. does not differ specifically from pulicaria. 



Specimens have been seen from Pennsylvania, Maryland, North 

 Carolina, Texas and Colorado. 



20. C creiiulata Crotch. — Form oval, convex, robust, the thoracic and 

 elytral margins almo.st exactly continuous, piceous. faintly bronzed, shining. 

 AnteniuB rufotestaceous Head extremely finely alutaceous, impunctate. Thorax 

 twice as wide at base as long, distinctly narrowed in front, sides feebly arcuate, 

 the basal marginal line distinct, defined by a row of closely placed, fine punc- 

 tures, the disc very distinctly alutaceous, the punctures coarse, deep, sparsely 

 and rather irregularly placed. Elytra not wider than the thorax at base, humeri 

 smooth, not prominent, strije scarcely impressed, the punctures large, deep and 

 moderately closely placed, intervals wider than the strise, shining, slightly con- 

 vex, very indistinctly uniseriately punctulate. Body beneath piceous black, 

 faintly bronzed. Prosternum smooth, the side pieces smooth. Abdomen not 

 distinctly punctate, except at the sides of the last segment. Femora piceous, 

 bronzed, tibije and tarsi rufotestaceous. Length .06--. 08 inch. ; 1.5 — 2 mm. 



This species is noteworthy in having the coarse punctures of the 

 thorax rather unequally placed, and the prosternum smooth. 

 Occurs in North Carolina, Georgia and Florida. 



21. C coiiliiiis Crotch. — Rather broadly oval and of robust facies, piceous, 

 slightly aeneous. Antennae rufotestaceous. Head faintly alutaceous, impunctate. 

 Thorax twice as wide as long, distinctly narrowed in front, anterior angles ob- 

 liquely truncate, a distinct post-apical angulation, behind which the sides are 

 feebly arcuate, disc distinctly alutaceous, without basal marginal line, the punc- 

 tures of moderate size, closely, but not densely placed, not deeply impressed. 

 Elytra scarcely wider at base than the thorax, humeri rounded, umbone moderate, 

 the striiB impressed on the disc, more deeply at the sides, the punctures relatively 

 coarse, clo.se and deep, but not serrate, intervals slightly convex, wider than the 

 striae on the disc, but not at sides, surface smooth, shining, with fine interstrial 

 punctures. Body beneath piceous black, shining. Prosternum punctate, side 

 pieces smooth. Abdomen sparsely indistinctly punctate. Anterior and middle 

 legs and posterior tibiae and tarsi rufottstaceous, posterior femora piceous. 

 Length .06 inch. ; 1.5 mm., a little larger and smaller. 



This species varies a little in form and somewhat in the distinct- 

 ness of the thoracic punctures. 



After an examination oi' Jiavicornis I can find no reason to separate 

 it from the present species. The basal puncture, of which Dr. Le- 

 Conte wrote, is an optical deception, caused by a slight impression 

 close to and along the basal margin, which looks punctiform when 

 seen from above. 



Occurs from Pennsylvania to Florida, Michigan, Colorado, Dakota 

 and California (Mendocino).
