AMERICAN COLEOPTERA. 201 



separated on the front in the male by only about one-third more than their ver- 

 tical diameter; antenna a trifle more acutely serrate; anterior raised margin of 

 metasternum distinctly angulate at middle. Length 3.5-6 mm. 



This species has been found only in the southern portions of our 

 territory, occurring from Florida (Haw Creek) to Louisiana (Cov- 

 ington) and Texas (Columbus and Brownsville). 



The above measurements are the extremes in the series of nine 

 specimens before me. LeConte's type from Louisiana (in the Ulke 

 collection) is a little larger than the largest of these, but seems to 

 be identical. As stated by LeConte the head is a little more evi- 

 dently impressed beneath than in peltatus. 



4. X. peltatus Harris. — Brown, or reddish brown, elongate-oblong, pubes- 

 cence fine, sericeous, pale fulvous, moderately plentiful but not concealing the 

 surface color. Terminal joints of both maxillary and labial palpi elongate, fully 

 twice as long as wide, very little dilated apically, the apex strongly oblique and 

 pointed, the inner angle broadly rounded. Antennae moderately serrate, joints 

 3-10 triaugular, the third and outer joints a little elongate, the intermediate ones 

 about as wide as long, terminal joint elongate-oval or subfusiform. Eyes large 

 and convex, the width of the front much less than twice their vertical diameter 

 in the male, and a little greater than twice their vertical diameter in the female. 

 Head finely rather densely punctate, feebly obtusely carinate at middle. Pro- 

 thorax transverse, moderately narrowed in front, disk convex, broadly impressed 

 each side before the basal margin, leaving the median line more convex ; side 

 margin very narrow, not reflexed ; surface rather dull, finely sparsely punctate, 

 the interspaces densely minutely punctulate. Elytra finely closely punctate and 

 with fine lightly impressed strise which are finely not closely punctate. Beneath 

 densely finely punctured and pubescent; anterior raised marginal line of meta- 

 sternum broadly arcuate at middle. Length 3.4-5 mm. 



Occurs throughout the eastern United States from Canada to 

 Texas. The following localities are represented in the material 

 studied. Massachusetts, New York, Pennsylvania, Maryland, Dis- 

 trict of Columbia, Virginia, North Carolina, Georgia, Canada, Ohio, 

 Kentucky, Illinois, Louisiana, Texas. 



5. X. harrisii n. sp. — There is nothing of moment to add to the characters 

 given in the table for the separation of this species from peltatus. The two have 

 hitherto been confused in collections, though abundantly distinct. It is quite 

 impossible to determine with certainty to which the name peltatus was originally 

 given, but I have used it for the species now bearing this label in the LeConte 

 collection. Length 3.7-5.5 mm. 



Harrisii is less widely distributed than peltatus, being more ex- 

 clusively northern in range. The following localities are known to 

 me : New Hampshire, Massachusetts, New York, New Jersey, 

 Pennsylvania, Kentucky, Ohio, Michigan, Canada.
