apically, the smooth line distinct but not quite entire; elytra parallel, 

 with straight sides, rounding at apex, about as wide as the prothorax and 

 slightly more than twice as long, about one-half longer than wide; striae 

 narrow, the intervals fully four times as wide, with fine and loosely 

 confused punctures. Length (cf ) 2.4 mm.; width 0.85 mm. Louisiana. 

 One example. 



This species also belongs to the curticollis section, but is much 

 smaller and with less abbreviated prothorax, apparently somewhat 

 wider before the middle than at base, in its more parallel, more 

 obtusely rounded and more finely striate elytra and in general 

 appearance. 



Barilepton Lee. 



The following species is allied somewhat to quadricoUis, but differs 



in the shorter and relatively stouter beak, larger prothorax and 



more scanty vestiture: 



Barilepton productum n. sp. — ^Elongate, parallel, strongly convex and 

 cylindric, moderately shining, deep black, with obscurely rufous legs; 

 squamules above whitish, fine and sparse on the pronotum but closer 

 though not dense along the sides, coarser and forming single or partially 

 double interstitial lines, and more broadly condensed at the base of the 

 second interval and on the third posteriorly; beneath sparse but distinct, 

 white, dense on the met-episterna and close but not very dense almost 

 throughout the last three ventral segments; beak in the male thick, 

 cylindric, finely, sparsely punctate and shining, very strongly arcuate 

 basally, less so apically and distinctly shorter than the prothorax, the 

 antennae slightly beyond the middle; prothorax about as long as wide, 

 the parallel sides feebly arcuate, rounding and oblique in apical two- 

 fifths, the subtubulate apex three-fifths as wide as the base; punctures 

 somewhat small, moderately and unevenly separated, the smooth line 

 distinct but extending only slightly beyond the middle; scutellum tumid, 

 nude; elytra exactly as wide as the prothorax and more than twice as 

 long, with straight, parallel sides, gradually parabolic behind the middle, 

 not quite twice as long as wide; grooves fine but deep, the intervals 

 with uneven series of small and feeble punctures; male abdomen nar- 

 rowly impressed medio-basally and more broadly and feebly at the 

 middle of the last segment. Length (cf) 3.3 mm.; width i.o mm. 

 Louisiana (southern). One example. 



The rather common eastern species, named quadricoUis by 



LeConte, is very densely clothed above, thus having a widely 



different appearance from productum. 



Zagl3rptus Lee. 

 In this genus, which includes the most minute of the Barinac, 

 the body is rather abbreviated and very convex, with sparse coarse
