similarly distributed on the pronotum, but, on the elytra, they are 

 not uniformly well separated as in lucifer, but dense on the second 

 interval, and with the intervals alternating more noticeably in 

 abundance of the scales; beak in the male a little shorter and 

 thicker, more strongly sculptured and only about as long as the head 

 and prothorax, the antennae similarly inserted; prothorax somewhat 

 larger, nearly one-half wider than long, the sides more strongly 

 rounding anteriorly; apex more than half as wide as the base, the 

 basal lobe smaller; punctures similarly strong and dense; scutellum 

 with very few more slender and sparse, almost hair-like squamules; 

 elytra almost similar in form but broader, only a little wider than the 

 prothorax and twice as long, the striae rather coarser, the intervals 

 more alternating in width; male with nearly similar abdominal and 

 prosternal characters, the usual spines wanting. Length (cf ) 2.0 

 mm.; width 0,9 mm. Mexico (Teapa, in Tabasco). One example, 

 received from Mr. Champion *tabascanus n. sp. 



Color obscure rufous throughout; form somewhat narrowly subrhomboid- 

 oval, convex, rather shining, the squamules of the upper surface 

 slender but very distinct, slightly yellowish on the pronotum and 

 narrowly denser along the median line basally, pure white on the 

 elytra and arranged, without denser regions, in one or two series 

 on the strial intervals, whitish but rather sparse and linear on the 

 under surface; beak in the male slender, evenly arcuate, bright 

 rufous, a little less than half as long as the body, the antennae inserted 

 just visibly behind the middle, slender; prothorax a fourth wider 

 than long, the sides feebly converging and nearly straight, rather 

 abruptly rounding near apical third to the constricted apex, which 

 is much more than half as wide as the base, the basal lobe small, 

 abruptly subtriangular; punctures deep, relatively coarse and very 

 dense; scutellum small, parallel, with three or four very minute 

 hair-like squamules; elytra two-fifths longer than wide, a little 

 wider than the prothorax and twice as long; sides oblique and 

 evenly, somewhat strongly arcuate throughout, the apex narrowly 

 rounded; striae moderate; intervals twice as wide as the striae or a 

 little less, somewhat finely and sparsely punctate; male with the 

 abdomen narrowly subimpressed or flattened and more sparsely 

 clothed with more slender squamules medio-basally, the prosternum 

 not at all armed. Length (cf ) 1.78 mm.; width 0.75 mm. Missis- 

 sippi (Vicksburg) scutellinus n. sp. 



9 — Form rhomboid-oval, convex, piceous, the legs and beak rufous; 

 squamules above linear, pale yellowish and lustrous, replaced at 

 each side of the dense medial line of the pronotum — broadly basally, 

 narrowly toward apex — by smaller and more slender dark squamules, 

 on the elytra larger, elongate and conspicuous, widely spaced in 

 single lines on some of the intervals, but, on the second, denser in 

 uneven double line basally and in dense single line apically, on the 

 fourth dense except basally and apically, and, on the sixth, dense 

 basally; beak in the female strongly, evenly arcuate, rather short, 

 barely longer than the head and prothorax, distinctly tapering from 

 base to apex, the antennae inserted barely at all behind the middle;
