flexed posteriorly at the humeri and continuing narrowly along the side-margin to 

 the middle, the large basal spot also connected by a short sutural isthmus with a 

 small rounded common sutural spot just behind the middle ; pubescence long, 

 coarse and bristling. Length 0.9-I.0 mm.; width 0.65-0. 75 mm. Bahamas 

 (Eleuthera and Egg Islands) — Mr. Wickham bahamictlS sp. nov. 



Oblong, much longer than wide, very pale luteo-flavate, the pronotum less pale than 

 the elytra but uniform throughout and without a median basal spot, much less 

 transverse than in bahamicus ; sides somewhat discontinuous, feebly convergent, 

 evenly and feebly arcuate, the punctures minute but visible and rather close-set ; 

 elytra evidently longer than wide, nearly straight at the sides, very obtuse at apex, 

 finely but strongly, somewhat closely punctate, the darker design piceous- black 

 and less abruptly defined than in bahamicus, consisting of a large subtriangular 

 common basal spot, somewhat prolonged in a fine acuminate line at each side of 

 the suture, but not united to the rounded common sutural spot at apical two-fifths ; 

 flanks infuscate at the middle and again at the external apical arcuation ; pubes- 

 cence rather short and inconspicuous. Length 1. 15 mm.; width 0.78 mm.

87 — Larger species, broadly oblong-oval, pale and uniform luteo-flavate throughout, the 

 abdomen piceous at the middle of the base ; pronotum finely punctulate, the sides 

 almost continuous but a little more arcuate, strongly convergent ; elytra a little 

 longer than wide, parallel, very obtusely but circularly rounded behind, finely 

 but strongly, rather closely punctate, the suture with a parallel nubilous piceous 

 vitta from the base to rather behind the middle ; pubescence coarse and moder- 

 ately short. Length 1.55 mm.; width 1.05 mm. Kansas. .. .dulcis, sp. nov. 



Smaller and more narrowly oval, the elytra not darker on the suture 88 



88 — Elytra about as long as wide, not narrowed behind except toward tip 89 



Elytra longer than wide, narrowed behind from near basal third ; prothorax well 

 developed, only moderately transverse, scarcely perceptibly punctulate, the sides 

 continuous with those of the elytra but rather more arcuate, moderately conver- 

 gent ; elytra rather narrowly subtruncate at tip, finely but distinctly and rather 

 closely punctate, the pubescence very short and subdecumbent. Length I.I-I.2 

 mm.; width 0.65-0.7 mm. Michigan and Illinois £eger, sp. nov. 



89 — Prothorax minutely punctulate, the sides continuous with those of the elytra, 

 rather strongly convergent and very feebly arcuate ; elytra finely and quite closely 

 punctate, the pubescence very short, abundant and subdecumbent. Length i.i- 

 1.3 mm.; width 0.75-0.8 mm. California (Alameda Co. ) debilis Lee. 



Prothorax relatively smaller and more convex, impunctate, the sides evidently discon- 

 tinuous, feebly convergent, evenly and rather strongly arcuate ; elytra distinctly 

 and somewhat abruptly wider than the prothorax, obtusely rounded or subtruncate 

 at tip, with somewhat coarse but very shallow and sparse punctures, the pubes- 

 cence longer, sparser and more erect than in debilis, but still quite short. Length 

 I.I mm. ; width 0.68 mm. Florida pusiOt sp. nov. 



Ill the subgenus Scymnobiiis the presternum is wholly devoid of 

 carinae, but there is frequently a fine short groove following the 

 margin of each acetabulum ; this is a very well-marked group of
