somewhat from the basal margin internally, the subapical spot oval, adjoining the 

 limb and distant nearly half its width from the suture. Length 2.4 mm.; width 

 1.8 mm. Florida querceti Schz. 



II — Narrowly oval, finely, not closely punctulate, with flavate pale areas ; male with 

 the head pale, the pronotum black, with a very narrow pale apical margin per- 

 fectly even in width but gradually wider from the eyes and extending to the basal 

 angles, the black area with a feeble angular extension at apical third ; scutellum 

 black ; elytra pale, the suture more or less broadly black from a short distance be- 

 hind the scutellum, narrowest just behind the middle, extending at apex ante- 

 riorly along the sides very narrowly to about apical third, also with a triangular 

 black spot involving the callus and another, rounded but posteriorly sinuate, be- 

 hind apical third at outer third of the width ; under surface black throughout. 

 Length 3. 2 mm. ; width 2. 2 mm. Kansas albif rons Say 



Narrowly oval, with flavate pale areas anteriorly, reddish on the elytra, finely, not 

 closely punctulate ; male with the head pale, the pronotum black in a basal area 

 between the basal angles, the anterior margin of which curves evenly from the 

 basal angles to anterior third at lateral two-fifths, then feebly sinuate and then 

 extending forward in two rounded lobes separated by a narrow deep fissure 

 to apical fifth or sixth ; scutellum black ; elytra pale, the suture more or less 

 broadly black from the scutellum to the apex, narrowly at the scutellum and for a 

 short distance just behind the middle, the external marginal bead also black, be- 

 coming broader at the apex and joining the sutural black area ; anterior black 

 spot obliquely oval, sending off a nubilous connecting isthmus to the sutural 

 black area, the posterior spot smaller, at apical and outer third ; under surface 

 black throughout, the posterior femora in great part black, the intermediate less 

 so. Length 3.7 mm.; width 2.4 mm. California (Sta. Monica).

12 — Elytra each with two transversely confluent pale spots before the middle and a 

 subapical spot 13 



Elytra each with three small, widely isolated pale spots 15 



13 — The confluent pale spots very nearly separated ; male with a pale oblique humeral 

 spot which is absent in the female ; head pale in the male, the pronotum pale, with 

 a large and abruptly defined median black area from the base to apical fifth or 

 sixth, deeply emarginate at each side; female with the head pale, sometimes nar- 

 rowly darker at the edges, the pronotum similarly colored, the margins of the 

 black area less sharply defined as usual and extending nearly to the apical margin. 

 Length 2.9-3.7 mm.; width 2.I-2.8 mm. Texas (Brownsville) — Mr. Wick- 

 ham decora, sp. nov. 



The spots very broadly confluent, forming a fascia slightly emarginate on both sides. 14 

 14 — The fascia a third as wide as the length of the elytra, broadening within, broadly 

 truncate opposite the suture ; subapical spot very large, extending along the 

 limb, the marginal bead black ; head in the female pale throughout, the pro- 

 notum very broadly and intero-angulately pale at the sides. Length 5 2 mm.; 



width 3.6 mm. Kansas socialis, sp. nov. 



The fascia not more than a fourth or fifth as wide as the length of the elytra, the sexes 

 perfectly similar throughout in coloration ; head black, with a very large pale
