 8 — Body large, elongate-oval, black, the elytra with irregular anastomosing bands of 

 testaceous nearly as in the preceding, the pale vestiture of the rufous areas rather 

 long and fulvous, that of the black areas short, dark and inconspicuous ; pron-

9 — Epipleune of the elytra flat ; body stout, Mack, the elytra variegated with paler 



areas which are clothed with paler pubescence, nearly as in the preceding species ; 



pronotum in the female not quite twice as wide as long, rather strongly but 



sparsely and evenly punctured throughout, the sides moderately convergent. 



Length 2.7 mm.; width 1.6 mm. Texas. \..% complex, sp. nov. 



Epipleurae deeply concave ; body in coloration and sculpture nearly as in complex, 

 the pale areas of the elytra larger and more suffused and the variegated vestiture 

 shorter ; pronotum in the female much more transverse, more than twice as wide 

 as long, the sides very strongly converging from base to apex ; Lgs pale, the 

 femora black. Length 3.2 mm.; width 1.78 mm. California (Shasta Co.)

11 — Body black, the elytra with broken transverse pa'er bands clothed with the- 

 usual paler pubescence, thesutural portions of the submedian band far in advance 

 of, and detached from, the lateral portion ; prothorax of the male with the 

 median lobe of the base rather broadly rounded, the sides evenly convergent and 

 broad'y, almost evenly arcuate from base to apex. Length 2.4 mm.; width 1.2 



mm. California sternalis Jayne 



Body as in the preceding, the submedian band of the elytra finer, almost continuous, 

 the sutural crossing but little more advanced than the lateral part ; basal lobe of 

 the prothorax smaller, more narrowly rounded and more abruptly formed, the 

 sides strongly rounded basally, becoming thence much more strongly convergent 

 and almost straight to the apex in the male, the base somewhat wider than the 

 base of the elytra ; size very small. Length 1.8 mm.; width 1.0 mm. Cali-

• 12 — Body black, with variegated white and fulvous bands nearly as in sternalis, the 

 sutural part of the submedian band far in advance of the lateral angulation and de- 

 tached from it; prothorax at base equal in width to the elytra, very strongly trans- 

 verse, in the male distinctly more than twice as wide as long, the sides very
