15 — Form rather short and broadly oval, the prothorax relatively small, with largely 

 developed pale diverging discal spots ; elytra wholly immaculate, the scu'iellum 

 alone dark. Length 4.7 mm.; width 2.8 mm. California (Monterey Co.)- 



politissima, sp. nov. 



16 — Three posterior spots of each elytron invariably isolated among themselves. 

 Length 4.6-6.4 mm.; width 2.7-4.4 mm. New Jersey to California (Sonoma 

 Co.), Texas (Brownsville) \_obsolefa Cr. ] convergens Gi^er. 



Three posterior spots much larger and coalescent ; humeral spot distinct, the two at 

 basal fourth equal and extremely minute, the two post-median very large and 

 slightly coalescent, the subapical also large and joined to the inner — not the outer 

 as usual — of the post-median spots by a short straight vitta parallel to the suture. 

 Length 5.2 mm.; width 3.2 mm. California (Sonoma Co. )..juncta, sp. nov. 



17 — Scutellar spot shorter and broad, abruptly terminating at or before basal third. .18 



Scutellar spot narrower and elongate 19 



18 — Elytra opaque, finely rugose and minutely punctate, each with a black vitta from 

 the callus abruptly ending in a bifurcation at three-fifths from the base, the inner 

 branch not truncate opposite the suture, also with a detached transversely triangu- 

 lar subapical spot; pronotum polished, minutely punctate. Length 5. 1 mm.; 

 width 3.0 mm. California (Lake Co. ) crotchi, sp. nov. 



Elytra more convex, nearly smooth, shining though feebly alutaceous and more dis- 

 tinctly, though not strongly, punctate ; elytra each with a very irregular continu- 

 ous vitta from the callus to apical sixth or seventh, the vitta strongly constricted 

 just behind the callus, then much dilated inwardly just behind the middle, this 

 part presenting a very broad rectilinearly truncate face opposite and close to the 

 suture, also slightly dilated externally at three-fifths from the base, thence curving 

 in almost regular arc, becoming transverse, and ending at a short distance from 

 the suture at a considerable distance from the apex, this apical part probably 

 being isolated in less fully developed specimens. Length 4.9 mm.; width 3.0 

 mm. Vancouver Island complex, sp. nov. 



19 — The scutellar spot extendmg to about basal third ; elytra more elongate and more 

 acutely rounded behind, the spots four in number, one at the callus, one larger 

 and anteriorly angulate slightly post-median, another, very small and more ex- 

 ternal, at three-fifths, and the fourth transverse, rather small, submedian, and at 

 apical fifth or sixth, the first and second of these doubtless frequently connected. 

 Length 5.6 mm.; width 3.2 mm. Colorado spuria Lee. 



The scutellar spot verj- elongate, extending to apical fourth or fifth, with a slight 

 rhomboidal enlargement near the base 20 



20 — Elytral .spots generally not greatly tending to confluence ; inner post-median some- 

 times uniting with the spot on the callus to fonu the usual broad vitta, the sub- 

 apical always isolated and distant from the apical angles ; lustre of the elytra 

 generally dull, but with the surface almost smooth, the punctures fine, but distinct 

 and rather close-set. Length 5.0 mm.; width 3.1 mm. New Mexico (Fort 

 Wingate) americana Cr. 



Elytral spots all confluent, forming a broad and nearly even straight vitta from the 

 callus to within a very short distance of the apical angles, slightly angulate ex- 

 ternally behind the middle, and thence moderately oblique nearly to the sutural 

 angle, the entire design nearly as in Paraiticniia vittigera ; lustre of the elytra
