BADISTER Clairv. 



The species of Badister known in our fauna may be tabulated 

 as follows : 



Elytral striae fine, interspaces broad and flat 2. 



Elytral strise deep, interspaces narrow, convex; antennae and legs rufo- 



testaeeous, elytra rufo-piceous, clouded behind 1. iiotatus. 



2. — Elytra spotted 3. 



Elytra not spotted 5. 



3. — Prothorax black, legs and elytra orange, the latter behind tlie middle 



mostly black 4. 



Prothorax legs and elytra bright yellow; the latter with broad medial 

 band interrupted at the suture, and an apical blotch iridescent black; 



basal impressions of prothorax shallow, but broad 2. pulcheilus. 



Prothorax legs and elytra bright yellow; the latter with the black mark- 

 ings confluent longitudinally from the fourth to the eighth stria, basal 

 impressions of prothorax shallow and small; (differs from the European 

 specimens only by the prothorax very slightly more flattened near the 

 hind angles, and by the spots being more broadly confluent). 



3. bipustiilatns. 



4. — Side margin of prothorax a little wider and more reflexed near the base; 



broad elytral medial band and apical spot confluent longitudinally from 



the fourth to the sixth stria 4. inaCHla.tus. 



Side margin of prothorax not wider near the base; elytral spots con- 

 fluent from the fourth to the ninth stria, forming the pattern described 



below 5. elegaiis u. sp. 



5.— Black, or nearly so, legs yellow 6. 



Prothorax and legs testaceous, elytra piceous, suture, side margin, epipleurae 

 and base testaceous; hind angles of prothorax broadly rounded, side 



margin fine, scarcely broader near the base 6. obttisus. 



Piceous; head as wide as prothorax; hind angles of prothorax obtuse, 

 slightly rounded, base obliquely truncate each side, side margin slightlv 



wider and more reflexed near the base 7. ferrugiueus. 



Entirely black; head narrower than prothorax, which is formed as in 



ferrugineus but less narrowed behind 8. antliracintis. 



6. — Hind angles of prothorax very much rounded 9. flavipes. 



Hind angles of prothorax obtuse, feebly rounded; side margin narrow, not 



more reflexed towards the base; margins piceous 10. Illicans. 



Hind angles of prothorax obtuse, not rounded; side margin wider and 

 more reflexed near the base; margins piceous 11. reflexiis n. sp. 



3. B. bipiistulatus Fah-. 



I have two specimens from Vancouver Island, which agree per- 

 fectly with a European specimen, except in having the prothorax a 

 little flatter at base near the angles, and the black elytral spots laro-er 

 and confluent for the greater part of the width. 



5. B. clegaiiS. — Shining black, base of antennae, palpi and legs reddish- 

 yellow; prothorax a little wider than long, flat, sides broadly rounded, margin 

 narrow, piceous and not wider at the base, which is rounded ; hind angles obtuse, 

 much rounded, basal impressions very shallow. Elytra one-third wider than
