8. The Species or Aulocara. 



Aulocara Scudd. has as synonyms CEdocara Scudd. and Coloradella 

 Brunn. (See Can. Ent., XXIX. 7"), and Psyche, VII. 71.) No spi 

 have been referred to the last named, but to the others live uomiual spe- 

 cies have been referred; eUiotti Thorn., cceruleipes Scudd.. decern Scudd., 

 strangulatum Scudd., and scudderi Brun. Scudderi, as ha- been Bhown 

 by McNeill, belongs to Ageneotettix (Eremnus). The other four all 

 represent a single species, which must bear the oldest name, elliotti. 

 Nevertheless we possess four species which may lie separated by the fol- 

 lowing table : — 



Table of the Species of Aulocara. 



a 1 . Fastigium of vertex broader than long, its front margin obtusangnlate ; meta- 

 zona feebly tumescent, its bind margin not very broadly obtusangulate ; bind 



tibia 1 roil rufum sp. nov, 



a-. Fa8tigium of vertex at least as long as broad, its front margin rectangulate or 

 acutangnlate ; metazona plane or nearly plane, its bind margin broadly obtus- 

 angnlate ; bind tibiae purple,* or glaucous. 

 i 1 . Pronotum Btrongly constricted mesially, the disk with more or less conspicu- 

 ously decus-ate markings, the lateral carina) strongly divergent in front and 

 behind. 



c 1 . Male antenna' as long as tliorax and abdomen combined ; lower margin of 

 lateral foveolae of vertex obsolete or obsolescent ; tegmina generally immacu- 

 late, much shorter than the long hind femora / moratum Bp. nov. 



* The hind tibia- of A. paraUelum are not known, but are presumably purple.
