ON THE SYSTEMATIC POSITION OF THE ORTHOPTEROUS 

 GENUS AULOCARA, SCUDDER. 



BY A. N. CAUDELL, WASHINGTON, D. C. 



Too late for correction, I find that in my recent paper on western 

 Orthoptera* I have redescribed Scudder's Anlocara rufuin as a new 

 species under the name guajiieri, placing it in the not very nearly related 

 genus Heliasttis. This unfortunate mistake was brought about by the 

 uncertain position of the genus Aulocara, which possesses both tryxaline 

 and oedipodine characters. The general aspect of the species of the genus 

 is certainly very strongly oedipodinean and the characters of the declivate 

 vertex, subperpendicular front, filiform antenna, small round eyes, obsolete 

 lateral carinae, twice or thrice severed median carina, wrinkled pronotum, 

 and of the generally present intercalary vein, all indicate close affinity to 

 the Q^dipodinse. McNeill, in his revision of the Tryxalinaef, excludes this 

 genus, but Scudder considers it to belong to that group. (Edocara, 

 Scudd., and the invalid genus Coloradella of Brunner von Wattenwyl|, 

 are synonyms of Aulocara, and under the former name Saussure places it 

 in the Q^dipodinae§, and Coloradella was established as a tryxaline genus. 

 Thus there is considerable difference of opinion among specialists as to 

 the systematic position of Aulocara. Upon thoroughly studying the 

 group characters exhibited by our species of this genus, I feel very certain 

 that its logical position is in the CEdipodinpe.
