CERCERIS FLAVOTROCHANTERICA, new species. 



Judgmg from the description this species is related to mexicana 

 Saussure, but the propodeal inclosure and markings are different. 

 There is some affinity with sexta Say, but the different colored legs 

 readily separate it from that species. 



Propodeal inclosure obliquely striate laterally, shining, with a 

 medial, longitudinal furrow.

 apically, the middle tooth the largest and truncate apically; head 

 with large, rather close, distinct punctures, those of 

 the cl3^eus more separated; postocellar line distinctly 

 shorter than the ocellocular line; nasal margin of eyes 

 slightly converging to cly|:)eus; third antennal joint dis- ^j^ lo.— emargi- 

 tinctly longer than the fourth, apical joint not hooked, kation of the
