EUMENES. 91 



Bess. a. diff — Differs from Mexicanus and all the species of 

 Division Omicron by the form of its petiole. 

 Hub. Mexico ; the Oriental part. Cordova. 



32. E. simulans n. sp. — Niger, sulfureo multipictus, his tri omens ; 



thoiace crasse cribrato-punctato, mesonoto fascii.s 2 llavis; abdomiue 

 punctato, petiolo lineari, apice tenuiter infundibulifbrmi ; secundo seg- 

 niento faciis 2 transversa ilavis. £ . 



9 . Total length, 11 mm. ; wing, 9 mm. 



9. Head transverse-elliptic, very punctate. Mandibles elon- 

 gate, rather hooked at the tip, and armed with three strong 

 lateral teeth. Clypeus polygonal, a little longer than broad, a 

 little emarginate and bidentate at tip. Eyes very large interiorly, 

 their sinus deep, rather triangular. Thorax small, globular, 

 metathorax quite rounded. Petiole moderately long; its second 

 part funnel-shaped, with an impressed point at end. The petiole 

 and 2d segment of abdomen punctate ; this is neither depressed 

 nor compressed. 



Black, with yellow hair. The head beneath, clypeus, mandi- 

 bles, the orbits all round, their sinus, a transverse line on the 

 vertex, sulphur-yellow. Antennae orange-ferruginous, obscure 

 above ; the scape yellow. Thorax beneath and on the flanks, 

 both margins of prothorax, two lines on mesothorax, tegulaa, 

 scutel partly, post-scutel, and metathorax more or less, yellow ; 

 this with a sort of black T. The middle of the petiole, posterior 

 margin, and sides, yellow; 2d segment with two yellow fascia ; 

 the first placed on the middle of the segment, the second being 

 submarginal ; both fused together on the sides; the other seg- 

 ments with sinuous yellow margins ; anus and abdomen beneath 

 quite yellow; the lamellar margin of 2d segment, brown. Feet 

 yellow; the femora brown above. Wings hyaline, washed with 

 amber, a little gray at the extremity. 



Var. The black and yellow colors are more or less extended. 

 Pleurae and metathorax only maculate with yellow. 



7,V.s\s\ a. diff. — A quite distinct species. By its forms only it 

 resembles E. Nortonianus and Cressonianus. The petiole is a 

 little more widened belli ml, and the body much more coarsely 

 punctured. It might be compared with /•/. Srnitkii, americanns, 

 etc.. which have also two fascia* on the 2d segment, but the petiole 

 in these is pyriform and the second segment compressed, etc.
