EUMENES. 91 



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

 Division Omicron by the form of its petiole. 

 Hub. Mexico ; the Oriental part. Cordova. 



32. E. simulaias n. sp. — Niger, sulfureo multipietus, histrionicus ; 

 thorace crasse cribiato-punctato, mesonoto fasciis 2 flavis ; abdoniiue 

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

 meuto faciis 2 trausversis flavis. f . 



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 inferiorly, 

 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, tegulas, 

 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. 



Bess. a. cliff. — A quite distinct species. By its forms only it 

 resembles E. Nortonianus and Cressonianus. The petiole is a 

 little more widened behind, and the body much more coarsely 

 punctured. It might be compared with E. Smithii, americanus, 

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

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