SPECIES DUBIiE. 



The following species I cannot discover, and it is very doubtful 

 if they are solitary wasps. 



1. Etimenes atrata Fabr. Syst. Piez., 287, 12. — America meridio- 

 nalis. 



If this species has the same form as E. arcuatus, to which 

 Fabr. alludes, it may be the black variety of this from India, 

 but Fabr. says ; " primo segmento infundibulifbrmi," which is 

 in entire contradiction with u forte mera varietal of E. areuatus. 

 — It may be o Monte zumia ; 31. mortuorum? or some allied 

 species. The color of the wings is not given. 



2. Eumenes formicaria Fabr. Syst. Piez., 288, 15.— Ainer. merid. 

 This may be a Montezumia or a Polisl<'$. 



3. Vespa emarginata Gmel. Ed. Linn., 2759, 26. — MueiAeb Ed. 



Linn. Ins., II, 886, 26. — Clypeus emarginatus. Abdomen nigrum, petiolo 

 utrinque dente instructo. — America — (Eumenes?). 



4. V. cilieraceus Fabr. Syst. Piez, 260, 37. — America (? Alaslor 

 melanosoma ??) 



5. V. atrata Fabr. Syst. Piez. 260, 36. — America insulis (a male). 

 seems allied to Alastor melanosoma, but with hyaline wings. — Monte- 

 zumia ? 



6. V. 1)iliotata Fabr. Syst. Piez., 266, 71. — America meridionals. 



lias some similarity to Odynerus crypticus Say. 



'■?. V. daedala Lichtenstein, C. M. n. 203, n. 173 — Webbr. Observ, 

 En torn., 103, 8. — Nigra, odynero parietum paulo major; thoracis mar- 

 gine liturisque basi ooeuntibus ilavis ; Boutello flavo ; abdoraiue oingnlia 

 5 ilavis; alis alhis vein's margiueque antioo fasois. — America.
