SPECIES DUBLE. 



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

 if they are solitary wasps. 



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

 r.alis. 



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 infundibuliformi," which is 

 in entire contradiction with "forte viera varietas" of E. arcuatus. 

 — It may be s Monte zumia ; M. rnortuorum? or some allied 

 species. The color of the wings is not given. 



2. Eumenes forniicaria Fabr. Syst. Piez., 288, 15. — Amer.,merid. 

 This may be a Montezumia or a Polistes. 



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

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

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



4. V. cineraceus 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. Mnotata Fabr. Syst. Piez., 266, 71.— America meridionalis. 



Has some similarity to Odynerus crypticus Say. 



*2. V. da-rial a Lichtenstbiit, C. M. H. 203, n. 173— Weber. Observ. 

 Entotrr., 103, 8. — Nigra, ndynero parietum paulo major ; thoracis mar- 

 gine litnrisque basi uoeuntibns flavis ; scutello flavo ; abdomine cingulis 

 5 flavis ; alis albis venis margineque antico fuscis. — America.
