$ c? (Oued Nca and El Arish). 

 The above specimens exactly resemble specimens from Biskra determined for 

 me by Kohl many years ago when the 3 was nndescribed. I described it in 

 Trans. Ent. Soc. Lond. Part III. 1897. 



29. Parasphex albisectus Lep. ? (Laghonat). 



30-31. Parapsammophila dives Brull. ? ? (Ghardaia).

41. Tachysphex eduardi Sannd. ? (Ain Sefra). 



(Saunders's description was published after his death in Trans. Ent. Soc. 

 Part IV. 1910.) 



42. Tachysphex panzeri Kohl. ? ? (Oned Nca). 



43-44. Vespa germanica F. ^ £ (Oran and Hammam Rirha). 

 45-46. Polistes gallicus L. 2 2 ? (Ain Sefra). 



Perhaps only large £ $. I do not know how to distinguish satisfactorily the $ $ 

 and ? 2 of this group. The character of size seems hardly sufficient. 



47-48. These are clearly £ g of P. gallicus (Ain Sefra). 



49-50. Also £ ^ of P. gallicus, somewhat less copiously ornamented than those from 



Ain Sefra (Laghouat, and Hammam Rirha). 

 51-53. Also $ ^ of P. gallicus, highly coloured like the Ain Sefra specimens 



(Hammam Rirha). 

 According to Saussure's criteria for distinguishing the forms gallicus and 

 biglumis, all the above specimens 45-53 are to be assigned to gallicus, which 

 is certainly the prevailing if not the only form in Algeria ! 



54. Eumenes dimidiatipennis Sauss. ? (Ain Sefra). 



I have previously met with this form only from Oriental districts (Egypt, etc.) 

 and do not know of any other record of it from Algeria, except the specimens 

 collected by Dr. Hartert in the sandy tract of El-Arich, at El-Golea, and in the 

 Southern Oued Mya in 1912 (cf. Nov. Zool. xx. 1913, p. 599). 



55-57. Eumenes arbustorum Penzer var. algira Schulz $ 2 (Ghardaia). 



58. „ „ „ „ „ 2 (Oued Nca). 



59. Odynerus {Hoplopus) variegatus F. ? (Hammam Rirha). 

 60-61. Odynerus (Lionotus) crenatus Lep. ? S3 (Ghardaia). 



The distinction between crenatus and dantici seems rather doubtful. If the 

 forms can be separated specifically, these specimens belong (I think) to the former. 

 One of them has the postscutellum immaculate, in the other it is lined with yellow.
