INSECTA HYMENOPTERA. 175 



cubital areolse, fourth joint of the tarsi lobed ; a new species, Rh. Abbottii, 

 from Georgia, in North America. 



POMPILII. Dahlbom (Hym. Europ.) has described a considerable number 

 of species, both European arid exotic, which are distributed under the fol- 

 lowing genera : Dolichurus, Spin. ; Ceropales, E. ; Salim, E. ; Entypus, Dahlb.; 

 Pliniiceps, Latr. ; Aporus, Spin. ; Pompilus, E. ; Ayenia, Schiodt. ; Prioc- 

 , Schiodt. ; Pepsis, E. ; Hemipepsis, Dalilb. Tlic characters of the new 

 genera, Eutipus and Hemipepsis, are not stated, and I am also ignorant of 

 what they rest upon ; the former contains a new species, E. ochrocems, from 

 Algiers; the latter comprises Pomp. flaws, E., and two new species. The 

 author regards Pomp, sanyidnolentus, E., as a Saliits, but incorrectly, for the 

 Eabrician species constitute a very peculiar form. 



Eischer v. W. (1. c.) has described Pompilus sesqmalterus and P. alienus, 

 the former from the Lower Wolga, the latter from South Russia. 



Gueriu (Mag. de Zool. Ins. pi. 114, 115) has instituted three species of 

 /''/,///>//#.?, of which, P. Paulinieri, from Senegal, is new ; P. Brentonii, from 

 Senegal and Sicily, is nothing but P. crocicornis, Kl., lastly, P. Graellsii, 

 from Barcelona, is undoubtedly identical with P. luteipennis, E., although 

 Eabricius does not mention the black base of the thighs, which induces the 

 author to demur. 



LAEKAT^;. Dahlborn (Hym. Europ.) has comprehended under this family 

 the genera P alarm, Latr. ; Tachytes,^ss\z.; Z/m, F.; Larra, Latr.; Astata, 

 Latr. The genera Tachytes and Larra will scarcely admit of being sepa- 

 rated, as is indeed apparent from the circumstance that Tachytes pat/ana, 

 Dahlb., which is distributed over a great part of America, is very nearly 

 allied to Larra anathema. Besides which, it may also be remarked, that 

 TacJiytes tricincta, Dahlb., in the Berlin collection, is not an unpublished name, 

 as he states it, but Liris tricincta, Eab. (and the female, Liris varians, E.), 

 and that Liris oricJialcea, Dahlb., is also a Eabrician species, viz. Pomp. 

 fwemorrhoidalis, E. 



Spiuola (1. c.) has instituted a new genus, Dryudella, which differs from 

 Larra and Liris in this, that the radial areolahas a large accessory areola, as 

 in Dimorpha ; and from the latter, in the crescent form of the third cubital 

 areola, as is the case in Lyrops. How the ocelli are circumstanced is not 

 mentioned. The author comprises in this new genus, Dimorpha cincta, Perris, 

 and a new Spanish species, Dr. Ghilianii. 



He has also (ib.) characterized a new species of Oxylelus, 0. 

 and remarks upon it, that it may probably be a variety of his 0. 

 However close the affinity, it appears to me, that the South European 

 species is distinct from the Egyptian. 



NYSSONII. Dahlbom (Hym. Eur.) includes in this family Alyson, with a 

 new European species, A. Ratzeburyii, Harpactus, Stizns, LestipJiorus, Hop-
