The genus Anaulacus Semeuov receutly created by that 

 author [Revue Russe d'Entomologie III p. 173, 1903] is of 

 interest, in that it supplies a connection betweeu the already 

 known gênera of Aulacinae. We have Deraiodontus Brailley 

 and Prùtâulacus Kiefer with four pectinate teeth ou the tarsal 

 claw, Oleisoprifiter ßradley with three teeth, Anaulacus Se- 

 menov with two, Aulacus J urine with one, and Pammegiseläa 

 Provancher with uone. Certain species of Oleisoprister, as 

 O. mbfirmus. Viereck, have the third tooth extremely minute 

 and difficulfc of détection. Tt is just possible that such may 

 be the case in sibiricola Semenov which forins the type of 

 Anaulacus. A. rufitarsis Cresson which SemenOv places pro- 

 visioually in Anaulacus does not belong there, as it has very 

 distinctly only one tooth, is iudeed very typical of the re- 

 stricted genus Aulacus. The genus Pammegiseläa Provancher 

 is the most distinct of any of the geuera, not only the ab- 

 sence of teeth on the tarsal claw, but the lack of venation 

 in the bind wings, and the immense prolongation of the fe- 

 male coxae within serve to completely separate it from all 

 the others. Its habits also are différent, and have several 

 records of its parasitizing Xiphjdria. The other gênera seem 

 to make natural groups of species so far as the American 

 forms are coucerued. It would be interesting if some one 

 with access to the European collections would place the other 

 forms in their gênera as limited and see if this does not hold 

 good for them also. I feel certaiu it would in all cases ex- 

 cept Deraiodontus, and coucerning that aud am not so sure 

 at présent, altho I hope it would prove no exception.
