publication of " Jurinean " Genera of Hymenoptera. 367 



Prof. Jurine, are taken solely from the Situation and 

 Attachment of the Unterleib (Abdomen) on to the Brust- 

 stilck (Thorax), in short as follows : Ordo I. Abdomine 

 prorsus sessili. Ordo II. Abdomine supra thoracem infixo. 

 Ordo III. Abdomine petiolato : petiolo pone thoracem infixo. 

 Accordingly under these three Orders are placed the whole 

 company of Gattungen (Genera) Gall- Schlupf- Blatt- Gold- 

 etc. Wespen, the Wald- Blumen- Trauer Bienen, Hummeln, 

 Mutillen, Ameisen* etc.

Notice of a new Entomological Work, by Hr. Prof. Jurine 

 of Geneva. {Conclusion.) 



The Main characters (Characteres primar.) of the Genera 

 themselves, rest indeed chiefly and almost exclusively on 

 the Vessels or the Nerves and Veins of the Wings, according 

 as these sometimes more, sometimes less, interlace them- 

 selves by their anastomosis-hkef Concatenations and reticu- 

 late Connections, and form thereby variously shaped Cells, 

 Lattices and Nets ; but at the same time, lest this standing 

 Character — so admirably adapted by reason of these it 

 may be great Modifications, for the Estabhshment of 

 natural Genera — should deteriorate into a cramping One- 

 sidedness, the various Shapes of the Fiihl-horner (Antennae) 

 and likewise the Kinnladen (Mandibulae) are also taken in 

 subsidium as Characteres secundarii ; though the Anasto- 

 moses of the Wing-veins and Nerves are still always the 

 foremost or standing Characters of the genera. 



At the same time it so happens that in the Establish- 

 ment of the Genera by help of these Anastomoses, some 



* Panzer uses these same popular German names, along with 

 the Latin names cited from Syst. Ent., throughout his Fn. Ins. 

 Germ. Most of them are still in use colloquially in German ; but 

 we do not know whether this is the case as to the Waldbienen, 

 Blumenbienen, and Trauerbienen, and have failed to gather from 

 his work how he distinguished these groups from one another. 

 Together they seem to include most Anthophila, except the 

 Humble-bees (Hummeln). 



t By this technical word Panzer's contemporaries {e.g. Kirby) 

 were accustomed to express the running of one nervure into another, 

 as a tributary discharges into a river, cf. (French) deboucher and 

 (Engl.) disembogue. arSfui = bouche, mouth.
