MACIIOGASTEU. 



On 



he had considered Macroija^ter to belong to the Pimi'Mn,!: and 

 llemigaster as intermediate between the Cia'PTiN.i; and iciixicu- 

 MoxiN.i;, in which hitter he liad then unhesitatingly placed 

 Chrcusa, proposing for it and liothnei/ia a new group, termed by 

 him lioxHNEYiN^. Subsequent systematists have allowed Chrensa 

 to remain in the Joppides and placed the remaming genei-a, as a 

 group apart, in the CryptiNjE. Artkula, however, has the abdo- 

 men subimpressed, as in the Pimplin^e ; Mucrogaster has the 

 petiolar spiracles before the centre of the segment and is com- 

 pared by Cameron throughout with Plmpla {cf., however, Ann. 

 Nat. Hist. XX. 1907, p. 17) ; and the neuration is identical in 

 Hemigaster, whose facies in other respects is certainly strongly 

 Cryptid. I consider them very naturally placed as a Cryptoid 

 group of the PiMPLiis^iE, immediately preceding the equally 

 puzzling XoKiDiDEs. None of the Oriental species appears to 

 have been yet bred.

* The generic name, Macrogaster, was applied to Coleoploi-a in 1805 by 

 Thuuberg, and to Arachnida in 1843 by Miescli. It is consequently jn-obable 

 that tiie ]ryineno])tcrous geiuis \\\\\ liave ere long to be I'cnanied ; l)iit I am 

 not aware that citlier of tlie eailicr genera are in nse by systeniattsts and 

 prefer to retain names until their alteration becomes of some use, wliieli does 

 not appear to bo the case liere. IJrulle's title is retained by Dalla Torre in 

 iOtJl and Ashinead in I'JtK). Miicrogastrr was also applied to a genus of 

 Zeuzerid moths by ])uponchel (';/'. JJoubleday's List atid Newman's IJritish 

 Moths, p. 17, etc.).
