Eupelmus (Antigaster) mirabilis, Walsh. — The rearing of a number 

 of specimens of this interesting Chalcid from eggs of Microcentrum 

 retinetvis collected by Prof. Comstock at Jacksonville, Fla., has given me 

 an opportunity to verify a suspicion which I have for some time enter- 

 tained, namely, that there were no grounds for the founding of the genus 

 Antigaster. A comparison of the specimens with Walsh's description 

 shows the latter to be an excellent one ; but there is not a single struc- 

 tural character mentioned by him as belonging to this "anomalous" genus, 

 but what belongs equally well to the old genus Eupelmus Dalm. As to 

 the habit of elevating its abdomen which Walsh considered so particu- 

 larly anomalous, it is such a well-known thing to European writers that its 

 seeming absence in E. Geeri caused Ratzburg a momentary doubt as to 

 this species being a Eupelmus (see Ichn. d. Forstins, iii., p. 199). In the 

 allied genus Eusandalum Ratz., and possibly in other Eupelmide genera, 

 the same thing is seen, but in a slighter degree. Prof. Riley seems to 

 have suspected this when he says: (6th Mo. Rep., p. 162) "No other 

 species is so curiously constructed for rolling backward into a perfect
