Two Rare Wasps (Hym.). 



In the Rcbn and Hebard material I have found two species of Hy- 

 menoptcra which I think should be recorded. 



Mutilla sloxsonac Fox. Tr. Am. EnL Soc XXV. p. 373, March. 1899.

 second specimen was captured at Loggerlwad Key, Dry Tortugas.

Dragonflies Devouring Winged Ants (Odon., Hjmcn.). 



On the morrmiK of April 15. 1912. as I was sitting on the hotel 

 porch at New Smyrna. Florida, about 10 o'clock, I observed a large 

 number of dragonllies gathering and circling through the air. The 

 number of these insects increased until they were as numerous as 

 I ever saw insects around an arc light in a northern counly scat in 

 imer. There appeared to be several spedcs: one a very large 

 green, one that teemed purplish and one that was tmaller 

 aiiU showed brownisb-rcd. Upon going to the pboe about which thcgr 

 were circling. I discovered a swarm of winged ants upon a front 

 fence post These, when they had climbed the post to the top. took 

 wing, sometimes singly, sometimes many at oooe. The gathering 

 dragonHies would dart upon them and setic and devour them. Many 

 were caught before they were a yard above their starting place. None 

 appeared to rise higher than ao feet We watdied them for some 

 minutes and in that time, while hundreds took wing, nooe a p pe ar ed to 

 escape their enemies. A dragonfly seldom nrisacd his mark. If an 

 ant was missed, another destroyer got it. The dragonflies are gener- 

 ally known here as mosquito hawks. By the time the first colony of 

 winged ants was gone another smaller company made its appearance 

 about the porch foundation and the dragonflies turned their attention 

 there until they were destroyed.— Amos W. Butljcr. Indianapolis, 

 Indiana. 



(Thu note recalls the observation by Mr. C. W .Johnson, recorded 

 in the News, VoL x. p. 2191 Sept.. 1899. to the effect that Aeskna 

 ingtiu, probably the *S'ery large brilliant green" species mentioned 

 above, "is extremely destructive to bees in Florida," and also the re- 

 mark of Mr. Davis. /. c, xxv. p. 191, on dragonflies catching smaller 

 buttrrHics in the same State. — Eo.]
