structure, still by selecting his type to draw our characters 

 from, without reference to any of the others, we shall be able 

 to make a sound genus of Anomalon. 



Jurine's genus is distinguished from most of the Ichneu- 

 monidae by the absence of the areolet, or second submarginal 

 little cell, so common to this family, and from many others by 

 the large cell joining the first submarginal one, which is im- 

 perfectly closed next the posterior margin in A. Vesparum,; but 

 it is not so in Jurine's type, A. Icetatorius. There are a con- 

 siderable number of species that agree with these insects in 

 their wings ; but we shall not venture to place them in the 

 same genus at present, as they present other differences. 



1. A. laetatorius Fab. Panz. 19. 19. mas. — 100. 14. fern. — 



102. IS. fern. var. — Middle and end of July upon plants 

 in meadows and gardens. 



2. Vesparum Nod, 



For specimens of this Anomalon (probably females), one of 

 which is figured, we are indebted to the zeal and liberality of 

 Mr. R. Wood of Manchester, who transmitted them with the 

 nidus and following observations upon this singular insect. 

 " In examining the combs of some Wasps' nests, (near the 

 end of July probably,) in one of them I discovered many cells 

 about half the length of those of the Wasps, and capped with 

 wax. I put the comb into a glass jar, and the day following 

 had the gratification of finding that three had eaten their way 

 out of the cells. I think they were the liveliest insects I ever 

 saw ; yet on going to look at them again, I found that several 

 Wasps had emerged from their cells and had actually eaten 

 two of them. I then took out the comb, and destroyed the 

 young Wasps by running a pin through them in their cells, 

 and again put the comb into the jar ; and in a few days three 

 others came out. I fed them with honey, and they seemed 

 to be very fond of it." Nothing has transpired since the comb 

 has been in our possession ; but we expect that those cells 

 containing the Anomalon, will produce the other sex of the 

 insect in the course of next summer. The cells occupied were 

 in various situations, from two to four together : each cocoon 

 was hexagonal, and filled the inside of the Wasp's cell; it was 

 very tough and silky, round at the bottom and flat at the top. 

 It is worthy of remark, that the cells of the Wasps containing 

 the Anomalon were closed like the others ; and upon opening 

 them the exuvia of the Wasp's grub filled n space about one- 

 third of the cell, from which we conclude that the eggs were 

 deposited in the bodies of the larvse and lived in them till they 

 became nymphae. 



The plant is Inula pulicaria (Less Fleabane).
