projections of the metathorax, the unusually short tar sal joints 

 and in venation ; thz. submarginal vein is davate and does not 

 reach the costal edge ; the marginal vein is therefore absent. 



Another rare Chalcid which I was charmed at discovering 

 was Eunotus cretaceus Walk. Walker described it in the En 

 tomological Magazine (vol. ii, p. 298) and placed it with the 

 Pteromalina . Ratzeburg in Forstinsecten, Band iii, p. 227, 

 1852, redescribed it under the name Tritypus areolatus, from a 

 specimen reared from a Coccid on Salix aurita. Forster, in his 

 Kntomologische Studien, 1856, ii, p. 63, rechristened it under 

 the name Megapelte, as the name Eunotus had been given 

 previously by Dejean to a genus of beetles, and briefly de 

 scribed what he supposed was a new species under the name 

 .Megapelte nigridavus reared from Coccus vitis. Sixteen years 

 later (1872) Walker in his Notes on Chalcidiae, pt. v, p. 100, 

 restores the name Eunotus > and briefly dismisses the subject by 

 saying : " Megapelte Forst. is another name for Eunotiis which 

 has also been named Tritiphus and is an example of a small 

 but distinct family." 



After a careful study of the species I have arrived at a dif 

 ferent conclusion from these authorities. I believe there is but 

 a single species, and it is neither a Pteromalid nor the type of a 

 new family but falls naturally in the subfamily Aphelinince, al 

 though in its cephalic, antennal and scutellar characters it 

 shows a strong affinity with the Encyrtinae. It is a closely 

 connecting link between these two groups with the antennae of 

 an Encyrtid, but with the weak middle tibial spur and the 

 mesonotal furrows of an Aphelinid. 



Forster evidently saw its relationship to this group and 

 probably excluded it only because it had ii -jointed antennae 

 for he remarks : ' ' Nicht bios die eilf-gliedrigen Fiihler sondern 

 auch die Kopf und Hinterleibsbildung geben ihr ein eigen- 

 thiimliches Geprage. Der ganze Habitus erinnert nicht un- 

 deutlich an Agonioneurus Westw. (==.Myina Nees)." 



Walker also as early as 1847 (Annals of Mag. Nat. Hist., p. 

 229) .said that it was allied to Choreius ineptus Dalm. and 

 Encyrtus eucopiformis Kollar. 



At some other time I shall probably give additional notes on 

 the Hymenoptera. 



Just behind the Hymenoptera are the Diptera, all well ar 

 ranged and containing many thousand named species, as well 

 as a large amount of new and unworked material awaiting the 

 specialist. 



The Hemiptera, except in three or four families, are badly 

 arranged, and a large portion is still unnamed, especially in 

 the Homoptera. Dr. Karsch is making strenuous efforts to 

 bring all into systematic order, but with his other work it
