therefore be considered independent, there seems little doubt that 
those of Calvert and Stepanoff were entirely independent, and, as 
Osten Sacken points out, it is a little remarkable that in three 
different parts of the world similar original facts on the same 
family and even the same genera were being observed during the 
same year. Such coincidences are not at all rare in the history 
of discovery ; indeed, they are sufficiently frequent to lead to the 
conclusion that they are due, in no small measure, to similar fa- 
vorable opportunities owing to the abnormal abundance of the 
species observed. 
The correspondence between Stepanoff's observations and my 
own go still farther, for he also found an Anthracid, namely, 
Mulio obscurus, similarly feeding in the larva state on the locust 
eggs, just as I found Triodites mus associated with Systcechus 
oreas ; while he discovered also an Anthomyia egg-parasite 
which he determined as Anthomyia radicum, thus referring it to 
the very species to which originally I referred ours, but which 
was subsequently decided by Meade to be Anthomyia angusti- 
frons. 
While touching on the egg-parasites of the Acridiidae, it may be 
of interest to mention that I have recently received from Dr. A. 
Ernst, of Caracas, Venezuela, a number of specimens of a Scelio 
which he found very abundant in the eggs of Acridium pere- 
grinum. The receipt of the specimens from Dr. Ernst has led me 
to study more carefully the species originally described as Calopten- 
obia ovivora, but which was subsequently, upon further examina- 
tion, referred to Scelio famelicus Say. The result of the recent 
studies would indicate that Caloptenobia ovivora, while belonging 
properly to the genus Scelio, is really quite distinct from Scelio 
fameliczis, and will therefore hold good specifically. The speci- 
mens were bred from eggs of CEdipoda Carolina by Mr. S. H. 
Scudder. Those from Dr. Ernst are larger and constitute a new 
species which I propose to call ernstii, while others bred from 
the eggs of Caloptenus atlanis constitute a third species inter- 
mediate in size between the other two, and which will be 
described as caloptenorum. Dr. Ernst has also found some 
other parasites of the locusts themselves, and notably Priononyx 
striata Sm., just as we found P.atrata St. F. attacking spretus ; 
also a species of Mermis. All these facts go to show how great
