severance has been kept up by the keenest de- 

 sire to cast some light upon all these mys-

 across a single specimen of the supposed 

 parasites to which the shell might be at-

 Beetle's? The reader would hardly suspect 

 how my slight acquaintance with entomology 

 was unsettled by this inextricable maze of 

 contradictory facts. But patience ! We may 

 yet obtain some light. 



Let us begin by observing precisely at 

 what spot the eggs are laid. A female has 

 just been fertilized before my eyes; she is 

 forthwith placed in a large glass jar, into 

 which I put, at the same time, some clods of 

 earth containing Anthophora-cells. These 

 cells are occupied partly by larvae and partly 

 by nymphs that are still quite white; some 

 are slightly open and afford a glimpse of 

 their contents. Lastly, in the inner surface 

 of the cork which closes the jar I sink a cylin-

 this artificial corridor, I lay the bottle hori-

The female, painfully dragging her big 

 abdomen, perambulates all the nooks and
