200 EYE SPY 



teen dark red, egg -shaped chrysalides of the es- 

 caped larvDe. Two weeks later, upon opening the 

 box, a swarm of flies flew out. I was enabled to 

 keep two of them. They were almost exactly 

 Hke the common house-fly to the ordinary ob- 



server, but belonged to a distinct genus. At this 

 writing, in the absence of my specimen, I cannot 

 give the name by which they are known in learned 

 circles, but I think I am safe in saying that they 

 probably belong to the group called Tachina, a 

 family of parasitic flies which spend their early 

 lives in a similar questionable manner, to the 

 probable discomfort of potato - bugs, caterpillars, 

 and other accommodating insect hosts.
