208 THE CANADIAN ENTOMOLOGIST. 



Osborn had not seen the type of Duzci nor that o{ perplextts. He knew 

 I had the type of perplexiis, and I have offered to loan him anything I 

 had. I have specimens of Duzei froai Colo., however, that are quite 

 typical as to length of oviduct, brown veins in wings and coloration. I 

 did not refer perplexus to a varietal form of pallidiis without carefully 

 sifting all the evidence, but that it should be Duzei is an impossibility. 

 The Duzei of Osborn becomes a synonym oi perplexus^ probably. 



The types of distinctus and mimicus are in my collection, where they 

 have been since the day names were put on them. So Prof. Osborn's 

 remarks on this point are not exact. My collection is now in the 

 National Museum, where anyone may study these types at their leisure. 



Since producitis was described, I have collected many perfectly- 

 formed, healthy specimens of it, both male and female, and I can only say 

 that they are absolutely uniform in the "remarkable characters" indicated 

 in the original description, and that these characters are most positively 

 jiot " due to the vertex having been pushed forward and crushed along a 

 middle line. If I remember correctly, the type is not a " crushed speci- 

 men." Prof. Osborn has not seen the type, though he could easily have 

 done so. I fail to see how crushing could produce the peculiar inflation 

 found in the head of this species.
