This is currently the most up-to-date treatment of the genus Pepsis...published in three parts between 2000 and 2005 (by two different publishers).

Part 1. Introduction and the P. rubra species-group. Zool. Verhandel., vol. 332 (2000), pp. 1-86. (Full Text)
Part 2. The P. grossa- to P. deaurata-groups. Zool. Verhandel., vol. 338 (2002), pp. 1-134. (Full Text)
Part 3. The P. inclyta- to P. auriguttata-groups. Zool. Meded., vol. 79-5 (2005), pp. 1-305. (Full Text)

This work covers all the (many!) New World taxa in Pepsis...most of which occur south of the US, and thus outside our area. Below is a list of the 14 currently recognized species recorded from our area, indicating the Part and page number in Vardy where its description/discussion appears:

      P. aquila: Part 2, p. 63
      P. basifusca: Part 3, p.141
      P. cassiope: Part 2, p. 92
      P. chrysothemis: Part 1, p. 74
      P. grossa: Part 2, p. 58
      P. marginata: Part 2, p. 67
      P. menechma: Part 3, p. 131
      P. mexicana: Part 1, p. 65
      P. mildei: Part 3, p. 229
      P. pallidolimbata: Part 1, p. 77
      P. ruficornis: Part 3, p. 232
      P. sommeri: Part 3, p. 96
      P. terminata: Part 2, p. 68
      P. thisbe: Part 1, p. 60

A number of previous species names appearing in earlier treatments [e.g. Hurd(1)(1952), Townes(2)(1957), and Krombein(3)(1979)] have been changed by Vardy. Below is a list of old names for species in our area, followed by their new names under Vardy's synonymies:

      "P. angustimarginata" = P. basifusca
      "P. arizonica" = P. cassiope
      "P. azteca"= P. sommeri
      "P. cerberus" = P. menechma
      "P. elegans" = P. menechma
      "P. formosa" = P. grossa
      "P. saphirus" = P. ruficornis
      "P. venusta" = P. terminata

no link?
links don't work thanks

Ever-blossoming dead links...a bane of internet operability!!
Wish there were a built-in rerouting script that would automatically set up "redirects" whenever IT (or other) folks decide to fiddle with their existing server's file folder & filename structures!! Every time a change is made unknowns scads of dependent "downstream" links can get severed!

Anyway, all's well in this case (for now)...using Duck-Duck-Go I found the following replacement links (who knows how long until they'll be changed? ;-):

*) A single "DANS/Narcis" search results page with links to portal pages for downloading the PDF's for each of the 3 parts of Vardy's venerable Pepsis revision...with, in particular, the:

  1) Portal page for Part 1...with direct PDF download link =;

  2) Portal page for Part 2...with direct PDF download link =;

  3) Portal page for Part 3...with direct PDF download link =

PS: I suppose I shouldn't get too irritated about the dead links here...after all, it's quite a gift that so many of us can have such relatively easy access to thousands of formerly very hard to obtain scholarly works like Vardy's! Thank you Mr. Vardy, Naturalis Biodiversity Center, and the multitudes of others that make it all possible :-)

thank you
thank you for your help Aaron :)
