I am looking for a very specific set of mugs (4 in total with
coasters):

The series is called “Bug Me” 
by Alicia Tormey Designs 
Signature Housewares Incorporated 
Stoneware
Made in China 

I found the artist's website, but unfortunately she does not sell
directly to customers. Here is a picture of the set I am looking for:

I already have the dragonfly and the bees, so I am looking for the
ladybugs and butterflies. I don't mind having to purchase the whole
set again, as long as it includes the ladybugs and butterflies. Of
course, I am open to purchasing either of those individually as well.
I would prefer the coasters be included, but they are not necessary.

I found this set (excluding the butterflies – my ladybugs broke)
several years ago at Price Club and have not seen them since.

I am looking for information on where I can purchase them – a phone
number, email address, store address or even an individual who just
wants to sell their old set would be fine.

Thanks for your help, if there is anything I can add please don’t
hesitate to ask a follow up question.

I know that this isn't much help, but if you'd like to add to your
dragonfly set, there are a couple for sale on eBay:

The eBay seller that juggler referred to is also selling the ladybugs:

You'll have to hurry, the auction ends tonight.
