Anthidium {Dianthidium) parvum, Cresson, 1878. 



This is what has been reported from New Mexico heretofore 

 as A. pudicum, but small examples agree sufficiently with 

 Cresson's description of parvum. It differs from pudicum 

 (which is, perhaps, only a race of parvum) by having the 

 pale markings yellow instead of white or cream-colour; male 

 with no supraclypeal mixxk [pudicum ^ has a small triangular 

 mark) ; a stripe instead of a dot behind the summits of the 

 eyes ; apical margin of male abdomen truncate rather than 

 trilobate. The female sometimes has a yellow frontal spot 

 and a supraclypeal spot.
