Anthklium {Dianthidium) parvum, Cresson, 1878. 



This is what lias been reported from New Mexico heretofore 

 as A. pudicuWf but small examples agree sufficiently with 

 Cresson's dcscri|ition of parvuvi. 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 m\.\\\i {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 tlian 

 trilobate. The female sometimes has a yellow frontal spot 

 and a su])raclypeal spot.
