214 Psyche [December 



Both these varieties seem to coincide in range with Phelister sub- 

 rotundus. 



Two more species, vermis Say. and saunieri Mars, require 

 attention. These two are very close but differ in essential points. 

 In vermis the thorax is very sparsely and unevenly punctate, as is 

 the pygidium, the form of the insect is distinctly elongate, and all 

 of the twenty -four specimens which I have examined have a dis- 

 tinctly reddish tinge, thus producing a rusty appearance, although 

 the general color is black. Saunieri is proportionately broader, 

 and has the thorax evenly and rather densely punctate, the pygid- 

 ium is also evenly punctate but not very densely, the color is a 

 clear, shining black without a trace of reddish. 



I believe that the latter is extensively confused with vermis in 

 collections as all the eight specimens that I have seen have been 

 sent to me under that name.
