Texas; Arizona; New Mexico. I have seen the type of Photopsis 

 picus Cockerel], and have no doubt as to its identity with Chyp holes 

 attenuatiis, with which the description agrees. Photopsis mellipes 

 Blake, which I formerly held to be identical with Belfragei/^ is the 

 same as attetmatiis.

Colorado. This species is peculiar by having the fourth and 

 fifth ventral segments furnished with two brush-like bunches of 

 stiff, bristle-like hairs, thereby differing from all the other known 

 species. 



M. j^ecullaris is quite distinct in the shape of first abdominal 

 segment, facetted eyes and silvery ornamentation from the other 

 species of the genus. These characters, in this case, are not of 

 greater value than subgeneric.
