4 females, Fridley sand dunes, Anoka County, July 2G, 1923 (R. W. Daw- 

 son) ; 6 females, Fridley sand dunes, Anoka County, July 28, 1922 (Paul 

 Gilmer) ; 4 females, Fridley sand dunes, Anoka County, July 28, 1922

 1922 (A. T. Hertig) ; 12 females, Fridley sand dunes, Anoka County, August 

 8, 1922 (C. W. Johnson) ; 5 females, Anoka County, Jjme 30, 1923 (H. H.

 August 14, 1920 (C. B. Philip) ; female, Halsey, August 16, 1923 (R. W. 

 Dawson) ; female, Mitchell, August 22, 1915 (E. M. Partridge).

Texas : Female, Richmond, June 22, 1917 ; female, Fedor, June 11, 1902 ; female, 

 Lee County, August 7, 1905; female. Twin Sisters, May 25, 1918 (J. C. 

 Bradley ) ; female, Valentine, Presidio County, July 8, 1917 ; male. 



Attention is called to the fact that the postero-lateral tubercles of 

 the head are rather weakly developed and are, therefore, more or 

 less obscure, according to the position of the head. In some speci- 

 mens a casual observation may give the impression that the posterior 

 margin of the head is evenly rounded but a careful inspection will 

 show the tubercles to be present. The types of caneo and mixtura 

 have been examined and found to be identical. The specimens vary 

 in length from 5 to 9 mm. 



I have examined the type of M. myrrha described by Fox in his 

 j<^noup ivipenalis { = Photopsis Blake pt.), and find it to be identical 

 with this species. The specimen has a rubbed appearance and there- 

 fore does not have the characteristic appearance of caneo. It is 

 not a Photopds at all and is unquestionably Blake's species caneo.
