beneath pale, with the femora and tibiae dark at the apex, tarsi dark. 

 Length 6 mm., mdth 3 mm. 



Type: Female, USNM 61817, taken on a plane from Mexico at 

 Houston, Texas, December 5, 1947. One male in BAI without 

 locality label. 



Remarks: This species so closely resembles D. glabrata (Fabricius) 

 except for the missing median elytral vitta, that I believed it merely 

 a color form until I dissected a male sent me from the British Museum. 

 This showed an aedeagus quite distinct from that of D. glabrata. 

 Besides lacking the median elytral vitta, the head is paler and the 

 breast not darkened as in glabrata. It clearly belongs to the glabrata 

 group, however.
