This is a very interesting species and possibly throws some 

 light on Walker's Florida and Massachusetts records, for Mydas 

 isopterus Wied. = Dolichogaster hrevicornis Wied. 



It seems strange that after so many years and with the amount 

 of collecting that has been done, that something bearing on this 

 record should not have been found. 



Minus antennae the species described could on venation and 

 color be readily confounded with D. hrevicornis. The venation of 

 Dolichogasier as figured by Williston (Manual page 190) does not 

 agree with the type of the genus D. hrevicornis as figured by Wied- 

 man (Mon. Gen. Midarum, pi. 53, fig. 9).
