Desmopachria granum Lee. The reference of this

 Cabo. 



Hydaticus bimarginatus Say. Florida, Texas. San 

 Jose del Cabo.

The specimens from this region have the punctures of 

 the striae two to five well marked, but as there is a notable 

 variation in the specimens from the Atlantic region, I 

 cannot think that the present forms represent a distinct 

 species.
