Abdomen and sternum granulate, the granulations being more 

 prominent on the basal joints of the abdomen. 



A single male was collected at Plantation Key, from which I 

 derive the following measurements: Length, 14.2 mm.; breadth, 

 21 mm.; ratio, 100 : 148. This species is readily separated from 

 all other North American species by the spines on the anterolateral 

 teeth.
