Head rotund, smooth, shining; thorax: anterior margin raised in 

 a ridge which is produced at each side into a straight nearly upright 

 spine ; sides and median line low carinate ; humeral angles and end 

 of median carina slightly prominent ; scutellum with a long, curved 

 slightly retrorse spine ; elytra entirely hyaline without spines ; ostiolar 

 canal rather strongly curved posteriorly then anteriorly near apex, 

 which from above appears as a short, abruptly pointed tubercle. Poor 

 condition of material prevents descriptions of beak and rostral sulcus.

Uhler's description of this species in two different genera in suc- 

 cessive years is hard to understand. Notwithstanding his later as- 

 signment of the species to the genus Metacanthus, supported by simi- 

 lar action by Distant, if we can rely on Fieber's description 6 of that 

 genus, this species does not belong to it. I have been unable to con- 

 sult the original description of Metacanthus by Costa. 7 



To the generic description it need only be added that this species 

 is stramineous in general color, most of the head, and terminal an- 

 tennal joints being black, and the femora spotted, the tibiae banded 

 and the tarsi tipped with fuscous to black. Length 4 mm. 



Occurs in southern Florida.
