 Ulidia fulvifrons. 



Nigro-piceo-nitens, hypostomate nigro; fronte, oculis, anten- 

 nisque fulvis, occipite brunnea ; thorace nigro-nitente ; abdomine 

 nigro-piceo ; pedibus fulvis ; anticis, cruribus antice brunnescen- 

 tibus ; tibiis tarsisque brunneis ; intermediis posticisque, femori- 

 bus basi, brunneis; tibiis postice brunneis; alis hyalinis ; costa 

 brunnea, punctoque apicali nigro. — Long. 4 mill. 



[This species may belong to the Ulidina, but it is not probable 

 that it is a true Ulidia. The Ulidia metallica Bigot, described 

 in the same place, is not an Ortalida at all, but belongs to the 

 Agromyzidse, perhaps to the genus Agromyza. — Loew.~]
