 (Truqui 1 ). 



A single female example from Iguala, agreeing fairly well with Bellardi's description 

 of 0. truquii, and better still with Johnson's. I have seen Day's types in the Museum 

 of the University of Kansas.

 (H. H. Smith), Cuautla (Saussure 1 ). 



One female specimen from Teapa, agreeing with the descriptions, save in the 

 abdomen having a narrow yellowish-green margin, dilated angularly at the incisures. 

 A second example of the same sex, and from the same locality, has the eyes bare and 

 the black less extended on the femora.

Hab. Mexico 1 2 , Xucumanatlan in Guerrero 7000 feet (H. H. Smith). 



A single male specimen from Guerrero agreeing throughout with Bellardi's 

 description, save that the dilated spots of the abdomen are on the second and third 

 segments, instead of on the third and fourth ; the fourth and fifth segments have a 

 reddish-yellow margin (Bellardi gives the fifth only thus coloured). 



6. Odontomyia fratella, sp. n. 



2 .. Antenna? black, second joint about two-thirds the length of the first, the third not twice the length of the 

 first two joints together. Head narrower than the thorax ; eyes bare. Front black on the upper half
