6. Mydas annularis. 



Mydas annularis, Gerst. Stett. ent. Zeit. 1868, p. 100 \ 



Hab. Mexico *, Chilpancingo in Guerrero (H. H. Smith). 



A single male specimen, which I do not doubt is of this species. The band on the 

 posterior part of the second segment is broadly interrupted on each side by a black 

 spot. M. annularis, as well as M. militaris, Gerst., was not identified by Osten 

 Sacken in the earlier part of this work [antea, p. 73). * 



7. Mydas militaris.

Hab. United States, California 7 , Arizona 5 .— Mexico 1 2 , Venta de Zopilote nad 

 Iguala in Guerrero (H. H. Smith), Vera Cruz 4 . — Brazil 3 . 



I have already 5 called attention to the great variation of this species, and 

 I feel pretty confident that the above synonymy will be found to be correct. 

 If such is the case, Macquart's name rufiventris will have to be used ; the fact that 

 Loew adopted the same specific term for what he supposed to be a new species was 

 a coincidence only. 



s. Mydas quadrilineatus. 



Mydas quadrilineatus, Willist. Trans. Kans. Acad. Sci. xiv. p. 56 l . 



Hab. Mexico \ Tierra Colorada and La Venta in Guerrero (H. H. Smith), San Bias

Mydas crassipes, Westw. Arcana Ent. i. p. 51, t. 13. rig. 3 x . 



Hab. 1 North America 1 . — Mexico, Teapa in Tabasco (H. H. Smith). 



One male specimen, agreeing with Westwood's brief description, and differing from 

 M. decor in the details already given by Osten Sacken (antea, p. 71). The abdomen 

 is conical.
