from this area. Should it then appear that they are dis- 
tinct, the name mexicana Navas might be appropriate. 
The wing shape and markings are similar to those of mexi- 
cana; in the Apatzingan specimen the anal area in the fore 
wing is widened like Navas’ figure (Figure lb), but not to 
such a marked degree. The vertex and pronotal markings 
do not agree well with the figure.

Segura vitreus has long been considered a synonym of 
macer; the description fits well except “Abdomen $ cercis 
manifestis, cylindricis,” and “Abdomen longum, in $ alis 
longius . . characters which are not found in other 
species of Eremoleon or in related genera. Probably the 
type specimen, collected in 1871, has another abdomen 
affixed.

In all probability, this is E. macer; however, as mention- 
ed above, the figure shows a differently shaped CuP-f A 1 in 
the fore wing. According to the description, the wings are 
acute, and less prominently marked than in macer , there 
being only a small spot at the connection of CuP-f- Ai and 
CuA 2 , at the rhegma, and at the hypostigmatic cell. The 
hind wing is immaculate.
