There is some confusion existing in the references between the present insect and 

 the one following, but until some one carefully examines the specimens coming from 

 the various localities where Osmilice with hyaline wings occur no definite conclusion 

 can be formed. 



2. Osmilia tolteca, Sauss.

Hab. Mexico 123 , Presidio (Forrer), Dos Arroyos, Venta de Zopilote, Atoyac. Orizaba, 

 Teapa (H. H. Smith), Cordova (Edge), Valladolid, Yucatan 3 (Gaumer); British Hon-

In addition to the references given above, there are specimens of Osmilia at hand 

 from numerous other Mexican and Central-American localities. These either represent 

 two or more closely allied, or a single very variable, species. To j udge from Saussure's 

 description l (evidently of a male), most of these insects are larger, and they are more 

 robust and have broader tegmina than 0. flavolineata. It is also noticeable that in 

 these Mexican and Central-American examples the hind femora and tibiae are longer 

 and coarser than in 0. flavolineata. Many of them also have their tegmina con- 

 spicuously mottled with fuscous. 



3. Osmilia coelestis, Burm. 



Acridium coelestre, Burm. Handb. Ent. ii. 2, p. 634 (1838) l . 



Osmilia coelestis, Brunner, Proc. Zool. Soc. Lond. 1893, p. 606 * ; Bruner, Journ. N. York Ent. 

 Soc. xiv. p. 156 (1906) 3 . 

 Hab. Honduras 2 . — Brazil l 2 ; Peru 2 ; Trinidad 3 ; West Indies, Grenada 2 . 



I do not know how this insect differs from 0. violacea, Thunb. European authors, 

 however, have considered them distinct.
