 Eudamus coyote Skinner, Can. Ent. xxiv, 164, 1892. 



Texas and Arizona. We have been confusing two species under this 

 name, but at present I am unable to correct the error with certainty. 



Genus CECROPTERUS Herrich-Schaffer

 Eudamus cellus Boisd. & Lee. 



Palpi larger than in Achalarus; second joint 

 oblique, roughly scaled; third porrect, moderate, 

 not concealed by vestiture of second. Antennae 

 about one-half as long as primaries; club slender, 

 tapering, bent near middle, with the apiculus 

 scarcely more slender than the basal portion. Pri- 

 maries similar to Achalarus 9 and Thoryhes ; cell 

 slightly over two-thirds as long as wing; recurrent 

 vein faint but indicated at base of vein 4 ; 5 slight- 

 rig. 9. Cecrop- ly nearer to 4 than to 6 ; discocellulars less oblique 

 Bd. and Lee. than in Achalarus, more as inThoryhes; costal fold

 Cellus resembles Thoryhes very closely in most of its struc- 

 tures, but I hardly think that the species belongs there. I do not 

 see anything to separate it from the genus Cecropterus, however, 

 and so am placing it for the present with the other species whose 

 banded primaries give them a close superficial resemblance. 

 Pseudocellus appears to be closer to Achalarus but I have not 

 had material for dissection and so prefer to leave it with cellus.
