hinder edge ; tibiae not spinose ; antennae fusiform and ending 

 in a small hook; forewings nearly entire, with a slight ex- 

 cavation at vein 2 ; all the characters show approximations 

 to the Smerinthinae and warrant this arrangement of the 

 family. 



Aiuyiitor. Hiibn. (Quadricornis Hair.) Soft brown 

 and whitish gray, approaching in its pale colors succeeding 

 genera ; forewings shaded with soft brown and crossed by 

 gatherings of triple brown lines; hind wings clay color, 

 shaded with brown; the fringes brown, cut with pale yellowish. 

 Larva with the granulated appearance of preceding group. 

 Common. Canada to Middle States. May to August, perhaps 

 usually double brooded in southerly localities. In Buffalo, 

 N. Y., larvae of the second brood failed to mature before 

 the cold came. 



Daremiua. Walk. 



Head small and sunken; antennae fusiform, with small 

 hook ; abdomen cylindrical and tapering, the segments armed 

 as in Ceratomia, tibiae not spinose. Larva without horns 

 on thoracic segments. 



Uiidulosa. Walk. (Ecpentinus Clem.). Gray, mixed 

 with yellowish scales ; forewings crossed by pairs of darker, 

 wavy or angulated lines ; hind wings darker, smoky brown, 

 with the fringes white cut with brown. Larva on lilac, ash 

 and privet. Not rare. Canada to Middle States. June 

 August. In the South are allied species: Hageni, Grote, 

 in Texas ; Catalpae, Boisd., in Georgia and Florida. The 

 tropical genus Syzygia, G. a. R., is related. 



IHliidia. G. a. R. 



Larger and stouter, with the thorax more produced 

 anteriorly; antennae fusiform, with slight terminal booklet; 

 abdomen cylindrical, the segments armed: wings entire, ex- 

 cavate above anal angle; rough gray species with darker 

 secondaries. Brontes of Drury, recognised by me from Cuba, 

 belongs here.
