c??. Tongue very weak and slidrt. Paljins small in ?, larger in <?. Abdomen 

 spinose all over dorsally, the spines very weak, dense at and near the apical edges 

 of the segments ; no broad under-scales on the tergites. Eetinacnlnm absent ; 

 frenulum reduced, the bristle of c? short bnt rather stent, the bristles of ? thin, 

 Ijair-l'ke. Pnlvillns and jjaronycliinm ])resent. Tibiae not spinose ; anterior tibia 

 with or without apical tliorn ; one pair of sjmrs to hindtibia. Hindwing red for the 

 greater part. 



(?. Antenna more distinctly dilated laterad than in At?torp/ta, sometimes snb- 

 jiectinate, or even pectinate. Tenth abdominal tergite ronnded at end, or feebly 

 sinuate (caecus); sternite triangnlar, simple. Harpe simple, rounded or obtusely 

 ])ointed at end, not divided as in Ai/iorp/ia. Penis-sheath with one or two conical 

 teeth at end, pointing laterad. 



?. Antenna (PI. LX. f. 14—17) with traces of the lateral expansions oft?. 

 Vaginal plate membranaceous, without a distinct ridge in front of the vaginal cavity, 

 or the ridge is more or less wrinkled, not strongly chitinised. 



Larva granulose, head triangnlar ; horn tuberculated ; green, with white or 

 yellowish side-bands, often spotted with red. — Food-plants : Pojjiitus, Prun/ts, 

 Salix, and other trees. 



Pupa stout, more or less rugulose and punctured, somewhat glossy, sheath of 

 antennae rather broad in both sexes. 



Ildb. Palaearctic and Nearctic Regions. 



Six species. 



According to what we have said in the introduction, the type of Spliiit.v is 

 ocdlatd. Synonymous with Sphinx are the generic names Laotlioii, Dilinu, and 

 Paoiiid.H, which have all ocellatn for types. The Grotean genus Eusmerinthus, 

 reduced to the rank of a subgenus by its author in 1886, is based upon one Nearctic 

 sjtecies {jamaicensis) which differs in the (? -antenna from all the allied forms, and 

 on 8ome Palaearctic species which are not very nearly related to jamaicensis. There 

 is some reason to separate jamaicensis from the other species, and we should not 

 reject lliismerinthns as a genus if there was a character, apart from colour, by 

 wiiich the ? could be distinguished. This jamaicensis is, in the development of the 

 J-antenna, the highest si)ecies, the long pectinations being an exaggeration of the 

 short side-processes or feeble dilatations found in the other members of the genus 

 Sphinx.
