3U6 Catalogue of North Amm-ican Sphinges. 



dorsal series of white dots on the abdomen ; in other respects it 

 seems nearly allied to the Chamn.nerii. When my Catalognes of 

 the Insects of Massachusetts were pnblished I was not aware that 

 the specific name Epilobii had been previously ai)i)ro[)riated ; for 

 the species to which I then applied it I have now substituted 

 that of Chamanerii derived from Tournefort's name for the genus 

 Epilobium.

Ash-gray ; wings angularly indented ; first pair with two dusky 

 bands near the base, connected on the inner margin by a blackish 

 line, a few undulated and zigzag transverse lines beyond the mid- 

 dle, a dusky outer margin, a half-oval brown spot at tip, and a 

 small deep brown patch including a white I near the tip; hind- 

 wings reddish gray, with a dusky hind-margin ; collar edged 

 with brown ; abdomen with two dorsal series of black dots. Ex- 

 pands two inches. Inhabits Indiana. 



Of this species I have seen only two individuals, both females, 

 having rather long slender and simple antennse, attenuated and 

 curved so as to form a hook at the end. In the shape of the 

 wings and distribution of the colors this insect nearly resembles 

 some species of Smerinthiis, from which genus it is excluded by 

 the length of the tongue, which nearly equals that of the body. 

 Pterogon Guunc, which I suppose to be the only legitimate .spe- 

 cies of the genus that has yet been discovered in the United 

 States, is known to me only by Mr. Abbot's figure. 



Genus VIII. Thykeus. Swainson.

 Brown ; wings sinuated and slightly angulated on the outer 

 edge ; first pair with an oblique streak and an eye-like dot before
