lower rank in the Family. Xo generic separation of the European 

 species of Smerinthus is made by Wallengren, but such is evidently 

 demanded. Although the European Smerintlms tiliae is enumer- 

 ated first by Latreille under his genus, yet it cannot be considered 

 his type while he cites oceUafus under the same name, and which 

 latter species we have separated as typical of the genus in our Cata- 

 logue. Laothoe Fair, and Delina Dalman, appear to be cast for the 

 same species, and to be in reality, intended as = Smerinthiis Latr. 

 The former has been used for the European poipidl, and we have 

 considered this species as the type. Nor does this arrangement in- 

 terfere in the slightest with Hiibner's Verzeichniss, a work to which 

 we would accord the fullest authority and weight. We liave 

 taken for Hiibner's genus Paonias the type P. excaecatus, which 

 (with Myops and Salicis) he includes on p. 143. This genus is (ex- 

 cluding Salicis as the type of Smerinthus) unrepresented in Europe, 

 and contains two, if not three, American species. Calasymbolus, 

 Grote, is also unrepresented in Europe ; its type, Astylus, is not 

 mentioned by Hiibner. For the European tiliae, Hiibner's genus 

 Mimas must be retained ; there are no described American species. 

 We have already proposed to restrict Polyptychus Huhner, to 

 Cramers doitatus as the type. Quite distinct from any of the other 

 species included under Polyptychus and more strongly marked, 

 perhaps, than any of the other Smerinthoid species, the American 

 juglamlis has already been separated under Cressonia. 



Wallengren, unhappily (and unnecessarily), refers Philampelus, 

 Harris, as a synonym to Choerocampa. The proper type of this 

 genus is Pliilampelus satellitia, Harris (nee Linn.), Daplmis Pan- 

 dorus Hiibner; the genus is unrepresented in Europe. Wallengren's 

 idea is probably taken from Burmeister's fusion of the genera in the 

 *' Sphingidae Brasiliens." Nor does Wallengren separate D. nerii, 

 as the type of Daphnis Hubnev, as has been correctly done by Curtis. 

 Quite unnecessarily, Wallengren erects a new genus for the Euro- 

 pean Macroglossum stellatarum, already originally considered as the 

 type of Scopoli's genus. Wallengren has, evidently, taken the pre- 

 valent European idea of " Macroglossa," without exercising literary 

 research. For Hemaris Dalman (to which Boisduval has referred 

 S. fuciformis as the type), Wallengren uses the incorrectly written 

 term " Macroglossa."
