DILUDIA.—SPHINX. 23 
83. Diludia lichenea. 
Macrosila lichenea, Walk. Cat. viii. p. 2047. 
Diludia lichenea, Butler, Trans. Z. 8. ix. p. 614°. 
Hab. Mexico, Cordova (Hége).—Braziu} 2. 
The Mexican example agrees well with the type in the British Museum. 
SPHINX. 
Sphinx, Linneus, Syst. Nat. i. 2, p. 796 (1766). 
Seventeen species are included in this genus, which is widely distributed over the globe. 
1. Sphinx leucophzata. 
Sphinz leucopheata, Clemens, Journ. Ac. Phil. 1859, p. 168'; Butl. Trans. Z. S. ix. p. 618”. 
Hab. Mexico *, Oaxaca (Hartwegq). 
I have not seen Clemens’s species; but, from the description, should judge it to be 
the same as S./ugens. This opinion is shared by Mr. H. Strecker, who says, in his ‘ Lepi- 
doptera Rhopalocera and Heterocera,’ that it is quite unknown to American entomologists. 
2. Sphinx lugens. 
Sphinx lugens, Walk. Cat. viii. p. 219°. 
Sphinzg andromede, Boisd. Lep. Guat. p. 74°. 
Hab. Mexico, near the city (Hége), Oaxaca! (Hartweg) ; British Honpuras 2. 
Mr. Butler says of this insect—“ Although coming from the same locality as the 
preceding, and very like it in its general characters, I believe this species to be quite 
distinct. It is altogether shorter, broader, and darker, and has the pale bars of secon- 
daries much narrower and whiter.’ I think it very doubtful whether Clemens’s species 
is distinct ; the specimens of S. dugens I have examined in the Oxford Museum vary to 
some extent. 
3. Sphinx justicie. 
Sphinz justicie, Walk. Cat. viii. p. 220°. 
Sphinx merops, Boisd. Lep. Guat. p. 73 ?. 
* Hab. Mexico”, Cordova (fiimeli); British Honpuras? ; Costa Rica, Irazu (Rogers) ; 
PanaMa, Chiriqui (22b0é ; Arcé, mus. D.).—Brazit, Rio }. 
This is a common species in Central America, but becomes scarce south of Panama. 
Through the kindness of Mons. C. Oberthiir I have had an opportunity of examining 
Boisduval’s type of S. merops,and find that it must without doubt be referred to S. justicia. 
4. Sphinx lanceolata. 
Sphinz lanceolata, Feld. Reise d. Nov. Lep. t. 78. f. 3°. 
Hab. Mexico!; Guatremaa }. 
I have never seen a specimen of this fine species.
