WEST AFRICAN LEPIDOPTKRA. ()5 



DEVITZIA» eeii. iiov. 



Head small, slightly crested between antennae. Eyes of medium 

 size, prominent, without lashes. Palpi small, reaching only to the 

 middle of the front, densely clothed, the vestiture of the first joint 

 directed downward and of the second and third forward and upward 

 leaving apparently a wide notch between the first and second joints. 

 Antennae biciliate ; tongue very short, almost obsolete. Abdomen 

 of medium length, narrow, terete. Costa of primaries straight, 

 rounding at apex, apex acute, external margin nearly straight, in- 

 ternal margin slightly sinuate and produced at internal angle. Pos- 

 teriors subpyriform, margin entire, rounded outwardly and slightly 

 produced at extremity of the submedian vein. Vestiture of head 

 and thorax somewhat coarse and shaggy, the general coloration ashen 

 gray shading into pale brown. 



Note. — In the Mitth. des Miinchener Ent. Vereins for 1879, Dr. 

 Dewitz described and figured an aberrant Smerinthine form under 

 the name of Smeriathns Pechuelii. The type was a female ; since 

 then I have received specimens of a form closely allied to that de- 

 scribed and figured l)y Dr. Dewitz. I cannot, however, bring myself 

 to locate this insect with any sense of satisfaction in any of the 

 Smerinthine genera known to me, and, at the risk of animadversion 

 on the part of the " lumpers," I have resolved to set up a genus, to 

 which I refer the forms Pechuelii Dewitz and paapercula, mihi.

Upperpide. — Coloration uniformly ashen gray, lightest on ahdomen and internal 

 margin of secondaries, inclining to pearly gray on costa and outward margin of 

 primaries: a small reddish brown spot near the base of the primaries; discal dot 

 at end of cell gray, pupiled with dirty white; very indistinct zigzag discal and 

 median transverse lines; veins 3, 4, 5 and 6 each ornamented just before their 

 extremity by two minute patches of raised black scales; near the apex on the 

 costa is a triangular patch of pale brown, and on the inner margin just before 

 the internal angle is a subquadrate spot of darker brown. Fringe of primaries 

 checkered with dark gray on extremities of veins. 



Underside. — Uniformly lighter than upperside. Primaries and secondaries 

 crossed beyond middle by two exceedingly faint, zigzag, transverse lines, and a 

 series of minute black marginal dots on each vein. The fringe of the primaries 

 is darker on the underside than on the upper, and is faintly but regularly check- 

 ered with white on the intraneural spaces. The fringe of the secondaries is of 

 the same color as the adjacent parts of the wing and not checkered. 



* In honor of Dr. H. Dewitz, the Curator of the Zoological Museum of the 



University of Berlin, whose contributions to a knowledge of the African insect 

 fauna have recently been frequent and valuable.
