Pleoiifctyptera siikflsiTMlalis Grt. 



1881. Grote, Papilio, i, 1G6, 2Iegachyla. 



1893. Smith, Bull 44, U. S. Nat Mus., 363, Pleonectypiera. 

 Ground color creamy gray, with a more yellowish tinge in primaries. Median 

 lines incepted from trigonate blackish spots. T. a. line outwardly oblique, with 

 a slight incurve, consisting of a paler inner and a darker, smoky and yellow 

 outer portion, the latter out of the costal spot. T. p. line with an even out and 

 equal or greater incurve; consisting of a pale inner portion, which is emphasized 

 by the costal spot and a darker, olivaceous outer portion which tends to shade 

 into the s. t. space, which darkens as it approaches the inner margin and at the 

 s. t. line. S. t. line distinct, irregularly denticulate, with paler scales following 

 the sharp dark edge. A series of small blackish terminal dots. Eeniform dusky, 

 obscure, lunate, not defined. Secondaries yellowish at base and to a dark outer 

 shade line, beyond whicli the outer border is darker. Beneath : yellowish, 

 ranging from almost immaculate to a powdery reddish on which the maculation 

 of upper side is vaguely reproduced. Expands .92-1 inch. = 23-25 mm. 



Hab. — Southern Arizona, in May ; Clareinont, California, with- 

 out date; Los Angeles Co., California. 



The type is in the Neumoegen collection, and I have a good com- 

 pared pair before me at present. The maculation is almost exactly 

 like incusalis in t. a. line ; but the t. p. line is not angulate and the 

 reuiform is obvious. From jinitima it is distinct by the course of 

 the t. a. line and by the lack of powdering on the primaries. With 

 the male at hand discrimination is easy, because it lacks the wing 

 and abdominal -tufts of incusalis, while it differs fi^m that and 

 finitima as well by having single longer cilia on each side of each 

 antennal joint. The species occurs within the range of both those 

 with which I have compared it, and it is not improbable that exam- 

 ples are mixed in collections with one or both. It is quite easy to 

 lose a female in either series. 



Fleoiie<^tyi>lera Iiistorialis Grt. 



1882. Grt., Can. Ent., xiv, 188, Pleonectypiera. 



Ground color pale leather-brown over luteous. Palpi darker brown at sides. 

 Primaries with reniform black, contrasting, of good size, kidney shaped, margins 

 not defined. Median lines quite distinct. T. a. line upright or a little oblique, 

 rigid, consisting of a narrow yellow inner and an equally narrow outer blackish 

 or brown line, the latter from a somewhat enlarged spot on costa. T. p. line only 

 a little sinuate, even, composed of an inner dark line from an enlarged costal 

 spot, and an outer yellowish line; neither very clean cut or contrasting. S. t. 

 line very obscure, marked by a darker s. t. cloud and somewhat irregular. A 

 series of obscure brown terminal lunules. Secondaries pale yellowish or smoky 

 at base, becoming brown toward the outer margin beyond an extra-median dusky 

 line. Beneath : tending to brick-red, powdery, more yellowish at base and along 

 inner margin. E.^pands 1.05-1.12 inciies ^ 26-28 mm.
