Alaudes alternata Fall, 1928

( Figs. 9E–F , 10 , 11C )

Diagnosis. Elytral vestiture erect, always much longer than twice width, feebly clavate except along the side margins, where these alternate with long, slender setae. Male genitalia unknown.

Material Examined. (Two specimens from three localities) – CALIFORNIA: Los Angeles Co.: Pomona , II-25-1895, Hubbard & Schwartz (1) USNM ; same data except II-18-1895 (1) OSUC .

Distribution. Only known from the type locality, Pomona in Los Angeles County, California.

Collection Data. None. Elevation range approximately 300 m.

Alaudes setigera Blaisdell, 1919 ( Figs. 2B , 9C–D , 10 , 11A )

Diagnosis. Lateral aspect of pronotum with short, clavate setae ( Fig. 9D ). Elytral setae slender and hair-like throughout, occasionally varying to feebly clavate-lanceolate, especially toward the sides and apex ( Fig. 9C ); setae uniform in length, vestiture always much longer than twice width, length of longest setae equal to or shorter than apical two antennomeres combined; punctures deep, well defined, distance between punctures about equal to size of puncture. Parameres ( Fig. 2B ) longer than basal piece; basal piece slightly broader than parameres, curved basally. Parameres gradually curved basally.

Variation. There is much variation in scale/seta size. In an Arizona series of specimens, the scales are more linear anteriorly and more scaly posteriorly. In a series from San Diego County, California near Warner’ s Springs, specimens have distinctly shorter and vaguely scale-like setae. In Kern County specimens, the basal elytral declivity is shallower and does not extend very far back, the basal pronotal declivity is less abrupt, broader, and not as long, and the setae are much more hair-like and elongate. In addition, the setae of the middle elytral elevation do not extend to the dorsal apex.

Distribution. Widespread in central and southern California, western Nevada, southern Arizona, northwestern New Mexico, and northern Sonora and Baja California in Mexico.

Collection Data. Some specimens were collected directly with ants in the genera Crematogaster Lund and Pheidole Westwood. Specimens were also berlesed or sifted from duff of manzanita, Ceanothus , oak, and pine. Collected in pitfall traps in the following habitats: Sand Wash- creosote-Paloverde, cheesebush and quail bush area, “in Joshua tree”, “at base of Opuntia parryi [Englmn.]”, “ Ephestia soil hibernac”, “hillside coastal sage scrub”, “Oak- Manzanita”, “Chaparral Scrub”, “sage brush”, “rocky hillside”, “on sand under cliffs with swallow nests”, “ Artemesia tridentata Nutt. ”, “ Atriplex [L.]- Franseria [= Ambrosia L.]”, bigcone Douglas fir, “moss under shrubs”, “ Rhamnus [L.] sp.”. Also found crawling on sand dunes at night. Elevation range 125–2,200 m.
