Perv: Dep. Lima, reg. Alp. des Cord. à Casa Cancha, Pickering (Herb. Gray); Dep. 
Lima, Hacienda Arapa prope Yauli, ad Lima-Oroya viam ferream, 4400 m., Weber- 
bauer, 289 (Herb. Berol.: Pl. 29, figs. 15, 16). 
This species, originally collected on the U.S. Exploring Expedition, is of interest in 
having stiff stellate spines on the back of the vagina (Pl. 29. figs. 15, 16), which probably 
serve some protective function. This appears to be the only species in which some of 
the normal stellate hairs have been replaced or supplemented by stellate spines.
