It is from PERU: [Hiudiuco]: east side of Carpish Moun- tains, 74 km southwest of Tingo Maria, 2800 m, 17 Oct. 1954 (E. I. Schlinger, F. S. Ross, San Francisco). Three other males from Peru (one without the metasoma) differ from the above description in the fol- lowing parhculars: Thorax less shining, scutum and scutel- lum with slightly smaller punctures, mostly separated by less than a puncture width of ground distinctly dulled by microsculpturing. Inner crest of hind tibia ending in flat, rounded projection that is narrower than that of Colom- bian Cliilicola brzoskni. Bosses or protuberances of S2 bluntly right angular in lateral view, height over half of basal wicith (in C\)lombian specimens, they are rounded, height less than half of basal width). Ventral apicolateral lobe of S7 with basal piece slightly broader than in Colombian C. brzoskni. Both the pimctation and the inner hind tibial crest vary among Colombian specimens, although not reach- ing the states described above. 1 tentatively consider these specimens to be variants of C. brzoskai. Tlie localitv data are as follows: PERU: [jiiniii]:
