medial welt extending about two-thirds of length; T-III with strong 
medial carina extending through pit row, pit row only slightly 
depressed, pits subequal in size to punctures but deeper, apical teeth 
clustered medially. Head blue, except face greenish blue; thorax 
purplish blue, abdomen greenish blue; scape, pedicel, F-I and part 
of F-II blue, rest of flagellum yellowish red except apical segment 
brown. 
Female. Body length 6-7 mm. Same as male, except scapal basin 
without silvery setae; antenna blackish; F-I 2.2 times as long as 
wide; F-II length 1 .7 times width; F-III 1 .4 times as long as wide, and 
T-V with fine apical ridges. 
Holotype male: CHILE, Atacama Prov., 40-60 km s Copaipo, 
18-20 October 1969, L. E. Pena (davis). Paratypes, five males, two 
females: CHILE, Atacama Prov.: two males, one female: same data 
as type; one male, one female: 26 mi s Copaipo, 19 October 1969; 
one male: 14 km s Vallenar, 13 October 1969; Canto del Agua, 21 
October 1969; one male: La Junta, 15 October 1969. 
Discussion. Although very closely related to chilicola, atacamae 
differes in the strongly convex lateral margin of T-III and the yel- 
lowish male flagellum. Both species have a finely cross-ridged scapal 
basin, a characteristic not found in other Pleurochrysis. 
Pleurochrysis simulator Kimsey, new species

pletely clothed in silvery setae, somewhat sparser medially; brow

swelling slight, pit row slightly sunken, pits large and deep. Body
