males alone. Male T. carrascoi have some white on the hind tarsus 
(no white in T. metallicus) and, in comparison to T. metallicus, 
show lower and weaker propodeal cristae and a shorter malar space. 
Variation. Some males of T. carrascoi have the mesoscutal 
punctation dense throughout but in others it becomes moderately 
sparse rearward. The less densely punctate specimens appear to be 
more common in north Chile, at the southern end of the species’ 
range. As does T. metallicus, both sexes of T. carrascoi evidence a 
north-south cline (from blue to purple) in ground color. 
Field Notes. This species occurs in the same natural and culti- 
vated high Andean habitats noted for T. metallicus. Like T. metal- 
licus, it occasionally enters Malaise Traps. 
3. Trachysphyrus agalma Porter, new species 
(Fig. 11,13) 
Female. Color: scape, pedicel, and (more dully) part of 1st and 
2nd flagellar segments metallic purple; 1st flagellomere white above 
near apex, 2nd flagellomere white above almost throughout, 3rd 
flagellomere white with a little brownish below at base; flagello- 
meres 4-7 almost pure white; 8th flagellomere white above (more 
narrowly so apicad) and black below; rest of flagellum black; head 
and mesosoma metallic purple with some dark blue reflections; gas- 
ter dark metallic blue with conspicuous purple staining, especially 
toward base; coxae, trochanters, and trochantelli metallic purple; 
front femur dull orange with purplish near base and throughout 
posteriorly; mid femur metallic purple, grading into dull orange on 
apical 0.3 anteriorly; hind femur metallic purple with orange irregu- 
larly on apical 0.5; tibiae orange with some metallic reflections; tarsi 
mostly dusky to blackish, becoming dull orangish brown basad on 
1st segments; wings moderately dark brown with blue reflections. 
Length of fore wing: 8.8 mm. First flagellomere: 3.2 as long as 
deep at apex. Clypeus : low and gently convex in profile, with high- 
est point near middle; apical margin straight. Malar space: 1.0 as 
long as basal width of mandible. Temple: 0.7 as long as eye in dorsal 
view; weakly and convexly receding. Mesoscutum: notauli sharp, 
not traceable much beyond basal 0.3 of mesoscutum; surface highly 
polished with numerous but mostly well separated, strong punc- 
tures; the punctures largest, densest and somewhat longitudinally 
slurred on central lobe, especially basad, but elsewhere contrastingly
