Below I give a revised description of T. carrascoi, including diag- 
nosis of the previously unknown male. 
Female. Color: head, mesosoma and gaster metallic purple with 
more or less conspicuous blue reflections, gaster often almost 
wholly purple. 
First flagellomere: 4.0-4. 2 as long as deep at apex. Clypeus: 
almost flat, very low in profile, lower than in T. metallicus. Meso- 
pleuron: swollen area above along prepectal carina opposite specu- 
lum sometimes much invaded by fine punctures and wrinkles; other 
wrinkling often extensively irregular. First gastric tergite: 1.4- 1.7 as 
wide apically as long from spiracle to apex. Second gastric tergite: 
smooth and shining with micro-shagreening very weak to moder- 
ately well developed. Ovipositor: sheathed portion 0. 8-0.9 as long as 
fore wing; dorsal valve on tip conspicuously rippled; profile of dor- 
sal valve on tip a little concave over basal 0.5 but with a convex 
taper toward apex; tip 0.17-0.20 as high at notch as long from notch 
to apex. 
Male. Color: white flagellar annulus on segments 11 or 12 to 
16, 17, or 18; head and mesosoma sometimes mostly metallic blue; 
fore and mid femora orange with purplish metallic staining below 
and anteriorly; hind femur completely orange; tibiae orange; hind 
tarsomeres 3 (except near base) and 4 white. 
Length of fore wing: 9.6-11.3 mm. First flagellomere: 2. 5-3. 2 as 
long as deep at apex. Malar space: 0.6-0. 8 as long as basal width of 
mandible. Temple: 0.9-1. 1 as long as eye in dorsal view. Mesoscu- 
tum: punctures often dense throughout. Propodeum: cristae low 
and weakly projecting, broadly subcuneate; apical trans-carina 
detectable for a short distance anterio-mesad of cristae. First gastric 
tergite: 1. 1-1.3 as wide apically as long from spiracle to apex. 
Second gastric tergite: smooth and highly polished. 
New Specimens Examined. 6$ and 2$\ PERU, Lima Prov- 
ince, Matucana, 2389 m, 28-30-VI-1974, C. Porter, L. Stange, 4-5- 
VII-1976, C. Porter, C. Calmbacher; CHILE, Tarapaca Province, 
Chapiquina, 3370 m, 1-1977, Malaise Trap, C. Porter, G. Diaz. 
Relationships. Females of Trachysphyrus carrascoi may be 
distinguished from all other Coastal Desert congeners because of 
the strongly rippled surface and concave-convex profile of the dor- 
sal ovipositor valve between notch and apex. Otherwise, this species 
greatly resembles T. metallicus and often is hard to recognize from
