[Vol. 92 
Length of fore wing: 3. 4-4. 4 mm. First flagellomere: 3. 7-4.0 as 
long as deep at apex. Malar space: 0.80-0.85 as long as basal width 
of mandible. Temple: 0.36-0.51 as long as eye in dorsal view; 
rounded-off and strongly receding. Mesoscutum: notauli fine but 
definitely impressed, reaching 0.7-0. 8 the length of mesoscutum; 
surface shining, sometimes almost uniformly with coarse reticulate 
wrinkling and sometimes with brief smooth interspaces between 
many of the punctures, especially on lateral lobes. Mesopleuron: 
speculum smooth, polished, and swollen, peripherally with some 
coarse irregularly to sometimes rather regularly radiating wrinkles; 
surface otherwise on upper 0.5 complexly and moderately finely 
reticulately wrinkled (the wrinkling with some longitudinal bias) but 
on lower 0.5 becoming regularly puncto-reticulate. Propodeum: 
spiracle 1.3-1. 7 as long as wide; basal trans-carina sharp and high; 
apical trans-carina strong and complete, more or less irregular; cri- 
stae moderately projecting subligulate to ligulo-cuneate; median 
longitudinal carinae traceable but irregular, defining a very broad 
and narrow areola and the usual median apical area; surface, espe- 
cially on hind face, very coarsely and vermiculately reticulately 
wrinkled. First gastric tergite: postpetiole 1.8- 1.9 as wide apically as 
long from spiracle to apex; surface of postpetiole silky-shining with 
conspicuous delicate aciculation and with very large and sharp 
punctures of somewhat irregular distribution but in great part sub- 
adjacent to reticulately confluent; setae short and not or barely 
attaining the length of their interspaces; base of petiole with a rather 
strong and rounded lateral flange. Second gastric tergite: dully shin- 
ing with widespread fine aciculation and abundant, uniformly dis- 
tributed large and strong, subadjacent to a little reticulately 
confluent punctures; setae short, mostly equalling the length of their 
interspaces. 
Type Material. Holotype 9- ARGENTINA, Santiago del Es- 
tero Province, Los Tigres, in Malaise Trap, R. Golbach. Para- 
type: 1(5, same locality as holotype. Holotype in Florida State Col- 
lection of Arthropods; paratype in Collection of Charles C. Porter. 
Relationships. This distinctive and brightly colored Chromo- 
cryptus belongs to the same complex as C. huebrichi, C. prosopis, 
and C. tomsici. Most of its diagnostic characters are expounded in 
the key. Some other features of possible taxonomic importance are
