5 
as for holotype, and 5 workers from orchid plants (Cattleya 
bowringeana) shipped from San Jose, Guatemala and in- 
tercepted in U.S. Plant Quarantine at San Francisco, Cali- 
fornia (SF 20739 Supl. ; 46-5348). Deposited in USNM 
and MCZ. tl 2.14-2.49 mm., HL 0.51-0.59 mm., ML 0.28-0.32, 
WL 0.51-0.60, Cl 80-84, Ml 54-60. The Escuintla (type nest) 
series is made up of mostly smaller, yellow individuals, 
while that from San Jose contains workers mostly in the 
upper part of the size range given and medium ferrugineous 
or deep burnt-orange in color. Means of dimensions, but 
not of proportions, differ slightly, but there is also an 
absolute overlap. The color difference is not considered 
taxonomically significant in the face of similar variation 
seen in many other dacetine species. The name mixta re- 
fers to the intermediate characters, seemingly linking S. 
louisianae and S. emeryi Mann, but also distinguishing this 
species from both.
