 ergatoid females 16, triocellate workers 276 — Villa 36, VIII b 126, 

 VII 114 — , biocellate workers 17, uniocellate workers 8, macroergates 

 429, microergates 107. In the biocellate group 12 liave tlie posterior 

 ocelli, 3 liave the left posterior and tlie anterior, 2 liave the riglit 

 posterior and the anterior. In the uniocellate group 3 have the

 posterior. In addition to these one thousand specimens (taken from 

 upwards of twenty nests) two nests A and B, had been preserved 

 separately and contained 196 and 87 individuals respectively. A 

 contained the following : ergatoid 3, triocellate workers 36, biocellate 

 11, macroergates 44, microergates 12. B contained: males 6, ergatoid 

 4, triocellate 36, biocellate 3, uniocellate 1, macroergates 23, micro- 

 ergates 9. In the triocellate workers of nest A one has the large 

 scutellum, five have the small scutellum, and thirty have the escu- 

 tellate structure. Of the biocellate workers seven have the posterior 

 pair of ocelli, three have the riglit posterior and the anterior, one 

 has the left posterior and the anterior. In nest B one of the trio- 

 cellate workers has the large scutellum, eiglit have the small scu-
