the British Museum specimen, the carton is glossy with clear secre- 
tion, but there are neither windows nor longitudinal ridges on the 
cell walls. A photograph (by C. K. Starr) of this nest in situ shows 
that the nest contained only or mostly eggs. If larger fraudulentus 
nests also have cells pointing opposite to the first row, they would be 
very similar to pelor nests. 
The closely related M. alienus (BMNH #216) and moralesi Wey- 
rauch (in the Museum of Comparative Zoology) hang a single verti- 
cal row of cells from a long pedicel, which is pale in color, contains 
little pulp and apparently incorporates air bubbles. The alienus 
specimen is a nest of eight cells, including a pupa 13 mm long, 
suspended from a 12 mm pedicel (Fig. 9). The moralesi specimen is 
similar but smaller; an 8 mm pedicel supports 6 cells of which 3 are 
pupae, one 12 mm long. Although this design is very different from 
those described above, these two species share with fraudulentus the 
longitudinal ridges on the cell walls and the glossy carton with 
windows. All four species described here apparently initiate pedicels
