a few Observations in Mimicry. 9 
In the case of the species figured, attention should be 
drawn to the long thread-like antennae; the long black legs 
and the colouring and markings of the wings, which all 
suggest the Braconid, while on the wing one is deceived, 
without previous experience, by the very similar flight and 
attitudes. I myself caught the Braconid on a flower, 
where its ovipositor was concealed, thinking it was a species 
of the Syntomid genus Rhyncopyga. It is quite possible 
that this Braconid might be parasitic on the Rhyncopyga 
except that in size it is rather too large. 
Fig. 11 of Callopepla inachia 9, a Syntomid, with fig. Lla 
of Scea auriflamma, an Oenochromid, represents a remark- 
able and very interesting instance of convergence. As 
will be seen from the figures the two moths are very much 
alike in colouring and scheme of markings. The 2 Synto- 
mid must have been influenced by the Oenochromid, be- 
cause the ¢ of C. inachia is quite different, with a brilliant 
blue hind-wing and fore-wing, with red apical band and 
basal streaks. The 99 vary greatly from having a reddish 
orange band on fore-wing with orange basal streaks and 
hind-wing with shot-blue scaling at the base, to the form 
which is figured with an extension of a yellow band inwards 
to the base and the hind-wing with but a trace of blue 
scaling. The habits of these two insects are, however, 
quite divergent; the Syntomid flies briskly in the early 
morning sunshine and is fond of settling on various com- 
positae, such as Eupatorium and Ageratum, while S. 
auriflamma haunts shady woods and flies quite slowly. 
Both insects when at rest fold their wings flat over the 
abdomen, the Syntomid scarcely making the inner margins 
of the fore-wing meet, while the Oenochromid makes them 
meet closely. In relative abundance the S. awriflamma is 
by far the most abundant and is also more generally 
distributed. We found it on the Corcovado at 1,000 ft. 
at Rio, where C. inachia was absent. We also found it at 
Alto da Serra, where also C. inachia was absent. But at 
Castro and Fernandez Pinheiro we found both in the months 
of March and April, but always in their own special haunts. 
The last case of figs. 9 and 9a will have puzzled those 
who looked at the plate to see the resemblance. Fig. 9 is 
of the common Syntomid Paraethria triseriata, and 9a is 
of the Coleopteron Astylus antis. On March 11th, 1910, 
at Castro in S. Brazil, I came on a bush in flower which 
had myriads of the coleopteron flying round it. The sight
