distiphallus (more so than indicated 
by Steyskal, loc. cit.), and the 
anterior part of the ventral sclerites 
is slightly divided apically. A male 
and female of _P. coronata , of which 
the male is now designated as lecto- 
type, have been examined and this 
species (figs. 886, 887) is tentatively 
accepted as identical with the true C. 
jucunda . 
C. platyptera , which occurs commonly 
in California and Florida, was misiden- 
tified as C[. jucunda by Frick (1956: 
288) and by Spencer and Stegmaier 
(1973). The true distribution of the 
two species remains to be established 
either from larval leaf mines or from 
the examination of males, which will 
have been identified in the past as C. 
jucunda . 
C. menthae appears to be indistinguish- 
able from C. jucunda in external 
characters, and differences in the 
aedeagus of the two species are 
slight. In C. menthae (figs. 888, 
889) the base of the distiphallus is 
longer and the distiphallus itself is 
also slightly longer. In the limited 
material seen the discal cell is 
slightly smaller. However, it is not 
impossible that JC. menthae will prove 
to be synonymous with C. jucunda , but 
more reared material is necessary to 
decide whether the differences noted 
are of specific significance or within 
the range of variation of CL jucunda . 
Calycomyza menthae Spencer 
(Figs. 888-890) 
Calycomyza menthae Spencer, 1969a: 
152. Holotype male from Ontario in 
CNC. 
This species is known in the United 
States only from leaf mines on Hypt is 
mutabilis and Monarda punctata 
(Florida) and on Monardella sp. 
(California). The type series was 
reared from Mentha arvensis and 
Monarda f istulosa . The larva forms a 
large brownish blotch mine (fig. 890). 
The squamal fringe appears to be 
variable. If it is considered as 
pale, menthae will be separable 
from C, jucunda only by the male 
genitalia, and differences here are 
slight (see figs. 884-889). If it 
appears dark, menthae will be 
difficult to separate from the group 
of eight small species (couplets 
23-30), which can only be identified 
by the male genitalia.
