146 THE ENTOMOLOGIST S RECORD. o& 
from the intermittent buzz of Decticus or Locusta; a low trill on a 
deep note is just audible at close quarters; the noise is not loud, but 
penetrating and can be heard from a considerable distance. When 
performing, he raises his ample pronotum, the posterior portion of 
which acts as a sounding-board; the elytra are reduced to mere flaps, 
and are entirely covered by the pronotum when the animal is not 
chirping. It is interesting to note that the female has equally well 
developed stridulating apparatus ; I did not hear the female sing, but 
she uttered a short, deep exclamation of irritation when first handled, 
as the males do. 
The defensive yellow fluid mentioned above is ejected from the 
longitudinal folds which are situated on the metazona of the pronotum 
and on the tergites; the fluid is thrown to a distance of four or five 
inches. Similar glands occur on the tergites of some earwigs and are 
usually referred to as the “ pliciform tubercles”; their true function 
has not been noted, but they are usually regarded as stink-glands. 
Both in habits and general appearance there is a striking resem- 
blance between the Callimenidae and the Ephippigeridae; in both sub- 
families the elytra are highly specialised as musical instruments and 
both are round-headed, corpulent, sluggish creatures; both haye a 
characteristic song, and both swear when irritated; a still more 
striking analogy is that in both sexes the elytra are modified in the 
same way, and the female can chirp as well as the male; I know of no 
other group of Orthoptera in which this is the case. Writing in the 
field, away from books and libraries, I cannot remember the essential 
character on which the two sub-families are distinguished, but in 
Brunner’s system, at least, they are widely separated, the Callimenidae 
being placed first, before the Phaneropteridae, and the Ephippiyeridae 
nearly at the end; probably they are separated by a purely empirical 
character. The Callimenidae, or Bradyporidae as they are sometimes 
called, are a small sub-family with but two genera, the monomorphic 
Dinarchus, and Callimenis or Bradyporus, with about five species ; 
they occur almost throughout the Balkans, except the Dalmatian 
Coast, and extend to the north through Wallachia, Bessarabia, to 
South Russia and the Crimea, and on the south to north-eastern 
Persia, where Fernando Hscalera discovered a very handsome green 
and cream species. It is interesting to note that along the Dalmatian 
coast we have two species of Hphippigeridae, Ephippigera limbata, 
Kr., and F. sophacophila, Kr., the most easterly representatives of this 
extensive West Mediterranean eroup; I have taken both species as far 
south as the Bocche di Cattaro, and probably they extend a little 
further, they occur in Istria and around Trieste, and so have probably 
transgressed from Italy; thus, the areas of distribution of the two 
groups meet but do not overlap; I am inclined to think that the 
resemblance is due to actual relationship, and not to mere coincidence 
nor convergence.
