162 THE ENTOMOLOGIST’S RECORD. 
We will now consider the American species. One monotypic 
genus, Morsea, Scudd., is found in California, but the other groups, 
Episacti, Eumastaces, are essentially Neotropical. A good number of 
species are known, distributed through about half-a- dozen genera, but 
all are confined to the Neotropical region, extending from ‘Guatemala 
to Paraguay. They appear to be most numerous in the neighbour- 
hood of the Upper Amazons, in Peru and Ecuador. 
The last great group, the Thericleis is again essentially Ethiopian. 
About eight genera are known, all confined to tropical Africa, includ- 
ing Sokotra and Madagascar. Except Cymatopsygina flabelliferum, 
K., none are capable of flight, and many are totally apterous. Macro- 
mastav is found only in Madagascar, but the other Malagasy genera 
are well represented on the mainland. The only other group repre- 
sented in Africa is, as we have seen, the Choroetypi, and of that only 
two genera are peculiar to the region. 
To sum up, we find that (1) the Oriental region contains exclusively 
the Eructi, it has also the Gomphomastaces straggling into the Pale- 
arctic region, the Mrianthi straggling into the Australian region, and 
Choroetypt with two genera in the Ethiopian region. (2) The Neo- 
tropical region has a monopoly of the Hpisacti and the Humastaces, 
except one genus straggling into the Nearctic region, and no other 
Ewnastacidae are found in the New World. (8) The Ethiopian region 
has a monopoly of the Thericleis, and also has two genera and one odd 
species out of the typically Oriental group Choroetypi. 
Myrmecophilous Orthoptera. 
By H. Sr. J. K. DONISTHORPE, F.Z.S., F.E.S. 
According to Wasmann all the true myrmecophilous Orthoptera 
belong to the Gryllodea, though there may be some myrmecophilous 
species in the Phaneropteridae. Many species of DBlattodea, such as 
the North American Temnoptery deropeltiformis, Brunner, are found in 
the company of ants, but it is doubtful if they are truly myrmecophilous. 
The following is a list of the species that frequent ants’ nests. 
MyrMEcopHILa AcERVoRUM, Panz., is found in the adult state (fs 
and @s)in middle Europe with Mormica fusca, IF’. sanguinea, and I’. 
sanguinea with I’, fusca as slaves. It is also found with Lasius niyer, 
L. alienus and Myrmica laevinodis. The quite young larve have been 
found with Tetramoriwn caespitum. In south Europe and north Africa 
it has occurred with Aphaenogaster testaceopilosa, Camponotus lateralis 
and (’. dichrous. A variety occurs in India with Bothroponera suleata, 
where also the var. flavocincta, Wasm., is found with Playiolepis longipes. 
Mr. Burr calls attention to the fact (Mint. Record, 1899, p. 187), that 
Westwood recorded this insect from Netley, where it had been taken in 
moss, but that further evidence is necessary to confirm it as British. 
Myrmecoruita ocuracea, Fisch., is found in southern Europe and North 
America with Aphaenogaster barbara, and its very young larve with 
Pheidole pallidula. MyrMErcopuina sALomonis, Wasin., has been recorded 
with Monomorium salomonis from Tunis. MyrMeEcopHiILA PERGANDEI, 
Brun., occurs in Columbia in the adult state with Mormica fusca yar. 
subsericea, and also with F’. inteyra, I’. pallidefulcva, Camponotus 
marginatus and C. ielleus, and its larve at various stages with 
Cremastoyaster lineolata,and more seldom with Aphacnoyaster tenesseensis.
