OF INSULINDE, 19 
it under the-name compositus from North India and North 
Bengal. I saw in the British Museum a specimen collected 
by Dr. Horsfield in Java. | 
Probably this is still a different subspecies of the con- 
tinental form, but as the species also occurs nearly un- 
differentiated in Africa (clavicornis Latr.) it is better to decide 
this question with more material. 
Echthromyrmex orientalis Mac Lachlan. 
Mac Lachlan, Ann. Soc. Ent. Belg. XVI, p. 143 (1873). Moluccas. 
I saw the type in the collection de Sélys in Brussels and 
no doubt the mentioned locality is wrong, as there is in 
the same collection a quite similar specimen from Burmah. 
As the other species of this genus, E. platypterus Me. 
Lachl., is from Bagdad and as I saw an undescribed 
species from Ceylon in the British Museum, I presume that 
it does not extend so far as Insulinde. 
Genus Formicaleo Leach (1815). 
Leach, Edinburg Encycl. IX, p. 138 (1815). 
This genus has the tarsi analogous with Zomatares, but 
the spurs are much longer (as long as the four basal 
joints); the last joint is much longer. The antennae are 
longer than head and thorax together and clubbed at the 
apex. The wings are hyaline, spotted with some dark atoms, 
and about equal in length, long and narrow. Gonopoda of 
the o' short and the app. sup. valvular. 
This genus occurs in all parts of the world. In Insulinde 
it is represented by the following widely spread species: 
Formicaleo audax (Walker).

Myrmeleon audax Walker, Cat. Brit. Mus. Neur. p. 338, n°. 64 (1858). Nepaul. 
5 gravis Walker, 1. c. p. 339, n°. 65 (1853). Ceylon. 
vafer Walker, 1. c. p. 345, n°. 73 (1853). N. S. Wales.
