DERMAPTERA FROM JAVA, 29 
Family 2. Chelisochidae. 
Subfamily 1. Chelisochinae. 
20. Chelisoches morio Fabr. 
Wonosobo in May, Batavia in Jan., June, Aug., Oct. 
and Dec., Goenoeng Oengaran in June, and Semarang in 
Febr., March, May, July, Aug., Sept, Oct., Nov. and Dec., 
many specimens. 
This is an abundant and wide spread oriental species, 
21. Proreus simulans Stal. 
Semarang: January to November, and Batavia: October 
and December; several specimens. 
A common oriental species. 
22. Enkrates elegans Borm. 
Wonosobo: April and May 1909, 5 oo’, 6 QQ and 
19 nymph. 
These specimens all agree in coloration and structure 
with EH. elegans of de Bormans, except in one particular, 
and that is the pygidium of the male. In ME, elegans this 
organ is transverse, thick, with a gentle broad rounded 
emargination, the corner slightly produced to short blunt 
points. In one of these males the pygidium is typical, but 
in the other four it is different: it is broad, but the pos- 
terior margin is thickened, gently concave instead of convex, 
with a small, narrow median incision, and the angles are 
somewhat produced laterally, as the thickened margin 
protrudes beyond the sides. 
In other respects, the smooth head, transverse pronotum, 
and the coloration, these males are indistinguishable, and they 
are associated with the females with linguaeform pygidium, 
originally described by me as a distinct species under the 
name of Apterygida lingua (Termes. Fiiz. XXV, p. 486, pl. 
XX, fig. 8, 1902), and later definitely referred to EF. elegans 
(vide Burr, Ann. Mag. N. 4H. (8) III, p. 256, 1909),
