Forficulidx and Chelisochide, families of Dermatoptera. 133 
leve, tuberculatum ; 2 magnum, subquadratum, integrum: pygi- 
dium ¢ parvum; ? parvum, vel longe productum ; forcipis brac- 
chia g brevia, incurva, robusta, valida, depressa, denticulata ; 9 
elongata, gracilia. 
The species which I include in this genus was included 
by Verhoeff in his genus Chelisochella, but as that is char- 
acterised by the long keel of the elytra, a feature which is 
wanting in this species, they cannot be ranged in that 
genus. The German author appears to have been un- 
familiar with the insects themselves, and assumed from the 
metallic colour and somewhat broad elytra that they fell 
in his genus. 
The type and only known species is Chelisoches shelford, 
Bure Ann + Mage Wnt (7),° vi, phe) Pl TV, figs 4: 
(1900.) (Sarawak.) (Ch. hercules, Burr, l.c. is the male.) 
Genus 9.—HAMAXAS,* nov. gen. 
Statura minore; colore nigro, rufo-variegato; antenne 16- 
segmentatee ; segmento 3 sat brevi, subconico; 4 + 5 tertium super- 
antibus, ovatis, 5 quam 4 longiori; ceteris subconicis, elongatis ; 
caput leeve, depressum, suturis vix perspicuis, margine postico 
truncato : pronotum quam caput zque latum, paullo longius quam 
latius, subovatum, margine antico lateribusque convexis, postico 
rotundato, postice haud dilatatum ; prozona vix tumida, sutura dis- 
tincta ; elytra minute punctulata, apice truncata, lata, carinula hume- 
rali brevissima, valde pubescentia ; ale similes : pedes breves, valde 
pubescentes ; tibize superne teretes, integres ; abdomen valde pubes- 
cens, sat depressum, parallelum, plicis lateralibus distinctis ; seg- 
mentum ultimum dorsale ¢ magnum, quadratum ; 9 angustatum : 
pygidium ¢ brevissimum, quadratum, transversum ; ? vix per- 
spicuum, subglobosum: forcipis bracchia ¢ depressa, sat valida, 
vix incurva, brevia, valde pubescentia, intus dentata ;|? subcontigua, 
recta, brevia, inermia. 
The species of the genus have always appeared quite 
unnaturally associated generically with Chelisoches morio ; 
the brown and black uniform, the small size, very hairy 
body, all point to a different group; but the general char- 
acters of Chelisoches are present, except that the pronotum 
is shorter and broader, and more ovate, not dilated pos- 
teriorly, and also the tibize are smooth above, and not 
depressed nor sulcate.
