ISOPTERA OF NEW GUINEA. 
369 
Antennæ long, of 21 segments, the 2nd longer than the 3rd which 
is short. Beyond the 5th the segments are longer and snbglobose. Epi- 
stoma not prominent. 
Pronotnm large, not quite as broad as the head with eyes ; the 
anterior margin concave, anterior corners rounded, postero- lateral mar¬ 
gins but little arched and converging, posterior border distinctly lohed. 
Posterior border of the mesonotum and metanotum obscurely concave. 
Anterior wing-stumps much larger than the posterior, and covering them 
at the base. 
Wings very hairy, the anterior ones 12*5 —14 mm. long, by 3’9— 
4*3 mm. broad. The base of the costal border and of the radius brownish. 
Mediana very faint, running nearer to the cubitus than to the radius, 
nearly straight, and reaching unbranched the apex of the wing (some¬ 
times with one offset). Cubitus very faint, with about 9—10 offsets. 
Male, with minute styli. 
New Guinea: Simbang (Huon Golf), September 1898. 
This species possesses the typical characters of the subgenus Covtd- 
termes, to which I have no doubt it belongs. It is remarkable for its 
large size. 
Termes (Eutermes) Bírói n. sp. 
Winged form. 6—7 mm. long. Castaneous above, the head and 
pronotum darker. Head oblong ovate, dark castaneous. Fenestra invisible. 
Eyes small, rounded. Ocelli small, separated from the eyes by more than 
a diameter. Antennæ of 14 segments, the 2nd longer than the 3rd which 
is very small, annular ; the following increasing towards the apex, sub- 
globose. Epistoma not lighter than the head, slightly prominent. Prono¬ 
tum not so broad as the head, anterior margin nearly straight, slightly 
everted; antero-lateral corners rounded, somewhat deflexed; postero¬ 
lateral margins converging into the narrow posterior margin which is 
obscurely concave. The mesonotum and metanotum narrowed behind, 
their posterior margins concave. Anterior wing-stumps a little larger than 
the posterior. Anterior wings 7—7*5 mm. long (without the stump), 
-2—2*1 mm. broad, umbrinous. Mediana faint, nearer to the cubitus than 
to the radius, reaching the apex of the wing, with one or two offsets. 
Cubitus faint, often reaching beyond the end of the posterior border, 
with about 11 offsets. 
Male with very minute styli. The abdomen of the queen 26 mm. long. 
Soldier. Length with mandibles 5*5—6*5 mm. Head 2 to 2*2 mm.
