lar gallery, which forms a narrow passage completely surrounding his 
body. Should, however, such soldiers find themselves in the open air, 
owing to an accidental breakage of their nest —- a position indisputably 
quite abnormal — they have only their feeble legs to keep themsel¬ 
ves in place, and when — for instinctive defence — they close their 
mandibles, the huge size of these levers, and the large amount of energy 
employed to move them, are the cause of an unavoidable change of 
place of the «engine» if this is not strongly fixed, which is not the case 
here; the soldier is thus involuntarily displaced. 
Termes (Eutermes) grallator n. sp. 
Soldier (nasute). The largest specimens 5 mm. long, head 2*1 mm. 
long, 1*4 mm. broad; smaller specimens 4*6 mm. long, head 1*9 mm. 
long, 1*2 mm. broad. Head almost black, 
shining; the rostrum often a little pa¬ 
ler, brownish. Abdomen greyish brown. 
Head rounded, rostrum very stout, co¬ 
nical, with broad base. The posterior 
part of the head is rounded and some¬ 
what elevated, making a curve with the 
rostrum which is nearly straight. Rudi¬ 
mentary mandibles visible. Antennæ 
long, of 13 segments, the 3rd more 
than twice as long as the 2nd, 4th 
shorter than the 3rd ; the four follow¬ 
ing segments a little longer than the 
4th, the five last decreasing, and more 
rounded at the apex. The antennæ are 
seldom apparently of 14 segments, 
the 3rd being more or less imperfectly 
divided in a basal segment nearly equal 
to the 2nd and a longer apical seg¬ 
ment. Pronotum saddle-shaped, the 
anterior lobe short, but little elevated. 
Legs very long, the posterior femora a little exceeding the abdomen. 
Abdomen ovoid, arched. Styli absent. 
Worker. About 5 mm. long. Head not so dark as in the soldier. 
Abdomen greyish-brown. Antennæ of 15 segments, shorter than in the 
soldier ; 3rd segment shorter than the 2nd, 4th nearly as long as, or 
a little longer than the 2nd. First mandible-tooth short, not larger than 
Fig. 4.
