slopes to the base of tho dypeus; clothed with a few moderately long, reddish 

 setae. Eyes situated behind the base of the antennae, very small, pale coloured. 

 Gula long and narrow, labriuu short auti broad (0.230 x 0.517) rounded in 

 front. Clypeus broad and very narrow, anterior border sliylitly sinuate. An- 

 tennae (Fig. 18) 13-jointed, 1st joint short and wide, narrowest in the middle, 

 2nd about half as long, widest in the middle, 3rd short and wide, shortest of 

 all, 4th and 5th short and wide, subequal, (ith narrow at base, widest beyond 

 the middle. Mandibles (Fig. 17) 1.032 long, each with two teeth, those of the 

 left mandible broad and blunt, those of tlie right more ])ointed. 



Pronotum reniform, a little wider than head, clothe(l scantily with moder- 

 ately large and small setae. 



Legs (Fig. ISJ) short and stout, with scanty short, fine, setae. Tibial spines 

 3:3:3. 



Abdomen long and narrow, segments with a scanty fringe of moderately 

 long and short setae. Cerci moderately long (0.423). Styli present in males. 



Meatiuremmts : 



Total length (aljout) 9.00. 



Head, from ba.se to apex of clypeus, long 2.35; from base to apex of 



mandibles, long 3.15; wide 1.457; deep 1.310. 

 Pronotum, long 0.752 ; wide 1.595. 

 Meso- and metanotum, wide 1.692. 

 Antennae (13-jointed) 1.786. 

 Tibia iii. 0.940. 

 Abdomen, wide 1.598. 



The soldiers vary soniewliat in size, the above measurements being those 

 of the majority. One example is only 5.25 long, with head and mandibles 2.440 

 in length, and 12-jointed antennae. 



The nympbae (first foim) in the type and other colonies are about 8.00 

 long and have 14-jointed antennae and unpigniented eyes. Tlie wing rudiments 

 are briglit orange yellow. 



Described from three colonies, taken in rotten logs on hill-side clad with 

 tropical scrub (22nd .June). The type colony comprised a king, queen, three 

 soldiers and about 200 nympbae (first fonn) and larvae. Another comprised 

 about 1000 larvae and nympbae, about 50 soliliers, three kings and three 

 queens. Another comprised about 400 larvae and nympliae and 15 soldiers, 

 but no imagos. 



Affinities. — The imago appears to be most closely related to Calotermes 

 (Ghiptnterm.es) triUneatwi Jfjob., from which it is distinguished, inter alin, by 

 its lighter colour, dark wing stumiis. smaller eyes and different head and prouotal 

 mea.surements. From Calotermes (Glyp.) brei-icornis Frogg. it is distirtguished 

 by its larger size (the former has a body length of 5.0 mm., as against 6.25 nun. 

 in the new species), at least one more joint in the antennae and fewer tibial 

 spines. The soldier castes of these two species dififer considerably in size.
