MR. &. D. HAVILAFD ON TERMITES. 393 



T. marginalis and T. nasufus. I describe here two new species 

 from Borneo ; the males are readily distinguished, but the 

 soldiers and workers seem almost identical. There are speci- 

 mens of soldiers and workers of other species, but in the absence 

 of the imago it is not right to describe them. 



Termes erevialattjs, n. sp. 



Female 8 mm. long, testaceous, wing-stumps fuliginous, an- 

 tennae pale. Head broadly ovate ; in profile the epistoma is seen 

 to project forward in the plane of the front of the head, beyond 

 the base of the labrum, which it overhangs. OcelH separated 

 from the small eyes by two diameters, and placed on a level with 

 their lower margin. There is a small foramen, from which a 

 shallow groove runs to the end of the epistoma. Antennae o£ 

 20 segments, the 3rd longer than the 2nd, the more distal 

 segments globose. Pronotum "9 mm. long, 1*6 mm. broadj 

 transversely oblong, the postero-lateral corners more rounded 

 than the antero-lateral ones. The posterior margins of the 

 mesonotum aud metanotum straight, not lobed. Anterior wing- 

 stumps much larger than the posterior, which they overlap at the 

 ■base. Wing 8'5 mm. long, 3 mm. broad, fuliginous, nearly 

 glabrous. The costal and subcostal nerves are well defined, the 

 median and submedian with their branches are but broad corru- 

 gations of the wing-membrane ; there is also an intervening 

 reticulation. The median is midway between the submedian 

 and subcostal, and has 3 or 4 branches, the first of which is about 

 the middle of the wing. The submedian has about 10 branches. 

 The hind legs exceed the abdomen. The abdomen is 2'4 mm. 

 broad. The ventral plate of the 7th segment has its pos- 

 terior margin very convex. The lateral cuticle of the abdomen 

 hairy. 



Soldiers : the larger 6 mm. long, head oehraceous, antennae, 

 thorax, and abdomen ochroleucous. Head 1'7 mm. long, 1'5 mm. 

 broad, subquadrate. Antennae of 17 segments, the 3rd subequal 

 to the 2nd, or of 16 segments, the 3rd longer than the 2ud. A 

 minute foramen above the epistoma, from which a groove runs 

 down to the apex of the labrum. Labrum oblong, obtuse, 

 reaching nearly to the middle of the mandibles. Mandibles 

 1*2 mm. long, the tip piercing, much incurved, especially that of 

 the right side, the cutting- margin with strong forward-pointed 

 teeth, two on the left mandible and one on the right. Gula
