Remarks. — Coptotcrmes Jiongkonensis is a species closely agreeing 

 with C. travians (Haviland) and C. doboiiicus Oshima. However, it 

 differs from the former in the number of antennal joints and the 

 length of head in soldiers, and from the latter in the number of 

 antennal joints as well as in the degree of contraction of the middle 

 of submentum in the soldiers. Coptotcrmes Gestroi Wasmann (not of 

 Haviland) is still another nearly allied species, but the soldier has 

 broader head and the abdominal tergites are provided with a series 

 of spiny hairs along the posterior border.
