ART. 16 XEW TERMITES FROM INDIA SNYDER O 



than fourth, variable. Compound eye black, not round, separated 

 from lateral margin of head by a distance less than its long diam- 

 eter. Ocelli consistently absent. Postclypeus light yellow, bilobed, 

 bulging, over three times as wide as long. Pronotum of same color 

 as head, subcordate, not emarginate posteriorly but anterior margin 

 indented in middle, with dense, long bristles and shorter hairs, not 

 so long as wing scale (fig. 2). Mesonotum and metanotum convex, 

 projected beyond wing scale. Wings smoky, margins ciliate, tissue 

 I)iinctatc, hairs on surface. Median vein running nearer to middle 

 of wing but closer to cubitus than subcosta, cubitus and branches 

 taking up small area of wing. Abdomen with dense hairs, a row 

 of longer bristles at base of each tergite. 



Compared with cotype material of H. indicola and ceyloniciis 

 Holmgren, in cases of both winged and soldier castes: Fewer seg- 

 ments to antennae, and smaller eyes, which are farther from lateral 

 margin of head than in indicola; closer to ceylonlcus but fewer seg- 

 ments to antennae, third segment of anten- 

 nae shorter than second, ocelli consistently 

 absent, wings darker. 



Measurements. — Length of entire winged 

 adult, 9.5-9.75 mm; length of dealated 

 adult, 5 mm; length of head (posterior to . ^v— v- 



tip of labrum), 1.2 mm; leng-th of prono- ^

length of anterior wing, 7.55 mm; leng-th of Dorsal view of pronotum 



wing scale, 0.65 mm; width of head (at 



eyes), 0.8 mm; long diameter of eye, 0.2 mm; width of pronotum. 0.7 



mm; width of anterior wing, 1.9 mm. 



Soldier. — Head light yellow-brown, with scattered long bristles 

 and shorter hairs. Antennae light yellow, 12 to 14 segments, third 

 segment shorter than second. Gula over twice as wide at front as at 

 narrowest point in middle. Pronotum emarginate anteriorly, nearly 

 straight posteriorly. 



In ceylonious, the gula is proportionally wider at middle, and 

 normally there are more segments to the antennae than in mula- 

 haricus; also the head and pronotum have sparser long bristles. In 

 malaharicus the pronotum is distinct in both size and shape (fig. 2). 



Measurements. — Length of entire soldier, 4.6 mm; length of head 

 with mandibles, 2.4-2.5 mm; length of head without mandibles, 1.5 

 mm ; length of left mandible, 0.9 mm ; length of pronotum, 0.4 mm ; 

 length of hind tibia, 0.65 mm; width of head, 0.8-0.85 mm; width of 

 pronotum, 0,6-0.65 mm. 



Tyye locality. — S. Mangalore 400 feet, Malabar coast, Madras, 

 India.
