WoKKEK.- — Same as in travians. 

 Collector's report : — 



Bombay, 15-3-1911. — Imagines. "Caught by lamplight in 

 -room." (Assmuth.) 



25-4-1911. — "Termites on footpath behind St. Xavier's 

 •College. Had probably been thrown on the road from one of the 

 neighbouring houses or gardens. . . ." (Assmuth.) 



20-8-1911— "From St. Mary's College, Bombay (Mazagon) 

 found in room in wooden shelves partly eaten up by termites, and 

 in garden in front of room in stump of tree. Unfortunately speci- 

 mens from both places mixed up together in same tube by the 

 Collector, Kev. Schurhammer ; but possibl}^ both parties belong to 

 the same species." (Assmuth.) — Both are, in fact, of the same 

 •species.

 TERMES SECTIOI^. 



Gen. ODONTOTERMES, Holmgr. 



Media of forewing arising from Cubitus. Third segment of 

 antenna3 shorter than second. 



Oclontotermes obesus, Ramb. 



Specimens from numerous colonies and nests are at hand. As 

 stated previously by Wasmann, the species varies rather consider- 

 ably in size, and also a little in appearance. At first I was in- 

 clined to assign the specimens sent to me to two different species ; 

 but a closer examination of the material seems to show that the 

 various forms are nothing but different biological types of the 

 same species ; for I have been able to insert between the tw^o 

 abovementioned forms an intermediary one containing qualities 

 of both. I propose to name these three forms Oclontotermes ohesus 

 <c, h and c. 



Odontotermes ohesus a : — Length of head of soldier 1*85-2 mm., 

 breadth of head about 1 mm., length of hodij about 37 mm. 

 Labrum reaching to one-half the length of mandibles. Salivarj^ 

 glands not ver}^ well developed. 



Odontotermes ohesus h: — Length of head (soldier) 1-96-2-03 mm., 

 breadth of head 1-11 mm. approximately, length of body 4-25-4-5
