Life History. — Hectarthnun heros is a common 

 beetle in the forest thronghout many parts of India. 

 It is at times to be found swarming beneath the 

 bark of trees, and is evidently predaceous upon a 

 variety of species of insects. 



In company with the Trogositita beetle above 

 alluded to, I bred it out, in September 1901, from 

 Terminalia toinentosa logs from Seoni, in the Central 

 Provinces, which were badly infested by S. crassum, 

 the beetle being evidently predaceous upon the 

 Sinoxylon. Towards the end of April 1909, again, 

 I obtained the insect from a Tcyminalia chebula 

 tree felled a short time before, which was being 

 tunnelled into by the Sinoxylon. In this latter case 

 the Hcctarthrum beetles were ovipositing in the 

 tunnels of the Sinoxylon beetles, eggs quite unlike 

 those of the bostrychid being obtained. 



Sinoxylon anale, Lesne.
