Hab. — India. In tbe British Museum. 



The S in the British Museum is from East India, the 

 ? from North India. 



The last insect I have to mention belongs to the genus 

 ChiasognatJtus, and should, perhaps, have been mentioned 

 first. The form of the mandibles, which, when viewed 

 laterally, somewhat resemble a small greek t, the granu- 

 lation of the elytra, and yellow colour, and the curiously 

 bowed middle tibiae, will serve to distinguish the (J, 

 whilst the evenly rounded sides of the thorax will separate 

 the ? from the other species of the genus.
