C. Iligginsi, ^, although having a close resemblance to the mem- 

 bers of the genus Sphenognathus, may be at once distinguished by the 

 slender sinuate and deflexed mandibles, characters in these organs 

 peculiar to the genus Chiasognathus. C. Iligginsi forms an appropriate 

 lint between the two genera. AV'e are indebted to C. Buckley, Esq., 

 for the discovery in Bolivia of this new species ; unfortunately, most 

 of the specimens sent (chiefly females) arrived in a very indifferent 

 condition. With reference to the females, although differing con- 

 spiciiously from the ^, both as to coloration and total absence of 

 even any trace of pubescence either on ihe upper or under surface of 

 the insect, tljcy may, nevertheless, I think, be united, without hesitation, 

 to the males, instances occurring in other allied species, showing, in 

 this respect, the same remarkable difference between the two sexes.
