 Mr. Waterhouse has brought for\Yard this species as 

 British, on the authority of two specimens (apparently 

 females) taken by himself, and which he has compared with 

 a male specimen of II . r a villa, Er., sent by Dr. Kraatz to 

 the British Museum, and also with a male of H. angusticollis 

 i-eceived by Mr. Crotch from Mr. Thomson, with the latter 

 of which they agree perfectly, except in the sexual character 

 of absence of emargination of the upper surface of the penul- 

 timate abdominal segment, the antennae in each especially 

 having the terminal joint only half as long again as that 

 immediately preceding it; in the male ^. ravilla however 

 (mentioned above) the terminal joint of the antennas is 

 almost tlu'ice the length of the preceding joint, and in this 

 respect it agrees with Erichson's characters for ravilla, in 

 other respects the specimens seem to agree. 



Dr. Schaum appears to have been under some difficulty 

 about these two species, since in his catalogue angusticolliSf 

 Thorns., is given as distinct (near H. clivisd), and afterwards 

 again appears as a synonym of ravilla (near j)alustris). 



The place of arigusticollis in our lists must be next after
