34 HYMENOPTERA. 



to Mr. Ingall for kindly communicating the above informa- 

 tion. Mr. Desvignes, we understand, has captured several 

 rare species of Ichneumonidce, but we have not been favoured 

 with their names. 



A winged female of Ponera contracta was captured by 

 Mr. Baly of Kentish Town, whilst reading by an open 

 window in his house ; the Ponera flew into the room and 

 settled on the page of his book. This insect is extremely 

 rare in this country; so much so, that, although I have 

 searched diligently for insects of the family to which it 

 belongs for many years, T never met with a single in-

 Ponera, attracted to pieces of meat laid in his garden as

Tachytes unicolor was captured in July on the sands 

 near Deal ; the only other localities for it known, are Luc- 

 combe Chine, Isle of Wight; W ey bridge ; and Sandhurst, 

 near the Military College. 



Miscophus spurius? Dahlb. This is one of the most 

 interesting discoveries which I have had the good fortune to 

 make. The genus Miscophus hitherto contained only a 

 single British species, and has always been accounted one of 

 extreme rarity; Mr. Westwood first discovered it in this 

 country at Coomb Wood, and subsequently both sexes were 

 taken by myself at Weybridge. In July last I met w T ith the 

 second species at Deal on the sand-hills. Like its congener 

 it is only to be found on the hottest summer days; when 

 cloudy or windy they disappear. Miscophus spurius differs 

 from M. bicolor in both sexes being entirely black ; the 

 metathorax is proportionably longer and has a central longi- 

 tudinal carina ; it is also a larger species. Dahlbom says, that
