hundreds of nests without them : they are most numerous during the 

 early summer months, whilst the larvae are in the nests, and I was at 

 one time inclined, from that circumstance, to think that the fluid ex- 

 tracted from them might serve to nurture particular sexes of ants, but 

 the fact of their not inhabiting every nest at once decides the question. 



The figure drawn is that of a male, as shown by the spined inter- 

 mediate legs ; some other minute differences may be observed between 

 the sexes, but not such as can be delineated in a drawing.

tra, much depressed towards the elytra, deeply foveolated in the cen- 

 tre, lateral margins reflexed : the legs are rather stout, each tarsus 

 3-jointed, but only observable under a high power, terminating with 

 a minute claw. The male has a minute tooth at the base of the in- 

 termediate femora, and also one towards the apex of the tibise. The 

 abdomen, in both sexes, appears to consist of five segments, united 

 above : the head, thorax and elytra with scattered yellow hairs, spar- 

 ingly so on the abdomen. The sexes are about equal in size. 



Note. — The Ciaviger has been subsequently captured even in great- 

 er numbers than by myself, in the same field at Mickleham, by Mr. 

 Samuel Stevens. Fred. Smith.

Note on the capture of Coleoptera in Lincolnshire, in June, 1843. I select the fol- 

 lowing from ahove a thousand specimens of Coleoptera, captured by me during last 

 June, in the north of Lincolnshire. The whole month, it will be remembered, was 

 most ungenial and discouraging to the entomologist ; and it may be well to add, that 

 in Lincolnshire, a succession of cold east winds were blowing without intermission for 

 nearly three weeks, and so unusual was the season, that for several nights together, in 

 the early part of the month, the thermometer was within a few degrees of the freezing 

 point.
