soft and flexible to be effective defensive weapons ; whereas the joints 

 of the legs are often defended by powerful spikes ; the clubbed ends 

 borne by so many of these hairs are often hollow or cellular, and it 

 seems possible that they may be eventually found to be the seats of 

 some special sense (as hearing or smellj instead of being merely 

 protective. 



Summary. 



The results of the season's work may be summarized thus : forty- 

 four species have been found, of which I believe that only three or 

 four have been previously recorded in Britain. The total number 

 which rewarded Nicolet's admirable and prolonged search in France 

 was fifty-six. 



Of these forty- four species, I believe three to be entirely new 

 to science, viz. Nos. 21, 38, 39. 



Two species have, to my knowledge, been found in France, 

 Germany, and Sweden, viz. Nos. 2 and 32. 



Eighteen species in France and Germany, viz. Nos. 3, 5, 13, 

 15, 17, 22, 24, 25, 26, 27, 29, 31, 32, 33, 36, 40, 43, 44. 



Fourteen species in France only, viz. Nos. 1, 4, 6, 8, 10, 11, 

 12, 14, 16, 18, 23, 28, 41, 42. 



Six species in Germany only, viz. Nos. 9, 19, 20, 34, 35, 37. 

 I include Switzerland with Germany for this purpose. 



One species in France and Algeria, viz. No. 7 ; probably they 

 would have been found elsewhere if properly looked for, as two or 

 three have also been found in Sj^itzbergen. 



The life-history of two sorts, Tegeocranus latus and Nothrus 

 tlieleproctus, has been traced for the first time, and others confirmed, 

 in addition to the above observations on habits, &c. 



Part II. 



In this part the following rules have been observed : — 



Species which have been described by Nicolet are not redescribed, 

 but those given by Koch or others are described where the descrip- 

 tion of the author referred to does not seem to me sufficient for 

 certain identification. Species believed to be new are described. 



If there be fair grounds for believing that a species found by 

 me is identical with, or a slight variety of, one known by me to 

 have been already described, that species is adopted (defining it) 

 instead of giving a new name, although the former description may 

 not be sufficient for actual certainty. 



With regard to naming the joints of the legs, Bobin is followed, 

 not Nicolet ; this I have done, regarding Robin as the more eminent 

 anatomist as well as the more modern authority. It must be remem- 

 bered that their views are entirely different, c. g. the trochanter of
