CRABRO CARBON ARIUS, Daulb. : AN ADDITION TO THE BRITISH 



LIST. 



BT EDWARD SAUNDERS, P.L.S. 



Colonel Terbury, who has been very kindly collecting Rymeno- 

 ptera for me in Scotland during the past season, was fortunate enough 

 to secure a ^^ of the above species at Aviemore, it belongs to the 

 subgenus CosIocrairo,and may be easily distinguished from any of our 

 other species by the following characters : — 



Entirely coal-black, shining, with the exception of the 2ntl, and sometimes Srd 

 and 4.th joints, of the front tarsi, and the calcaria of the intermediate and hind 

 tibiae, which are pale whitish, the terminal joint of the antennae is also in the <? 

 diagonally truncate. Thorax shining, clearly punctured, and clothed with very short 

 black hairs, the propodeum very rugose, its area in both sexes well defined and 

 shining, but somewhat rugose, the crenatures surrounding it very strong ; the 

 mesopleursB each bear a very small tubercle, but this is less developed than in 

 palmipes and varius ; the intermediate and posterior legs are practically black, 

 although they may be more or less piceous about the tibiae and tarsi, and the inter- 

 mediate tarsi are often pale whitish. Long., 5^ — 6 mm. 

 A single J captured at Aviemore, June 2Sth, 1900. 

 The only other British species which have practically black legs, 

 and without yellow bases to the tibise, are leucosfomus and cetratus, 

 both of these, however, have the propodeum without a distinct area, 

 and so can be distinguished at a glance. 



Colonel Yerbury has found sevei-al other interesting species, but 

 I reserve a notice of these for a future number.

NABIS BREVIS, Scholtz : AN ADDITION TO THE BRITISH 

 HEMIPTERA. 



BT EDWARD SAUNDERS, F.L.S. 



I took a specimen of this species, originally described by Scholtz, 

 Ueb. Arb. Schles. Ges., f. Vaterl. Cultur., 1846, p. 112, last Saturday, 

 August 25th, by sweeping on low lying, somewhat marshy, ground, 

 along the canal between Byfleet and Weybridge. I have been on the 

 look out for it for many years, but it is so closely allied to our other 

 two small species that it might be easily, and possibly has been, mis- 

 taken for one or other of them. Its general characters agree so 

 closely with theirs, that I shall only point out the differences which 

 may be looked for to distinguish them apart. 



Brevis may be distinguished in both sexes from dorsalis, Leon Duf., and erice-
