where it is by no means uncommon, and it is really incredible that it 

 should be a native either of Clydesdale from which Cameron (Vol. IV) 

 records it, or of the locality given by Rudow for his gynandromorpha, 

 viz., the Harz. The record must certainly be due to some confusion 

 on Cameron's part between specimens sent to him by correspondents 

 from abroad and captures of his own. I shall therefore omit it from 

 my Tables. 



SYNOPTIC TABLE OF BEITISH TENTHRELOPSIS, ? ? . 



1. Apical margin of clypeus without a definite "excision" in its middle ; but 



it is often gently and evenly sinuated inwards throughout its whole 

 extent 2. 



— Clypeus with a definite excision in the middle which does not extend to the 

 extremities of its apical margin. (For this and other characters of our 

 only British species, cf. Ent. Mo. Mag., October,' 1912.).... excisa, Thorns. 



(= ornata, C, nee Lep.) 



2. Large forms (about 12 mm. long) with the hypopygium (N B) very large, 



prominent and deeply excised at its apex (just before the base of the 

 saw sheath). 2nd recru-rent n. interstitial with 2nd cubital n. Tegulse 

 and edge of pronotum black except in var. concolor. The group includes 

 many named varieties, differing greatly in colour among themselves, and 

 also (except var. concolor) from their very distinct and yellowish (white 

 and orange) male! (I have taken the latter paired with var. varia \)' 

 Formerly all were believed to be " good species." 



I possess British specimens of the following forms, and quote a few 

 where I have taken them — but no doubt most of them occur in all parti 

 islands. (The following List is a corrected version of that given 1 

 October, 1912, and should be substituted for it.) 



(a) Abdomen red to a large extent in the middle, black at base and 



apex var. nigronotata, Cam. (Types at S. Kensington) 



= thomsoni, Knw. (Taken in Warwickshire and 

 named by the author.) 



(6) Abdomen black at base only, red at apex. Legs red... 



varia, Gmel. (Surrey) 

 = cor data, C. 



(c) Like varia but legs black cordata, Oeoffr. (Surrey) 



= femoralis, C. 



(d) Abdomen all black, legs red... 



thoracica, Geoffr. (Surrey, Hants, Warwickshire) 

 = microcephala, C. 



(e) Like thoracica, but legs black caliginosa, Cam. (Surrey).
