Although most of the males of Cladiiis may easily be re- 

 cognised, the females are not readily distinguished from some 

 of the Nemati, N.pallipes St. Farg. for example, in which the 

 3rd submarginal cell receives a recurrent discoidal nervure 

 in the centre ; this submarginal cell, however, is the longest in 

 Nematus, and the 1st discoidal cell forms a less perfect triangle 

 than in Cladius; and although the 1st submarginal cell is in- 

 distinct in Cladius, it is altogether wanting in N. pallipes, 

 notwithstanding many of the Nemati have 4 submarginal cells. 

 Cladius was established by Latreille, in his " Considerations 

 Generales ", in 1810, and contains the following British spe- 

 cies : 



1. C. difformis Panz. 62. 10 mas. 



Found from the end of May to the middle of August in 

 Copenhagen Fields, Coombe-wood, on Blackheath, in Darent 

 Lane ; near Bristol ; Glanville's Wootton and Stafford Dorset, 

 J. C. Dale, Esq. ; Tynemouth Northumberland, G. Wailes, 

 Esq. 



Two or three years since my friend Mr. C. J. Thompson 

 gave me some larvae * that he found at Fulham on the under 

 side of the leaves of the China rose, eating small holes through 

 them : they were thickly clothed with short upright hairs, the 

 head was ochreous, with two minute black eyes : the body 

 green with a deeper line down each side and a darker one 

 along the back ; the anal feet did not assist them in walking. 

 They were full fed about the 28th of July, when they spun 

 cocoons amongst the leaves, and hatched the 1 1th and 12th of 

 August : one that was stung by an Ichneumon produced a 

 Tryphon the 20th of August. 



2. C. rufipes St. Farg. Mon. 58. 167. — Faim. Fran.pl. 12. 



/.5. 



3. C. Morio St. Farg. 58. 168. 

 Females beginning of July, Dover, J. C. 



4. C. pallipes St. Farg. 59. 169.— Faun. Fran.pl. 12./. 6. 



5. C. pilicornis Curt. Brit. Fnt.pl. 457 cJ. 



This insect, which I at first thought had only been the female 

 of C. diffbrmis, I found near London in June ; the specimens 

 which I consider to be the females of this species have simple 

 antennas, but longer than in C. difformis. 



6. C. immunis, and 7. C. luteicornis Ste. are undescribed. 

 The Plant is Vicia Cracca (Tufted Vetch).
