24 PROCEEDINGS OF THE 



This species is not very common. In Scotland I have taken 

 it in Eannoch, and I have seen English specimens taken by Mr 

 K. M'Lachlan and the Eev. T. A. Marshall. The larva has not 

 been described. It is stated by Kaltenbach to have been reared 

 from the stem of Anthriscus sylvestris, by Herr Boie of Kiel, and 

 from it was bred an ichneumon, Remiteles trichocampi^ Boie. 



5. Cladius Drewseni. 



Cladius Drewseni, Thorns., Hym. Scand,, i., 73-4. 



Black ; antennae a little longer than the body, very slightly 

 pilose ; the third joint a very little shorter than the fourth, and a 

 little curved beneath, the other joints getting gradually shorter 

 and thinner. Head covered with a grey pubescence, smooth, 

 shining; epistoma somewhat convex; on the front, directly above 

 the antennae, is a very distinct round depression, and below the 

 antennae are two comparatively large pits ; mandibles and apex 

 of labrum reddish; palpi pale. Thorax shining, pronotum minutely 

 punctured; tegulae black; cenchri oval, white. Abdomen broadest 

 in the middle, greyish pilose, apex especially; cerci short. AYings 

 sub-hyaline, costa pale, stigma fuscous ; second sub-marginal cellule 

 without a distinct horny point. Feet white, femora inclining to 

 yellow, marked with black in the middle, anterior coxae almost 

 wholly, posterior at base, and posterior tarsi at the apex, fuscous ; 

 claws and calcaria short. Length 2 J lines. 



Male with long pilose antennae, the knob at the base of the 

 third joint small. Femora with more black than in the female ; 

 anus testaceous! 



The colour of the feet separates this species from the rest of 

 the section. It is very like the white-footed variety of j^cidi, but 

 may be known from that species by the epistoma being convex, 

 instead of keeled, and by the shorter cerci and calcaria. In 2)(idi, 

 also, there is a distinct black dot in the second sub-marginal cellule, 

 which is absent in Drewseni. 



The larva is unknown. In Britain it has been found in 

 England and Scotland, but not very abundantly. On the Con- 

 tinent it is only known as a native of Sweden. 



C. Antennae in the male simple, compi'essed, without any process 

 on the thii'd joint. Cerci longish. Epistoma almost keeled. {Priophorus). 

 Apex of coxae and trochanters white — padi. 

 Coxae and trochanters black — Bridlaei.
