240 BRITISH ICHNEUMONS. {Erigorgus 



In Genera Insectorum, 1905, Szepligeti gives this species under both 

 Anovialon megarthrum, Ratz. Ichn. d. Forst. ii. 78 and A. simile, Szcpl. 

 Term. Fiiz. 1899, p. 214, admitting the synonymy but ignoring Grav.'s 

 priority. 



It occurs in Hungary, Sweden, Germany, etc., and is wide spread on 

 the Continent; where Krcichbaumer raised his forms from Arclia piir- 

 piirata and Parnassius Apollo respectively. It appears to have been 

 misunderstood in Britain, since Bridg. -Fitch give the parallel ncrvure 

 emanating above centre of brachial cell, and (perhaps consequently) 

 there is a lack of records. If not common, it is at least of broad distri- 

 bution with us for I possess it from Romsey in Hampshire (Buckell) ; 

 Deal in Kent during May, 1872 (Edward Saunders); Barmouth (W. Ellis); 

 as early as 10th April, 1909, Lady Robinson sent me a male from Clumber 

 near Worksop; and on 12th April, 1907, Charbonnier captured two or 

 three specimens of the same sex, one of which is referable to the var. 

 mdanops, at Cheddar in Somerset, and was much struck by their early 

 appearance, which I find nowhere noted.

The typical genus of the present Tribe consists of large and handsome 

 species of varied bright colours. It is easily recognised by the emission 

 of the second recurrent nervure distinctly beyond the submarginal or 

 intercubital nervure, by its face bearing no horn, though the frons in one 

 section is distinctly and finely cornute, by the emission of the first recur- 

 rent nervure from very far before centre of the cubital cell, by the glabrous 

 eyes, simple scutellum, and by the emission of the anal or parallel nervure 

 distinctly below the centre of the brachial cell, which is somewhat deter- 

 minately explanate towards its apex. 



It is quite necessary to add Gravenhorst's name to that of the author 

 of this genus, since Jurine included in it a curious medley of species of 

 all kinds of Tribes and even subfamilies. To the old authors this genus 

 represented what we nowadays consider a Tribe, and genera have from 

 time to time been split off as successive authors noted characteristics of 

 more or less generic value ; few corners are now left. Forster and more 

 recent writers have divided the present genus into Aphanistcs, but the 

 distinctions need not be considered generic in our fauna.
