ICHNEUMONID.E.— ALOMYA. 273 



dusky, remainder black; legs with the anterior coxse and trochanters and 

 femora black, more or less yellow at the apex, the posterior coxse wholly 

 black, trochanters black, with the tip yellow ; femora black, tarsi and tibiae 

 all yellow, the hinder pair of the latter black at the apex; wings smoky- 

 hyaline ; cellule 5-angular. 



The basal angles of the 4th segment are occasionally yellow, and the 2nd and 

 3rd have at times a black triangular spot on the middle of the margins. 



This and the preceding species closely resemble true Ichneumons, and were 

 it not for their comparatively gigantic bulk, much elevated scutellum, 

 &c. I should have placed them in that genus ; they exceed by 2 lines the 

 largest species of Ichneumon described by Gravenhorst, excepting Ic. lami- 

 natorius, which belongs to a section with black abdomen. 

 I possess one example from Francillon''s collection, a 2nd from 



Marsham's, and a 3rd from Haworth's; and Mr. Newman has 1 



taken by himself at Birch wood. 



Genus XLIX.— ALOMYA, Panzer. 



^n^ewTicE of the male setaceous^ porrect; of the female short, stout, filiform, 

 convoluted, with about 32 joints; head small, somewhat globose, seen from 

 above rather quadrate, the face with a slightly elevated tubercle: ei/es oval: 

 thorax somewhat cylindric-globose : scutellum 3-angular, flattish : wings 

 moderate ; cellule 5-angular : abdomen petiolated, convex, elongate, a little 

 dilated at the apex in the male, more so in the female : ovipositor concealed : 

 legs moderate, short, and rather thickened in the female: sexes dissimilarly 

 coloured. 



The chief characteristics of Alomya consist in the abdomen being 

 convex and petiolated, the head small and globose, and the cellule 

 large and 5-angular, not 3-angular, as stated in p. 126, from 

 Gravenhorst: the sexes are very dissimilar, and in the female 

 the wings are considerably abbreviated : the species are extremely 

 prone to vary, and I am of opinion that all the supposed indigenous 

 ones may be referrible to one species, notwithstanding their great 

 dissimilarity.
