species of parasitic Cynipidce. 367 



semicircular, not triangular, as is usual ; the reddish 

 head and piceous pleurae also distinguish it from A. 

 brevis. 



Hob. Mull, in June. 



Allotria solids, n. s. 



Black ; face, pleura, and base of abdomen piceous ; 

 antennae fuscous, the base testaceous ; legs testaceous ; 

 the four posterior coxae, the base of four anterior femora 

 and the greater part of posterior, light fuscous. Wings 

 hyaline ; radial cellule closed, double as long as broad ; 

 nervures pale yellow. Antennae a little longer than the 

 body ; 2nd joint thick, oval, a little more than one-half 

 the length of 3rd ; 4th a little longer than 2nd ; the 

 joints become gradually and slightly thicker towards the 

 apex. The scutellum, metathorax, and base of abdomen 

 are covered with a longish white pubescence ; the rest of 

 thorax and head sparsely pilose. Female. Length, 

 1 — 1|- mm. 



From A. minuta this species may be known by its 

 darker antennae and legs, longer radial cellule ; the latter 

 is a little shorter than it is in longicornis, and salicis 

 differs also from that species in its lighter-coloured legs, 

 much shorter antennae, and piceous thorax, it being also 

 a smaller species. In salicis there are two indistinct 

 sutures on the mesonotum, which, however, only extend 

 from the scutellum to the middle, and there is an 

 indistinct longitudinal suture on the lower side of meso- 

 pleura. It seems to belong to Foerster's genus Hemi- 

 crisis. 



Bred from a black Apltis on Salix pentandra from the 

 Kilpatrick Hills. 



Allotria piceomaadata, n. s. 



Head and thorax piceous ; abdomen black ; pleurae 

 dark ferruginous ; antennae black, base testaceous ; 

 legs yellow. The antennae are longer than the body, 

 not much thickened towards the apex ; 3rd joint nearly 

 double the length of 4th. Wings hyaline ; nervures 

 fuscous ; radial cellule open, double as long as broad ; 

 cubital nervure extending beyond the middle. Length, 

 1 mm.
