ALLOTBIA CUBVICOBNIS. 245 



abscissa of radius. The second abscissa is but slightly curved ; cubitus 

 reaching to the middle. 

 Length 1^ If mm. 



Thomson's longicornis may be a different species. 

 He describes the legs and base of antennas as testaceous. 

 Hartig states that the cubitus is obsolete, while in the 

 species I have described it extends for more than half 

 the length of the wing. In the diagnosis (Germ. 

 Zeits., ii, p. 199) Hartig describes the legs as " pale 

 fuscous-red ; " in the table in vol. iii, 1. c., p. 350, as 

 " red." 



Common Clydesdale, Linlithgowshire, Dumfries- 

 shire. 



Grermany, Sweden. 



Hartig bred it from the galls of Nematus gallicola, 

 no doubt from an aphis which had entered the gall. 



11. ALLOTBIA CUBVIOOBNIS. 

 PL XVI, fig. 8. 



Allotria curvicornis, Cam., Trans. Ent. Soc., 1883, p. 366. 



Black ; the head inclining to piceous, the basal four or five joints of 

 the antennae fuscous ; mouth piceous ; legs dull testaceous ; the coxa3 

 and femora almost piceous at the base ; wings hyaline, nervures fuscous. 

 Antennae longer than the body, as long as the fore- wings ; the third 

 joint is slightly, and the fourth and fifth distinctly curved and a little 

 thickened ; the sixth is very slightly bent, but not so much as the 

 third. The radial cellule is of moderate length, wide, twice longer than 

 broad ; the second abscissa curved, a little more than twice the length 

 of the first. The cubitus only traced at the base. The pubescence on 

 the median segment is distinct ; the petiole piceous. 



Length If mm. 



Differs from A. longicornis in the much shorter 

 radial cellule, somewhat shorter antennae, these also 

 in longicornis <$ not having joints four to five curved. 



Rare. Glen Lyon, in July.
