EVANIID.E. PAXYLOMA. 119 



compressed;, inserted by a long slender peduncle below the scutellum : ovi- 

 positor not exserted : legs moderate : tibice not clavate, with a pair of spurs 

 at the apex. 



These minute insects, at a first glance, resemble some of the Chal- 

 cidae, from the paucity of nervures in their anterior wings, their short 

 antennae, and petiolated abdomen : from the true Evania3 they may 

 be known by the antennae being faintly thickened towards the apex, 

 and by having the 3rd joint scarcely longer than the 2nd, as well as 

 the anterior wings being destitute of discoidal areolets : the indigenous 

 species are probably parasitic upon the insects of the genus Ectobius, 

 and as this last genus is rather numerous, there are probably many 

 species, but, as yet, 2 only have been detected.

 Black, shining, coarsely punctured ; head, trunk, and petiole with a slightly 



hoary pubescence ; abdomen glabrous, smooth, glossy ; legs black, anterior 



pair slightly pitchy in front. 



My specimen of this insect was taken by Mr. Dale, who finds this 

 species on Parley Heath in September.

 Ev. fulvipes. Curtis, v. vi. pi 257.— Steph. Catal. 343. No. 4005. 

 " Black, shining, variolous ; antennae rather thickened towards the apex ; head, 



trunk, and petiole pubescent, the femora transverse-globose; abdomen 



ovate, very shining; four anterior legs with the apex of the thighs, the 



tibiae and tarsi fulvous." — Curtis, I. c. 



Taken near Dorchester, and near Heron Court, Hants, in August. 



Genus XXXVII.— PAXYLOMA, DeBreUsson. 



" Antennw filiform, not so long as the body, 13-jointed, basal joint rather the 

 stoutest and chalice-shaped, 2nd globose, 3rd long, the remainder decreasing in 

 length : palpi minute : head transverse : eyes large : thorax small and globose: 

 abdomen long and clavate : ovipositor shorter than the groove that receives 

 it: superior (anterior) wings with a long narrow stigma placed in the 

 marginal cell (areolet), which is of the same form ; submarginal cell 1, 

 arising at the angle of the marginal one, and extending to the posterior 

 marghi ; discoidal cells 2, the superior one reaching the stigma ; posterior 



' legs rather long; coxae and thighs slender; tibiae rather clavate; tarsi 

 thicker than the thighs, the basal joint longest, very long hi the 1st and 2nd 

 pair." — Curiis, I. c.
