PROCTOTRYPID^, 

 Bethylin^. 



Paralcelius, gen. nov. 



Female. Antennae 13-jointed, fully twice longer than the 

 head. Head twice longer than its width across the eyes, roundly 

 narrowed behind, obliquely in front. Eyes of moderate size, 

 placed in the centre, and about one-third of the length of the 

 head ; they are bare. Antennal scape about one-fourth of the 

 length of the head, as long as the following two joints united ; 

 stout ; the pedicle clearly longer than the 1st joint of flagellum, 

 narrowed at the base. Prothorax about three times longer than 

 the mesonotum, gradually widened towards the apex. Mesonotum 

 without furrows. Scutellum with a large fovea on either side at 

 the base. Metanotum long, transverse at the apex ; in the centre 

 are 3 complete longitudinal keels ; the sides are bordered by a 

 keel ; and there is a short one inside it, on the base. There are 

 2 closed basal cellules in the fore wings, the anterior clearly 

 longer than the posterior; the bounding apical nervure is obliquely 

 sloped, so that it is wider in front than behind ; there is a distinct 

 marginal vein, about 3 times longer than wide ; the stigmal vein 

 about the length of the marginal, dilated towards the apex ; the 

 apex of the wings sliortly ciliated. The basal segment of the 

 abdomen sessile, slightly longer than the 2nd, the following 3 

 equal in length. The outer tooth of the mandibles is acute, dis- 

 tinct ; the others I cannot make out satisfactorily. Tarsi longer 

 than the tibiae. 



May be known from Lcelius (an American genus), its nearest 

 ally, by the longer head, by the smaller, not hairy, eyes, aud by 

 the clavate stigmal vein.
