HYMENOPTERA PARASITICA 357 



beneath. Terebra curved, a little longer than the petiole, which is alutaceous. The 

 abdomen is covered (especially the apex) with a pale pubescence. Wings hyaline ; 

 nervures and stigma pale testaceous ; areolet complete, scarcely petiolated. (Cameron.) 



The specimens taken by Mr Perkins measure only 4 mm. in length, but otherwise 

 agree very well with Mr Cameron's description. The antennae in the t are 28-jointed.

[?. Length 5 to 5.5 mm. Antennae in $ 26-jointed, in ? 29-jointed, the scape 

 pale beneath.] Very similar in coloration and size (except that it is somewhat smaller) 

 to L. blackburni, but differing from it in the head and thorax being densely covered 

 with silvery -white pubescence, on L. blackburni (especially on the thorax) it being very 

 sparse and the pleurae are almost glabrous ; the posterior median area of the metanotum 

 is narrower and longer ; the femora are of a much paler red, the four posterior tro- 

 chanters [except sometimes the first joint of the hind trochanters] are entirely yellow, 

 there is no black at the base of the hind femora, the black on the tibiae is lighter, the 

 four anterior tarsi are pale testaceous without any black, and the areolet is not only 

 longer, but is also somewhat wider ; the postpetiole is more strongly punctured, as are 

 also the second and third segments, and the apical segments are more densely covered 

 with white hair, the hair being also longer. The apex of the second segment and the 

 greater part of the third segment externally are testaceous. (Cameron.)

%. Length 6 mm. Black ; the mandibles, palpi, trochanters, knees and tibiae 

 (except at base and apex), and the spurs, yellowish-white ; femora and base and apex 

 of anterior tibiae reddish ; base of four posterior femora, base and apex of posterior 

 tibiae, blackish ; coxae and base of trochanters black ; anterior tarsi fuscous ; the base 

 of the tarsal joints pale. Abdominal segments at junction white ; ventral surface at base 

 yellowish. Head, thorax, and coxae almost opaque, faintly punctured, covered with a 

 white pubescence, which is especially long on the face. Abdomen semiopaque, very 

 finely punctured ; terebra as long as the four last segments together ; base of petiole 

 smooth, almost shining. The three basal areolae of metanotum are less strongly
