Family NYSSONID^E. 



FOXIfc n. g. 



Habitus of Nysson Latr. {sens, str.), but differs as follows : 

 The second and third submarginal cells each receiving a recur- 

 rent nervure, the first received by the petiolated second before 

 its middle, the second received by the third at its basal one-third; 

 forehead at middle with a tubercle or carina just above base of 

 antennae; ventral segments 4-5 in $ with a lateral tooth, lateral 

 margins of pygidium towards apex serrated; ventral segments 

 4-6 in % with a lateral tooth, the pygidium at apex tridentate, 

 the middle tooth minute, otherwise hind tibiae, scutellums, etc., 

 as in Nysson Latr., but not Paranysson, which I consider to be 

 a distinct genus. 



Dedicated to my friend, the energetic young hymenopterist, 

 Mr. Wm. J. Fox, of Philadelphia, Pa. 



{1) Foxia pacifica n. sp. rf $ . — Length 6-6.5 mm. Head and thorax black, 

 rugoso-punctate, the head, except vertex, collar, mesopleura and meta- 

 thoracic spines clothed with a dense silvery pubescence; mandibles, hind 

 legs, except coxae and abdomen, mostly rufous; four anterior legs except 

 the anterior tibiae within and their tarsi and the middle tarsi, which are 

 ferruginous, black ; the dorsal abdominal segments are narrowly mar- 

 gined with white at apex, while the three or four apical segments are 

 more or less black or blackish.

Family LARRID^E. 

 MISCOPHINHS n. g. 



Allied to Saliostethus Brauns, but the wings normal, the mar- 

 ginal cell not triangular, but as in Miscophus, subtruncate at apex; 

 submedian cell shorter than the median; cubitus in hind wings 

 originating beyond the transverse median; eyes large, extending 

 to base of mandibles, slightly convergent above ; mandibles 

 deeply excised beneath a little before the middle; maxillary palpi 

 6-jointed, the first joint the shortest, the following rather long, 

 subequal; labial palpi apparently but 3-jointed; clypeus not sepa-
