TWO NEW GENERA OF SAND WASPS. 



By WILLIAM H. ASHMEAD. 



(Assistant Curator Department of Insects U. S. Nat. Museum.) 



Family NVSSONIDyE. 



FOXIA. 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 9 with a lateral tooth, lateral 

 margins of pygidium towards apex serrated; ventral segments 

 4-6 in I 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. 



(i) Foxia pacifica n. sp. r^ ? . 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 tibia; 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.

Type No. 5017, U. S. Nat. Mus. 



Family LARRID^E. 



MISCOPHINUS n. g. 



Allied to Sah'ostet/iHS Brauns, but the wings normal, the mar- 

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

 submeciian cell shorter than the median; cubitus in hind wings 

 originating beyond the transverse median; eyes large, extending 

 to base of mandibles, slightlv 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-
