of mandibles, posterior coxse, femora and tarsi, and apical abdominal 

 segment entirely brown; cheeks with a yellow mark adjoining mandi- 

 bles, wings brownish transparent ; veins and stigma dark brown. 



Type in American Entomological Society, Philadelphia, Pa. 

 Type locality Shasta County, Cal. 



Superfamily. VESPOIDEA. 

 Family TIPHIID^. 



Paratiphia algonguina, new species. The Algonquin Para- 

 tiphia. 



This is apparently the only species of Paratiphia in the east- 

 ern part of the United States. According to present knowledge 

 it seems to be confined to the State of New Jersey. This form 

 has been erroneously determined as P. albilabris Spinola, which 

 latter has hyaline wings and hails from California. From 

 P. clypeata Smith, formerly Tiphia, P. varipunctata Cameron, 

 P. fuscipennis Cam., P. robusta Cam. and P. fuscinerva Cam., 

 this species is readily separated by the nonconcolorous wings. 

 From P. dnodeccini/iaculata Cam. by the immaculate abdomen. 



Male 8 mm. long. Xearly all of the tegument shining black, punctate, 

 with the punctures ranging from adjoining to at least as far as three 

 puncture-widths apart, bedecked with silvery pubescence that nowhere 

 is so thick as to obscure the tegument and is made up of hairs the 

 longest of which are shorter than the 13th joint of the antennas, the 

 hairs also much thinner than the thinnest vein in the wings. 



Head a little wider than long ; eyes diverging above ; converging 

 below; malar space practically wanting: if straight lines were drawn 

 connecting the centers of the ocelli an obtuse-angled triangle would 

 be formed, shortest distance between the posterior ocelli apparently 

 equal to the shortest distance between the lateral ocellus and the nearest 

 eye margin; clypeus about twice as wide as long, yellow, with rather 

 distinct punctures from one to several puncture-widths apart, its anter- 

 ior margin seemingly depressed somewhat arcuately, convexly rounded; 

 mandibles falcate, rounded off at tips, with a rounded angle or vestigial 

 tooth on the inner margin near the apex, mostly yellow aJiove, brownish 

 at apex; antenn;e nearly of the same diameter throughout, the pedicel 

 distinctly narrower than the -cape or the first joint of the flagel, scape 

 rather oviform, equal in length to the length of the pedicel and the first 

 and second joints of the flagel combined, first and second joints of 

 flagel subequal in length, wider than long, the succeeding joints longer 

 than wide but only slightlj so or not much lonvr than wide, with the 

 exception of the apical joint, which is easily twice longer than wide. 

 Metathorax with a superior and posterior aspect in addition to its sides,
