Female. — Length 5 mm. Labrum strongly rounded al the apex; 

 clypeus rather deeply semicircularly emarginate, lobes broadly t ii- 

 angular, rounded at the apex: supraclypeal area, raised, rounded; 

 middle fovea elongate, pointed toward the clypeus; antenna! fovea' 

 large, uniting with the supraclypeal fovees; antenna] furrow nearly 

 complete, narrow; ocellar basin well defined, though the ridges arc 

 not sharp; interocellar furrow poorly defined; crest broken although 

 not strongly so; third antenna] joint very little longer than fourth; 

 scutellar appendage irregularly punctured; cerci of median length, 

 tapering apically; sheath straight above, rounded below; teeth of 

 saw very small and weak; stigma slightly broader at base, sharply 

 rounded at apex. Black; mandibles (apices piceous), most of 

 clypeus, labrum, supraclypeal area, inner orbits to antennae, posterior 

 orbits to top of eyes (the orbits are dusky), legs (the tarsi dusky and 

 femora brownish) reddish-yellow; extreme angles of pronotum and 

 tegulse pallid. Wings hyaline, iridescent ; venation pale brown, 

 stigma pallid. 



Male. — Length 4 mm. Differs from the female as follows: Third 

 antennal joint slightly shorter than fourth, flagel pale beneath, and 

 stigma dark brown. Hypopygidium pale and sharply pointed. 

 The male is easily separated from brachycarpx by the pointed hypo- 

 pygidium. 



Type-locality. — St. John, New Brunswick. Three females and two 

 males collected July 18 by Mr. A. CI. Leavitt.

Subfamily J^MlSTUSINyE. 

 Tribe FENUSINI. 



Genus FENUSA Leach. 



In 1817 Leach " described the genus Fenusa and named only 

 Tentliredo (Emphytus) pumila King, which is therefore the type of 

 the genus. In 1846 Tischbein b in describing dohrnii referred it to a 

 new genus Kaliosyphinga. Dohrnii is therefore the type of Kaliosy- 

 phinga, the genus originally being monobasic. Kaliosyphinga 

 dohrnii Tischbein and T< nthredo (Emphytus) j>iimi/<i King are con- 

 generic, so the genera tire the same. Fenusa is the older name. 



Leach in the same paper' described the genus Messa and mimed 

 only Tenthredo (Emphytus) hortulana King, which is therefore the 

 type of the genus. Konow d does not include the genus Messa, but 

 places its genotype in the genus Fenusa and the genotype of Fenusa 

 in the genus Kaliosyphinga. The genus Fenusa, as defined by 

 Konow/' is Missa Leach, and Kaliosyphinga as treated by Konow* 

 and from the original description, is Fenusa Leach.
