AMERICAN ENTOMOLOGY. Ill 



resemble those of the bee. The covering of the pupa is a thin 

 pellicle. 



Fabricius first applied the name Phihinthus ; but Latreille 

 divided the group which his predecessor established under that 

 name into two genera, retaining the appellation for the present 

 group, and applying that of Cerceres to such as have denticulated 

 mandibles, and the second cubital cellule petiolated. The former 

 were called /Simhlrphihs, and the latter Phihintlmx, by Jurine. 



The name of this genus is compounded of the Greek words 

 <^ih.»^, I love, and ^^fSof, a flower. 



Philanthus CANALICULATUS. — Specific character. Pale 

 yellow ; vertex, disk of the thorax, and incisures of the tergum 

 reddish -brown.

Desc. Body pale yellow ; vertex reddish-brown ; front with 

 two longitudinal reddish-brown lines passing through the base 

 of the antenna? ; antennae rufous, black at tip : mandibles black 

 at tip : superior wings with a longitudinal brownish line on the 

 middle from near the base to the tip ; radial cellule rounded at 

 tip, and at its inferior angle descending to meet the superior 

 angle of the second cubital cellule, which is triangidar : tergum 

 with a transverse groove on the middle of each segment, and a 

 marginal smaller one ; incisures reddish-brown. 



Obs. When traversing the Arkansaw region with 31ajor Long's 

 party, I obtained a single specimen of this insect, which is a 

 male ; it is so very similar in general appearance and color to 

 Ccrceris LiJentata nob., that but for its generic differences, I 

 should almost have been led to consider it as a mere sexual variety 

 of that species. But it cannot be placed in the genus Cerceris, 

 as the mandibles are entirely unarmed within, and the second 

 cubital cellule is not petiolated, and the eyes are not emar- 

 ginated.

Philanthus zonatus. — Specific character. Black : front, 

 two lines on the thorax and posterior submargifts of the segments 

 of the tergum, yellow : feet rufous.

Desc. Body above black : front yellow, with two black lines 

 descending from the black vertex to the ori'nn of the antennae :
