clypeus subtriincate, or slightly emarginate; joint 3 of anteniiiB about five, times 

 as long as 2, about one-fifth longer than 4 ; posterior margin of prothorax angu- 

 lar; metathorax rounded, with a faint median impressed line, its apex reflesed : 

 legs with numerous short spines, the front tarsi hardly ciliated ; claws large, with 

 a median tooth ; wings violaceous black or fuscous, with a slight purplish reflec- 

 tion, apical margin usually more clouded ; submedian cell of front wings longer 

 than median, of hind wings equaling, or a little shorter than, median, both meas- 

 ured on the dividing nervures; marginal cell lanceolate, cubital cells 2 and 3 sub- 

 equal, strongly narrowed above by curving transverse cuhitals, 2 usually a little 

 less strongly narrowed than 3, rarely subquadrate, 2 receiving the first recurrent 

 nervure a little beyond the middle, 3 receiving the second about the middle. 

 Length 8-15 mm. 



% .—Joint 3 of antennfe about four times as long as 2, equaling 4 ; claws large, 

 cleft ; wings a little less clouded, legs less spinose. Length 8-11 mm. 



Carlinville, Illinois; 19 9,10 S specimens. 



Differs from P. cethiops Cr. and relativus Fox by the posterior 

 margin of prothorax being angular; from P. philadelphicMS Cr. by 

 its smaller size, blacker color, clypeus of 9 not deeply emarginate, 

 joint 3 of antennae of S not longer than 4 ; from P. scelestus Cr. by 

 its venation, cleft claws of % , etc.

Oxybelus floridanus n. sp. 



\ _0f the same size, form and structure as 0. Isetus Say, and is perhaps a mere 

 variety of that species.' The ornaments the same : the black color of the legs 

 replaced by orange reddish so that the legs appear quite different; the abdomen 

 has fewer spots, one specimen with eight spots, the other with four; apical seg- 

 ment of abdomen rufous; otherwise quite as in 0. Isetus. Length 4-5 ram. 



Inverness, Florida; 2 % specimens. 



Notoglossa inoriiata n. sp. 



9 .—Clypeus with lateral dentiform angles and a median dentiform process, 

 beyond which it is smooth and shining : prothorax carinate; scutel and postscutel 

 carinate; squama as in Oxybelus; spine rather broad, emarginate ; basal segment 

 of abdomen with median impressed line; insect shining, rather closely and 

 coarsely punctured. Black, with thin white pubescence on face, cheeks and 

 sides; apical half of antenn®, tegulw, base of wing, apical joints of tarsi testa- 

 ceous; mandibles, anterior and middle tibije, and anterior tarsi yellow; apical 

 segment of abdomen red. Length 4 mm. 



% .—Resembles the female; mandibles, knees, anterior and middle tibise, apex
