AMERICAN HYMENOPTERA. 239 



short sharp spines directed outward and upward, superior face with nearly 

 straight ridges placed close together, only the central ridges prominent on the 

 posterior face which is reticulated; wings brownish irridescent, nervures black, 

 venation nearly as in tramosericus ; legs smooth, posterior tibiae not spinose. 



Abdomen. — First three segments with rather sparse, small, shallow punctures 

 on a minutely punctured surface, on the apical segments the minute punctures 

 become prominent and the larger shallow punctures almost disappear; spines of 

 apical segment very short and blunt 



Black; pi-ouotum with a median spot, tubercles, a short line on each side of 

 segments 1, 2 and 3 at apex, and a dot on each side of segment 4 yellowish white, 

 four anterior tibite with a whitish line in front.

CRABRONIDiE. 



Kntoniognatiiu»$ lenapeorum n. sp. 



9 . 5 mm. long. Head. — Polished, punctures rather sparse and small, a semi- 

 lunar depression between the lateral ocellus and the eye. the frontal impression 

 represented by a shallow pit; joints of the flagellum subequal, pedicellum equal 

 to the first joint of the flagellum or a little longer; O'elli forming a low triangle, 

 distance between posterior pair distinctly greater than the distance between 

 them and the nearest eye margin. 



Thorax. — Pronotum smooth and rounded, apparently impunctate ; dorsulum 

 with indistinct parapsidal grooves and sparse setigerous punctures; scutelluni 

 punctured much like the dorsulum ; pleura very finely and sparsely punctured ; 

 metathorax with the superior face deeply pitted and with irregular strong rugae, 

 posterior face rugulose and wtth a median triangular smooth depression; wings 

 clear, slightly brownish, the nervures and stigma black, transverse median nerv- 

 ure a little basad of interstitial with the basal nervure, the recurrent uervure 

 enters the submarginal cell a little beyond the middle, as does the transverse 

 cubitus enter the marginal cell. 



Abdomen. — Largely impunctate, the penultimate dorsal segment densely punc- 

 tured, the pygidium more densely punctured than the segment preceding; sec- 

 ond ventral segment rather sparsely punctured. 



Black; scape with a line in front; tubercles and four anterior tibite in front 

 yellow, tarsi and spurs brownish. Face below antennse covered with dense sil- 

 very pubescence, the other parts of the insect covered with thin pubescence that 

 does not hide the surface, the pubescence more abundant on the legs than on the 

 body.

Anothyreus panur^oifles n. sp. 



Related to ^4. {Crabro) lequalis, but differs in the more even punc- 

 tuation of the dorsulum and particularly by the first .segment ap-
